Best Prediction Market Promos and How to Sign Up (September 2026)

Polymarket is our top recommendation for this week. College football's Week 2 slate runs Friday and Saturday, headlined by No. 1 Ohio State at Texas; the NFL's first full Sunday of the season lands September 13; the US Open crowns its champions Saturday and Sunday in New York; and baseball is running nightly, with the regular season ending September 27.

You'll find markets on game winners, spreads, season win totals, conference and championship futures across both the NFL and college football. There's tennis, baseball, and a lot that has nothing to do with sports too.

Sign up with promo code ACTION, deposit $10, and your $50 trading bonus is credited once the qualifying deposit clears. No first trade is needed to trigger the bonus.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See polymarket.com/tos for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.

Prediction market platforms often provide welcome offers for new users. We compared these offers by usable bonus value, qualifying cost, expiration window, platform fees, state availability, and how easy the claim process is.

Eligible users may qualify for more than one offer, but each platform has its own identity checks, funding rules, and trade requirements. Review the table and full terms before creating an account.

✅​ Prediction Market Promo Codes last verified on September 11, 2026

Polymarket's welcome bonus is a flat $50 in trading credit for a $10 deposit, with no qualifying trade required.

You know what you're getting here before you sign up, and you don't have to trade to trigger the bonus. Enter the Polymarket promo code ACTION, deposit $10, and the $50 trading bonus is credited once the qualifying deposit clears. The amount is fixed, so you know the value of the offer before you sign up.

The important distinction is that it's trading credit, not cash. Use the credit on eligible trades, and eligible profits can be withdrawn in accordance with the offer terms after settlement. Polymarket also offers a large range of markets, which gives you plenty of options when you're ready to trade.

How the bonus works

Make a qualifying first deposit of at least $10 with promo code ACTION applied during signup. Once the deposit clears and the offer requirements are met, eligible new users receive the $50 trading bonus in their account.

Deposit timing can vary by payment method. Check your Balance/Wallet and the terms attached to your offer to confirm when the bonus has posted and when it expires.

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.

You don't need a promo code for FanDuel Predicts — sign up through the offer link and the welcome bonus attaches to your account.

No code to type, nothing to paste in. Create your account, clear verification, and you're trading. If you've ever missed out on a bonus because you forgot to enter a code, that can't happen here.

Sign up through our link to make sure the offer attaches to your account, and take it from there.

What I found testing it

No code, as advertised. I created an account, completed verification, and had access straight away. I deposited $10 — the minimum — with a Visa debit card, and it went through in a few minutes.

The app itself is mobile-first, clean, and built around simple yes/no questions, with sports sitting alongside financial and cultural markets.

Two things caught me out. If you already have a FanDuel sportsbook account, this is a separate app with a separate wallet — you can't share funds between them, and funding is limited to debit cards, Apple Pay and ACH. No PayPal or other digital wallets, which is a step down from what FanDuel customers are used to. And in states where sports betting is legal, the sports markets are blocked on Predicts. I ended up trading entertainment, economics and financial markets instead, and using the sportsbook app for anything sporting.

This offer is ranked on how easy it is to claim, not on size, because FanDuel doesn't publish a figure for it. That's why it sits second rather than first. The practical upside is that you're not committing anything to find out: sign up through our link, see what's attached to your account, and decide about depositing once you know what you're working with.

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.

You can reach the $25 trade requirement for the Kalshi bonus across a few smaller trades instead of one, and they count win or lose. What you get back is a flat $25 bonus once you complete the requirement. 

Enter promo code  at signup, and once the credit posts, the Rewards section shows your amount and when it expires.

Kalshi's bonus is straightforward: once you meet the $25 trade requirement, you receive a guaranteed $25 bonus.  

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.

New Novig users can use Novig promo code ACTION to [Deposit $10, Get $25 in Trade Credits!

Now that Novig is CFTC-regulated rather than a sweepstakes prediction market, the bonus rewards in Trade Credits instead of virtual currencies.

Novig also runs promotions for existing users, though they work differently from its signup offer.

• Referral: The referral program awards $25 to you and your friend when your friend signs up via your referral link.
• Novig Points: 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 largely depends on how often you use the platform.  

Use the ProphetX promo code TANBONUS to Trade $50, Get $75!

