Key Moments:
- A United States District Court judge denied a preliminary injunction sought by three California tribes against Kalshi.
- The ruling cited federal oversight of Kalshi’s contracts under the Commodity Exchange Act and Commodity Futures Trading Commission.
- The tribes intend to continue their legal efforts as the broader lawsuit proceeds.
Court Ruling Upholds Kalshi’s Operations
Kalshi has received significant legal support after Judge Jacqueline Scott Corley of the Northern District of California denied a request from three California tribes to halt its sports-related contracts from operating on tribal lands. The Blue Lake Rancheria, the Chicken Ranch Rancheria of Me-Wuk Indians, and the Picayune Rancheria of the Chukchansi Indians asserted that such contracts equate to illegal Class III gaming under the Indian Gaming Regulatory Act (IGRA), and accused Kalshi of misleading claims about the legality of sports betting under the Lanham Act.
Judge Corley found there was insufficient evidence to favor the tribes’ positions at this stage. Addressing the advertising complaint, she explained that Kalshi’s statement, “sports betting is legal in all 50 states,” could be considered an opinion, complicating any Lanham Act pursuit.

Federal Oversight and Regulatory Arguments
The judge noted that, while the Unlawful Internet Gambling Enforcement Act (UIGEA) does apply to online gambling that crosses state and tribal boundaries, Kalshi’s sports event contracts fall within the jurisdiction of the Commodity Exchange Act (CEA) and thus under the regulation of the Commodity Futures Trading Commission (CFTC). According to the ruling, this regulatory structure means current gambling laws do not prohibit Kalshi’s activities.
| Party | Argument | Judge’s Response |
|---|---|---|
| California Tribes | Claimed Kalshi’s contracts are illegal Class III gaming under IGRA; accused Kalshi of false advertising under Lanham Act | Denied; advertising seen as opinion, and Kalshi’s contracts governed by CEA/CFTC |
| Kalshi | Positioned its offerings as federally regulated financial products, not traditional gambling | Ruling accepted federal oversight and allowed operations to continue |
Ongoing Dispute and Industry Implications
Although the decision represents a win for Kalshi at this early phase, Judge Corley recognized concerns regarding tribal sovereignty and the potential for federal regulation to circumvent existing interstate gambling restrictions. She clarified, however, that such concerns could not override the statutory limitations on the court’s authority.
Legal analysts observe that this case demonstrates how prediction markets are pushing the boundaries between financial products and covered gaming activities. Kalshi expressed satisfaction with the outcome, emphasizing its compliance with federal regulations rather than acting as a standard gambling operator. The tribes reaffirmed their intention to keep challenging Kalshi as the case progresses in federal court.
