Key Moments
- Native American tribes and 10 tribal associations submitted an amicus brief opposing Kalshi’s preliminary injunction request in Arizona.
- The brief argues that Kalshi’s unlicensed gaming operations on state and tribal lands undermine tribal regulatory authority and revenue.
- Arizona filed criminal charges against Kalshi’s parent companies, citing illegal gambling activities without a license.
Tribal Groups Respond to Kalshi’s Legal Motion
A group of Native American tribes and 10 tribal associations, including the Indian Gaming Association, formally sided with Arizona in the ongoing lawsuit involving prediction market operator Kalshi. They filed an amicus brief urging the court to deny Kalshi’s request for a preliminary injunction. This sets the stage for a high-stakes hearing.
The brief, drafted by leading tribal gaming attorneys, warns that siding with Kalshi could disrupt established legal frameworks. In particular, it could affect decades of state, tribal, and federal oversight in Arizona’s gaming sector.
Arguments Asserting Tribal Sovereignty
The brief states, “Kalshi asks this Court to override the unique tribal-state regulatory structure of sports betting in Arizona. It seeks to abandon national policy on tribal-state regulation and turn decades of federal law upside down. The Court should not do so.”
Tribes claim that Kalshi has operated without proper approvals. They argue that the company diverts crucial revenues from tribal and state governments, threatening tribal economic independence. “Kalshi, without any licence or approval, brazenly entered state and tribal lands to conduct unregulated gaming. In doing so, it siphons vital revenue into its owners’ pockets. For tribes, gaming is existential, not just commercial.”
The filing cautions that a ruling in favor of Kalshi could destabilize Tribal-State Gaming Compacts in Arizona. These compacts maintain a careful balance of economic and regulatory interests between tribes and the state.
Additionally, the brief challenges Kalshi’s reliance on federal commodities laws, arguing that its interpretation of the Commodity Exchange Act conflicts with established U.S. gambling regulations.
Escalating Legal and Regulatory Pressures
The court hearing comes amid growing scrutiny of Kalshi by state law enforcement and regulatory bodies. Two weeks ago, The Wall Street Journal reported that Arizona filed criminal charges against Kalshi’s parent companies for running an illegal gambling operation without a license.
Arizona Attorney General Kris Mayes said the company accepted bets on sports, elections, and other events in violation of state law. This law prohibits unlicensed wagering and bans election betting.
Kalshi rejected the allegations, calling them “seriously flawed” and describing the case as legal maneuvering. Regulators, including the Commodity Futures Trading Commission (CFTC), are closely watching. CFTC Chair Michael Selig described it as a jurisdictional conflict.
Broader Industry Developments and Enforcement Actions
The prediction markets industry, including companies such as Polymarket, has grown rapidly. However, recent months have brought increased regulatory attention. Platforms faced criticism for offering markets tied to geopolitically sensitive topics, raising questions about legal oversight.
States like Massachusetts and Michigan have moved to curb unlicensed operations through legal action or stricter regulation.
Kalshi responded with legal challenges against multiple states, including Arizona, Iowa, and Utah. The company asserts its contracts fall under federal commodities law. Still, federal courts in Ohio and Nevada ruled against Kalshi’s attempts to block state regulations. Appeals remain ongoing.
