Kalshi Strikes Strategic Partnership With Nasdaq
Kalshi announced a multi-year partnership with Nasdaq on Monday, deploying Nasdaq’s market surveillance technology across its prediction market and perpetual futures products.
The platform will implement Nasdaq’s surveillance system in phases, combining existing monitoring with capabilities designed for real-time detection of market abuse, manipulation, and insider trading. The partnership also supports Kalshi in delivering trading data to the CFTC in the required regulatory format.
Among the details of the new partnership, one detail jumps out. The CFTC itself adopted Nasdaq Market Surveillance in August 2025. Kalshi’s regulator and Kalshi now use the same surveillance platform. That is either a coincidence or a deliberate signal. Given the regulatory environment Kalshi is operating in, it is probably the latter.
An Operationally Sound, Strategically Savvy Move
Kalshi is fighting a $36 billion lawsuit from the New York attorney general. Utah’s federal court granted summary judgment against it last week. The CFTC’s emergency attempt to block New York’s case was denied. The Sixth Circuit heard oral arguments on the Ohio and Tennessee appeals two weeks ago, as lawmakers continue circulating proposals to restrict or ban the platform’s sports contracts.
Into that environment, Kalshi has partnered with the world’s most recognizable stock exchange brand to put institutional-grade surveillance on its markets. The announcement is operationally real and strategically savvy. Nasdaq’s platform serves more than 50 exchanges and 20 international regulators. It is also unmistakably a credibility play. You do not hire Nasdaq to quietly watch your markets. You hire Nasdaq and then put out a press release, so that lawmakers and regulators have one more talking point working against them.
The Van Dyke military intelligence case, the Spagnuolo Google data case, and the Perez teleprompter case have all handed critics a consistent line of attack: prediction markets are too porous to monitor effectively. The Nasdaq partnership is a direct answer to that attack. Whether it is a sufficient answer depends on whether the surveillance technology is actually deployed at a standard that catches what it is supposed to catch, which a press release cannot confirm.
Polymarket and Kalshi Are Focused on Legitimacy
At this point, Polymarket and Kalshi are not just competing for market share. They are competing for institutional legitimacy through their exchange partnerships.
Intercontinental Exchange, the parent company of the New York Stock Exchange, made an initial $1 billion investment in Polymarket in October 2025, then completed an additional $600 million investment in March 2026. Under the terms of that deal, ICE became the global distributor of Polymarket’s event-driven data to institutional investors and agreed to partner on tokenization initiatives. ICE is the parent company of the New York Stock Exchange, founded in 1792. Its $1.6 billion total commitment to Polymarket was not as much a venture capital bet as it was a data infrastructure decision.
Kalshi’s Nasdaq partnership is structured differently. Nasdaq is a customer relationship: Kalshi is buying surveillance technology, not selling equity. Tradeweb made a minority investment in Kalshi in February, with a focus on expanding institutional access to prediction market data. The institutional infrastructure around Kalshi is being built through technology partnerships and investor relationships. The institutional infrastructure around Polymarket has been built through a $1.6 billion equity commitment from the exchange that invented the modern stock market.
Both approaches signal the same strategy. The major financial infrastructure companies in the world have decided that prediction markets are a real asset class that requires real exchange-grade oversight. The debate about whether prediction markets belong in the financial system is technically now over at the institutional level. The debate about whether they belong in every American state is still running in seven federal circuits.
Nasdaq and Kalshi Have Lots to Gain From This Parntership
Nasdaq’s surveillance business serves exchanges, and Kalshi is becoming an exchange. As Kalshi builds out beyond prediction markets, Nasdaq will be an important partner in that next chapter, according to Kalshi’s own announcement. That framing points toward the Bitcoin perpetual contracts already live on the platform, the sports perps under discussion, and whatever other derivatives products Kalshi is planning to list as its product suite expands.
Surveillance revenue is recurring and grows with trading volume. Kalshi’s trading volume grew from $9 billion per month to over $30 billion per month during the World Cup. The NFL season starts in three weeks. If prediction market volume continues on its current trajectory, Nasdaq has just signed a long-term contract with one of the fastest-growing financial platforms in the country.
The political and legal headwinds are real, and the commercial momentum is equally real. Nasdaq made a business decision based on the second, while Kalshi gets to use the partnership to push back against the first.
