The $25 SIBONUS offer is worth 2.5x your initial deposit and is currently the largest active welcome bonus you can claim on Polymarket U.S. for November 5, 2026. No first trade is required to unlock the offer, and your credits arrive once your deposit clears.

We'll show you how to claim the $25 Polymarket welcome bonus, explain the offer requirements, and highlight how to use your bonus on NFL Week 9 prediction markets.

The Polymarket promo code SIBONUS gives eligible new Polymarket US customers $25 in trading credits after a minimum $10 deposit, with no qualifying trade required. This is currently the largest active welcome offer we're tracking on Polymarket. The promotion is for new users only in eligible states, excluding Arizona, Illinois, Maryland, Massachusetts, Michigan, Montana, New Jersey, Nevada, and Ohio.

Once your qualifying deposit settles, the $25 bonus will be credited to your account, giving you $35 in total starting trading funds ($10 deposit + $25 bonus). Any profits you receive from trades made with your bonus funds on Polymarket will be yours to keep and eligible for withdrawal; however, you cannot withdraw the trading bonus as cash and must use it for trading.

Looking for the $50 Polymarket offer? It ended on Oct. 1, 2026. The current welcome bonus is $25.

Polymarket US platform availability, sports-contract availability, and welcome-bonus eligibility are separate. Users may be able to access Polymarket without qualifying for the SIBONUS promotion. Confirm the bonus eligibility displayed during registration before depositing.

We tested the Polymarket welcome bonus ourselves and confirmed that you'll receive a $25 trading bonus when you sign up with the active promo code SIBONUS and make a qualifying deposit. In our eyes, this is one of the top prediction market promos you can claim today.

The $25 welcome offer works from sign-up through receiving and using the bonus. Geoff Ulrich and I each created an account, completed KYC, deposited at least $10, and successfully received the $25 in trading credits.

How does the Polymarket promo code work? 

In our tests, KYC took only a few minutes, and our deposits were processed immediately, exactly what you would expect from one of the top-rated prediction market apps. The $25 credits became available after our qualifying deposits settled, and neither of us had to complete a qualifying trade to unlock the bonus.

The biggest advantage we found is that Polymarket doesn't require you to complete a qualifying trade to get the free $25. This means the Polymarket $25 offer has similar overall terms to the Polymarket free $50 offer, which is no longer available but also had no qualifying trade requirement.

✅ Our test result: Both testers successfully received the advertised $25 in trading credits by using the best Polymarket promo code SIBONUS.

✍️ Our takeaway: Both of our tests produced the same result: deposit at least $10 and receive $25 in trading credits after the qualifying deposit settles, equivalent to a 250% deposit bonus.

Our tests required no qualifying trade to unlock the bonus and had no unexpected extra steps.

Enter the Polymarket invite code SIBONUS during account registration to qualify for the current $25 new-user bonus. Start by opening Polymarket through a verified promotional link, create your account, and enter SIBONUS when prompted during sign-up.

After verifying your account, deposit at least $10. There is no qualifying trade requirement, and the $25 in trading credits is added after your eligible deposit settles.

A few things to know when using a Polymarket invite code:

• ✅ You no longer need an invitation to join Polymarket. Eligible U.S. users can create an account without joining the previous waitlist.
• ✅ An invite or promo code is different from your personal referral code. SIBONUS unlocks the largest active new-user welcome bonus, while your personal Polymarket referral code can be shared with friends after you join.
• ✅ Enter SIBONUS during registration. Use a verified promotional link and make sure the code is attached to your account before completing registration.
• ✅ The offer is available through the Polymarket US app for eligible users who register through a qualifying promotional campaign and satisfy the offer terms.

Is the Polymarket app available on iPhone and Android?

Yes. The regulated Polymarket US app is available to eligible users on iPhone (iOS) and Android, allowing users to trade prediction markets directly from their mobile devices.

Polymarket is also no longer invite-only, so eligible U.S. users can register without joining the waitlist that was used during the platform's earlier rollout.

Once your account is active, you can access eligible prediction markets for sports, including Polymarket NFL markets, and other real-world events on the Polymarket US platform.

After you claim the $25 Polymarket bonus with promo code SIBONUS, you can use your trading credits on eligible prediction markets on one of the best NFL prediction market apps. Polymarket offers markets covering game winners, spreads, totals, player props, touchdowns, and other outcomes throughout the NFL season.

🏈 NFL Week 9 prediction markets on Polymarket — November 3

NFL Week 9 kicks off Thursday, Nov. 5, with the Jacksonville Jaguars visiting the Baltimore Ravens at 8:15 PM ET on Prime Video. Jacksonville enters at 5-2, while Baltimore sits at 4-4, setting up an AFC matchup to open the week.

