A promo code alone does not prove you qualify: offers can be limited by product, location, account status, timing, and the specific action required.
Check these terms before you sign up, deposit, or trade
Read the actual offer rules before taking an action that may close an eligibility window. Use this checklist to establish whether the promotion fits your account:
As an Amazon Associate I earn from qualifying purchases.
- Platform and product: Confirm whether the offer is for a general platform referral program, a U.S.-specific service, or a one-time promotion. Similar names do not mean the same terms.
- Offer dates: Check the start and end dates and make sure the official offer is still active. A previously published offer may have ended or changed.
- Your eligibility: Review age, country, state or physical-location restrictions, new-user status, identity verification, and any exclusions in the offer’s rules.
- Code timing: Find out whether the code must be used before signup, during signup, or within a specific period afterward. Check whether making a deposit ends the window.
- Qualifying actions: Identify exactly what counts, such as completing onboarding, depositing a minimum amount, or meeting a specified trading condition. Do not assume any deposit or trade qualifies.
- Reward type and expiry: Determine whether the benefit is cash, trading credit, or a fee-based referral reward; how it can be used or withdrawn; and when it expires.
- Claim and confirmation: Look for a claim or unlock button, then verify the reward in the account’s Rewards, Referrals, or activity screen.
For two offers you are considering, compare these terms side by side before acting:

| What to compare | What to verify |
|---|---|
| Who qualifies | Eligible locations, age, new-user status, and account verification requirements. |
| How to attach the offer | Where to enter the code, the deadline, and whether a deposit or another step closes the window. |
| What you must do | The precise onboarding, deposit, or qualifying activity required. |
| What you receive | Reward amount or calculation, whether it is cash or credit, and any use or withdrawal restrictions. |
| How and when you receive it | Whether it posts automatically or requires a claim, plus the expiry date. |
| Referrer-program terms | Any referrer volume threshold, fee basis, reward period, caps, and disqualification terms. |
How to claim an offer
- Open the official offer. Start from the platform’s official promotion page or the referral link associated with the offer. Confirm that it names the product and promotion you intend to use.
- Read the complete terms. Note the location and account rules, code deadline, qualifying actions, reward type, claim method, and expiry before depositing or trading.
- Apply the code at the required time. Enter it in the offer’s stated signup or referral flow. If the platform allows a post-signup code, follow its exact deadline and any condition tied to the first deposit.
- Complete the stated eligibility steps. Finish identity checks and only complete a deposit or other action if the offer’s terms require it and you are eligible. A deposit alone should not be treated as proof of qualification.
- Check for a claim action. Open the account’s Rewards or Referrals area and look for an unlock, claim, or onboarding step. Some rewards post automatically; others require a user action.
- Confirm the credit and its terms. Review account activity or the credit screen for the posted amount, permitted use, and expiry. If it is missing, contact the platform through its official support route before repeating a qualifying action.
Kalshi: referral-code timing, reward claim, and credit limits
Kalshi’s Referral Program FAQ, dated August 25, 2026, says a referral code can be entered during signup. Sometimes a code can be added after account creation, but only within 72 hours of the first login/account creation and before the first deposit, whichever happens first. Once applied, the code cannot be replaced. The FAQ also requires a valid referral link or code and completed identity verification, and says referral incentives are currently available only to U.S. users. Individual promotions may add narrower restrictions. Read Kalshi’s referral-code terms.
#1 Best Overall
Kalshi says reward amounts and trading requirements depend on the program applicable to the account. Check Menu → Referrals or Menu → Rewards. A credit may arrive automatically, or an onboarding banner may ask you to choose Unlock bonus amount or Claim. To check account activity, use Activity → Credit.
Kalshi describes referral credits as trading credit, not cash: the original credit is generally not withdrawable, while profits made using it become withdrawable cash. Issued credits usually expire seven days after issuance unless the offer says otherwise; expired credits cannot be reinstated. Check the expiry shown in your Rewards/Referrals Hub or Portfolio → Credit, because the offer’s own terms control.
Polymarket and Polymarket US have different referral offers
Do not treat these as a single promotion. The Polymarket Help Center’s referral-program description is for Polymarket; a separate public filing describes an incentive for Polymarket US. Confirm the service shown in your account and check its current offer before proceeding.
Polymarket referral program
In a Help Center page dated June 24, 2026, Polymarket says a referrer must have $10,000 in lifetime trading volume before earning referral rewards. A referrer can share a market or profile link, and the referred user must sign up within 30 days of clicking. The page lists rewards of 10% of net fees from direct referrals and 5% from indirect referrals, for the first 30 days after signup or until the referred account reaches Platinum, whichever comes first. Because rewards are based on net fees, trading volume does not guarantee a referral reward; the page notes that not every market has fees. Check Polymarket’s referral-program terms.
Polymarket US referral incentive
A January 16, 2026 public filing by Polymarket US operator QCX LLC describes a separate 2026 incentive program effective February 2, 2026. It says a first-time user who uses a referral code, is successfully onboarded, and deposits at least $10 within 30 days is eligible for a one-time $10 account credit. The filing says incentive funds are applied as original margin on new positions and may be withdrawn upon position settlement or liquidation. It also allows the program and terms to be amended. The filing does not establish that this offer is currently available to every reader or in every jurisdiction, so check the current notice and account offer. Read the Polymarket US incentive filing.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why the individual promotion rules matter
General referral eligibility is not a substitute for a promotion’s own restrictions. Kalshi’s completed 2026 World Cup promotion, for example, required a valid KYC-approved account, age 18 or older, and U.S. physical presence; it excluded New York and Florida residents or people located there. Its entry window ran from June 4 until kickoff of the first match on June 11, 2026. That promotion has ended, and those limits should not be read as universal Kalshi referral rules. Its terms illustrate why you should check the exact offer rather than infer eligibility from a platform’s general FAQ. See the completed promotion’s official rules.
