Polymarket is offering a $25 trading bonus for Buffalo vs. Minnesota Monday Night Football on Monday, November 9 through the promo code SIBONUS.
The offer is tied to account registration and requires a $10 deposit. After that deposit is made, the $25 trading bonus becomes available after the first real-money trade on an eligible market.
What the promo includes
The key detail for readers is simple: SIBONUS unlocks a $25 bonus, but it is not automatic. The promotion only activates after the deposit requirement is met and the first eligible trade is completed. It is also subject to standard risk and eligibility terms, including jurisdiction restrictions and a trading risk warning that includes the possibility of a 100% loss.
Where it is available
The promotion is available only in eligible jurisdictions. That means access is limited, and users must meet the platform’s requirements, including being 18+ and completing the necessary registration steps before the bonus can be used.
For Buffalo vs. Minnesota, the timing is the main hook. The offer is specifically attached to Monday Night Football on Monday, November 9, making it a matchup-specific promotion rather than a general sitewide deal.
