This event is for the WBB game between Colorado State Rams and Michigan State Spartans on March 20 at 7:30 PM ET.
If the game is postponed, this market will remain open until the game has been completed.
If the game is canceled entirely, with no make-up game, this market will resolve 50-50.
Kalshi resolves YES for either team winning (both outcomes trigger YES), while Polymarket resolves to a categorical outcome naming the winner. This creates fundamentally different market structures: Kalshi is a binary YES/NO market that always resolves YES, whereas Polymarket is a winner-determination market.
Hero Tip:
Do not treat these markets as equivalent. On Kalshi, you are betting that the game will be played and completed (always YES). On Polymarket, you are betting on which specific team wins. If you want directional exposure to a team victory, use Polymarket. If you want to hedge game postponement/cancellation risk, Kalshi offers no such protection.
Critical Divergence Points:
Kalshi:
Outlier: Resolves YES if Michigan State wins OR if Colorado State wins. Both possible game outcomes trigger YES resolution, making this a market on game completion rather than team selection. Key quote: 'If Michigan St. wins... then the market resolves to Yes. If Colorado St. wins... then the market resolves to Yes.'
Polymarket:
Outlier: Resolves to a categorical outcome naming the winning team ('Colorado State Rams' or 'Michigan State Spartans'), with explicit handling for postponement (market remains open) and cancellation (50-50 split). Key quote: 'If the Colorado State Rams win, the market will resolve to Colorado State Rams. If the Michigan State Spartans win, the market will resolve to Michigan State Spartans.'
