Polymarket Referral Code SIBONUS: Unlock Up to $350 in Bonuses

Use the latest Polymarket referral code SIBONUS when you sign up to claim a $20 welcome bonus, then earn up to $350 in referral credits by inviting friends to Polymarket US.

Deposit at least $10 to qualify for the welcome offer, then open Invite Friends in the Polymarket US app to find your referral link and username-based referral code. With the Polymarket referral bonus, you can earn a $25 bonus credit per qualifying referral, up to 14 times.

Sign up with the Polymarket promo code SIBONUS, and the referral program rewards both you and whoever you refer.

When a friend registers with your username or invite link, successfully completes onboarding, and deposits at least $10, you each receive a $25 bonus credit. The current Polymarket Refer-A-Friend terms list no additional trading-volume requirement before awarding the credit, making this one of the most straightforward referral programs in the prediction market industry.

Here is a quick look at how the Polymarket referral bonus works.

Getting access to your Polymarket referral code is easy. Start by clicking any of our verified links on this page, then enter the latest Polymarket code SIBONUS during registration to claim the Deposit $10, Get $20 Bonus welcome offer.

Once your account is registered and verified, open Invite Friends in the Polymarket US app, one of our top prediction market apps for real-world and sports traders. Once registered on Polymarket, your username automatically serves as your referral code, and the app also provides a personalized invite link you can share with friends. Polymarket’s current consumer referral terms do not list a separate trading-volume requirement to access or share your code.

It is important to distinguish between the two codes:

• SIBONUS is the promo code you use to claim your own new-user welcome offer.
• Your Polymarket username is the referral code you share with friends after creating your account.

Here is a more complete breakdown of the steps to follow.

1. 📝 Register

Click through to Polymarket using one of the verified links on this page and create your account.

Enter the promo code SIBONUS when prompted during registration to qualify for the welcome offer. You will also need to complete Polymarket’s identity verification process before you can deposit funds, begin trading, and access all available account features.

2. 💳 Deposit at least $10

Once your account is verified, deposit at least $10 to qualify for the SIBONUS welcome offer.

The deposit is tied to the welcome promotion, not the availability of your referral code. Polymarket’s current referral terms do not state that you must deposit or complete a specific amount of trading before you can access the Invite Friends section.

Review the promotion displayed during registration to confirm the current qualifying requirements before funding your account.

3. 👤 Find your Polymarket referral code

To get your Polymarket referral code, open the Polymarket US app and select Invite Friends.

Your Polymarket username is your personal referral code. You will also find a unique invite link that you can copy or share via text message or another supported app.

You don't need to generate a separate code or wait for Polymarket to assign one. Once you set up an eligible account, you can start sharing your username or invite link with new users.

Once you have found your Polymarket referral code and invite link, referring a friend on Polymarket involves four main steps: share your link or username, have your friend apply it during registration, ensure they complete verification, and have them deposit at least $10.

You and your friend will each receive a $25 bonus credit after Polymarket confirms that all qualifying requirements have been completed.

1️⃣ Share your Polymarket referral link or username

Open Invite Friends in the Polymarket US app and copy your personalized invite link.

Send the link to your friend by text message or another messaging service. You can also give them your exact Polymarket username to enter manually as their referral code.

Using the invite link is generally the simplest option because it reduces the risk of entering your username incorrectly.

2️⃣ Your friend creates and verifies a new account

Your friend must be a new Polymarket US user.

They should open your invite link or enter your username in the referral field during registration, then complete Polymarket’s onboarding and identity verification process.

Apply the referral code during sign-up. Polymarket generally will not add a forgotten code after you've created an account.

3️⃣ Your friend deposits at least $10

After successfully completing onboarding, your friend must deposit a minimum of $10.

Creating and verifying an account without making the qualifying deposit will not complete the referral requirements.

4️⃣ You both receive a $25 bonus credit

Once Polymarket verifies that your friend has completed all qualifying steps, you each receive a $25 bonus credit and are ready to use one of the best NFL prediction market apps.

You can earn up to 14 referral bonuses, giving you the opportunity to collect as much as $350 in Polymarket credits.

The reward is trading credit, not cash you can withdraw. You must use the credit to place a trade first. Once that trade settles or you close the position, the resulting funds or profits become withdrawable cash in your Polymarket account.

Both the existing user and the referred friend must satisfy Polymarket’s eligibility and account requirements.

