Insider trading has been a real headache for prediction markets, and in the last few months, several high-profile cases have prompted a very serious question: How can prediction platforms prevent insiders from using sensitive, non-public information for speculative gain?
In a milestone development for the industry, CFTC-regulated exchange Kalshi announced a multi-year partnership with Nasdaq to deploy the legacy exchange operator’s institutional market surveillance technology.
The Kalshi – Nasdaq Partnership
Under the agreement, Kalshi is integrating Nasdaq’s surveillance architecture into its core infrastructure in phases.
Kalshi will combine its internal risk monitoring with Nasdaq's automated, 24/7 trade surveillance engines, the same systems utilized by global equities and derivatives exchanges, to detect suspicious trading patterns, market manipulation, and insider trading in real time.
Crucially, the system also streamlines Kalshi's regulatory data delivery to the Commodity Futures Trading Commission, meeting the strict reporting formats required of a Designated Contract Market (DCM).
What the Partnership Means
The integration of Nasdaq’s surveillance tech represents far more than an operational upgrade. It establishes a critical line of defense.
Regulatory Alignment with the CFTC
As the CFTC faces pressure from lawmakers over market integrity and the sports-versus-derivatives boundary, regulated exchanges must prove they can police their order books. Automated, real-time reporting to regulators reduces compliance friction and reinforces Kalshi’s position as a federally recognized DCM.
Real-Time Detection
Prediction market oversight often relied on retrospective investigations after trade settlement. Nasdaq's platform uses algorithmic pattern recognition to flag statistically anomalous win rates, coordinated trading groups, and pre-announcement volume spikes before funds are withdrawn, allowing compliance teams to freeze compromised accounts instantly.
Institutional Onboarding & Deep Liquidity
Hedge funds, institutional market makers, and corporate treasuries have hesitated to deploy large-scale capital into prediction markets due to compliance risks. By using Nasdaq's surveillance infrastructure alongside strict protocols, Kalshi offers institutional traders a familiar, compliant platform.
High-Profile Cases That Prompted the Crackdown
The move toward automated institutional surveillance comes on the heels of growing scrutiny from lawmakers and a series of high-profile enforcement cases involving political candidates, government officials, and media insiders trading on non-public information.
The integrity of political event contracts was put to a direct test when Kalshi uncovered multiple political candidates trading on their own election outcomes.
In one landmark enforcement action, Kalshi fined and issued five-year platform bans to three congressional candidates, including Virginia Senate candidate Mark Moran and congressional candidates Ezekiel Enriquez and Matt Klein, after flagging bets placed on their own campaigns. Earlier this year, a candidate for Governor of California was similarly penalized after posting a video in which he appeared to trade his own election contract.
Government enforcement reached a major milestone when the CFTC issued a $35,000 fine on former Republican Representative George Santos over alleged manipulative trading on Kalshi.
Simultaneously, federal authorities launched investigations into potential insider trading involving executive administration staff, including reports surrounding a White House teleprompter operator accused of trading political event contracts related to President Donald Trump’s speeches.
A New Chapter For The Industry?
It was clear: security measures were needed to avoid further friction between prediction markets and the law. It seems that the era of self-policing or simple post-trade audits is over.
By embedding Nasdaq’s surveillance technology directly into its matching engine, Kalshi is drawing a clear line between CFTC-regulated financial exchanges and offshore, unpoliced event markets.