Polymarket offers game-winner, spread, total, and player outcome markets across the NFL. Jacksonville is a heavy favorite Thursday at approximately 80¢ to win, compared with 21¢ for Baltimore. The Jaguars are also favored by 8.5 points, with a game total of 42.5 points.

Here are the latest approximate Polymarket prices for Thursday Night Football:

Jacksonville carries an implied win probability of approximately 80%, making the Jaguars one of the strongest favorites entering Week 9. However, their -8.5 spread contract trades closer to 51¢, indicating a more evenly priced market on whether Jacksonville wins by at least nine points. The 42.5-point total is similarly balanced, with Over and Under contracts trading around 50¢ and 51¢, respectively.

Example bonus trade: If you used $10 in eligible Polymarket trading credits to buy Ravens game-winner contracts at approximately 21¢, you could purchase 47 contracts for $9.87 before fees. If Baltimore wins, those contracts settle for $47, producing a $37.13 gain before fees. If Jacksonville wins, the contracts settle for $0. Withdrawable proceeds and use of promotional credits depend on the applicable bonus terms.

Updated Nov. 3, 2026. Prices are approximate Polymarket US quotes and can change before kickoff.

Polymarket US is available in most states, but access to the platform, sports markets, and the $25 SIBONUS welcome bonus can vary by location. New users in eligible states can deposit $10 and receive $25 in trading credits with promo code SIBONUS.

The table below shows where Polymarket US is available, which states allow sports event contracts, and where new customers can claim the $25 bonus.

Checked against Polymarket's promo terms on Nov. 5, 2026.

The $25 SIBONUS welcome bonus is unavailable in Arizona, Illinois, Maryland, Massachusetts, Michigan, Montana, New Jersey, Nevada, and Ohio. Michigan users cannot open new sports event contracts, while Polymarket US is unavailable in Nevada. Platform access does not automatically guarantee eligibility for the welcome offer.

You can get started with the Polymarket promo code SIBONUS first-time bonus offer today by following four simple steps:

1. Open the Polymarket offer

Start by opening Polymarket through one of the verified offer links on this page and selecting Sign Up to create your account.

Make sure you're using the correct offer before registering, since the SIBONUS promo code offers the largest bonus award of $25. None of the other codes we found offer more. It must be entered during registration and cannot be added retroactively after your account has been created.

2. Register and enter promo code SIBONUS

Create your new Polymarket account and enter the Polymarket promo code SIBONUS when prompted during registration.

Have your basic personal information ready, including your date of birth, phone number, email address, and current address. You may also need to confirm your email as part of the registration process.

3. Verify your identity

Complete Polymarket's required identity-verification process. You'll need to successfully verify your account before you can fund it and access the welcome offer.

Follow the prompts in the Polymarket app and provide any requested information or documentation to complete verification.

4. Deposit $10 and receive $25 in bonus credits

Make a qualifying deposit of $10 or more into your verified Polymarket account. Once you've met the deposit requirement, you'll receive $25 in Polymarket trading credits with no qualifying first trade required.

That means you can use the $25 bonus credits toward your first eligible trade, rather than placing a separate real-money trade to unlock the offer.

Polymarket US supports several funding methods, including debit card, ACH bank transfer, Apple Pay, and eligible crypto funding options.

💡 Important: The $25 bonus is issued as trading credits rather than withdrawable cash. However, eligible profits earned from trades made with the credits can be withdrawn subject to Polymarket's terms.

Yes, Polymarket US is a legal, federally regulated prediction market platform for eligible U.S. users. Polymarket operates under Commodity Futures Trading Commission (CFTC) oversight as a Designated Contract Market (DCM), allowing it to offer regulated event contracts on sports and other real-world outcomes.

Unlike a traditional sportsbook, Polymarket lets users buy and sell event contracts based on the probability of an outcome rather than place fixed-odds bets against a sportsbook.

Is Polymarket regulated by the CFTC?

Yes. Polymarket US operates as a CFTC-regulated prediction market, with its U.S. exchange operating under a Designated Contract Market (DCM) designation.

This federal regulatory framework allows Polymarket to offer eligible event contracts in the U.S. and distinguishes the platform from traditional online sportsbooks, which are generally licensed and regulated at the state level.

Is Polymarket a sportsbook?

No, Polymarket is a prediction market, not a traditional sportsbook. Instead of placing a fixed-odds bet against a sportsbook, users buy and sell contracts based on whether an event will happen.

