Important: The 50% deposit match, up to $1,000 first-deposit match and the Keep Your Million contest are no longer either/or offers. Eligible new users can receive both promotions, although the size of the deposit match depends on their state. Underdog has announced a deposit match of up to $250 for Predictions-only states, but the match percentage and launch details are still to be confirmed.
Underdog promo code: Get a 50% match up to $1,000
The Underdog promo code SICOM gives new users a 50% first-deposit match up to $1,000 in bonus funds, which you can claim alongside the Underdog Keep Your Million contest entry. The bonus can be used across all eligible Underdog products, including Underdog Predict, Pick'em, Best Ball, and drafts.
I've played across Underdog's different game formats, and the ability to use the bonus on the app, where you can access predictions and fantasy contests, is one of the offer's biggest advantages. If you only want to speculate via Underdog Predict, you can use the new 50% deposit bonus entirely on NFL, MLB, NBA, and other sports trades. However, if you enjoy Pick'em or Underdog's draft contests, such as best ball, you can also use your up to $1,000 deposit bonus funds on those classic contests as well.
For this review, I'll focus on Underdog Predict, how the Underdog welcome offer works, and the flexibility to use your bonus funds across prediction markets and other eligible Underdog games.
✍️ How to claim the Underdog $1,000 bonus
Claiming the Underdog $1,000 bonus takes just a few steps:
- Create a new Underdog account using promo code SICOM.
- Make a first deposit of at least $10.
- Receive a 50% match on your qualifying deposit.
- Deposit $2,000 to receive the maximum $1,000 in bonus funds.
- Use your bonus funds on Underdog Predict or other eligible Underdog products.
I've found Underdog Predict easy to navigate and rate it as one of our top prediction market apps for new users, especially if you're already familiar with Underdog Pick'em, a game with principles similar to prediction trading. New Underdog users can immediately use the bonus funds on event contracts covering the NFL, NBA, MLB, and other major sports.
Underdog promo code terms explained
The $1,000 Underdog promo is credited as promotional bonus funds and can be used across eligible Underdog products, including Underdog Predict. I've found the offer fairly flexible, but there are a few important rules to understand before deciding how much to deposit.
- 50% match up to $1,000: Underdog matches half of your qualifying first deposit. You need to deposit $2,000 to receive the maximum $1,000 bonus.
- State availability: The $1,000 offer is available in AL, AK, AZ, AR, CA, CO, DE, DC, FL, GA, IL, IN, KS, KY, MA, MD, MI, MN, MS, MO, NE, NH, NJ, NM, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WV, WI, WY. The $250 offer is for those located in CT, HI, ID, IA, LA, ME, MT, WA.
- 1x playthrough: The requirement applies to your deposit and bonus combined. For example, a $100 deposit earns a $50 match, creating $150 in required qualifying playthrough.
- 14-day deadline: You have 14 days to complete the playthrough. Any promotional balance that hasn't qualified by the deadline can be forfeited.
- Underdog Predict eligible: You can use the bonus on eligible Underdog Predict markets as well as qualifying fantasy products available in your state.
- Bonus isn't immediately withdrawable: Promotional funds remain subject to the playthrough requirement rather than functioning like unrestricted cash.
- Winnings can be withdrawn: Eligible winnings generated while completing the playthrough can be withdrawn before you've finished the entire requirement.
- Your deposit isn't forfeited after 14 days: Failing to finish the requirement can cost you the remaining promotional balance, rather than automatically wiping out your original cash deposit.
- Claim alongside Keep Your Million: New users can now claim the 50% deposit match bonus alongside the Keep Your Million contest entry offer.
How the Underdog 50% deposit match works
The Underdog promo code SICOM matches 50% of your first deposit, up to $1,000 in bonus funds.
The key point is that the 1x playthrough requirement applies to your deposit and bonus combined, and you have 14 days to complete it.
Underdog deposit match and playthrough examples
| First deposit | 50% bonus | Total balance | Required playthrough |
|---|---|---|---|
| $10 | $5 | $15 | $15 |
| $50 | $25 | $75 | $75 |
| $100 | $50 | $150 | $150 |
| $500 | $250 | $750 | $750 |
| $1,000 | $500 | $1,500 | $1,500 |
| $2,000 | $1,000 | $3,000 | $3,000 |
For example, if I deposit $100, Underdog adds a $50 bonus. That gives me $150 for playthrough purposes, meaning I need to generate $150 in qualifying entry fees within 14 days.
You don't need to deposit the full amount to receive a bonus, but the amount of your deposit bonus does determine the amount of bonus you receive.
What happens if I don't complete the playthrough in 14 days?
