# Escalating legal and regulatory challenges for Kalshi > Live situation record from CLSTR: https://clstr.news/situations/2026-surge-in-predictionmarket-regulation-hits-brazil-and-the-united-states > Updated: 2026-09-08T16:38:13.000Z. Sources: 477. Developments: 137. Kalshi faces intensifying legal and regulatory pressure as state and federal authorities challenge its business model. While the company maintains its markets are financial instruments under CFTC oversight, a unanimous 3-0 ruling by the Ninth Circuit Court of Appeals has determined that its sports event contracts are likely sports bets rather than federally regulated swaps. This decision allows states to enforce gaming laws against the platform and creates a judicial split with the Third Circuit. To resolve this jurisdictional conflict, New Jersey has petitioned the U.S. Supreme Court to determine whether prediction markets should be regulated as gambling by states or as financial derivatives by the CFTC. New Jersey is specifically seeking to overturn a Third Circuit decision that favored Kalshi. Attorney General Jennifer Davenport argues that the Commodity Exchange Act does not grant the CFTC exclusive authority to override state police powers regarding gambling, consumer protection, and age restrictions. A Supreme Court ruling would establish a major precedent: if classified as gambling, platforms must secure individual state licenses and comply with state taxes; if classified as swaps, they remain under federal CFTC oversight. In Michigan, an Ingham County Circuit Court judge issued a preliminary injunction requiring Kalshi to use geofencing to block residents from accessing sports event contracts, citing concerns that the platform allows 18-year-olds to participate when state law requires users to be at least 21. Non-compliance carries a $500,000 daily fine. Additionally, Kalshi faces private litigation from FlightAware, which alleges the platform used its data and trademark without permission to settle wagers on flight cancellations. Despite these challenges, Kalshi has expanded into regulated crypto derivatives and reported monthly notional trading of approximately $40 billion in August. ## Claims - Kalshi has removed all sports-related mention markets from its platform until further notice. (disputed by 6 sources) - Kalshi continues to allow mention markets for political events, earnings calls, and live news broadcasts. (disputed by 5 sources) - Many prediction market activities are classified as unregulated gambling and are illegal in British Columbia. (corroborated by 16 sources) - Online gambling in British Columbia is restricted to the PlayNow platform operated by the B.C. Lottery Corporation. (corroborated by 16 sources) - New Jersey filed a petition for a writ of certiorari with the U.S. Supreme Court on September 2. (corroborated by 14 sources) - The Ninth Circuit ruled 3-0 that state gaming laws can apply to prediction market sports contracts. (corroborated by 13 sources) - New York Attorney General Letitia James filed a lawsuit against Kalshi in Manhattan state Supreme Court. (corroborated by 10 sources) - The lawsuit alleges Kalshi operates without a license from the New York State Gaming Commission. (corroborated by 10 sources) - Kalshi argues it is regulated by the federal Commodity Futures Trading Commission (CFTC). (corroborated by 10 sources) - Kalshi has asked that the case be transferred to a federal court, describing the state lawsuit as political theater.
