Description

This market predicts which contestant will be officially declared the winner of Big Brother Season 28. The winner is announced during the season finale or through official channels immediately following.

Kalshi

Resolution requires official declaration of a winner during the finale or via official channels immediately after. If multiple joint winners are declared, each resolves to Yes with payouts split equally. If no winner is declared, all markets resolve to No. Winners who decline the award still count unless acceptance was a stated condition of victory. Disqualifications or withdrawals before the finale result in No resolution. The original finale announcement governs resolution; later title stripping does not affect the outcome. Secondary awards like fan favorite do not count as winning. For team or couple competitions, being part of the winning unit qualifies.
