Once you complete your first real-money trade on any eligible market, including predictions tied to the Texas vs. Oklahoma game, your $25 bonus will be credited to your account. If your trade on the Texas vs. Oklahoma matchup wins, you keep your profits after meeting the 1x playthrough requirement. If your trade loses, you can use your bonus funds to place additional trades across sports, politics, and other markets.

Key terms and conditions for this offer include the following:

You no longer need an invitation to create a Polymarket account, as the U.S. waitlist has been removed for eligible users. The promo code SIBONUS is different from referral links and must be entered during the registration process. Once your account is created, you cannot apply the code retroactively, so enter it at sign-up.

Follow these steps to register, deposit, and place your first trade on the Texas vs. Oklahoma game to claim your $25 bonus.
