Best Prediction Market Promos in July 2026

✅​ Prediction Market Promo Codes last verified on July 15, 2026

1. Polymarket: Highest Value Welcome Offer

Polymarket asks for more upfront than the smaller trade-triggered offers on this page, but it also gives the largest trading credit. With promo code ACTION, new users can deposit $20 and get a $50 trading bonus once that first deposit clears.

This is trading credit, not withdrawable cash. You can use the $50 on eligible prediction markets, and any eligible profits from those bonus-funded trades can be withdrawn after settlement.

After claiming the welcome offer, you can take advantage of the app’s existing-user promos:

• Liquidity Rewards: Polymarket rewards users who add liquidity to the books. In simple terms, if you place limit orders on certain markets, you can earn extra cash. How much you get depends on things like the price you set and how long your order stays open.
• Refer-a-Friend: After you’ve traded $10,000 total, you can invite friends and earn a cut of their fees. 10% from people you refer directly and 5% from people they refer. You’ll earn these rewards for up to 30 days, or until your referral reaches Platinum status.

2. FanDuel Predicts: Most Simple to Claim

FanDuel Predicts doesn't ask for a promo code for this offer. New users can claim through the signup link, complete the account steps, make a first-time deposit and place a real-money trade. Now, even though the bonus is easy to trigger, the window is short. The $25 Predicts Bonus expires seven days after it is credited, so this one makes more sense when there are active markets you already want to trade during that week.

Once you claim the welcome bonus at FanDuel Predicts, take advantage of the app’s existing-user promos:

• Refer-a-Friend Bonus: Earn $20 per friend you successfully refer. They must sign up through your unique referral link and deposit/trade at least $5 within 30 days of signing up. You can refer up to five friends per 30 days.

3. Kalshi: Longest-Standing Prediction Market Promo in the U.S.

Kalshi bases its offer on cumulative trading volume, so you don't have to place the full qualifying amount on one contract. New users need to complete $10 in eligible trades to earn the $15 credit, which leaves some room to split the requirement across smaller positions.

Use promo code ACTION at signup, then check the Rewards section for the credit status and expiration date.

After claiming the welcome bonus, you’ll gain access to existing-user promos at Kalshi:

• Refer-a-Friend Promo: Referral offers can vary by account and campaign. The Rewards section shows the current bonus, qualifying activity, and claim deadline attached to your link. For more info, check out our review of Kalshi's Refer-a-Friend Program.
• Volume Incentive Program: This program rewards active traders who match with existing prices to buy or sell contracts.
• Liquidity Incentive Program: Get paid cash rewards for placing resting limit orders that sit on the order books and help other traders get better prices, even if your orders never get filled.

4. Novig: Simplest Sweepstakes Promo

New Novig users can use promo code ACTION to Spend $25, Get $50 in Novig Coins! The key difference is that Novig Coins are free-play currency, not cash, so the $50 headline should not be compared directly to a trading-credit bonus from Kalshi, FanDuel Predicts or ProphetX.

Novig Coins are useful if you want to learn the app, test sports markets and build tickets without using real-money funds. They cannot be withdrawn or exchanged for cash.

Novig also runs promotions for existing users, though they work differently from its signup offer. The referral program awards 25 Novig Cash to both users after the invited player signs up through the referral link and purchases at least 25 Novig Coins. Coins, Cash and Points are separate balances, so the value depends on which reward type is issued and how it can be used.

Novig Points are tied to eligible activity and in-app challenges. The available tiers, monthly prize pools and reward conditions are live in the app. The value here depends on how often you use the platform rather than a single qualifying purchase. 

5. ProphetX: Best Return on Deposit

Use the ProphetX promo code TANBONUS to Trade $10, Get $20!

ProphetX has one of the better bonus-to-qualifying-trade ratios on this page. You just need to place one trade of at least $10, and you’ll usually get the $20 bonus within a day. Just remember that you can’t withdraw the bonus itself. Instead, use it to place trades, and you can withdraw any winnings you make from those trades.

Other promos at ProphetX:

• Refer-a-Friend Bonuses: ProphetX offers a tiered referral program, rewarding users with $25 for each qualifying friend. Referrals must sign up and meet wagering requirements within 14 days to qualify for the bonus.

How to Claim Prediction Market Promos

Each platform has its own qualifying trigger, so the first step is checking what actually gets you the offer. This is where most people make mistakes, because they assume a deposit alone is enough, or they miss a small requirement that prevents the bonus from triggering.

Here’s the breakdown:

• Polymarket: Make your first qualifying deposit.
• FanDuel Predicts: Make a deposit and place your first real-money trade.
• Kalshi: Complete the required trading volume, which you can reach across multiple trades.
• Novig: Buy at least $25 worth of Novig Coins.
• ProphetX: Place one trade of at least $10.

Promo codes also vary by platform. Polymarket and Kalshi use ACTION, while ProphetX uses TANBONUS. FanDuel Predicts doesn’t require a code, but you do need to sign up through the qualifying link.

