Best Prediction Market Bonuses & Promo Codes in the U.S.

Types of Prediction Market Bonuses

The way a prediction market bonus is structured determines how much you can realistically get from it. Before you claim any offer, it helps to know whether you’re getting a no-deposit bonus, a deposit bonus, a trade match, or a multi-step welcome offer.

Trade-Match Bonuses

Trade-match bonuses are built around a simple idea: you trade a qualifying amount, then the platform gives you the same amount back in bonus funds. The result of the qualifying trade usually doesn’t affect whether you receive the bonus, as long as the trade meets the offer terms. Kalshi and Polymarket both offer this type of bonus.

The important part is how those bonus funds work after they hit your account. You usually can’t withdraw them right away, since they need to be used in trades first.

Any profit from trades placed with bonus funds is typically withdrawable as cash. That makes the bonus useful, but it doesn’t make a $10 trade match the same thing as $10 in guaranteed cash.

If you use $10 in bonus funds on a contract priced at $0.50 and it resolves YES, you can end up with $10 in cash winnings.

If you're not familiar with how contract pricing works, here's a full breakdown of how prediction markets work before you dive into bonus math. 

If the same trade resolves NO, the bonus funds are gone. So at even odds, $10 in bonus funds has an expected return closer to $5 before you account for fees or spread.

That’s why it pays to be selective with trade-match bonuses. Save them for markets where you trust your read, rather than burning them on a toss-up just because the promo is available.

No-Deposit Bonuses

No-deposit bonuses give you bonus funds without requiring an upfront deposit or qualifying trade. 

This is the lowest-friction bonus structure because you can start with the promo before putting your own money into the account. The tradeoff is that no-deposit bonuses are usually smaller than deposit-based offers or trade-match promos.

The withdrawal rules can be tighter, too. You typically can’t cash out the bonus funds directly, since they need to be used in eligible trades first.
Profits from trades placed with no-deposit bonus funds are usually withdrawable as cash. That makes this type of promo especially useful for new users who want to test prediction markets without funding the account first.

Deposit-Match Bonuses

Deposit-match bonuses are tied to the amount you add to your account.

The key difference from a trade-match bonus is that the bonus depends on your deposit size, not on the first trade. If the offer is a 20% match up to $100, you’d need to deposit $500 to unlock the full $100 bonus.

That makes deposit-match bonuses a better fit for traders who already planned to fund a larger account. If you were only going to test the platform with a small amount, you may only unlock part of the offer.

Liquidity Rewards Programs

Not every prediction market promo is built for new users. Some rewards are designed for active traders who add liquidity by posting limit orders instead of taking prices already listed in the market.

Kalshi’s liquidity rewards program falls into that category. It gives fee rebates to traders who post limit orders on select high-volume markets, rather than charging the usual maker fees on eligible contracts.

The program applies to select high-volume markets, including NBA, NFL, Fed, and CPI contracts. It’s open to all users, not just new signups, so it can still matter after the welcome bonus window closes.

This is the promo type with the most long-term upside. If you regularly post limit orders in liquid markets, rebates can return a meaningful portion of your trading costs across a full season.

It isn’t signup cash, and it won’t help much if you only place the occasional trade. For active traders, though, it’s worth tracking once the first-time bonus offers are gone.

Referral Bonuses

Referral bonuses are another promo type worth watching, especially if you already know someone who wants to try prediction markets. Most platforms offer bonus funds when you invite a new user, and that person completes a qualifying trade.

Kalshi’s referral program gives both users $10 once the referred friend reaches $100 in total trades. Across prediction market platforms, referral payouts usually fall somewhere between $5 and $25 per completed signup.

The main benefit is that referral bonuses can stack with welcome offers. A new user who signs up through a referral can often claim the standard welcome promo and the referral bonus, as long as both sets of terms are met.

Important T&Cs to Check Before You Claim

Before you claim a prediction market bonus, the fine print is worth a close look. A few rules can change when the bonus is paid, which markets qualify, and how soon winnings can be withdrawn.

