Best US Prediction Market Bonuses 2026: Regulated Exchange Offers

Operator Breakdown: Which Prediction Market Bonus Offers the Best Value?

Not all prediction market bonuses are structured the same way. Depending on which of the best US prediction market apps you choose, a welcome offer might come in the form of a deposit match, daily profit boosts, or even reward stock. To help you find the right fit for your specific trading style, I have broken down the exact value and terms of the top prediction market promos below.

1. Polymarket Bonus

Best for: Active traders wanting to place orders and hold positions on multiple markets

Polymarket US gives new users $50 in bonus trading funds for a deposit of $10 or more, five times the deposit in trading credit. The app launched on iOS in December 2025, with Android following in 2026. Deposited cash sits with Polymarket Clearing, the CFTC-licensed clearing organization that holds member funds and settles contracts, while bonus credit stays inside the app. That split is why the $50 is trading credit you cannot withdraw rather than cash.

Here is how the promotion works:

• Polymarket promo code: WSN. Enter it at sign-up when you register through an approved link.

• How to claim: Download the iOS or Android app, create your profile, and clear identity verification with your SSN and a government-issued ID.

• The trigger: Deposit at least $10 via debit card, ACH, Apple Pay, or wire transfer.

• The reward: $50 in bonus trading funds lands automatically once the deposit clears. There are no market-type restrictions, so you can use it on sports, politics, economics, culture, or weather.

• Rollover requirement: A 1x playthrough. The $50 is for trading only and can't be withdrawn to your bank, but cash profits from winning contracts are yours to keep.

2. Kalshi Bonus

Best for: Active traders able to meet the minimum trade

Kalshi was the first federally regulated prediction market in the US, cleared by the Commodity Futures Trading Commission (CFTC) to operate nationwide. It's still one of the strongest prediction market apps around, with deep liquidity, broad market variety, and features like live trading and an ideas forum.

Sign up with the Kalshi promo code WSN and claim the offer: Trade $25 and Get $25

• New users only: sign up through our Kalshi referral link or enter bonus code WSN during registration.

• Verify your account, add funds, and trade at least $25 on Kalshi's Predictions markets within 7 days of signing up (30 days if you registered with the promo code).

• The reward is now a guaranteed match. Once you place your first $25 in trades, Kalshi will drop a flat $25 bonus into your account. You get exactly what is advertised—no more randomized tiers or guessing games.

• Bonus credits only work inside Kalshi's Predictions markets and can't be cashed out on their own. Once you've traded through an amount equal to the credit (a 1x playthrough), any profit becomes withdrawable, subject to the holding period tied to your deposit method.

• Use the credit within 7 days of receiving it. Whatever you don't use expires.

3. Crypto.com Bonus

Best for: Crypto-first traders looking to expand into prediction trading

Crypto.com is a cryptocurrency exchange that also lists event contracts. The prediction market side runs on a CFTC-regulated designated contract market, the same federal framework Kalshi and Polymarket operate under. Because event contract trading is only one part of what the platform offers, there is no specific Crypto.com promo code required for a dedicated prediction market bonus. However, new users can still claim the standard Crypto.com welcome offer and convert the Cronos reward tokens into tradable funds:

• New users get a welcome bonus of Cronos, Crypto.com’s cryptocurrency, after completing a first-month trading mission.

• Requirements vary depending on location but users generally have 30 days to trade a total of $100 or $500.

• Earn the bonus by trading across the platform, not just on prediction markets.

• Hold or trade the CRO or convert it to USD to trade event contracts.

Launched by Crypto.com, OG is a dedicated prediction market offering CFTC-regulated event contracts across sports, politics, economics, and entertainment. Powered by the same Crypto.com derivatives infrastructure that Underdog uses, OG blends institutional grade features with a dynamic social layer where you can share your predictions and climb community leaderboards. Use OG promo code WSN at sign-up to claim the current welcome offer. New users earn $25 in rewards by placing a $25 qualifying trade within their first 7 days on the platform.

Here is a breakdown of the OG welcome offer for new users:

• Sign up for an OG account with promo code WSN

• Place a $25 trade within 7 days of completing identity verification to earn $25 in rewards.

• Only trades placed on contracts with an implied probability of less than 80% count toward the requirement.

• Your qualifying trade must settle within that 7-day window, not just be placed within it.

OG isn't available at all in Arizona or New York. In Nevada, Ohio, Michigan, Maryland, Massachusetts, New Jersey, and Illinois you can't trade sports contracts, but the welcome offer still works on politics, economics, weather, and culture markets.

5. Underdog Predict Bonus

Best for: Existing fantasy players who want prediction markets in the same app.

