Deposit $10, Get $20 Bonus
Here's how to claim your $20 bonus and start trading on Polymarket today.
The Polymarket invite code is entered during the account registration process. New users should launch the Polymarket app using a verified promotional link, then enter SIBONUS when prompted during sign-up. Once your account is verified and you've completed the qualifying deposit and trade, your bonus will be credited automatically.
The regulated Polymarket US app is now available to eligible users on both iPhone (iOS) and Android, allowing you to trade prediction markets on sports, politics, finance, crypto, entertainment, and other real-world events from your mobile device. Unlike the early rollout, Polymarket is no longer invite-only, so eligible U.S. users can register immediately without joining a waitlist.