If you don't meet the requirement within 14 days, Underdog can forfeit your remaining promotional bonus. The requirement doesn't mean your original deposit simply disappears after 14 days; it applies to qualifying the promotional balance.
A few details are especially useful to know:
- Winnings can be withdrawn: Winnings generated during the playthrough period may be withdrawn before the entire requirement is completed.
- Bonus funds aren't immediately cash: The promotional balance remains subject to the offer's playthrough rules.
- You can opt out: You can contact Underdog support to cancel your participation if you don't plan to complete the requirement, but you'll forfeit the bonus.
- Watch the 14-day deadline: I recommend tracking your remaining qualifying volume, particularly if you claim a larger match.
Example:
I deposit $2,000 on Underdog and earn $1,000 in bonus funds from the 50% deposit bonus, creating a $3,000 playthrough requirement.
Over my first 14 days playing on Underdog and Underdog Predict, I used $500 of the bonus funds on trades or entries and made $500 in profit (cash). The extra $500 in profit (cash) I have earned is now available to withdraw.
However, the remaining $500 in bonus funds is not withdrawable, and I have only seven days left in my original 14-day timeframe to complete my playthrough requirement and use them before they expire.
My take on the Underdog $1,000 bonus after using it
After claiming and clearing the Underdog $1,000 bonus myself, it's evident that the 50% deposit match offers excellent value, but it's equally evident that not all users should deposit $2,000 just because that's what unlocks the maximum bonus.
I deposited the full $2,000 and received the $1,000 match. I cleared the required playthrough by using Underdog every day and spreading my activity across multiple products, including Underdog Predict, best ball entries, and Pick'em. That's realistic for an active Underdog user, but it creates a substantial $3,000 playthrough requirement that must be completed within 14 days.
For someone new to Underdog, I'd start with an amount that matches how much you actually expect to play:
- Occasional user: A smaller deposit makes the 14-day requirement much easier and less stressful to manage.
- Regular sports fan: Deposit based on your normal activity rather than chasing the $1,000 maximum.
- High-volume user: The full $2,000 deposit can make sense if you're confident you'll naturally clear $3,000 in qualifying play.
The 50% match scales with your deposit, so there's no need to maximize it to get value. In my experience, the $1,000 bonus is achievable, but I'd rather leave some bonus on the table than deposit or play more than I'm comfortable with just to clear a promotion.
Bottom line: Only deposit and play with money you can afford to lose. Don't increase your spending simply to maximize the bonus or complete the playthrough requirement.
Underdog Keep Your Million: Get it with the $1,000 deposit match
Underdog Keep Your Million is a free-to-play survival game. Eligible users who make a deposit on Underdog of $10 or more get access to a virtual $1 million pot and challenges them to preserve as much of it as possible across up to 20 Higher/Lower player questions.
For new users, the big advantage is that Keep Your Million can now be claimed alongside Underdog's 50% deposit match bonus. In most eligible states, that means you can sign up with promo code SICOM, get a 50% first-deposit match up to $1,000 in Bonus Funds, and also participate in Keep Your Million when you make a deposit of $10 or more.
Keep Your Million works very differently from the deposit bonus. Everyone starts with the same virtual $1 million pot, and the amount you ultimately receive depends on how much you can preserve through the game. Survive all 20 questions and whatever remains becomes Underdog Bonus Funds.
How does Underdog Keep Your Million work?
Keep Your Million is essentially a 20-question survival game. For each question, Underdog gives you a Higher/Lower player projection and requires you to allocate your entire remaining balance between the two possible outcomes.
- Start with $1 million: Eligible users begin with a virtual $1 million Keep Your Million pot.
- Pick a question: Choose an available player projection, such as whether Patrick Mahomes will throw Higher or Lower than 275 passing yards.
- Split your million: Allocate your entire remaining pot between Higher and Lower. You can put 100% on one outcome, split it 50/50 or choose anything in between.
- Lock in your allocation: Submit your selection before the game starts. Once submitted, it can't be changed or canceled.
- Keep the winning side: After the question settles, only the amount allocated to the correct outcome remains in your pot.
- Survive up to 20 questions: Your remaining balance carries forward to the next question. Make it through all 20 and your final balance is awarded as Underdog Bonus Funds.
Underdog Keep Your Million strategy
The key to Keep Your Million strategy is adjusting how much you allocate based on how confident you are in each Higher/Lower outcome. You don't need to split your virtual balance evenly every round.
Tip #1 - Adjust your wager sizes when confident
If I think one side is statistically more likely to hit on a certain pick, or that it offers a +EV opportunity, I'd allocate a larger percentage of my virtual balance to that side or outcome.