Polymarket contracts are generally priced between $0.01 and $1, with the price reflecting the market's implied probability of an outcome. A winning contract settles at $1, while a losing contract settles at $0.

For sports users, the experience can look similar to sports betting because Polymarket offers markets on NFL games and other sporting events, but the underlying trading and regulatory structure is different.

Can I use Polymarket in states without legal sports betting?

Yes, eligible users can access Polymarket US sports prediction markets in states where online sports betting isn't legal, including California. Unlike traditional sportsbooks, Polymarket US offers event contracts through a federally regulated exchange, although state restrictions and legal challenges can affect availability.

With California sports betting and Texas sports betting still unavailable through licensed online sportsbooks, prediction market platforms such as Polymarket and Kalshi provide eligible residents with another way to trade on NFL, NBA, MLB and other sporting events.

For readers exploring Georgia sports betting alternatives, Polymarket US also offers eligible users access to Atlanta Falcons NFL markets and other sports predictions. New customers can use the SIBONUS Polymarket promo code to deposit $10 and receive $25 in trading credits, subject to eligibility and promotional terms.

In Florida, where Florida sports betting is available through a limited sportsbook market, Polymarket US provides another option for eligible traders. Users can explore football, basketball and other sports contracts without placing traditional sportsbook wagers.

Polymarket is also among the New York prediction markets available, giving eligible residents access to sports event contracts alongside the state's established legal sportsbook market.

State restrictions still apply. Polymarket US no longer allows new sports-related trades in Michigan following an agreement announced on approximately October 27. Traders must close existing Michigan sports positions by November 25. Other restrictions affect states including Arizona, Illinois, Maryland, Massachusetts, Montana, Nevada, New Jersey, and Ohio, so traders should confirm their eligibility and available markets before depositing.

While Polymarket US operates within a federal regulatory framework, its sports contracts face ongoing legal challenges in several states. Availability can change following court decisions or regulatory actions.

Polymarket is a prediction market platform and one of the best NBA prediction market apps, where you can trade event contracts cleared and settled on a regulated U.S. exchange in USD. In short, Polymarket is an exchange that lets users speculate on the outcomes of real-world events using USD and simple 'Yes' or 'No' contracts. Each contract is priced between $0 and $1, reflecting the market’s perceived probability that an event will occur.

If your prediction is correct, the contract settles at $1; if not, it settles at $0. On Polymarket, you can trade on regular game outcomes, but there is also high liquidity on futures and specialty markets such as who will be the NFL Champion in 2027.

Like most prediction markets, prices on Polymarket are driven entirely by user activity, so markets move in real time as new information and opinions develop. Instead of fixed odds, you’re buying and selling positions based on probability, with no traditional sportsbook vig attached and low trading fees, allowing you to keep more of your profits.

Polymarket Combos

In addition to lower fees and the largest liquidity and trading offerings in prediction markets, Polymarket offers one of the most advanced Combo Builders in the industry.

Users can now build up to 32-leg combos, including same-game parlays on eligible sporting events, while combining moneylines, spreads, totals, and player props into a single position. During our testing, the Polymarket combo builder was fast, intuitive, and updated projected payouts in real time as selections were added. Backed by some of the deepest liquidity in prediction markets, Polymarket is one of the top prediction market combo platforms and a trading app anyone interested in parlay or combo trading should check out today.

The Polymarket referral program is for existing users who can get a $25 credit per eligible referral, up to 50 referrals ($1,250 max). This page focuses on the separate SIBONUS $25 welcome offer for new Polymarket users.

However, the Polymarket referral program is separate from the Polymarket promo code SIBONUS and its $25 new-user welcome bonus.

We break down the differences below:

Can existing users get the Polymarket $25 promo code?

No, the SIBONUS $25 welcome offer is for eligible new users. Existing Polymarket users cannot use SIBONUS to claim another $25 welcome bonus, but they may be able to earn referral credits by inviting new users through Polymarket's separate refer-a-friend program.

The Polymarket promo code that includes a $25 trading bonus is one of our top welcome offers for prediction market traders. However, several platforms offer event-based trading, with unique welcome bonuses that new users can capitalize on. 

Use our summary of how the Polymarket sign-up bonus compares to promos at other leading prediction market sites. 

Polymarket vs. Kalshi

The Kalshi promo code VIP60 offers users a simple $60 bonus. You'll receive your bonus after making $25 worth of trades, and you'll get access to a top trading app. Other apps like Kalshi or Polymarket offer similar sign-up bonuses.

Additionally, you can take advantage of the Kalshi referral code and earn up to $1,000 in bonuses by getting $25 per referral.

