Federal judge bars Kalshi sports contracts on lands of California tribes suing it

The preliminary injunction turns Kalshi's voluntary location blocks into a court order. It covers the plaintiff tribes' lands only, not the rest of California.

US District Judge Jacqueline Scott Corley on 4 November 2026 granted a preliminary injunction barring Kalshi Inc. and KalshiEX from offering sports contracts on the Indian lands of the tribes suing them in the Northern District of California. Kalshi must report to the court on its compliance within 21 days, which falls on 25 November.

The one-page order covers any sports contracts, including those that reference baseball, tennis, pickleball, soccer, basketball, football, golf, chess, esports, hockey, motorsports, boxing, wrestling and UFC events. The tribes must give Kalshi maps of their lands by 13 November. The order sets no delayed start and names no blocking technology, and it gives no reasons beyond a status conference held that day.

The order follows a 16 September Ninth Circuit ruling for Blue Lake Rancheria and Chicken Ranch Rancheria of Me-Wuk Indians. The panel found them likely to succeed on their claim that a customer buying a Kalshi sports contract while on tribal land is engaging in Class III gaming there under the Indian Gaming Regulatory Act, and it sent the case back to Judge Corley. A third tribe, Picayune Rancheria of the Chukchansi Indians, was dismissed from that appeal by agreement, and the tribes moved to add Buena Vista Rancheria as a plaintiff, which the October status report says the defendants did not oppose. We could not confirm the current plaintiff list.

In an October status report, Kalshi argued that an injunction was moot because it had worked with GeoComply to geofence the tribes' lands. The tribes disputed that the blocks work, saying a trade was placed from their land; Kalshi said it was looking into the report. Robinhood is also a defendant, and the tribes said they planned new claims against it, but the order names only Kalshi. We found no Kalshi statement on the order and no notice of appeal.

“Kalshi Inc. and KalshiEX (together, “Kalshi”) are enjoined from offering on the Tribes’ Indian lands any sports contracts”

Who this affects

People trying to trade Kalshi sports contracts while physically on the plaintiff tribes' lands in California. The order does not cover the rest of the state or Kalshi's non-sports contracts.