Tip #2 - Don't be afraid to play defense
On the flip side, if I get a pick/projection that looks closer to a true 50/50 or I'm less confident than I was on previous picks, I'd advocate for a more balanced split to reduce variance look to just maintain my balance until the next question.
Tip #3 - Be patient
The goal isn't necessarily to be aggressive on every question. You need to survive all 20 rounds, so risk more of your balance when you believe you have an edge and protect it when you don't. Going 100% to one side may preserve your entire pot when you're right, but one bad read also ends your Keep Your Million run.
Keep Your Million example
Say I have $500,000 remaining and choose a question asking whether an NFL quarterback will throw Higher or Lower than 275.5 passing yards.
Example 1: I could allocate $350,000 to Higher and $150,000 to Lower. If the quarterback finishes Higher, I keep $350,000 and take that balance into my next question. If he finishes Lower, I survive, but my new balance drops to $150,000.
Example 2: I could also go all-in and put the entire $500,000 on Higher. I'd preserve the full $500,000 if I'm correct, but I'd be eliminated if Lower wins.
That's what makes Keep Your Million more than simply trying to pick 20 winners. You control how much of your million you're willing to risk on every question. More balanced allocations can improve your chances of surviving, while aggressive allocations give you a better opportunity to reach the end with a substantial balance.
Keep Your Million rules at a glance
- Starting balance: $1 million virtual pot
- Cost to play: Minimum $10 deposit to access the game for eligible users.
- Questions: Up to 20
- Pick type: Higher/Lower player projections
- Allocation: Your entire remaining pot must be allocated on each question
- Maximum reward: Up to $1 million in Underdog Bonus Funds
- Cash value of starting pot: $0
- Zero balance: Eliminates you from the promotion
- Selections: Lock when submitted and can't be changed or canceled
- Final balance: Converts to Underdog Bonus Funds after successfully surviving all 20 questions
- Bonus playthrough: 1x
- New-user eligibility: Can be claimed alongside the eligible first-deposit bonus
- Existing users: Most existing Underdog users are also eligible for Keep Your Million
Remember, Underdog isn't depositing $1 million in withdrawable cash into your account when you start. The $1 million is a virtual promotional balance used to play Keep Your Million. You must make it through all 20 questions to receive your remaining balance as Bonus Funds, and your actual reward depends on how much of the original million you preserve.
Can I Get Keep Your Million and the $1,000 Underdog Bonus?
Yes. Eligible new users can now get both Keep Your Million and Underdog's first-deposit bonus. You no longer need to choose one promotion at sign-up.
In most states where Underdog operates, new users can get a 50% first-deposit match worth up to $1,000 in Bonus Funds and receive access to Keep Your Million. The two promotions then work independently.
The deposit match gives you predictable value based on your first deposit. A $100 qualifying deposit, for example, earns a $50 match, while a $2,000 deposit qualifies for the maximum $1,000 match.
Keep Your Million gives you substantially more potential upside without requiring you to deposit $2,000 to chase its maximum value. Instead, eligible users who deposit $10 or more will get access to the game, where everyone starts with the same virtual $1 million and your final reward is determined by how much you can protect across 20 questions.
My take: There's no longer a reason to decide which Underdog promotion is better because eligible new users can take advantage of both. Use the up to $1,000 deposit match for the guaranteed promotional value tied to your deposit, then treat Keep Your Million as a separate opportunity to earn additional Bonus Funds. The latter has much greater potential upside, but unlike the deposit match, you can also finish the game with nothing if your balance reaches zero.
How to claim the Underdog promo code
I claimed the Underdog promo code SICOM with a $2,000 deposit, which unlocked the maximum $1,000 bonus. You don't need to deposit that much—the 50% match scales with your first deposit, so choose an amount you're comfortable playing through.
Here's how I claimed and used the offer on Underdog, and how I used my bonus across Underdog Predict and the rest of the platform.
1. Sign up for Underdog
Open Underdog through one of the links on this page and create a new account. Enter the Underdog promo code SICOM during registration and complete the required identity verification.
2. Deposit and get a 50% match
Make a first deposit of at least $10. Underdog matches 50% of your deposit in bonus funds, up to $1,000.
I deposited $2,000 and received the full $1,000 match, giving me a playthrough requirement of $3,000. You can deposit less and receive the same 50% match at a more manageable level: for example, a $500 deposit would get you a $250 bonus with a $750 playthrough requirement.
I used online banking for my deposit, which is a good option if you plan to use the bonus on Underdog Predict. Underdog also accepts credit/debit cards, Apple Pay, Google Pay, PayPal, and Venmo, although PayPal and Venmo deposits currently can't be used for prediction-market entries.
