Kalshi Amps Up Legal Fight With New Montana Lawsuit

Kalshi is suing Montana to prevent it from enforcing gambling laws, arguing that its federally regulated exchange falls outside state jurisdiction. Kalshi contends that Montana singled out its prediction markets, despite having reached an accord not to take legal action against each other.
The request for a court injunction was filed against the state’s attorney general, Austin Knudsen, following the issuance of a cease-and-desist order claiming that the contracts offered by Kalshi amounted to illegal gambling activities under Montana laws. This case underscores a wider conflict between regulators at both the state and federal levels and those running prediction markets.
At the center of the case is whether Kalshi's event contracts should be treated as financial derivatives or traditional wagers. It's a question being posed about prediction market apps in multiple jurisdictions.
Kalshi maintains that its products fall under the Commodity Exchange Act, which grants the Commodity Futures Trading Commission (CFTC) exclusive authority over derivatives markets. It also argues that event contracts function as risk-management tools traded between participants, with pricing determined by market activity rather than a house edge.
State regulators have taken a different view. They argue that, regardless of the structure put in place, the contracts resemble sports betting contracts. Therefore, they should be governed by the state using licensing laws, taxes, and consumer protection.
In court, the claim has risen even higher, reaching constitutional proportions. Kalshi relies on the Supremacy Clause of the Constitution, which states that federal law prevails over any conflicting state law. The counterclaim is that what Kalshi does resembles gambling and not a financial instrument.
Kalshi argued in court that inaction may lead to restrictions from Montana and cause financial losses, as well as damage the company's reputation. This could shape how other states respond to such claims in the future.
Arizona ruling strengthens federal position
The Montana case follows a significant federal court decision in Arizona that has added momentum to Kalshi's position. A US District Court judge issued a temporary restraining order preventing Arizona from pursuing criminal charges against the company, siding with arguments presented by federal regulators.
The CFTC said the ruling blocks states from using criminal law against federally regulated exchanges offering event contracts. The agency emphasized that such enforcement attempts conflict with its exclusive authority over derivatives markets.
Federal officials framed the decision as a warning against state overreach. The ruling halted a case in which Arizona accused Kalshi of operating an illegal gambling business and facilitating bets on election outcomes. Kalshi disputed these claims and once again asserted that its platform was entirely distinct from sports betting sites and casino operations.
Arizona authorities supported their position by emphasizing that states could regulate their own sports gambling operations. This particular case marked the first time a state had charged Kalshi with criminal conduct.
