Kalshi notifies CFTC of planned anti-harassment rulebook changes
Kalshi has notified the Commodity Futures Trading Commission that it is adding anti-harassment terms to its rulebook. The changes would give the prediction market platform latitude to punish users, and fines could be among the enforcement mechanisms. The move comes as Kalshi expands its sports event contract offerings and faces heightened scrutiny around user conduct. Separately, Kalshi CEO Mansour warned that state-level crackdowns on CFTC-regulated sports contracts could drive users to offshore platforms.
Kalshi is building enforcement tools while its CEO frames state pressure as an existential competitive threat. The anti-harassment rulebook gives Kalshi a conduct lever to pull before regulators or courts force broader platform changes. That matters because Kalshi is already fighting preemption battles in Ohio and Tennessee, where it lost federal shield protection. Each state suit that succeeds becomes template law the next attorney general copies.
Mansour's offshore warning reveals the platform's fear: geofenced state-by-state availability advantages unregulated competitors. Kalshi must now invest in user-policing infrastructure, parallel legal defense across multiple jurisdictions, and possible product redesign simultaneously. The first major operator to lose another state case sets the compliance bar every competitor must clear.