3. Use your bonus on Underdog Predict
Once credited, you can put your bonus funds to work across eligible Underdog products. I spread mine across several game types, including Underdog Predict, rather than trying to complete the requirement in one place.
Underdog Predict lets you trade sports event contracts covering the NFL, NBA, MLB and more, making it one of the most relevant ways to use the new offer.
4. Complete the playthrough and withdraw
You have 14 days to complete 1x playthrough of your deposit and bonus combined. In my case, that meant $3,000 in qualifying volume.
I cleared the requirement by playing regularly across multiple Underdog products. Once you're ready to withdraw eligible funds, available methods include:
- Visa or Mastercard debit card
- Trustly / online banking
- PayPal
- Venmo
My advice: Don't deposit $2,000 solely to chase the maximum $1,000 bonus. Pick a deposit amount that gives you a playthrough requirement you can comfortably complete within 14 days.
Underdog promo code vs. other prediction market bonuses
The Underdog promo code SICOM stands out from most prediction market offers because it allows new users to claim two offers. The 50% deposit match can reach $1,000 in bonus funds, which you can unlock by using it on entries across Underdog Predict and fantasy contests. New users also get access to the Keep Your Million contest, where you attempt to maintain as much of your starting $1M virtual pot over 20 Higher/Lower questions.
When all is said and done, the Underdog bonus offers a much higher maximum than the fixed welcome bonuses offered by most competitors.
Here's how Underdog compares with other prediction market promos I've tested for September 2026.
| 🐶Underdog | 🟢 Kalshi | 🔵 Polymarket | 🟠 OG.com | |
|---|---|---|---|---|
| Welcome bonus | 50% deposit match up to $1,000 | Trade $25, get $35 bonus | Deposit $10, get $20 trading bonus | Trade $10, get $10 bonus |
| Bonus type | Deposit match | Trade and get | Deposit match | Trade and get |
| Top feature | Prediction markets with fantasy contests | Top-rated trading app | Legal trading on real-world events | Integrated social features |
| Payout speed | Within 24 hours | Within 24 hours | Within 24 hours | Within 24 hours |
| Min. deposit | $10 | $1 | $10 | $10 |
| App Store rating | 4.8⭐ | 4.8/5 ⭐ | 4.6/5 ⭐ | 4.4/5 ⭐ |
Underdog promo code vs. Polymarket promo code
The Polymarket promo code is a better fit if you prioritize market depth and want to trade exclusively on prediction markets. Polymarket offers a simple and easy-to-claim deposit match and a much larger selection of sports, politics, economics, and other real-world events.
Overall, Underdog has the clear edge and offers strong product flexibility. Its deposit match can reach $1,000, and you can use the promotional funds across Underdog Predict and its other eligible sports products.
Underdog promo code vs. Kalshi promo code
Kalshi remains one of my preferred pure prediction market platforms, with extensive sports and non-sports markets and a trading-focused interface. Its welcome offer is also easier to maximize with the Kalshi promo code because it requires considerably less upfront money.
The Underdog promo code has much more upside if bonus size is your priority, but you'll need to deposit and complete more qualifying volume. Overall, the choice is between getting more value on your bonus for sports and fantasy contests or accessing one of the best overall prediction markets for sports and real-world trading on Kalshi.
Underdog promo code vs. OG.com promo code
OG.com is another sports-focused alternative, particularly if you want a prediction market platform built primarily around sports trading and social features.
Underdog offers a broader overall sports experience. I've been able to move between Underdog Predict, Pick'em, and drafts while using the 50% deposit match, which gives me much more potential promotional value than the OG promo code welcome offer.
Underdog promo code vs. ProphetX promo code
The ProphetX promo code is worth considering if you primarily want to trade sports. Its exchange-style platform, sports market selection, and 0% fees on profitable parlays make it a more specialized alternative to Underdog.
The biggest difference is the welcome bonus: ProphetX offers a smaller fixed reward with a low qualifying threshold, while Underdog lets you scale your 50% match up to $1,000.
Underdog promo code vs. Novig promo code
Novig also focuses heavily on sports and has a lower barrier to unlocking its welcome bonus through the Novig promo code. That makes it appealing if you want to test a prediction platform without committing much money upfront.
I'd favor Underdog for higher bonus potential and variety. The ability to use the promotion across Underdog Predict and other eligible products gives you more ways to clear the offer, especially if you're already an active Underdog user.
Underdog promo code vs. Gemini Predictions promo code
The Gemini Predictions promo code gives you a smaller total amount of up to $70 in Predict Cash. Underdog is better for those who want a larger bonus to get started.