• Cash vs. bonus funds: Bonus funds and cash aren’t the same thing. Bonus funds usually need to be used in trades before anything becomes withdrawable. If a bonus-funded trade wins, the payout is typically made in real cash. If it loses, the bonus funds are forfeited.
• Minimum trade to trigger: Most trade-match bonuses require at least $10 in qualifying trade volume before the bonus is awarded. Some offers may only count certain market types, so confirm your preferred markets count before placing the trade.
• Expiry window: Bonus funds usually expire if you don’t use them within the listed window. Many promos use a 30-day deadline, while OG’s step-based bonus funds come with 7-day use windows for each tier.
• Withdrawal conditions: Most platforms require bonus-derived winnings to complete one qualifying trade cycle before withdrawal. Some platforms also set minimum withdrawal amounts, so check the payout rules before assuming you can cash out right away.
• State restrictions: Availability changes by platform. Kalshi isn’t available in Nevada; Polymarket US availability varies, and FanDuel Predicts, OG, Crypto.com, and Novig each have their own state lists. Novig also requires users to be 21+ and excludes 14 states.
• One bonus per household: Platforms usually limit welcome bonuses to one per household, IP address, or device. Using a VPN to get around state restrictions can lead to account suspension and forfeited funds.
• Market type restrictions: Some bonuses can only be used on certain contracts. OG, for example, requires bonus funds to be used on contracts priced under $0.80, so check eligible markets before placing a trade.

How to Evaluate Prediction Market Promos

The best prediction market promo isn’t always the one with the biggest dollar amount. It’s the one with terms you can complete and markets you’re comfortable trading. Here’s what to check before you decide which bonus deserves your first deposit or first trade.

• Terms and conditions: Fewer rules usually make an offer easier to use. OG often has the biggest welcome bonus, but it requires several steps and more than one deadline. Kalshi’s $10 offer is easier to complete because it requires one qualifying trade within 90 days.
• Market pricing: A bonus works better on platforms where active markets have fair entry and exit prices. If buy and sell prices are far apart, part of the promo gets eaten before the event settles. Kalshi and Polymarket usually price major markets more efficiently. OG and ProphetX can be more expensive to trade on smaller markets.
• Promo math: Compare offers by looking at the bonus size, your realistic chance of converting it into cash winnings, and the cost of placing the trade. Prediction Markets Pro can help here, giving you a historical context on markets before you commit bonus funds to a trade.
• Timing: Don’t claim a bonus just because it’s available. A promo with a 7-day deadline can be wasted if you claim it during a slow week with no markets you like.

How Prediction Market Promos Differ from Sportsbook Bonuses

If you’ve claimed sportsbook promos before, prediction market bonuses work differently in a few important ways. The main difference is that prediction market offers usually have fewer betting-style restrictions and give traders more control after the first trade is placed.

• No rollover requirements: Sportsbook promos often come with playthrough requirements, rules that force you to bet through a bonus multiple times before any winnings become withdrawable. Prediction market bonuses usually don’t use that system. In most cases, you place one qualifying trade, unlock the bonus funds, and then use those funds on eligible markets.
• Full payout on winning trades: Sportsbook bonus bets are usually stake-not-returned. If your bonus bet wins, you collect the profit, but the original bonus bet amount doesn’t come back with it. Prediction market bonus funds usually work differently. If you use bonus funds on a contract and it resolves YES, the full payout can typically return as cash, including the amount covered by the bonus.
• No odds restrictions. Sportsbook promos often limit which bets qualify, with rules such as minimum odds of -200 or longer. Prediction market bonuses usually give you more freedom across contract prices. That means you can use bonus funds on a contract priced near $0.95 or take a shot on a longshot priced near $0.10, as long as the market meets the offer terms.
• Early exits: Sportsbook bonus bets usually lock you into the bet until the event ends. Prediction market positions are different because you can often sell before settlement. If the price moves in your favor, you may be able to close the position early and take profit before the outcome is decided. That gives bonus-funded trades more flexibility than a standard sportsbook bonus bet.
• No expiration on the qualifying trade: Sportsbook bonus bets often expire within a few days after they’re credited. Prediction market promos can give you more time to choose the right spot. Kalshi, for example, gives new users 90 days from signup to place the qualifying trade. That longer window helps traders wait for a market they understand instead of forcing a trade just to beat a deadline.

How to Get the Most Out of Prediction Market Promos

Prediction market promos are easier to use when you already know where you want to trade. The goal isn’t just to claim the biggest offer, but to use the bonus funds in markets with fair pricing, enough activity, and terms you can meet.

Use Bonus Funds in Active Markets

Bonus funds are harder to use well in markets where buy and sell prices are far apart. This gap is called the spread, and it's one of the most overlooked costs in prediction market trading. 

