CFTC Weighs Enforcement Probe Into Kalshi’s Ether Perps Over Repeating $5,500 Trades

The significance here is jurisdictional as much as factual: a US-regulated venue built around event contracts is now facing scrutiny over how it handles perpetual futures flow, a product category the CFTC has policed aggressively. Kalshi's defense — that a market maker was picked off by faster traders — frames the issue as market structure rather than exchange misconduct, which shifts the question toward whether the agency treats repeated, identifiable trade patterns as a surveillance failure by the venue. The open question is whether the CFTC formalizes a case, and what that would signal about perps on regulated US platforms.
