Underdog Fantasy promo code explained

Claiming the Underdog promo code is simple, with only a handful of easy steps. 

1. Register as a new user on Underdog.
2. Deposit $10 on the site.
3. Complete a $5 entry on the Underdog Fantasy app.
4. Receive $50 in bonus entry credits.

After completing these steps, you'll be able to use your $50 in bonus entries as a substitute for cash when entering contests across Underdog Predictions, Fantasy, and Pick'em. 

🐶 Important information about Underdog bonus funds:

While the Underdog bonus credits can be used across the site, they are not cash, non-withdrawable, and come with a few other important features:

• Bonus entries from the Underdog welcome offer come with a 14-day expiry date.
• You won't receive your stake back on any entry made using Underdog bonus credits.
• Underdog bonuses are non-withdrawable and not usable outside the app.

I'll explain in greater detail exactly how I unlocked the Underdog promo code, citing specific examples of how I completed each step and used my bonus funds to secure even more profit. 

This is my step-by-step guide to claiming the Underdog Fantasy Promo code: 

1. Sign up for Underdog Fantasy

First, download the Underdog Fantasy app using one of the links on this page. Then register a new account.

Afterward, provide all personal details to complete the verification process. Ensure you have a driver's license (or other identification) and banking information at the ready. 

2. Deposit and unlock the bonus

Your next step involves depositing. You'll only need $5 to complete the entry portion of the Underdog promo code, but you will still need to deposit at least $10 to unlock the bonus. Underdog has a ton of great contest options, including Underdog Predict, so you may even want to deposit more at startup. 

Underdog accepts Visa, Mastercard, Amex, Discover, PayPal, and Bank transfers. All trustworthy options. I used PayPal for my initial deposit and continue to use it for withdrawals. I find it's a great all-in-one stop.  

3. Enter Pick’em or draft contests on Underdog

Once you've set your account up with some funds, a simple $5 entry into any Underdog contest will free up $50 in bonus entries. Depending on what state you live in, you'll get to choose from a handful of different Underdog fantasy contests, including Best Ball, Daily Drafts (Battle Royale), and Pick'em (Higher/Lower and Rivals). 

As a sports better and trader, I used a $5 Pick'em entry to complete my bonus. Higher/Lower Pick'em works similarly to how parlays on regular sportsbooks work, and requires you to put together two or more picks on the same card. One $5 entry in Pick'em and I was set.

4. Use bonus funds and withdraw winnings

After my Pick'em entry settled the $50 in bonus credits hit my account. You'll get the $50 win or lose, so don't worry about the result of that first entry. 

You're free to use the $50 in bonus entries however you like, and can break them into smaller increments. I mainly used my credits on more Pick'em entries and a few small Underdog Best Ball entries. Withdrawing afterward is simple, and most users will have access to the following options:

• Debit card
• Online banking
• PayPal
• Venmo

Online banking transfers are generally instant, but if you don't want to set up your account information on site, I suggest PayPal or Venmo.

The Underdog bonus functions as a separate balance in your account, often referred to as "Bonus Cash" or "Promo Credits," and can be used as a substitute for cash when entering contests. You can use your Underdog bonus credits to enter a contest of any size as long as you have the necessary amount available. 

Other important terms to understand when claiming the Underdog bonus include:

• Playthrough requirements: You'll need to play $50 in entries on the Underdog app, meaning there is a 1x playthrough requirement.
• Expiry limits: 14-day expiry window, longer than the standard seven-day window on bonus bets at traditional sportsbooks.
• Contest restrictions: The bonus can be used on anything you like in the Underdog app, including Underdog Predict. Certain contests, such as Underdog Pick'Em and Best Ball, have more limited availability by state.
• Withdrawal conditions: Underdog bonus credits cannot be withdrawn or used anywhere other than the Underdog app. However, cash won from entries using bonus credits will be available for withdrawal immediately.

After unlocking the $50 bonus on Underdog with a $5 Pick'em entry, I used my entry credits across the Underdog app to play Pick'em, increasing my profit.

Here's how I did it. 

I was pretty aggressive with my $50 Underdog bonus, choosing to play in just four contests. I could have easily lost all four entries, but since I had to invest so little to unlock the bonus, I decided to swing for the fences. 

Hitting just one of the three-leg Pick'em lineups I entered allowed me to get back more than the actual bonus amount in cash, and I was also lucky to nail another smaller payout on a two-leg play.

End result:

• $50 in bonus credits
• Four Pick'em entries
• +$97.5 in cash (no stake returned on using bonus)

I ended up withdrawing a little afterward, but as a fantasy football fan, I also spread the profit across some entries in Underdog's NFL Best Ball contests. Underdog's best ball game remains my top choice for season-long drafting. 

This is how the current Underdog promo code compares when up against top social platforms that offer prediction trading and new-user bonuses in May 2026.

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:

Predictions markets are exploding across the U.S., with platforms like Kalshi and Polymarket now considered top-rated and wildly popular speculating sites. Underdog has also entered the prediction space with the launch of Underdog Predict in 2025, which is available on the Underdog app across most of the U.S. 

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. With predictions, all prices are dynamic and update in real-time as trading occurs. 

Key features on Underdog Predicts

Real-time trading: Prices per contract range between $0.01 and $1.00 with no set price as you'd see on standard sportsbook odds. 

Wide range of sports to trade: Options to trade on include major sports, leagues, and non-sports markets such as entertainment award shows, such as: Football, Basketball, Baseball, Hockey, Tennis, college football, Soccer (World Cup), Weather, Politics, and Economics. 