Underdog vs. prediction market referral bonuses
If you want to make money by inviting friends to the site you trade on, you'll want to learn more about the Kalshi referral code, the Polymarket referral code, and the Crypto.com referral code. All three can set you up for big rewards when you share your unique links with friends.
Underdog Predict review
Underdog Predict brings prediction-market trading into the same Underdog app as Pick'em and fantasy contests. It lets you buy event contracts tied to sports and other real-world outcomes, with prices changing as the market moves.
I've used Predict alongside Underdog's fantasy games, and its biggest advantage is accessibility. If you already know the Underdog app, there isn't much of a learning curve, and the new Underdog welcome bonus, a 50% deposit match up to $1,000, can now be used on eligible prediction markets.
What is Underdog Predict?
Underdog Predict is a new trading platform and a federally regulated feature within the main Underdog Sports app that allows users to trade 'Yes' or 'No' contracts on team and player outcomes in sports, as well as other real-world events.
Underdog Predict operates within the federal derivatives framework overseen by the Commodity Futures Trading Commission (CFTC). UDM, LLC, doing business as Underdog Predict, is registered as a Futures Commission Merchant (FCM) with the CFTC and is also regulated by the NFA.
Underdog also owns Underdog Exchange (UDX), a CFTC-registered Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO). Underdog acquired the Aristotle Exchange entities in March 2026 and launched prediction markets on its own exchange in July 2026.
How Underdog Predict works
Instead of sportsbook odds, Predict uses contracts generally priced between $0.01 and $0.99. A winning contract settles at $1, while a losing contract settles at $0.
For example, suppose I find an NFL contract asking whether Buffalo will beat Kansas City:
| Trade | Example |
|---|---|
| Will Buffalo beat KC? | Yes |
| Contract price | $0.62 |
| Contracts purchased | 10 |
| Total cost | $6.20 |
| Winning settlement | $10 |
| Potential profit | $3.80 |
Paying $0.62 also indicates roughly a 62% market-implied probability. If Buffalo wins and the contract settles Yes, my 10 contracts are worth $10. If the outcome settles against me (Buffalo loses), they settle at $0, and I lose my entire investment.
You don't necessarily have to wait for settlement either. Eligible positions can be closed early when trading is available, giving Underdog Predict more flexibility than simply submitting a fantasy pick and waiting for the result.
Best Underdog Predict features
- 🏈 Sports-first selection: Trade the NFL, NBA, MLB, NHL, college sports, soccer, tennis and other major competitions.
- 📈 Live market pricing: Contract prices can move between purchase and settlement as probabilities and market conditions change.
- 💵 Early exits: Sell eligible positions before an event settles when sufficient liquidity is available.
- 🔗 Prediction combos: Combine multiple eligible Prediction Picks into a single position for a larger potential payout.
- 🔀 Fantasy + Predict combos: Certain entries can combine a Prediction Pick with Fantasy Picks, something that differentiates Underdog from standalone prediction exchanges.
- 📱 One Underdog app: Move between Predict, Pick'em and drafts without managing a separate prediction-market account.
How to make a trade on Underdog Predict
I've found placing a Predict trade takes only a few steps:
- Open Underdog and select Team Picks.
- Choose the sport, game or event you want to trade.
- Select the outcome you think will occur.
- Review the current contract price and potential payout.
- Choose your position size and submit the trade.
Prices can move, so I always check the displayed contract cost again before confirming. Also remember that sports betting and prediction markets are not the same thing. Make sure to read our prediction markets vs. sports betting guide for a deeper look at the differences between the two.
Underdog Predict combos
Combos are one of the more interesting parts of Underdog Predict. Instead of limiting yourself to a single outcome, you can combine eligible predictions into one entry.
Underdog currently supports prediction market parlays with up to four Prediction Picks allowed in your multi-leg trade. It also offers Combo entries, which can pair one Prediction Pick with multiple eligible Fantasy Picks.
For example, an NFL combo could incorporate a team outcome from Predict alongside fantasy selections based on a quarterback's passing yards and a receiver's catches.
That crossover between prediction markets and Underdog's established fantasy product is a meaningful distinction from pure exchanges such as Kalshi or Polymarket.
What can I trade on Underdog Predict?
Sports are the main attraction, but Predict isn't limited to games. Current categories can include:
- NFL and college football
- NBA and college basketball
- MLB
- NHL
- Soccer
- Tennis
- Politics
- Weather
- Economics and business
- Entertainment and awards
Within sports, I've found game-level outcomes and player markets particularly useful. Depending on availability, these can include contracts resembling familiar moneylines, spreads, and totals, as well as outcomes tied to individual player performances.
Can I trade NFL prediction markets on Underdog?