If a contract costs $0.55 to buy but only sells for $0.45, you give up part of the promo before the event even starts.

That difference can hurt more than people expect. On a 10-cent spread, a $10 bonus loses buying power right away because you’re entering at a worse price than you could exit for.

The better approach is to use bonus funds in active markets. Major sports outcomes, Fed rate decisions, CPI inflation releases, NBA futures, NFL futures, and high-profile mentions markets usually have more trading activity and better pricing on Kalshi.

Polymarket’s major political markets can be efficient too, especially when both sides have plenty of traders. Be careful with niche markets where the price looks tradable, but there isn’t much order depth behind it.

Use Limit Orders When You Can

A limit order lets you choose the price you’re willing to pay instead of accepting the current market price. When you’re using bonus funds, even a few cents can change the result.

For example, if you use a $10 bonus on contracts priced at $0.50, you’re buying 20 contracts. If a limit order saves you 3 cents per contract, you’ve saved $0.60 before the event begins.

Kalshi and Polymarket both support limit orders, which give traders more control over entry price. OG and FanDuel Predicts don’t offer the same control, so you take the listed market price when you trade.

If you’re using a larger bonus, price control becomes more important. A better entry can leave you with more upside and less pressure to get every call right.

Bonus Trade Arbitrage Across Platforms

If you have bonus funds on two platforms at the same time, you may be able to compare prices on the same event before choosing where to trade. In rare cases, traders can take opposite sides on two platforms and reduce risk.

The basic idea is simple. You might buy YES on one platform and NO on another if the prices create enough room for one side to pay out with a positive result overall. Our arbitrage tool can help you spot these opportunities faster than scanning both platforms manually.

This only works when the math is favorable. Prices move quickly, and fees or poor entry prices can erase the edge before you place both trades.
This approach is usually most realistic on major political markets where Kalshi and Polymarket both have active trading. Check the terms on both platforms first, and run the numbers before committing any funds.

Time Your Sign-Up Around Major Events

Welcome bonuses have the same headline amount no matter when you claim them. The difference is how many good markets are available when your bonus funds need to be used.

Major events usually give traders more options and better pricing. NFL playoffs in January, March Madness in March, NBA Finals in June, Fed decision dates, CPI reports, and the fall election cycle are all stronger windows for prediction market activity.

Try not to claim a short-deadline promo during a quiet part of the calendar. If your bonus expires in 7 days and there aren’t any markets you like, you may end up forcing a trade just to use it.

The smarter move is to claim prediction market promos when you already have markets in mind. That gives you a better chance to use the bonus on a position you would consider anyway, instead of chasing a deadline.

When Prediction Market Promos May Fall Short

Some prediction market promos look better at first glance than they are in practice. Once you account for the rules, eligible markets, deadlines, and trading costs, the offer can be less useful than expected.

Here are the main spots where a prediction market promo can lose some of its appeal.

• Bonus funds aren’t cash: A $20 trade-match isn’t the same as $20 in guaranteed money. If you place the required trade, receive the bonus, and then lose the bonus-funded trade, the bonus funds are gone. You may also lose the money used for the qualifying trade. In that case, you’re down your original trade amount, not ahead because the promo was claimed.
• Weak market pricing can reduce the bonus: On platforms with less active trading, buy and sell prices can be far apart. If you use a $10 bonus at the listed market price, the position may be worth closer to $8 or $9 if you try to sell it right away. Check pricing before choosing which platform bonus to claim first. A smaller bonus on a busier market can beat a larger bonus on a market where entry and exit prices work against you.
• Expiration deadlines can push bad trades: Bonus funds often expire, which can pressure traders into markets they wouldn’t normally play. A rushed trade in a market you don’t understand can cost more than the promo is worth. OG’s 7-day use windows are the tightest on this list. If you claim that offer, make sure you have eligible markets in mind before the clock starts.
• State restrictions can change: Platform availability can shift after sign-up. If a platform stops operating in your state, you may lose the ability to place trades or use remaining bonus funds with limited warning. This is especially important in the U.S., where prediction market rules continue to develop across states. Confirm your eligibility before signing up, and keep an eye on platform notices after you register.
• Small bonuses won’t fix bad trading: A $10 bonus won’t make up for consistent losses if you’re trading markets without a real edge. Promos can improve the math around the margins, but they don’t turn random trades into good ones. Use prediction market bonuses as a boost to trades you already like, not as a reason to force action.
