A newly disclosed CFTC rulemaking, a $36 billion New York lawsuit and a resolved circuit split all surfaced this week in the prediction-market operator's expanding legal fight.
Kalshi's legal position sharpened on multiple fronts this week. The Ninth Circuit ruled unanimously on August 28 that the Commodity Exchange Act likely does not preempt Nevada's gaming regulations as applied to Kalshi's sports event contracts, a decision that directly contradicts an April Third Circuit ruling that told New Jersey it lacked authority to regulate Kalshi. A CFTC spokesman said the Ninth Circuit's ruling "has now teed up a circuit split that calls out for resolution by the Supreme Court." A separate Fourth Circuit case involving Maryland remains pending.
Underneath that litigation sits a regulatory process that hasn't drawn as much attention: the CFTC proposed in June to replace its blanket prohibition on gaming-linked contracts with a case-by-case public-interest review. Under the proposed framework, sports contracts would still be classified as gaming, but most game-outcome and proposition contracts would be permitted. Kalshi Chief Executive Tarek Mansour said a final rule is expected "in the next few weeks or the next few months," and the company's head of litigation, Jovy Dedaj, has argued that the Ninth Circuit's ruling "rests, in large part, on an incorrect interpretation of the CEA's Special Rule." Kalshi's own strategy for a Supreme Court petition leans on that rulemaking landing in its favor before or during the justices' consideration of the case.
New York Attorney General Letitia James sued Kalshi on July 31, alleging the company operates as "an unlicensed gambling operation" and seeking to halt its event contracts nationwide across eight separate charges, with more than $36 billion in damages sought. The CFTC separately invoked emergency powers requiring Kalshi to keep trading "in accordance with the core principles of a designated contract market" while the litigation proceeds. CFTC Chair Michael Selig characterized the New York suit as an attempt to "prematurely stifle this market" through state gambling law before a court has issued a final ruling.
That's now five distinct state-level fronts in Kalshi's fight over the past several months, spanning New Jersey, Nevada, Arizona, Maryland and now New York, the largest in stated stakes by a wide margin.
The regulatory rulemaking is the detail investors and competitors should be watching most closely. Court rulings resolve one jurisdiction at a time; a finalized CFTC rule reclassifying most sports and event contracts would apply everywhere at once, and Kalshi's own leadership has said its Supreme Court strategy depends on the rule's timing and substance. A prediction-market operator's entire regulatory future increasingly hinges less on how nine justices eventually rule than on how one federal agency, moving on its own clock, decides to write a rule it proposed months ago.
