Best Prediction Market Promos in June 2026

✅​ Prediction Market Promo Codes last verified on June 13, 2026

1️⃣ Polymarket — Highest Value Signup Bonus

The Polymarket promo code ACTION grants the highest value prediction market promo available in June 2026.

The barrier to entry is a bit higher than it is for other promos, as you must make a $20 deposit.

However, the $50 bonus means that you'll more than double your initial deposit.

And the 30-day window to use your funds is generous compared to many competitor promos, giving you plenty of time to use this large bonus.

Polymarket's overall low fees mean that once you play through this bonus, you can retain much of the promo's cashout value (as long as you make profitable trades).

📱 Where to Claim	App only

After you claim the welcome bonus at Polymarket, you can take advantage of the app's existing-user promos:

• Liquidity & Volume Rewards: Polymarket rewards users who add "liquidity" to the books. If you place limit orders (orders that sit on the book waiting for someone else to fill them) on specific high-profile markets, Polymarket distributes cash rewards directly to your account based on how tight your prices are and how long your orders sit there.
• Refer-a-Friend: Polymarket’s peer-to-peer referral program is built for serious traders. To unlock your unique referral link to invite friends, your account must first hit $10,000 in lifetime trading volume. Then, you'll get a cut of the fees your friend's trades generate for the first 180 days (30% of trading fees from your direct referrals, 10% from indirect referrals).

2️⃣ FanDuel Predicts — Most Straightforward

Claiming the FanDuel Predicts welcome bonus might be a little confusing at first, as there's no FanDuel Predicts promo code for new users to enter.

Rather, new users can claim the signup offer by registering via the FanDuel Predicts links on this page. Just use Action Network's secure and verified links to qualify.

We like this signup bonus because of its simplicity — all you have to do is make an initial deposit & trade of $10 to get the $25 bonus.

It's a relatively high-value welcome bonus with a small trade requirement.

One drawback is the 7-day expiration window, so just make sure you have a plan to use your bonus funds timely.

Another important note: FanDuel Predicts will automatically use your bonus funds before touching your deposited cash.

3️⃣ Kalshi — Promo That Has Stood the Test of Time

Kalshi promo code ACTION is the first prediction market promo we reviewed here at Action Network.

It was strong from the beginning and continues to be a competitive signup bonus, clearly having stood the test of time.

All you have to do to qualify is deposit/trade $10. The $10 reward is a bit lower than we've seen at other prediction markets, but favorable terms such as the 30-day expiration window more than make up for it.

🏷️ Kalshi Promo Code	ACTION
🎁 Kalshi Welcome Bonus	Trade $10, Get $10!
📝  Promo Terms & Conditions	Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NV, and OH.
📍 Eligible States for Promo	AK, AL, AR, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IN, KS, KY, LA, ME, MN, MO, MS, NC, ND, NE, NH, NJ, NM, NY, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WA, WI, WV, WY
💰 Type of Signup Bonus	First-trade match
⌛ Expiration	30 days
💵 Minimum Deposit Requirement	$10
📱 Where to Claim	App and desktop

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

• Refer-a-Friend Promo: When you successfully refer friends to Kalshi via your referral link, you each get a $25 trading credit. Your friend must complete 100 individual trades within 30 days to trigger the payout, and your lifetime referral earnings are capped at $1,000.
• Volume Incentive Program: This program rewards you simply for being highly active in a market. If you're a trader who goes in and immediately matches with existing prices to buy or sell contracts, Kalshi pays you back.
• Liquidity Incentive Program: Get paid cash rewards for placing resting "limit" orders that sit on the order books, helping other traders get better prices even if your orders never get filled.

4️⃣ Novig — Simplest Sweepstakes Promo

The Novig promo code ACTION grants a welcome offer that's fairly different from the promos at Polymarket, FanDuel Predicts, and Kalshi.

Seeing as Novig is a sweepstakes-style prediction market for the time being, the welcome offer is a purchase match. You must purchase at least $5 worth of Novig Coins to qualify for the $50 bonus.

The $50 comes in the form of Novig Coins, which is the virtual currency at Novig you can use to make predictions for fun. If your purchase comes with a bonus of Novig Cash, you can use this virtual currency to compete for real money prizes.

With Novig having applied for CFTC approval, this welcome offer may evolve into a more traditional deposit/trading match. Stay tuned for updates.