Yes. Underdog Predict offers NFL prediction markets, allowing eligible users to trade event contracts on NFL games, players, and other football outcomes directly through the Underdog app.
NFL traders can find markets throughout the season, including:
- NFL game markets: Trade Yes/No contracts tied to the outcomes of upcoming games.
- NFL player markets: Trade player-based outcomes, including markets tied to passing, rushing, receiving, touchdowns, and other stats when available.
- NFL futures: Longer-term markets can cover season awards, team performance, playoffs, and other season-long outcomes.
- Prediction parlays: Combine up to four eligible prediction selections into one entry for a larger potential payout.
- Live NFL markets: Eligible markets may remain available after games begin, giving you opportunities to trade as prices react to the action.
Underdog also stands out because Underdog Predict and Underdog Fantasy are available within the same app. That means NFL fans can move between prediction markets and Underdog's Pick'em, DFS, and Best Ball products without using separate platforms.
Does Underdog Predict have a welcome bonus?
Yes. This is one of the biggest changes to the product in 2026.
New users can claim Underdog promo code SICOM for a 50% first-deposit match up to $1,000 in bonus funds, and the promotional funds can be used on eligible Underdog Predict markets.
That makes the current promotion particularly useful if Predict is your primary reason for joining Underdog. You don't have to claim a fantasy-only bonus and then switch products—the new offer can be put to use directly on eligible event contracts, working toward the promotion's playthrough requirement on one of the top NFL prediction market apps.
Where is Underdog Predict available?
Underdog Predict is currently available in 39 states plus Washington, DC. Users must be 18+ and physically located in an eligible state when trading Prediction Picks.
| Alabama | Alaska | Arkansas | California |
| Connecticut | Delaware | Florida | Georgia |
| Hawaii | Idaho | Illinois | Indiana |
| Iowa | Kansas | Louisiana | Maine |
| Minnesota | Missouri | Montana | Nebraska |
| New Hampshire | New Mexico | New York | North Carolina |
| North Dakota | Oklahoma | Oregon | Rhode Island |
| South Carolina | South Dakota | Texas | Utah |
| Vermont | Virginia | Washington | Washington, DC |
| West Virginia | Wisconsin | Wyoming |
One quick note for new users: eligibility depends on your physical location, not your state of residence. For example, California sports betting and Texas sports betting remain unavailable through legal online sportsbooks to residents, but eligible users residing in California and Texas can access Underdog Predict in both states. The same distinction applies to Georgia sports betting, while Underdog Predict also provides an alternative in the Florida sports betting market, where traditional sportsbook choice remains limited.
Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, and Washington are also notable because Underdog Predict is available there, even though Underdog Pick'em and Drafts are not.
Availability varies by location and product, so always confirm that Underdog Predict is available where you're physically located before trading.

Underdog Fantasy review
I've played and tested most fantasy games on the Underdog Fantasy app, including a few of its massive season-long NFL best-ball contests. I'll share my thoughts on why it's such a great option for anyone looking to get started with season-long and daily fantasy draft games, or use it for single-user daily fantasy Pick'em contests.
What is Underdog Fantasy?
Underdog Fantasy is a true all-in-one destination for anyone interested in competing in daily and season-long fantasy games across major sports leagues. The app has draft-friendly options for season-long and daily fantasy contests, along with single-user daily fantasy Pick'em games available almost nonstop.
Key features
What I like most about Underdog Fantasy is that almost every time I open the app, I can invest in short- or long-term fantasy games. Season-long best ball contests run year-round, and Underdog's massive NFL Best Ball Mania VII contest is set to award $2M to first place this season.
My list of favorite features on Underdog Fantasy include:
- Season-long NFL ball contests with entries from $5 up to $500.
- Massive prize pools for those interested in large, multiple-entry contests.
- In-app and on-site fantasy rankings with up to date player ADPs
- Daily draft contests for all major sports (NFL, PGA, NHL) for those who love drafting over the traditional salary cap format on most DFS sites.
- Expansive Pick'em contests that covers all major sports and niche markets such as golf, esports, WNBA, League of Legends (LoL), and more.
- Consistent array of profit boosts and reward tokens for Pick'em lineups.
- Live tracking feature where you can track Pick'em lineups and Draft entries.
Underdog Fantasy pros and cons
✅ Pros (what works)
- Best Ball leadership: It hosts some of the largest fantasy tournaments globally, such as the $15 million Best Ball Mania.
- High payout multipliers and boosts: Underdog often provides better odds than competitors for Pick'em games and regular boost offers.
- User experience: One of the highest App Store ratings among fantasy operators. Noted for its modern design and intuitive navigation.
- Contest formats: Unique games like 'Rivals' (picking between two players with a spread) and 'Battle Royale'.
