The Ninth Circuit Court of Appeals recently ruled in the case of Blue Lake Rancheria v. Kalshi, Inc. (No. 25-7504), affecting the rights of two federally recognized tribes in California. The court's decision addresses the legality of event contracts offered by Kalshi, Inc., which the tribes argue are essentially sports bets. This ruling is significant as it impacts how online betting operates on tribal lands, potentially altering the landscape of gaming rights for Native American tribes.

The case arose from a dispute between the Blue Lake Rancheria and the Chicken Ranch Rancheria of Me-Wuk Indians against Kalshi, Inc., and Robinhood Markets, Inc. The tribes claimed that Kalshi's event contracts, which pay out based on the outcomes of sports events, violate the Indian Gaming Regulatory Act (IGRA) and the Lanham Act. They argued that these contracts should be classified as class III gaming activities, which require tribal authorization under IGRA.

The dispute escalated when the tribes sought a preliminary injunction to stop Kalshi from offering these contracts on their lands. The district court initially denied the tribes' motion, stating that Kalshi was not bound by tribal regulations and that the Unlawful Internet Gambling Enforcement Act (UIGEA) governed the situation. The tribes appealed this decision, leading to the recent ruling by the Ninth Circuit.

The Ninth Circuit's ruling reversed the district court's denial of the preliminary injunction in part, affirming that the tribes were likely to succeed in their claims against Kalshi. The court found that Kalshi's event contracts likely constituted class III gaming activities under IGRA. Judge M. Margaret McKeown, writing for the panel, stated, "The substance of the sports event contracts offered on Kalshi’s DCM is sports gambling, regardless of whether Kalshi calls them swaps." This determination is crucial as it emphasizes that the nature of the activity, rather than its label, dictates its classification under the law.

The court also clarified that the IGRA is not displaced by the UIGEA, which pertains to illegal internet gambling. The Ninth Circuit concluded that IGRA provides a cause of action for tribes to enjoin class III gaming activities conducted improperly on Indian lands. The court's opinion highlighted that the event contracts were likely located on Indian lands because users entered into them while situated on tribal territory.

Furthermore, the ruling indicated that Kalshi's contracts were offered in violation of the tribes' secretarial procedures, which require that class III gaming be conducted only with tribal authorization. The court remanded the case back to the district court to evaluate the remaining factors for granting a preliminary injunction.

This ruling has significant implications for the future of online betting and gaming rights for Native American tribes. It reinforces the authority of tribes to regulate gaming activities on their lands and clarifies the legal definitions surrounding online betting products. The decision may set a precedent for how similar cases are handled in the future, particularly as the landscape of gaming continues to evolve with the rise of online platforms.

The case also highlights the ongoing tension between state and tribal regulations regarding gaming. As more states legalize sports betting, the question of how these laws interact with tribal sovereignty and rights under IGRA becomes increasingly relevant. The Ninth Circuit's ruling reaffirms the importance of tribal authority in regulating gaming activities, especially in the context of new technologies and business models.

Looking ahead, it remains to be seen whether Kalshi will appeal the Ninth Circuit's decision. The case could also influence other pending cases involving online gaming and tribal rights, as it addresses fundamental questions about the intersection of federal, state, and tribal laws.

Overall, the Ninth Circuit's ruling in Blue Lake Rancheria v. Kalshi, Inc. marks a significant moment in the ongoing dialogue about gaming rights and the sovereignty of Native American tribes. As the legal landscape continues to shift, this case will likely serve as a critical reference point for future disputes involving gaming on tribal lands.