Polymarket vs. ProphetX

The ProphetX promo code is another strong option for sports-focused prediction market traders, offering a $40 bonus after you settle $40 in trades. Polymarket has broader name recognition and a larger overall selection of markets, but ProphetX may be a better fit for users who want a straightforward sports trading promo with a low entry requirement.

Polymarket vs. OG.com

The OG promo code caters more to sports-focused traders who enjoy social and community features, as well as prediction markets. Polymarket offers a better overall platform for experienced traders, and the Polymarket promo is also easier to claim. 

Polymarket vs. Underdog

The Underdog promo code offers far more upside, with a 50% first-deposit match worth up to $1,000 in bonus entries or the play $10, get $50 offer.

Polymarket vs. FanDuel Predicts

The FanDuel Predicts promo code gives users $100 in bonuses after trading $1 a day for five days. Each day gives you a $20 bonus. It takes longer to get the full bonus in comparison to Polymarket.

Polymarket vs. Crypto.com

The Crypto.com referral code will give you access to a welcome offer and a referral program that offers big rewards for active traders. However, the Polymarket referral code gets you access to a much simpler option and is better suited to beginner traders and those who want to focus on sports. 

Polymarket vs. Novig

If you compare the two in terms of value, the Novig promo code offers a bigger bonus. Polymarket also offers a much broader selection of prediction markets beyond sports, which may appeal to users interested in trading on politics, economics, entertainment, and other events.

Polymarket vs. Plus500

The Plus500 promo code gives new users a $20 bonus after they complete at least $10 in qualifying Prediction Market trades and those contracts settle. Polymarket offers a larger welcome bonus, while Plus500 has a lower trading requirement, making it a good alternative for users who want to qualify for their bonus with less trading activity.

Polymarket vs. Gemini Predictions

The Gemini Predictions promo code lets users get up to $100 in Predict Cash through a 50% deposit match.

Polymarket vs. Onyx Predictions

The Onyx Predictions promo code offers a $50 bonus after $10 in qualifying trading activity. That's double Polymarket's $25 welcome bonus, although Polymarket only requires a $10 deposit to unlock its offer.

Polymarket vs. other prediction sites

If you're interested in a sports exchange where you can determine your own odds, take a look at our apps like Novig page for further details. Alternatively, if you're used to trading stocks and financials and are looking to expand your trading selection, our apps like Robinhood prediction market page has you covered.

NFL Week 9 kicks off Thursday, Nov. 5, with the Jacksonville Jaguars visiting the Baltimore Ravens at 8:15 PM ET. Polymarket US offers additional NFL markets beyond game-winner contracts, including spreads, totals, player props, touchdown outcomes, and other game-specific predictions.

The featured matchup is Jaguars vs. Ravens, with Jacksonville favored at about 81¢ to win versus 20¢ for Baltimore. The Jaguars enter at 5-2, while the Ravens are 4-4. Jacksonville is also favored by 9.5 points, with the game total set at 42.5.

🏀NBA: NBA Champion 2027

The Oklahoma City Thunder have dropped to a clear second place after the Jalen Williams injury. The Spurs are now the lone favorite on Polymarket to win the 2027 NBA Championship.

Polymarket probabilities updated as of 10:15 AM ET on Nov. 3, 2026.

Polymarket operates differently from a traditional sportsbook. Costs are not embedded in the odds, and many market categories are completely free to trade. Understanding the fee structure, funding options, and withdrawal process will help you get the most out of the platform.

💸 Polymarket US trading fees

Polymarket US charges trading fees on taker orders, with the amount determined by the number of contracts traded and their current price. Unlike the international Polymarket platform, the Polymarket CFTC-regulated U.S. exchange uses a standard probability-based fee formula rather than separate percentage rates for sports, politics, crypto, and other market categories.

Taker fees are highest when contracts trade near 50¢, where the outcome is most uncertain, and decrease as prices approach 1¢ or 99¢. Standard taker fees use a coefficient of 0.0695, effective October 7, 2026.

Here's what Polymarket US charges for an immediate purchase of 100 standard contracts at different prices:

Maker orders that add liquidity to the order book do not incur standard trading fees. Eligible filled maker orders can also earn rebates, although Polymarket US is introducing significant changes to its rebate program.

Starting October 19, 2026, maker and taker rebates will depend on monthly trading volume. Maker rebates will only be available to traders with at least $10 million in qualifying monthly maker volume, while taker rebates will begin at $250,000 in monthly taker volume.

Polymarket US also has separate fee calculations for combination contracts and table tennis markets. For example, purchasing 100 standard contracts at 50¢ costs $1.74 in taker fees, compared with approximately $1.92 for 100 combo contracts at the same price.

