Kalshi Clash with Montana Intensifies over Market Rules

Summary

Kalshi has filed a federal lawsuit seeking to block Montana regulators from treating its event contracts as gambling. The company says its markets are federally regulated derivatives overseen by the CFTC; Montana’s Gambling Control Division says the contracts amount to wagers and issued a cease-and-desist despite an earlier pause in enforcement. Similar disputes are underway in Arizona, New Jersey and Massachusetts, and courts remain split. The Montana case could significantly influence whether prediction markets are regulated as finance or gambling.

Key Points

The dispute centres on whether event contracts are CFTC-regulated derivatives or state-level wagers subject to gambling laws.
Montana issued a new cease-and-desist despite agreeing in 2025 to pause enforcement while related litigation continued.
Kalshi faces parallel legal battles in Arizona, New Jersey and Massachusetts, producing mixed judicial rulings so far.
Kalshi warns state-by-state regulation would fragment markets and harm regulated exchanges; Montana has not yet filed a court response.
