Kalshi Faces Lawsuit Alleging Illegal Sports Betting Operations
WASHINGTON D.C. – Kalshi, a federally regulated derivatives exchange, is responding to a newly filed lawsuit alleging its event contracts constitute illegal sports betting.

Lara defended the platform, stating it is indeed “structured as a federally regulated derivatives exchange, overseen by the Commodity Futures Trading Commission.” She further asserted on X (formerly Twitter) that the lawsuit is a “pure smear campaign” fueled by a competitor paying to amplify “baseless” allegations.

The allegations are false and reveal a fundamental (and maybe intentional) misunderstanding of how these…”
The legal challenge echoes previous issues faced by polymarket, another prediction market platform. Polymarket was able to resume U.S. operations after acquiring a derivatives exchange and clearinghouse to ensure full regulatory compliance.
