Kalshi Botches $18.6 Million Payout in Michigan Football Market

The prediction market Kalshi faced a major operational hiccup after it prematurely settled a Western Michigan versus Michigan football game. The exchange incorrectly declared Western Michigan the winner when the clock initially hit zero, leading to the payout of funds to the wrong users. Shortly after, officials added one second back to the game clock, allowing Michigan to score a touchdown and secure a 13 12 victory.

Following the final whistle, Kalshi scrambled to reverse the initial payouts. The exchange clawed back money from the wrongly declared winners and distributed the correct funds to those who backed Michigan. With $18.6 million in total volume moving through this specific market, the rapid swings in account balances left many traders confused.

This incident arrives at a difficult time for the platform, as it is currently fighting a court order that restricts it from offering sports contracts to Michigan residents. Critics of prediction markets are already pointing to the error as evidence of the risks involved in automated settlement processes for live sports.

While Kalshi corrected the payments within hours, the event raises questions about the protocols used to determine game outcomes. Investors and users will be watching to see if the exchange releases details on how the settlement rule failed and what steps it will take to prevent similar mistakes in future matches.
