A federal judge has issued a preliminary injunction preventing prediction market platform Kalshi from offering sports contracts on the lands of two California tribes. The decision, handed down by U.S. District Judge Jacqueline Scott Corley, marks a notable development in the ongoing clash between tribal gaming interests and emerging prediction markets.
Tribal Victory in California
The injunction follows a Ninth Circuit Court of Appeals decision that found the Blue Lake Rancheria and Chicken Ranch Rancheria of Me-Wuk Indians are likely to succeed in arguing that Kalshi’s sports contracts constitute Class III gaming under the Indian Gaming Regulatory Act (IGRA). The court rejected Kalshi’s claim that federal commodities law overrides IGRA on tribal lands. The order reverses an earlier decision from November 2025, which had denied the tribes’ request for an injunction. Now, Kalshi must receive maps from the tribes outlining land boundaries and report on its compliance within three weeks of the order.
This ruling could bolster other tribal legal actions against prediction markets, including ongoing cases in Wisconsin and New Mexico. It may also encourage additional tribes to pursue litigation to protect their gaming interests against similar platforms.
CFTC Orders End to Geographic Restrictions
In contrast to the California ruling, the Commodity Futures Trading Commission (CFTC) has directed federally regulated exchanges, including those offering sports and election contracts, to eliminate geographic restrictions within the United States. The agency argues that national, impartial access is required under the Commodity Exchange Act. Exchanges have 30 days to comply or must justify why they cannot.
This move sets up a potential regulatory conflict, as some court orders—including the new California injunction—require geofencing, while the CFTC insists on nationwide access. Similar disputes have occurred in states like Michigan and New York, with federal and state authorities sometimes issuing contradictory directives to prediction market operators.
Why This Matters for the Industry
The diverging actions of courts and regulators create uncertainty for operators, affiliates, and suppliers in the prediction market and gaming sectors. Operators like Kalshi face conflicting obligations that can impact their ability to offer services in certain jurisdictions. For tribal casinos, the ruling supports their authority over gaming on their lands, potentially setting a precedent for future disputes. Affiliates and suppliers must monitor these developments closely, as they affect market access, compliance requirements, and partnership opportunities.
Key takeaways
- A federal judge has blocked Kalshi from offering sports contracts on two California tribes’ lands.
- The CFTC has ordered exchanges to remove geographic restrictions, potentially clashing with court mandates.
- The California ruling may encourage more tribal legal action against prediction markets.
- Operators face growing regulatory uncertainty as state and federal requirements diverge.
