A letter, a lawsuit and a court order are three different steps
- Letters and orders come from a state agency or an attorney general, not from a court. Missouri's letters asked each company to comply within 30 days (KCTV5).
- Lawsuits and petitions ask a court to decide. New York has sued Kalshi, Polymarket and Coinbase; Michigan, Utah and Washington have sued Kalshi.
- Court orders and rulings come from a judge, and some are being appealed. Kalshi appealed the Washington injunction (DeFi Rate).
The platforms and the states disagree about who has authority. Polymarket's reply to New York's lawsuit argued that the federal CFTC has exclusive authority over prediction markets (Al Jazeera), and Kalshi said after the Washington ruling that states do not have jurisdiction (DeFi Rate). The Ninth Circuit ruled on 28 August 2026 that Kalshi's sports contracts are sports bets rather than federally regulated swaps (Gambling.com).
