Polymarket invite code: how to get one and what you get
Polymarket doesn't require invite codes for signup — anyone in an eligible jurisdiction can create an account directly. Here's what 'invite code' actually means, what referral codes do, and whether there's a bonus.
Does Polymarket require an invite code?
No. Polymarket is an open platform. Anyone in an eligible jurisdiction can sign up directly at polymarket.com with an email or a crypto wallet. There is no gating behind invite codes.
People asking about "Polymarket invite code" usually mean one of three things:
- Referral link — a URL parameter that attributes a signup to a partner (like Prediction Markets 101).
- Promo code — a time-limited marketing code Polymarket has occasionally issued.
- Bonus code — implied expectation of a signup bonus.
Polymarket does not currently offer persistent signup bonuses. Referral links are the closest thing to an "invite code" system.
What referral links do
When you sign up via a referral link like polymarket.com/?r=allmarkets, Polymarket credits the signup to the referrer (us, in this case). The referrer earns a share of the fees you pay on trading activity — this is the Polymarket Affiliate Program.
For the referred user:
- No cost — trading fees and gas are identical
- No bonus unlocked (currently)
- No restrictions on how you use the account
For the referrer:
- Earn 30% of trading fees from referred users, for 180 days
This revenue is what funds independent coverage like ours. Using our referral link supports the site without costing you anything.
Polymarket's occasional promotions
From time to time, Polymarket has run time-limited promotions:
- Fee rebates during high-volume periods
- Trade-to-earn programs that reward active traders with a small USDC bonus
- Specific market promotions for launch events (e.g., a new sports contract launching with a liquidity rebate)
These are not persistent. Check Polymarket's official channels (Twitter, blog) for any current promotions. Third-party "invite code" pages promising bonuses are typically misleading or scams.
US users and invite codes
If you're a US resident, no invite code or referral link will let you sign up for Polymarket. The platform blocks US IPs regardless of any URL parameter.
For US residents looking for prediction markets, Kalshi is the legal alternative. Kalshi's referral program works similarly to Polymarket's — see Kalshi referral code for the details.
How to use a referral link correctly
- Click the link before signing up. The referral credit is attributed based on the URL you arrive via. If you sign up through the plain homepage, no referral attribution happens.
- Complete signup in the same browser session. Some users open the link, browse, and later return via a direct URL. The referral attribution can be lost in that case.
- Don't clear cookies before finishing signup. Polymarket's referral tracking uses cookies to attribute between click and signup.
If you signed up without a referral and want to support the site, there's nothing to be done after the fact — attribution is at signup only. You can always use our Kalshi referral if you're a US resident.
What about "free" or "bonus" invite codes?
You may see ads or YouTube videos offering "free Polymarket invite codes with $50 deposit bonus" or similar. Be skeptical.
- If it's a code distributed by Polymarket officially, it would be posted on their Twitter or blog. Cross-check.
- If it's from a random third-party website, it's likely marketing pretense — clicking the "code" link is just a referral URL dressed up as something special.
- If it requires you to enter a code, then deposit, then enter another code — it's a scam or a phishing attempt.
The clean path: go to polymarket.com (or via our referral link), sign up normally, deposit when ready. Avoid any "invite code" process that adds complexity.

Comparing Polymarket vs Kalshi on signup perks
Neither platform is aggressive with signup bonuses in the sense of "deposit $100 get $50 free". Both have referral programs that pay partners:
- Polymarket: 30% fee share, 180 days, no direct bonus for new users
- Kalshi: Occasional deposit credits or fee rebates for new users; referral program for partners
Kalshi has been slightly more active with new-user promotions. Check our Kalshi referral code page for current terms.

Is there a signup bonus for Polymarket?+
Not persistently. Polymarket has run occasional promotions during launches or high-volume periods. Check official channels for current offers. Third-party "bonus" claims are usually misleading.