Once your bonus is credited, take a moment to confirm exactly how it works before placing a trade. Some bonuses are automatically applied to your next position, while others require you to opt in or choose them manually. It’s also worth checking whether the bonus can be split across multiple trades or has be used in a single position.

Timing is another key factor. FanDuel Predicts gives you seven days to use your bonus, Kalshi gives you 30 days, and ProphetX gives you 45 days. Polymarket’s window can range from seven to 30 days depending on the offer. If you wait too long or forget about the expiration, the bonus simply disappears. Also, in most cases, you can’t withdraw the bonus itself. Instead, you use it to place trades and can withdraw any eligible winnings from those trades. Novig works differently, as Novig Coins are free-play currency and can’t be cashed out.

Long story short, claiming the bonus is only part of the process. You also need to understand how it’s applied, how long you have to use it, and what counts as a valid trade. Once you’re clear on those details, you can start thinking about which types of promos are actually worth using and how they fit into your trading approach.

Popular Types of Prediction Market Promos and Bonuses

Prediction market promos come in all shapes and sizes:

• Deposit Promos: Bonus credits after you add money to your account. Usually comes with a minimum deposit amount.
• Signup Bonuses: Rewards you simply for creating an account and completing identity verification. Rarer, as most apps want buy-in from users.
• Trade Bonuses: Credits unlocked after a qualifying trade. Usually comes with a minimum trade amount.
• Purchase Matches/Bonuses: Common on sweepstakes-style platforms. You may receive virtual currency rewards tied to your first purchase.
• Referral Programs: Rewards for existing users who bring in new users, usually after their referral verifies, deposits, or trades.
• Liquidity/Volume Rewards: Rewards for active traders who post orders or trade certain volume to improve market depth.

July Sports to Use Prediction Market Promos On

Mid-July is a great time to try out prediction markets because there’s a lot going on, but not every market works the same way. Some settle quickly (like within a few hours), while others can stay open for days or even weeks. That means you don’t need to rush into a trade just because you have a bonus to use.

Here are some of the main sports you’ll see around this time, along with what to watch for:

• 2026 World Cup: The tournament is down to the semifinals with France vs. Spain on Tuesday, July 14, and England vs. Argentina on Wednesday, July 15, before the final on Sunday, July 19. You'll see different types of markets, like who wins the match, who advances, or who wins the whole tournament. These can look similar, but they don't always settle the same way. For example, some contracts end after 90 minutes, while others include extra time and penalties.
• MLB: Baseball games happen almost every day, so there are lots of short-term options. Just keep in mind prices can change quickly based on things like starting pitchers, weather, or last-minute lineup updates. Longer-term markets, like picking a division winner, will keep your money tied up for much longer.
• WNBA: Prices can move fast here too, especially with injuries, rest days, or travel schedules. Some games also have less activity (called liquidity), so it’s a good idea to check how big the gap is between the buy and sell price before placing a trade.
• Tennis: Prices can change on a single break of serve, so markets move fast. Pay attention to retirement rules, too: some contracts only count if the full match is completed, while others don't.
• Golf: The Open Championship starts July 16. You can choose from different types of markets, like picking the overall winner, head-to-head matchups, or even round-by-round results. Remember weather and tee times can affect prices before players even start.

One simple rule to keep in mind: price makes a big difference. If a “Yes” contract costs 60 cents, that means the market thinks there’s about a 60% chance it'll happen. So even if you like a team or player, the price still needs to make sense for it to be a good trade.

Using Prediction Market Promos on 2026 World Cup Markets

The World Cup is a good place to put a promo to work right now, with the tournament down to its final four. France meets Spain on Tuesday, July 14, England faces Argentina on Wednesday, July 15, and the winners meet in the final on Sunday, July 19. That leaves you a lot of high-volume matches, plus outright markets on who lifts the trophy.

Just know that not every World Cup market settles the same way, even when the wording looks almost identical. Some only count the first 90 minutes, so a match that goes to extra time or penalties may have already settled as a draw on a regulation-time contract. A team-to-advance market is different again, as it stays open until one side actually goes through. Same match, different contract, so definitely read the settlement rules before you trade.

So before entering a trade, run through these things:

• What has to happen for the contract to settle
• When the market closes and settles
• The current buy and sell prices
• How much is available near your preferred price
• Whether you plan to hold through settlement or exit earlier

The wording can look similar across World Cup markets, especially ones involving the same teams, so take your time with the settlement rules before entering. A regulation-time contract, a team-to-advance market, and a tournament-winner future can each give you very different exposure.

Trade Prediction Market Bonuses Responsibly

While prediction markets involve the trading of event contracts, they can feel similar to gambling. You can lose money, overtrade and chase a bad read because the price moved against you.

Even when trading with prediction market bonus funds, you should always prioritize responsible trading principles. This way, when your bonus funds run out, you can trade responsibly with money you deposit yourself.

Practical tips include:

1. Set a budget before you trade

2. Keep trade sizes reasonable

3. Take breaks

4. Use responsible trading tools when available, including deposit limits, time-outs, self-exclusion, account history and transaction records.

If trading starts affecting your finances, sleep, work or relationships, step back and get support at 1-800-MY-RESET or 1-800-GAMBLER.
