Ohio sent cease-and-desist notices to three firms including Kalshi, Robinhood, and Crypto.com, ordering them to stop offering or facilitating sports event contracts. The notices target prediction market platforms and related exchanges. The action marks an escalation in state-level enforcement against event contracts tied to sporting outcomes.

State-level C&Ds create a patchwork compliance risk for platforms already navigating federal CFTC oversight. If other states follow Ohio's lead, multi-state operators could face a wave of geoblocks or product withdrawals even on CFTC-regulated contracts.