Trade $50, get $75, one of the best ratios on this page. One trade of $50 or more within 30 days of opening your account, and you're done: no installments and nothing extra to track.

What I found testing it

Signup took a few minutes, plus email and phone verification. The code came pre-filled from the link, so I skipped that step. I put in $50, traded it on MLB, WNBA, and a few daily games, and the $75 arrived within 24 hours, just as promised.

Funding is the awkward part. No debit cards, no Apple Pay, no Google Pay — it's online banking through Aeropay, crypto through ZeroHash, or a wire. I opened a ZeroHash account and paid in crypto. Fast enough, but it's another account to set up first.

ProphetX also only does sports. No pop culture, no crypto prices, no elections. Perfect if that's why you're here, frustrating if you wanted Kalshi's range.

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.
• America's #1 Hater: A free-to-enter NFL survivor pool with a twist. Each week you pick one running back you're confident won't score a touchdown; if he scores, you're out. Picks lock at the first snap of that back's game, and any back you've used is off the board for the rest of the season. Survive to Week 18 and the $10,000 cash prize is yours, split if more than one entrant is still alive. Must be 21 or older and in an eligible jurisdiction.

• Best guaranteed value: Polymarket (ACTION), flat $50 on a $10 deposit, no qualifying trade.

• Best platform with sports betting roots: FanDuel Predicts, familiar interface and instant funding.

• Best 1-to-1 return: Kalshi, Trade $25, Get $25!

• Low barrier to entry: Novig (ACTION), $10 initial deposit required
• Best return on a small buy-in: ProphetX (TANBONUS), $20 bonus on a $10 trade, with a simple single-trade qualification.

Action Network rates prediction market promos by usable value, not just the number. We look at:

• Platform fees that may affect overall bonus value
• ​State availability
• ​Ease of claiming the promo

If you want to see how we rank these platforms beyond their signup bonuses, check out our review of the best prediction market apps.

Every platform has its own trigger, so your first job is knowing what actually unlocks the offer. This is where people slip up. They assume a deposit is enough, or miss a small requirement that keeps the bonus from landing. Here's the process, step by step.

Here's what triggers each bonus:

• Polymarket: Make your first qualifying deposit.
• FanDuel Predicts: Sign up and verify through the qualifying link.
• Kalshi: Hit the required trading volume. You can reach it across several trades.
• Novig: Deposit at least $10.
• ProphetX: Place one trade of at least $50 within 30 days of account approval.

Promo codes vary by platform. Polymarket and Kalshi use ACTION, while ProphetX uses TANBONUS. 

FanDuel Predicts and DraftKings Predictions don’t need a promo code. You’ll still want to sign up through the qualifying offer link in this page so the right promotion is attached to your account, though.

Got your bonus? Check how it works before you trade, then go into the Rewards/Promotions section and check if the bonus shows as active or pending. Some bonuses apply automatically to your next position, others make you opt in or pick them by hand.

DraftKings Predictions is the one to keep an eye on here. Its $200 offer is split into $50 Predictions Dollar every 7 days via click-to-claim for 21 days. The later rewards are click-to-claim and expire seven days after they’re issued.

Timing matters just as much as claiming. Kalshi gives you 7 days to use the bonus, while Novig gives you 30 and ProphetX gives you 45 days. Polymarket's window runs 7 to 30 days depending on the offer. Miss the deadline and the bonus expires. DraftKings Predictions Dollars, on the other hand, expire one year after issuance, but don’t confuse that with the claim window. The $50 click-to-claims expire after 7 days, so you still need to log in and claim them on time.

Remember: you usually can’t withdraw bonus credit itself. Check the terms before placing a trade so you know how the credit works and when it disappears.

Bottom line: claiming is only half the job. Know how the bonus applies, how long you've got, and what counts as a valid trade. Nail those, and you're ready to work out which promos are actually worth your time.

How you fund your account matters when you're claiming a promo.

Debit cards and online banking are instant, so your deposit clears in time to trigger the bonus. Just watch the minimums, since most offers here need $5 to $25 to qualify.

ACH and debit are the most reliable payout methods, while mobile wallets like Apple Pay often can't be used for withdrawals, so don't count on cashing out the way you paid in.

Choose the method you're most conformable with, but remember: promo credit itself never comes out. Whether it's Predictions Dollars or trading credit, you can only withdraw what you win trading with it.