Easily accessible: Underdog Predict is available within the Underdog Sports app, so you can rotate between games and move your bankroll around with ease.

How to trade on Underdog Predict

Accessing Underdog Predict is simple. As an existing Underdog user in a supported region, you'll have immediate access to Underdog Predict on the Underdog app. 

Once you've downloaded and signed up with Underdog, just follow these steps to start trading. 

1. Open the Underdog app and go the Underdog home screen. 
2. Look for the 'Team Picks' tab. This is where you'll find Underdog Predict and begin trading.
3. Once in Predictions, select a game to view all of the outcomes available to trade on for that event.
4. Select a trade, set the number of contracts you wish to purchase, and then lock in your trade.

Key terms for Underdog Predict

Event contract: A tradable contract priced from $0.01 to $1, representing either a "yes" or "no" position on a specific event, such as whether a team wins or a player hits a certain stat.

Prediction picks: The main feature allows users to predict outcomes — such as game winners, point spreads, and totals — instead of drafting players, typically for sports like the NFL, MLB, and UFC.

Probability-based pricing: Before an outcome settles, contracts are priced between $0.01 and $0.99 based on the market's implied probability rather than traditional odds. For example, a 65% chance to win results in a price of $0.65 for a "Yes" contract.

Payout/settlement: Correct predictions pay out exactly $1.00 per contract, while incorrect predictions return nothing. For example, buying 10 contracts and having your outcome settle correctly would see a $10 total payout.

Parlay: Parlays on Underdog Predicts are user-requested trades that combine multiple specified events. You can create "parlays" for predictions by combining up to 4 prediction picks into a single entry.

Combo entries: You can also create "Combos," which combine 1 Prediction Pick with 2 to 8 additional Fantasy picks

Game-Level outcomes: These trades are similar to moneylines, spreads, or game totals on sportsbooks. They involve trading a team-specific outcome.

Individual player markets: Contracts based on specific player statistics, such as touchdowns, passing yards, or rushing yards. Similar top player props on sportsbooks.

Exchange/CDNA: The underlying, regulated exchange (Crypto.com | Derivatives North America) that handles the trading and settlement of the contracts.

Cash out: The ability to settle a contract early before the event is finished. Underdog Predicts allows traders to settle a trade at any time before settlement, provided there is sufficient liquidity.

Does Underdog Predict have a welcome bonus?

No, Underdog Predict currently does not offer a specific welcome bonus for new users.

However, because the Underdog prediction platform is integrated into the larger Underdog Sports app, any new user will still be able to access the offer. Even better, you'll be able to access predictions after you claim the offer and use your bonus across the app, however you see fit. 

Underdog Predict markets

Underdog Predict is a new platform, but it already offers a strong selection of markets for traders, with a heavy sports emphasis. I created a current list for all major sports and leagues that Underdog Predict covers, as well as non-sports options such as elections and awards shows:

• Football (NFL)
• Basketball (NBA)
• Baseball (MLB)
• Hockey (NHL)
• Tennis
• College football
• Soccer (World Cup)
• Weather
• Oscars
• Grammys
• Politics
• Economy and business

Where is Underdog Predict available?

Underdog Predict is available in 30+ states, including DC. One note: all users must be 18+ to access predictions.  

If you're big into predictions and want to try an alternative to Underdog Predict or access another platform where you can hedge trades or look for alternative predictions markets, I've laid out your best options. 

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 (4.8/5) 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.

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 4.8/5 rating on the App Store, based on more than 304,000 ratings. 

🤖 Underdog Android app

The Underdog Sports app has a strong rating in the Google Play store as well. With over 29,000 ratings its maintained a strong 4.6/5 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.  

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 (e.g., 2026 World Cup), 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.

Underdog operates as a legal daily fantasy sports (DFS) and regulated derivatives platform in over 40 U.S. states. Availability is divided into three distinct product tiers based on local state regulations.

Pick’em and predictions: Active in 30+ states, including high-traffic areas like Texas,  California, and Florida.

Pick'em Champions: In states like Florida, Alabama, and Arizona, you can compete in Pick'em but only against other users in a peer-to-peer format to satisfy local skill-game laws.

Best ball and daily drafts: Widely available across the U.S. and Canada (excluding Ontario). In states like New York, Maryland, and Ohio, traditional Pick'em is restricted, but you can still enter real-money season-long or daily drafts.

May 3, 2026: Underdog expanded its "Team Picks" offerings for the NBA and NHL postseasons, allowing users to trade on point spreads and moneylines via its regulated prediction market framework, while maintaining its traditional player-prop focus.

March 2, 2026: CEO Jeremy Levine confirmed a major workforce reduction of 125 employees (approximately 20% of staff) as part of a strategic transition from a state-by-state fantasy framework to a national prediction market platform.

Jan. 15, 2026: Underdog became the presenting sponsor of the 2026 Shrine Bowl Analytics Competition, a partnership with SumerSports designed to provide participants with access to real-world football data for NFL-level scouting and analysis.

• PrizePicks: Is often considered the most user-friendly for beginners due to its "Flex Play" (payouts even if you miss one pick).
• DraftKings Pick6: Unique because you compete against other users rather than the house, which can be easier or harder depending on the field.
• Sleeper Fantasy: Currently offers the largest total dollar amount for their welcome bonus, making it great for high-volume players.