Here are some key terms to keep in mind when claiming the Polymarket referral code:

• The referrer (existing user) must have an eligible Polymarket US account: Your username serves as your code, and your invite link appears in the app.
• The friend must be a new user: Someone who already has a Polymarket US account cannot be attached as a new referral.
• The code must be applied during registration: Your friend must use your link or enter your username before completing sign-up.
• The friend must complete onboarding: They must satisfy Polymarket’s identity verification and account eligibility requirements.
• The friend must deposit at least $10: This is the qualifying deposit under the current consumer offer.
• Only one bonus is permitted per verified identity: A new user cannot qualify more than once by creating additional accounts.
• Each new user can only be referred once: Multiple existing users cannot claim a bonus for the same new customer.
• The referrer can earn up to 14 bonuses: The standard program stops awarding additional referral credits after the limit has been reached.
• Self-referrals are prohibited: You cannot refer yourself or another account that you own or control.
• Fraudulent referrals can be disqualified: Polymarket may withhold or claw back credits and suspend accounts involved in abuse.

Polymarket gives you two different opportunities to add promotional credit to your account: a welcome offer when you first register and a fixed reward for each qualifying friend you refer afterward.

The key is to treat them as separate stages. Use SIBONUS to set up your account, then switch to your Polymarket username and invite link when you are ready to take advantage of the Polymarket referral program and refer new users. Unlike programs that base rewards on a friend’s trading volume, the Polymarket US referral offer pays a set $25 credit per successful referral.

Here is the most effective way to approach the two offers:

1. Redeem the welcome offer: Enter the code SIBONUS, deposit at least $10, and complete the qualifying requirements to receive the $20 welcome bonus. Make sure the code is attached before you finish registering.
2. Find your referral tools: After you create and verify your account, open Invite Friends in the Polymarket US app. Your username is your referral code, and Polymarket also provides a personalized invite link that you can send directly to friends.
3. Share the link before your friend signs up: Referral tracking must be established during registration. Sending the personalized link is generally the safest option because it reduces the chance of entering your username incorrectly or leaving it off the account.
4. Make sure each friend completes the deposit requirement: A friend must be a new Polymarket US user, finish onboarding, and deposit at least $10. Once Polymarket approves the referral, you each receive a $25 bonus credit.
5. Work toward the 14-referral limit: Polymarket allows you to earn up to 14 standard referral bonuses. That puts as much as $350 in referral credits within reach, in addition to the $20 welcome bonus available when you first join.

⚠️ The biggest mistake to avoid is waiting until after a friend has registered to send your code. Polymarket generally doesn't add referrals retroactively, so you need to apply the invite link or username before the new account is completed.

The Polymarket US Refer-A-Friend program offers a straightforward fixed reward for both users.

Its $10 deposit requirement makes the offer relatively accessible, but the credits aren't equivalent to unrestricted cash, and the code must be applied during registration.

Pros

✅ Both users receive a $25 credit

The existing user and new customer receive equal rewards after all requirements are completed.

This creates a clear benefit for both sides of the referral.

✅ The minimum deposit is only $10

Your friend must deposit at least $10 to qualify.

The current published requirements do not include an additional trading-volume threshold before the referral reward is issued.

✅ Your username is your referral code

There is no separate code to generate or find.

Your Polymarket US username serves as your referral code, and the app also provides a personalized invite link.

Cons

✖️ The code cannot be added after sign-up

Your friend must use your invite link or manually enter your username while registering.

If they forget, Polymarket generally will not attach the referral retroactively.

✖️ Referrals are capped at 14

You cannot continue earning $25 indefinitely after reaching the $350 maximum, which is lower than that of some other competitors.

Polymarket is not the only prediction market with a consumer refer-a-friend offer.

If you're torn between prediction markets and sports betting, you can take advantage of both. Our Kalshi referral code guide explains how Kalshi’s program works, including its registration, verification, and trading requirements.

Here are some other prediction market apps with referral programs:

• Crypto.com – The Crypto.com referral code is a milestone-based referral structure paid out in its native CRO token. Both parties can unlock up to $50 on the mobile app or up to $2,000 on the exchange, depending on the new user's trading and staking volume.
• OG.com – When you claim the OG promo code, the referrer (current user) and the new user can earn up to $150 each in trading bonuses, unlocked progressively based on the friend's 30-day trading milestones.
• ProphetX - The ProphetX promo code lets you get started on the platform with the welcome offer and use the referral program, which offers a 'Give $25, Get $25' refer-a-friend offer.
