Kalshi incorrectly settled a college football market after Michigan appeared to lose to Western Michigan, distributing winnings before the game’s final result had been properly resolved.
A last-second pass changed the result
Western Michigan led Michigan by one point when the clock reached zero on Saturday. However, Michigan quarterback J.J. Buchanan completed a long Hail Mary pass as time expired, producing a dramatic upset reversal.
The play would not have counted under NFL timing rules, but NCAA has different rules regarding game time. Officials ruled the touchdown was valid, giving Michigan the win after the apparent end of the game.
Millions in market activity affected
Kalshi had already treated Michigan as the losing side and paid users who had wagered against the team. The platform then reversed that decision after the official result became clear.
Marshall Cohen reported on September 6, 2026, that Kalshi acknowledged the premature settlement. The company reclaimed the incorrect payouts, reimbursed the users who had initially lost and then paid the correct winners. The market recorded $18.6 million in trading volume.
Users whose initial winnings were removed were also given a $50 credit. Although that approach corrected the market’s final outcome, reversing payments after the event created another layer of uncertainty around how these contracts should operate.
Regulatory questions remain
The dispute is particularly sensitive because Kalshi presents itself as a speculation market rather than a conventional sports-betting service. That distinction is being tested as platforms of this type expand into sporting events and face growing scrutiny from regulators and courts.
Several states began preparing challenges to sports-related prediction markets during the summer. Michigan was already seeking to restrict Kalshi: in July, Judge Rosemarie Aquilina ordered the platform to block sports betting in the state.
Just a mere two days before the game, Aquilina described Kalshi as a “sports betting operation masquerading as an investment opportunity”. Her order required the company to pay $500,000 for each additional day it remained accessible in Michigan.
The legal status of prediction markets is still developing, but this incident highlights a practical problem beyond regulation: a platform can face immediate financial and customer-service consequences when it settles a close game before the result is final.
