Looking for an easy way to build your bankroll at Polymarket? Refer friends to the app to earn rewards!
Polymarket's refer-a-friend program is simple: invite friends using your referral code or invite link. When your friend signs up and deposits $10, both parties get a $25 reward.
My experience with Polymarket.us' refer-a-friend program was successful, as I maxed out the referral program's $350 cap. I'll walk you through all the details and show you how you, too, can take full advantage of this promo.
If you haven't signed up for Polymarket yourself yet, make sure you use our Polymarket referral code before you start inviting friends.

📋 Before You Refer: Polymarket Refer-a-Friend Checklist
Your Polymarket.us refer-a-friend code is valuable. So before you spend time getting your friends to sign up for this prediction market app, review these criteria to ensure you get credit for your referrals.
You:
- ✅ Are you an existing Polymarket user? If yes, you can refer. If no, sign up through our links first, then start referring.
- ✅ Is your identity fully verified? You won't be able to refer friends until you've completed KYC verification. Fully verify your identity before sharing your username or referral code.
- ✅ Have you got your referral link or code ready? You can share either your invite link or referral code. Your code is simply your Polymarket username — just make sure it's spelled right!
Your friend:
- ✅ Are they new to Polymarket? They can't have a previous Polymarket account; self-referrals and duplicate accounts can get both parties suspended.
- ✅ Can they deposit at least $10? Friends may overlook that the refer-a-friend offer requires a minimum deposit of $10. Make sure this happens so the bonus gets released to you and your friend.
- ✅ Can they verify their identity? No identity verification means no bonus.

👣 How to Refer a Friend to Polymarket in September 2026

I've tested both of these methods for referring friends to Polymarket:
- Sharing my referral code (username) with friends and having them enter it when registering
- Sharing my invite link, which friends click to sign up for a new account
Only existing users can share a referral code or link. If you're new to Polymarket.us, sign up using the ACTION promo code.
Here's a full breakdown of how to refer friends to Polymarket:
Sign Up to Polymarket First
You need account before you refer anyone yourself. Sign up with our Polymarket code ACTION by following these steps:
- Authenticate with your Google or Apple account.
- Choose a username that's simple enough to share with friends, as it will act as your unique referral code.
- Enter the ACTION promo code during registration.
- Verify your account by providing your full name, date of birth, and residential address. Polymarket may ask you to scan your ID and take a photo to verify it's you.
- Deposit $10 via ACH transfer, debit card, wire transfer, etc.
Now that you're signed up, you'll want to start referring friends.
Share Your Polymarket Referral Code or Link
You can invite a friend to trade on Polymarket in two ways.
- Unique link: On the Invite Friends screen in the app, you'll find a unique link you can share with friends via text message or social media.
- Code: Your username is your referral code. Your friend MUST enter your username during sign-up; once they pass that stage, they can't add it retroactively.
How Does Your Friend Qualify for the Polymarket Referral Bonus?
Sending your friend the Polymarket.us referral link is only half the battle. Make sure they follow these additional steps so both parties get the bonus credits they were promised.
- Your friend completes the sign-up form using the referral link or code you sent.
- Your friend clears KYC verification. They can't deposit or meet the referral's terms and conditions until KYC is complete.
- Your friend deposits at least $10 using their preferred banking method: debit card, ACH transfer, or wire transfer.
- Both you and the referee receive your $25 bonus credits after all steps are completed.
Refer Up to 14 Friends to Polymarket (Up to $350)
The refer-a-friend program at Polymarket.us does have limits. Each new user can only be referred once, and people with an existing account can only refer new users.
Each user can refer up to 14 people total ($350 total in referral bonuses).
I've completed 14 successful referrals myself, and while the $350 in credits is nice, I can no longer take advantage of this program. It would be nice to see Polymarket up the maximum reward amount going forward so that it better competes with Kalshi's refer-a-friend program.
Make sure you use your Polymarket refer-a-friend bonuses within 7-30 days of expiration. You can use your credits to trade on most qualifying markets, including Polymarket Combos.
🤔 Polymarket Referral Code Not Working? Troubleshooting
There's nothing more frustrating than waiting for a bonus to come through... and never seeing it. This section covers common issues that come up when referring friends to Polymarket:
- Your referral isn't a new user. Existing users aren't eligible for this bonus. And don't try to create duplicate accounts, as it violates the terms of service and you'll get banned.
- The code wasn't entered at signup. You must enter the code at the time of signup. No exceptions.
- Your referral hasn't deposited yet. The refer-a-friend deal requires the referee to deposit at least $10.
- You've hit the referral limit. You cannot refer more than 14 people with your link or referral code.
- One of the accounts is flagged. Contact support to ask why one of the accounts is flagged.
💎 What If I Don't Have a Friend to Refer Me to Polymarket?

If you're new to Polymarket and need a friend's code or link to sign up, you're in luck.
You should use code ACTION from Action Network.
This prediction market promo code is super easy to enter, and the welcome offer you get is actually more valuable than the standard refer-a-friend bonus. Instead of $25 on a $10 deposit, you get $50 — you're essentially doubling your reward simply by using code ACTION instead of your friend's code or link.
If you're feeling particularly generous, you'll share this code with your friend instead of your own link or code. Your friend will ultimately get the better reward.
But if you want a slice of the pie, and you're OK with your friend getting a smaller bonus, you should send them your own link or username to sign up with.
🦺 Responsible Trading & Polymarket's Refer-a-Friend
When you scan the Polymarket.us app interface, you won't see a "responsible trading" section or some of the controls required of sports betting operators. That doesn't mean that Polymarket.us isn't thinking about its users' safety, though.
Polymarket.us users can contact customer support and request account and position limits. The FCMs tied to Polymarket will then impose limits on the volume or dollar amount in a user's account to support responsible trading habits.
Those new to prediction markets and used to built-in protections can protect themselves by building responsible trading habits. That includes practices like:
- Only trade with what you can afford
- Bonus credits are promotional credits and should not be treated as cash
- Trade on markets you have an understanding of
Friends you refer to Polymarket.us, especially if they're not familiar with prediction market trading, should be reminded that Polymarket.us functions more like a financial exchange, where limits are mostly self-imposed. Preparing your referees for what to expect will help them feel comfortable fulfilling the referral terms and starting to trade on their own.
