Kalshi has entered a multi-year partnership with Nasdaq to adopt the exchange operator's market surveillance platform and has separately joined The Digital Chamber, linking the U.S.-regulated prediction-markets venue to a leading digital-asset advocacy group as Washington debates rules for event contracts. Kalshi said Nasdaq's system will be rolled out in phases alongside its existing surveillance framework, with round-the-clock monitoring intended to detect market abuse, manipulation and insider trading in real time and to support delivery of trade data to the Commodity Futures Trading Commission in the format the agency requires. The moves come as lawmakers and regulators intensify scrutiny of suspicious trading on event-based contracts. Last month, the CFTC fined former Republican Representative George Santos $35,000 over alleged manipulative trading on Kalshi, and Reuters reported that a White House teleprompter operator is under investigation over potential insider trading on the platform. Kalshi said it referred suspicious trading activity in both cases to regulators and has been expanding its surveillance unit this year. Separately, The Block reported that Kalshi joined The Digital Chamber, formerly the Chamber of Digital Commerce, with both sides citing goals including stronger consumer protection, reasonable regulation and preserving U.S. leadership in prediction markets.