Deposits and withdrawals: Polymarket US does not list standard fees for supported deposit and withdrawal methods, though third-party payment providers or banks may charge their own fees.

📊 Trading limits

Deposit methods, including debit card, Apple Pay, and bank transfer, carry a $50,000 daily maximum. Individual market liquidity varies across the platform, and thinner markets can produce faster price movements and less predictable order fills. Checking market depth before placing larger trades is worth the extra step.

💳 Polymarket US payment methods

Polymarket US lets eligible users fund their accounts directly in U.S. dollars. Current funding options include debit cards, ACH bank transfers, Apple Pay, and wire transfers, although availability and processing times can vary by payment method. 

Funding options on Polymarket US can vary from those on the international Polymarket.com platform, which supports crypto deposits. U.S. users should follow the payment options displayed in the regulated Polymarket US app.

For the SIBONUS $25 welcome offer, eligible new users need to deposit at least $10 to qualify.

Polymarket is near the top of our prediction markets for payouts list.

Is there a Polymarket promo code with no deposit?

No. The current Polymarket $25 promo code SIBONUS requires a minimum $10 qualifying deposit, so you cannot claim the $25 welcome bonus without depositing.

However, you don't need to make a qualifying trade to activate the bonus. Once an eligible new user signs up with SIBONUS and the $10+ qualifying deposit settles, Polymarket issues the $25 bonus as trading credits.

💸 Withdrawals

Withdrawing funds from Polymarket US is straightforward. Simply open your account, select Withdraw, enter your linked banking details, and confirm the transaction. Any funds tied to open positions remain unavailable until those contracts are sold or officially settle.

Once a market resolves, winning contracts are automatically credited to your U.S. dollar cash balance, which can then be withdrawn directly to your linked bank account using one of the supported withdrawal methods.

Polymarket offers a unique alternative to other prediction apps and apps like Betr, combining real-time event trading with a clean, intuitive interface. The $25 Polymarket trading bonus is a strong entry point for new users, but the real appeal lies in the platform’s fast-moving markets, deep event selection, and transparent contract pricing.

⭐ Market variety 4.9/5: Polymarket has one of the broadest market menus in the prediction trading space, period. They cover sports, politics, crypto, finance, entertainment, pop culture, and major global news. From a user perspective, this is where Polymarket stands out most, as you can trade event contracts on anything from lacrosse to the number of Elon Musk tweets between a specific date.

⭐ Market liquidity 4.8/5: Polymarket’s size gives it a major advantage, with many popular markets offering strong liquidity and tight pricing. In my experience, the biggest sports events such as the World Cup, elections, and news markets are usually easy to enter and exit without much friction. Polymarket's World Cup Winner market surpassed $4B in trading volume by the end of the tournament.

⭐ Resolution reliability 4.8/5: Polymarket makes sure that markets are clearly structured, with visible rules and settlement criteria listed before you trade. That transparency makes it easier for new users to understand what needs to happen for a contract to resolve as “Yes” or “No.” While outcome resolution on some obscure markets can still be confusing, Polymarket does a great job, overall, at ensuring resolution criteria is reliable and well-stated. 

⭐ User experience 4.7/5: The mobile-first design is clean and responsive, making it easy to browse markets, place trades, and track positions without friction. Polymarket US also now offers desktop web access in addition to its mobile apps, with its web platform rolling out in beta in September 2026. I also found the account setup and deposit flow simple, with fiat deposit options such as PayPal and debit cards converting instantly into usable trading funds inside the account.

⭐ Fees and limits 4.6/5: Polymarket’s pricing model is straightforward because you buy and sell event contracts rather than place traditional sportsbook bets. The main thing to watch is market price movement, liquidity, and any trading costs that may apply when entering or exiting positions.

⭐ Banking, deposits, and withdrawals 4.8/5: Deposits are quick and straightforward. In my experience, funding my account in USD was simple, and funds were deposited instantly. Withdrawals are generally smooth, though timing can vary depending on market settlement and the withdrawal method used.

⭐ Bonuses and promotions 4.9/5: The Polymarket promo code SIBONUS gives new users a $25 trading bonus, which they can claim after depositing $10 or more. Compared with some prediction market promos, the Polymarket code offers one of the better bonus values, since the free $25 credits require only a small deposit.

✍️ Overall Rating (SI Verdict): 4.8/5: Polymarket continues to set the standard for prediction market apps. After using the platform, I found it easy to fund an account, navigate between markets, and execute trades with minimal friction. The resolution terms on niche markets, such as the short-term price of BTC, were well displayed. Overall, Polymarket offers one of the most polished and active prediction trading experiences available today.