Instead of launching a separate platform, Underdog integrated its prediction market feature, Underdog Predict, directly into its existing mobile app. Available in over 30 states plus DC, this setup allows users to easily toggle between traditional fantasy contests and peer-to-peer event contracts. The exchange behind it is run by Crypto.com's derivatives arm. Underdog Predict itself is a registered FCM (futures commission merchant), which is the broker that holds your account and passes your orders on to the exchange.

Ready to jump in? Make sure to use Underdog promo code WSNPLAY during sign-up to claim your welcome offer! Here is how it works:

Underdog does not have a separate promotion specifically for their prediction market. Instead, new users simply claim the platform's massive standard welcome offer: Get up to $1,000 in Bonus Cash + a shot at $1,000,000!

• Create your account and remember to use promo code WSNPLAY during sign-up to lock in the bonus.

What Is a Prediction Market Bonus?

A prediction market bonus is a promotional offer designed to welcome new traders or reward active users on an exchange. Because trading event contracts is different from traditional sports betting, these promotions are structured uniquely. Instead of standard bonus bets, you will typically find offers like deposit matches, trade credits, or even free shares in a specific market. The goal of these bonuses is to give you extra flexibility as you learn the platform and test out your trading strategies.

Why There Are No No-Deposit Prediction Market Bonuses

Sportsbook and casino players are used to a no-deposit bonus: free credit before you fund anything. That format doesn't exist on regulated prediction markets, and it isn't an oversight.

Event contracts are financial derivatives, not wagers. Every position on a CFTC-regulated exchange has to be fully funded before it opens, and the money sits with a clearing organization, a separate regulated entity that holds member funds and settles trades between participants. That is the same rule that guarantees you can't lose more than you put in. Credit handed to accounts with no money behind them doesn't fit that structure.These platforms are registered exchanges answering to a federal regulator, so the promotion has to work within the rules of the product.

That's why every offer here attaches to a deposit or a qualifying trade first.

How to Claim & Activate a Prediction Market Bonus Offer

Most prediction market bonuses can be claimed without having to manually enter a promo code. Make sure your new user bonus is applied and keep the key terms and conditions in mind with this step-by-step guide:

1. Use the secure link: Many bonuses don’t need a text-based promo code and a tracking link automatically activates the offer instead. Check our prediction market reviews to see if you need a code or link for your chosen platform.

2. Create an account: Register via the link and create a new account. If you’ve previously registered for a different financial product with the platform, check the T&Cs for eligibility requirements.

3. Verify your identity: Prediction market platforms operate under strict regulation from the CFTC, SEC, or sweepstakes laws. New users must verify their identity and Social Security Number to claim bonuses.

4. Deposit funds: Fund your trading account with your first deposit. Check eligibility requirements: to claim the Robinhood free stock bonus, you must link your bank account via Plaid. If you’re funding your account with cryptocurrencies, check if you need to convert to USD to make trades.

5. Make your first trade: Choose an event and purchase your first contracts. Platforms like Kalshi or Crypto.com require users to trade a minimum amount to receive the bonus.

Where to Use Your Prediction Market Bonus

Bonus credits usually work across a platform's whole market menu, so the question is where to deploy them, not where you're allowed to.

• Sports game markets - Moneyline-equivalent contracts on the night's slate. Deepest liquidity, so you get filled at the price you see.

• Sports futures - Championship, conference, and award markets that settle months out. Good for bonus funds you aren't in a hurry to convert, though your capital is tied up until settlement.

• Multi-leg and player performance contracts - Called different things depending on where you are: player props on Polymarket, Custom Combos on Robinhood, Build Parlay on OG, Multi-team prediction picks on Underdog. Crypto.com has neither. Check what your platform supports before planning a bonus around it.

• Politics - Election and policy outcome contracts, the category prediction markets built their reputation on. Midterm and presidential elections carry the deepest volume of anything outside sports, and confirmation votes and cabinet appointments trade year round.

• Economics and finance - Fed decisions, inflation prints, and jobs numbers. These settle on published data rather than a judgment call, which makes resolution disputes rare.

• Weather - Daily temperature and storm markets on Kalshi and Polymarket. Short settlement windows suit a bonus with an expiry date.

• Culture - Award shows, box office, and music charts. Thinner volume, so expect to wait for a fill.

Are Prediction Market Bonus Winnings Taxable?

Yes. Profit from trading event contracts is reportable income, and it makes no difference whether the money came from your own deposit or from a bonus.

Whether a platform sends you a 1099 is a separate question from whether you owe anything. Operators file forms once your activity clears their reporting threshold, and those thresholds have moved in recent years, but the threshold is the platform's filing obligation, not yours. Income is reportable whether or not paperwork arrives. Coverage is also inconsistent: some operators issue a form covering trading activity, some only cover rewards and referrals, and others issue nothing for contract trading and expect you to export your own history.

