- Kalshi has entered a multiyear partnership with Nasdaq to adopt the exchange operator's market surveillance platform, deploying it in phases to bolster trade oversight on its prediction markets.
- The integration pairs Kalshi's existing surveillance framework with advanced monitoring for prediction markets and perpetual-style derivatives, enabling real-time detection of market abuse, manipulation, and insider trading, and delivering trade data to the CFTC in its required format.
- The deal comes amid mounting lawmaker pressure following high-profile alleged insider trading cases, including a $35,000 CFTC fine last month on former Rep. George Santos for alleged manipulative trading on Kalshi.
- A White House teleprompter operator is also under CFTC investigation for potential insider trading on Kalshi, per Reuters; Kalshi referred both cases to regulators and prohibits market manipulation and insider trading.
- Nasdaq's surveillance platform already serves over 50 exchanges and 20 international regulators globally, per the company's Tony Sio, who called prediction markets "among the fastest-growing segments of the financial landscape."
- Kalshi VP Max Crowley said the deal reinforces the company's "commitment to market integrity" and gives it access to surveillance data used by the world's largest exchanges.
- Kalshi has also ramped up hiring in its surveillance unit this year as prediction-market scrutiny has intensified.
Why it matters: Kalshi is voluntarily importing surveillance infrastructure that already monitors 50+ global exchanges just as a White House insider-trading probe and a $35,000 CFTC fine on former Rep. George Santos have put prediction-market integrity under intensified lawmaker and regulator scrutiny — buying credibility before Congress or the CFTC impose formal conduct rules of their own.
