To claim a prediction market promotion, use the official offer path, confirm that it is still active and available where you are, attach any required code by the deadline, complete the stated eligibility and onboarding steps, then check the account’s Rewards or Activity screen for a claim action and posted credit. A code by itself does not prove you qualify. Read the offer’s terms before depositing or trading: requirements, credit restrictions and expiry vary by program.
Check the offer before you act
Start by identifying the exact product and promotion: a platform referral program, a U.S.-specific incentive and a one-off promotion can have different terms, even when they use the same brand. Open the official offer and check that it is still live; do not rely on an old code or a third-party summary.
- Location and account status: Check age, country, state or physical-location rules, whether the offer is limited to new users, and any identity-verification requirement or exclusion.
- Code timing: Find out whether you must use a link or enter a code before or during signup, or whether there is a limited post-signup window. Check whether making a deposit closes that window.
- Qualifying actions: Confirm the exact onboarding, deposit, trade or other condition. A deposit or trade should not be assumed to qualify unless the offer says it does.
- Reward terms: Establish whether the benefit is cash, trading credit or a fee rebate; how it can be used or withdrawn; whether it expires; and whether it is a fixed or account-specific amount.
- Claim and confirmation: Look for an unlock or claim step, then check the account’s rewards or activity record to confirm the credit was issued.
If the terms are unclear or the account does not show the offer, ask the platform’s support team before taking an action that may be irreversible.
Claim a Kalshi referral offer
Kalshi’s Referral Program FAQ, dated August 25, 2026, says to enter a referral code during signup when possible. In some cases, a code can be added after signup, but only within 72 hours of the first login or account creation and before the first deposit—whichever comes first. Once applied, a code cannot be replaced. Kalshi says a valid referral link or code and completed identity verification (KYC) are basic requirements, and its general referral incentives are currently available only to U.S. users. Individual offers may impose additional limits. Read Kalshi’s referral program terms.
#1 Best Overall
- Check your account’s offer and requirements. In Kalshi, go to Menu → Referrals or Rewards. The reward amount and qualifying requirements depend on the program that applies to your account.
- Apply the code within the stated window. If the code is not attached during signup, the limited post-signup option may be available only before the deadline described above and before your first deposit.
- Complete the offer’s stated steps. Finish identity verification and any other requirements shown for that offer; do not assume that a deposit alone unlocks a reward.
- Check for a claim action and confirm the credit. A credit may post automatically, or an onboarding banner may prompt you to tap Unlock bonus amount or Claim. Check Activity → Credit for account activity.
Kalshi says referral credits are intended for trading and the original credit usually is not withdrawable; profits made using it may be withdrawable cash. Credits usually expire seven days after issuance unless the offer says otherwise, and expired credits cannot be reinstated. Use the expiry shown in your own Rewards/Referrals Hub or Portfolio → Credit, rather than assuming every credit has the same deadline.
Do not confuse Polymarket referral rewards with Polymarket US’s user incentive
Polymarket and Polymarket US have separate published program descriptions. The Polymarket Help Center page, dated June 24, 2026, describes rewards to referrers based on net fees from referred accounts. A separate filing by Polymarket US operator QCX LLC describes a one-time incentive for qualifying referred users. These are not interchangeable offers; check which service and terms your account actually presents.

| Program described | Who may qualify and how | Published benefit and limits |
|---|---|---|
| Polymarket referral program | The referrer must have $10,000 in lifetime trading volume. A referred user must sign up within 30 days of clicking the referrer’s market or profile link. | The Help Center lists 10% of net fees from direct referrals and 5% from indirect referrals. Rewards apply for the first 30 days after signup or until the referred account reaches Platinum, whichever comes first. Not all markets have fees, so trading volume alone does not ensure a referral reward. |
| Polymarket US / QCX LLC 2026 Referral Incentive Program | The January 16, 2026 filing describes a first-time user who uses a referral code, is successfully onboarded and deposits at least $10 within 30 days. | The filing describes a one-time $10 account credit. Incentive funds are applied as original margin on new positions and may be withdrawn upon position settlement or liquidation. The filing says the program and terms may be amended; it does not establish that every reader or jurisdiction can access the offer today. |
For the platform referral program, see Polymarket’s referral program terms. For the separate U.S. incentive, consult the Polymarket US / QCX LLC filing and the current offer shown in your account.

A platform’s general referral rules do not necessarily determine eligibility for a specific promotion. For example, the completed Kalshi World Cup promotion required a valid KYC-approved account, age 18 or older and physical presence in the U.S.; it excluded New York and Florida residents or people located there. Its entry period ran from June 4, 2026, until kickoff of the first match on June 11, 2026. Those were rules for that promotion, not universal Kalshi referral terms, and the promotion is over. Its official rules illustrate why you should read the terms attached to the specific offer you intend to claim.

If the promo does not appear or the credit is missing
- Recheck the correct product and account. Make sure you followed the offer for the service you use, rather than a similar program from another product or region.
- Check the code deadline and account history. A late code, a first deposit made before attaching it, or an already-applied code may prevent a change or claim.
- Review every qualification. Verify location, new-user status, identity verification, deposit or trading conditions, and the offer’s live dates against its terms.
- Look for an unlock step and the right activity screen. On Kalshi, check the Rewards or Referrals area and Activity → Credit; use the expiry displayed for your own account.
- Contact official support before repeating a deposit or trade. Ask whether the account met the offer’s terms and whether a credit is pending. Do not take additional financial risk merely to pursue a bonus unless you have independently decided the activity makes sense for you.