The harder question is how event contract profits should be classified, and the IRS hasn't answered it. Gambling income, capital gains, and Section 1256 contract treatment are all defensible readings, and they carry different rates and different rules on whether losing trades can offset winning ones. A platform picking a classification on a form it sends you doesn't settle it either.

Your trade history and any tax documents live in account settings on Polymarket, Kalshi, and Crypto.com. Pull them before year-end rather than reconstructing months of activity in April.

Prediction Markets vs. Regular Sportsbooks

Traditional sportsbooks use bonuses to attract new customers. Bettors often consider the value of sportsbook bonuses when choosing a new betting platform. Prediction market bonuses work a bit differently and operators tend to offer a lower bonus amount, but there’s more to consider when comparing the two:

Sportsbooks:

• Give “Bonus Bets” for placing sports event wagers. These aren’t stake-returned and have no value after use, although winnings may be awarded as cash rather than bonus credits.

• Bets must settle before winnings can be cashed out, unless placing a specific “early cash out” bet.

• Odds are set by the house and include a commission, or vig. A standard -110 line charges 10% on the losing stake, which works out to roughly a 4.5% hold across both sides of the market. Even a boosted-odds promo pays out from a margin that was priced in first.

Prediction Markets:

• May give stocks or cryptocurrencies that have a direct cash value. Bonus cash or credits usually need to be traded or held for a set period before withdrawing.

• Users can sell contracts at any time during an event, instead of waiting for the official outcome to settle.

• Probabilities are set by the market, so users trade peer-to-peer rather than against the house, and the price on screen is the market's forecast of the outcome with no margin priced in. Exchanges charge a separate trading fee instead. Those rates split into two models: Kalshi and Polymarket scale the fee by trade size and by how far the contract sits from 50 cents, while Crypto.com, OG, and Underdog charge a fixed rate. Posting a limit order makes you a maker, which Polymarket and Crypto.com either rebate or waive, and taking a price already on the book makes you a taker at full rate. OG has no limit orders, so every OG trade pays the taker fee.

This is just a short overview of the differences between prediction markets vs. sportsbooks. Simply put, these are two different products for two different audiences.

Responsible Risk Management

Trading event contracts can be entertaining and profitable, but it comes with risks.

Traders should keep bankroll management in mind when signing up for bonuses: don't trade beyond your means just to meet a bonus threshold. Only trade on events you understand, and use the learning resources the platforms publish. Robinhood Learn covers how contract prices are set and how they settle before you put money behind a position.

Event contracts settle on binary Yes/No outcomes, meaning an unsuccessful trade is worth $0 as soon as the event finishes. The trading model means you won’t lose more than you invest, but the value of your contract investments can drop to zero.

The best prediction market apps integrate tools and resources to support traders. Look for a “Responsible Trading” or “Responsible Risk Management” section on the website or app. Trader protection tools include trading breaks, deposit limits, loss limits, mental health support, and self-exclusion options.

WSN is committed to promoting risk awareness and safe trading, and we include responsible risk management in every prediction market review. Beyond prediction markets, you can read about industry-wide player protection in our Responsible Gambling Center, including information on responsible online sports betting.

How We Rate Prediction Market Bonuses

Like any offer reviewed on WSN, we rate prediction market bonuses from direct experience. We test every platform first-hand, personally depositing and claiming offers to verify that they work.

We consider the “rollover” equivalent, determining how easy it is to turn the bonus into withdrawable cash. Prediction markets don’t use standard rollover or playthrough formats, so we look at trading restrictions on bonus funds and how long funds must be held before withdrawal.

We also score what the offer costs to clear. A bonus with a trading volume requirement on a taker-only platform returns less than the same headline figure on an exchange that rebates maker orders, because the fees come off every round trip. Our ratings reflect that rather than the advertised dollar amount.

Transparency is another important factor: we like to see the offer explained clearly up-front, without having to dig through the T&Cs for key details.

Why You Should Trust Us

For over 20 years, WSN has committed to providing our readers with data to make informed decisions on betting and trading. Our team of experts has decades of experience and we’ve covered the evolution of prediction markets from the first US launches to new developments like sweepstakes predictions.

We dig into the regulations and understand the specific laws governing financial exchanges and sweepstakes gaming. When researching and reviewing a platform, we consider the legal framework around it and explain any restrictions or concerns our readers need to know.

Every WSN review is built on factual information and we give our unbiased opinion. We don’t accept payments to change ratings: if a bonus has terrible terms or a site doesn’t meet our standards, we’ll say it straight up.
