# US prediction market regulatory crackdown > Live situation record from CLSTR: https://clstr.news/situations/us-prediction-market-regulatory-crackdown > Updated: 2026-08-03T00:02:29.000Z. Sources: 24. Developments: 2. In late July 2026 the Nevada Gaming Control Board ordered the shutdown of Kalshi’s sports prediction market, citing regulatory concerns. The decision coincided with a $400,000 betting surge on a Monterrey Liga MX match, $300,000 on the Toluca‑Cruz Campeón de Campeones game, and heavy wagering on Brazilian Serie A clubs such as Flamengo, São Paulo, Palmeiras and Atlético Mineiro. At the same time federal prosecutors charged Staten Island mob capo Joseph Lanni in an 11‑state poker‑rigging indictment that alleges the use of rigged shufflers, X‑ray tables and hidden card analyzers to cheat high‑stakes players. By early August, activity on prediction‑market platforms shifted toward geopolitical contracts, with millions of dollars traded on scenarios such as a U.S. invasion of Iran and an Israel‑Iran ceasefire. Concurrently, New York Attorney General Letitia James and Governor Kathy Hochul filed a lawsuit on July 31 in Manhattan Supreme Court accusing Kalshi of operating an illegal, unlicensed gambling business. The complaint alleges that users as young as 18 can wager on sports, elections and other events without a New York gaming license or required taxes, and seeks forfeiture of illegal gains, restitution for consumers and civil penalties up to three times the company’s profits—estimated at up to $36 billion. Kalshi maintains its contracts are CFTC‑regulated derivatives; a CFTC emergency motion to block the suit was denied by a federal judge. Kalshi’s CEO Tarek Mansour called the case “political theater” and blamed the gambling lobby, while other states have launched similar actions, underscoring a growing clash between federal commodity‑derivatives regulation and state gambling laws. ## Claims - The lawsuit alleges Kalshi operates an illegal, unlicensed gambling business in New York.