🏷️ Novig Promo Code	ACTION
🎁 Novig Welcome Bonus	Spend $5, Get $50 in Novig Coins!
📝  Promo Terms & Conditions	Players must be 21+ and be residents of the U.S. Void where prohibited. Mobile only. Please play responsibly.
📍 Eligible States for Promo	AK, AR, CA, FL, GA, HI, IL, IN, IA, KS, KY, ME, MA, MN, MO, NE, NH, NC, ND, OH, OK, OR, SC, SD, TX, VT, VA, DC, WI, WY
💰 Type of Signup Bonus	First-purchase bonus
⌛ Expiration	7 days for Novig Coins
💵 Minimum Purchase Requirement	$5
📱 Where to Claim	Promo is app only, though Novig is also available on desktop

Other promos at Novig include:

• Refer-a-Friend Bonus: Share your unique referral code with friends. When they sign up for Novig via your code and purchase at least $25, you'll both get 25 in Novig Cash.
• Novig Points: This loyalty program rewards users for making trades and completing challenges. As you climb the tiers, you'll unlock perks such as purchase ematches. And at the end of each month, you can earn a share of the prize pool based on your trading activity.

5️⃣ ProphetX — Optimal Sweepstakes Promo to Compete for Real Money Prizes

Like Novig, ProphetX is a sweepstakes sports prediction exchange, but their welcome promos look different.

ProphetX promo code ACTION unlocks a purchase match, meaning your reward is based on the amount of your initial purchase.

Note that you have to put in more to maximize the offer. You can meet the minimum purchase requirement of $10, but you'd only get $2 in Prophet Cash as a reward since it's a 20% match.

The offer caps at $100, so if you want to make the most of it, you'd have to make an initial purchase of $500.

That being said, this signup bonus still offers plenty of flexibility. And the best part is that the reward comes as Prophet Cash rather than Prophet Points, meaning you can use your reward to compete for real money prizes.

Now that ProphetX has CFTC approval, we're waiting to see what the fully federally regulated app will look like. It'll likely include a new prediction market promo, so stay tuned for updates from Action Network.

🏷️ ProphetX Promo Code	ACTION
🎁 ProphetX Welcome Bonus	Get a 20% Purchase Match up to $100 in Bonus Funds!
📝  Promo Terms & Conditions	Players must be 19+ and be residents of the U.S. Void where prohibited. Please play responsibly.
📍 Eligible States for Promo	AL, AK, AZ, AR, CA, CO, CT, DE, FL, GA, HI, ID, IL, IN, IA, KS, KY, LA, ME, MD, MA, MI, MN, MS, MO, MT, NE, NV, NH, NJ, NM, NY, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY
💰 Type of Signup Bonus	First-purchase bonus
⌛ Expiration	14 days
💵 Minimum Purchase Requirement	$10
📱 Where to Claim	App only

Beyond the signup bonus, existing-user promos at ProphetX include:

• Refer-a-Friend Bonus: Get friends to sign up for ProphetX via your unique referral link. The amount of Prophet Cash received for each referral starts at 25 Prophet Cash and increases by 5 for each successful referral until reaching a maximum of 50.
• Liquidity Rewards Program: Geared toward more advanced traders, this program compensates those who submit resting "limit" orders that sit on the public order book instead of immediately executing.

How to Claim Prediction Market Promos

It all starts with the correct sign up flow.

• If a promo code is required, enter it before creating your account or making your first deposit.

• If no code is needed, you should click the link on this page to the offer and create an account.

Keep in mind most prediction market platforms require a KYC check before you trade, deposit or withdraw.

Pay careful attention to the promo's terms, as most require an initial deposit and/or trade of a specified amount.

Also, be aware that bonus funds at prediction markets carry trade-through requirements. It's similar to the playthrough/wagering requirements at sportsbooks, which prevent users from withdrawing the bonus amount immediately.

You must trade through the funds first, and only profits are eligible for withdrawal.

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.

June Sports to Use Top Prediction Market Promos On

From championship series, daily MLB, the WNBA season, a golf major, Wimbledon and the World Cup, June is a GREAT month to have bonus prediction market credits available.

• NBA Finals: NBA Finals markets can include game winners, series outcomes and player-driven contracts. One injury update or rotation change can move prices fast.

• Stanley Cup Final: The Stanley Cup Final gives hockey traders series markets, game markets and a lot of momentum swings.

• 2026 FIFA World Cup: The World Cup runs from June 11 to July 19, 2026. Expect interest in match winners, group outcomes, advancement markets and country-specific contracts.

• MLB Season: MLB is the daily volume play. Game winners, division races and futures give active traders more ways to use promo credits over time.

• WNBA Season: WNBA trading can reward users who follow injuries, rotations and matchup news more closely than casual fans.

• PGA Tour U.S. Open: The U.S. Open runs June 18-21, 2026, at Shinnecock Hills. Golf markets can move round by round, especially when weather and tee times make an appearance.

• Wimbledon: Wimbledon runs from June 29 to July 12, 2026. Tennis markets usually move quickly because one set, one medical timeout or one bad service game can change the board.

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.