Short version: yes. The bonuses are real, and the platforms behind them are regulated by the Commodity Futures Trading Commission (CFTC).

These offers work like the free credit a brokerage gives you to open an account. The thing to watch isn't whether they're real, it's the terms, so know what triggers the bonus, when it expires, and what you can withdraw.

The trust comes from the oversight. Platforms like Kalshi and Polymarket's U.S. app answer to the Commodity Futures Trading Commission (CFTC), the federal agency behind futures and derivatives. It treats event contracts as financial instruments, not bets, so you're signing up with a regulated company rather than a fly-by-night site.

• 1️⃣ Look For The Regulator: A real platform names its oversight, usually the CFTC, and its legal entity.

• 2️⃣ Find Out How To Activate Welcome Bonus & Offer Expiry Date: A legit offer tells you exactly what unlocks the bonus and how long you've got.
• 3️⃣ Read Trading Requirements: Bonus credit itself is generally non-withdrawable, so check what qualifying trading activity is required and how eligible profits are treated.
• 4️⃣ Only Claim Bonuses Through Trusted Links: Use a verified source so the offer attaches, and skip any "code" from a random DM or forum.

Prediction market promos come in all shapes and sizes. Here are some of the different bonuses offered by popular prediction markets:

• 1️⃣ Deposit Promos: Bonus credits after you add money to your account. Usually comes with a minimum deposit amount.
• 2️⃣ Signup Bonuses: Rewards you simply for creating an account and completing identity verification. Rarer, as most apps want buy-in from users.
• 3️⃣ Trade Bonuses: Credits unlocked after a qualifying trade. Usually comes with a minimum trade amount.
• 4️⃣ Purchase Matches and Bonuses: Common on sweepstakes-style platforms. You may receive virtual currency rewards tied to your first purchase.
• 5️⃣ Referral Programs: Rewards for existing users who bring in new users, usually after their referral verifies, deposits, or trades.
• 6️⃣ Liquidity and Volume Rewards: Rewards for active traders who post orders or trade certain volume to improve market depth.

September doesn't leave many empty spots on the sports calendar. MLB is deep into the stretch run, college football owns much of Friday and Saturday, NFL Week 1 is underway, and the US Open is down to its final weekend in Queens.

Baseball can start moving well before the first pitch. A starting-pitcher change, a late scratch or weather around an outdoor park can all move a game contract in quickly. September makes those details harder to ignore, especially with playoff races tightening and clubs changing lineups more aggressively.

Football works on a different clock. The NFL portion of this window is concentrated on Sunday and Monday, with afternoon games feeding into Sunday Night Football before a standalone Monday night matchup. That gives you lots entry points if you're using a prediction market promo instead of trying to squeeze everything into one kickoff window. There's no NFL game scheduled for Tuesday, Sept. 15.

College football has a similar spread across the weekend. Friday night leads into a Saturday schedule with major games starting at noon ET. A contract tied to a noon kickoff at Michigan Stadium in Ann Arbor can move much faster than a conference or championship market you're holding for days, so check the exact settlement terms before trading.

Tennis can turn even faster. One break of serve can move a match contract sharply, and the US Open's final weekend leaves little room for a slow read. Retirement and walkover rules are worth checking before you enter, especially when platforms don't settle those situations the same way.

Promos and timing go hand-in-hand, but bonus credit isn't a reason to force a trade. Check that the contract is available where you live, compare the buy and sell prices, and read the settlement rules before committing.

These are some of the biggest confirmed events from Friday, Sept. 11 through Tuesday, Sept. 15. Contract availability can differ by platform and location, so check your prediction market app before planning around a specific event.

If you're mainly looking at pro football contracts, see our guide to the best NFL prediction market promos. We also track the top CFB promos for prediction market users throughout the college football season.

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 the platform's own tools — deposit limits, time-outs, account history and transaction records. Kalshi also runs a consumer protection hub with voluntary opt-outs.
5. If you've already self-excluded from sportsbooks, it doesn't carry over. State self-exclusion covers state-licensed operators, and these platforms are federally registered, so they sit outside it. For a cross-platform block, SelfExclude (run by IC360) covers participating prediction markets — Kalshi is integrated and others are joining. Once you set a period, it can't be lifted early.

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