- Transparent "Rake": Underdog is known for displaying the site fee (rake) for its fantasy contests, helping serious players calculate the cost of entry.
⚠️ Cons (what doesn’t)
- Slow withdrawal processing: Several methods, such as PayPal and Venmo, may require verification emails, which can slow withdrawals.
- Aggressive account limiting: Accounts can be limited after significant wins in Pick'em, often cited as "Terms of Service" violations, with no specific details provided.
- Limited customer support: No phone number for support. Users must rely on live chat or email, which have limited authority to resolve complex disputes.
Underdog Fantasy app experience
The Underdog Sports app has always been a mainstay for me. Even after taking a break from the season-long grind of NFL fantasy games, I'd still use the app for Pick'em lineups almost daily, or even enter the odd daily draft just because the draft process is so easy on mobile.
Underdog has done well in expanding their market coverage, now offering regular live Pick'em markets for all major sports.
My top features of the Underdog Sports app include:
- Lightning fast draft response where quick decisions are needed.
- Clear multipliers that make Pick'em payouts easy to track.
- Excellent contest tracking in the live section so I always know the status of my lineups.
- Some of the largest best ball contests available for NFL and NBA season-long.
- Consistent boost offerings that make games more profitable.
🍎 Underdog iOS app
Underdog Sports has one of the highest-rated daily fantasy apps in the industry. It's currently holding a 4.8 rating on the App Store, based on over 317K reviews.
🤖 Underdog Android app
The Underdog Sports app has a strong rating in the Google Play Store as well. With 32.5K reviews, it's maintained a strong 4.6 rating.
🐕🦺 Underdog customer support
Underdog claims to provide 24/7 customer support; however, the support is limited to one or two options, neither of which is by phone.
The live chat icon at the bottom of the page will connect you with a support agent. However, you'll need to go through an AI screening process for your issue before connecting, which can be time-consuming. You can also send an email, but I've found responses can take anywhere from a few hours to over a day.
- Live chat: Yes
- Email: support@underdog.com
- Phone: N/A
- X (Twitter): @UDSupport
✍ SI Expert analysis: I found Underdog support great for resolving small issues, usually a withdrawal that was 'stuck' or taking longer than normal. However, with larger problems that involved contest entry issues or payouts often they were far less helpful. This is an area I'd like to see them take more seriously in the future.
Does Underdog offer promos for existing users?
As a top social platform for fantasy, drafting, Pick'em, and predictions, Underdog shines with a consistent offering of existing user bonuses.
I received profit boosts for Pick'em lineups on a near-daily basis, along with reload bonuses for the entire site at critical times of the year (start of NFL and playoffs).
I went through and explained all of the best Underdog current user promos, so you'll know what to expect when you sign up:
| Underdog promo | Offer |
|---|---|
| 💰 Up to $1,000 deposit bonus | New users can currently get up to $1,000 in Bonus Cash with their first deposit using code SICOM. |
| 🚑 Pick’em Rescues | Eligible Pick’em entries may receive protection when a selected player leaves early because of an injury. Rescue eligibility and the exact refund treatment depend on the promotion. |
| 🚀 Pick’em boosts | Underdog regularly offers boosts that increase the potential payout or multiplier on eligible Pick’em entries. Boost size and maximum entry amount vary by promotion. |
| 💰 Free picks & discounted picks | Underdog frequently offers special player selections with reduced lines or promotional values. |
| 😅 No Sweat Tokens | Apply an eligible No Sweat Token before entering. If the entry loses, Underdog can return the qualifying amount as Bonus Cash, subject to the token's maximum entry and other terms. |
| 🔓 Pick’em specials & discounts | Underdog runs rotating specials such as discounted player lines and promotional Pick’em offers. These can change by sport, slate, and user. |
| 🦅 Vulture Protection | During football season, select players can receive Vulture Protection, designed to protect eligible entries when another player scores a short-yardage rushing touchdown. |
| ➕ Reload bonuses | Existing users may occasionally receive targeted deposit or reload offers. These aren't guaranteed for every account, and the percentage match, maximum bonus and playthrough terms can vary. |
| 📱 Social media & app promos | Underdog regularly promotes limited-time boosts, specials, and other offers through the app and its social channels. |
| 👥 Refer-a-friend offers | Underdog may offer referral rewards for inviting eligible new users. |
Underdog contests and markets
Signing up with the Underdog Sports app will allow you access to a huge variety of fantasy contests and prediction markets.
I outlined my favorite contests and markets so you can see why Underdog Sports has become the go-to mobile spot for anyone looking to access daily fantasy drafts and contests, Pick'em, and predictions on one app.
