What happened

The Sixth Circuit rejected Kalshi’s argument that complying with state gambling laws would conflict with its duties as a federally regulated exchange, according to [CryptoSlate](https://cryptoslate.com/kalshi-must-lock-out-state-users-after-major-court-loss). Its headline says Kalshi must lock out state users, while the supplied account says the court identified geofencing as a workable means of compliance.

[The Block](https://www.theblock.co/news/regulation/2026-09-26-kalshi-loses-appeal-over-ohio-and-tennessee-sports-betting-laws-widening-circuit-split-416937) reports that Kalshi had not adequately shown its sports contracts were swaps under the Commodity Exchange Act. That account also says the decision widened a circuit split.

Why it matters

The ruling puts access to Kalshi’s sports contracts in Ohio and Tennessee in question. The reported geofencing discussion suggests a way to comply with both state rules and federal exchange duties, but the supplied record does not establish what access changes Kalshi has made.

[Cointelegraph](https://cointelegraph.com/news/kalshi-loses-appeal-setting-up-potential-supreme-court-case) says the loss could lead to a Supreme Court case. That remains a possibility rather than a reported next step.

What to watch

Watch for Kalshi’s response, any change to access in Ohio or Tennessee, and any filing seeking further review.