▶️ Pick'em contests
Pick'em contests require you to build an entry with 2 to 8 players' stats, predicting whether each player's total you choose will be "Higher" or "Lower" than the projected line. These are similar to how you would build a parlay on traditional sportsbooks.
- Standard picks: The classic Higher/Lower format, where you choose a side on individual player stats like points, rebounds, or touchdowns.
- Rivals: Head-to-head player matchups where you pick which of two players will outperform the other in a specific stat. These often include a "handicap" (e.g., Player A +5.5 points vs. Player B) to balance the matchup.
- Scorchers: Higher-payout picks where you choose players to exceed a significantly higher-than-average stat line (e.g., a player to score 40+ points instead of their standard 25.5).
- Ladders: Entries where your payout increases with each "rung" or pick you get correct.
- Champions: Peer-to-peer contest where you can select up to 8 player stats to win up to 500x your money.
- Streaks: A mode where you try to win consecutive picks to reach a grand prize of up to 1,000x your money, with a "Cash Out" option available.
✍ SI Expert analysis: Underdog is great at providing Pick'em promos for its current users, including daily boosts for specific sports. Use them to try out a new sport, as the increased payout will make the transition into a new market a little easier.
📝 Draft-Style contests
Underdog's reputation was built on the back of its huge offering of snake-draft formats, where you compete against other users in a single draft room. You'll find these contests still available on the site in several different formats.
- Best Ball: Season-long or tournament-style drafts where you do not need to manage your lineup. Underdog automatically starts your highest-scoring players each week.
- Best Ball Mania (BBM): Large-scale NFL tournaments (e.g., $15M prize pool) with multiple advancement rounds leading to a Week 17 final. Best Ball Mania VII is now available with a $2M first prize.
- The Big Board/Bigger Board: Pre-draft NFL contests where you draft players before the actual NFL draft occurs.
- Daily Drafts: Fast-paced snake drafts for a single night's slate of games.
- Battle Royale: A hybrid format that combines a 6-round snake draft with DFS-style tournament scoring for a single week or day.
- The Eliminator: A survival-style draft tournament where the lowest-scoring teams in a group are eliminated each week until a winner is crowned.
- The Scramble: A golf-specific best ball format (e.g., PGA Scramble) where rosters are built through a snake draft for multi-event tournaments.
✍ SI Expert analysis: Underdog uses 0.5 PPR scoring in NFL which can have a dramatic effect on player values for WRs and RBs. Ensure you go over all the terms and have a good look at ADP rankings before entering.
🔮 Prediction markets
Underdog Predict offers trading markets across almost all major sports, including the NFL, NBA, MLB, NHL, PGA, Soccer, and College Sports. These offerings include regular game markets and player stats.
- Team outcomes for predictions:
- Moneylines: Buying contracts on a team to win a specific game outright.
- Spreads: Trading on whether a team will cover a specific point, run, or puck line (e.g., "Panthers +3.5").
- Game totals: Predicting if the combined score of a game will be Higher or Lower than a set number.
- Player performance markets for predictions:
- Contracts based on individual player stats, such as a quarterback's passing yards or a player scoring a touchdown.
- Futures markets for predictions:
- Season win totals: Trading on how many total games a team will win over a full season across the NFL, NBA, MLB, and more.
- Championships: Predicting winners of major events like the Super Bowl or World Series.
- Supported leagues:
- NFL, NBA, NHL, MLB, College Football (CFB), College Basketball (CBB), Soccer, and Tennis.
✍ SI Expert analysis: Underdog's prediction markets have significantly lower fees compared to the traditional sportsbooks' per-bet vig. Taking the time to understand the nuances of trading on Underdog Predicts can lead to substantial long-term gains for anyone well-versed in sports betting.
Markets on Underdog have also expanded from sports to non-sports prediction markets and are now available to accounts through Crypto.com Derivatives North America (CDNA).
- Entertainment: Markets for major awards shows like the Oscars and Grammys.
- Politics and government: Outcomes for presidential elections and specific Senate races.
- Economy and business: Predictions for Fed interest rate decisions and major company milestones.
- Crypto: Speculating on the future price movements of various cryptocurrencies.
The multipliers on Underdog Pick'em adjust based on the player totals you choose for your lineup. As a general rule, larger totals will give you better multipliers when you select "Higher" and lower totals better multipliers when you select "Lower." Always be sure to double-check that you're satisfied with your selection and potential payout before entering.

Underdog promo code FAQ
The current Underdog promo code is SICOM.

The maximum Underdog welcome bonus with the 50% deposit match is $1,000. Because Underdog matches 50% of your qualifying first deposit, you need to deposit $2,000 to receive the full $1,000 bonus.
