Feds Block New York's $36B Gambling Case Against Kalshi

Feds Block New York's $36B Gambling Case Against Kalshi

New York spent months building a case against a company it says is running an unlicensed gambling operation inside state lines. Then, within days of filing that case, a federal agency stepped in and effectively ordered the state to stand down while the company keeps operating exactly as before. That alone would be a notable federalism story. What makes it worth a closer look is who stands to benefit financially from the federal government winning this fight — and it isn't just the company being sued.

What New York Actually Filed

On July 31, 2026, New York Attorney General Letitia James and Governor Kathy Hochul sued KalshiEX LLC, arguing the prediction-market platform is functionally running unlicensed sports betting inside the state without paying the taxes licensed casinos and mobile sportsbooks are required to pay. The state's numbers are aggressive: it's seeking roughly $36 billion in damages, calculated under a New York law that lets the state fine illegal gambling operators three times their in-state gains, plus $100,000 for every individual bet placed by a New York resident. The lawsuit followed a cease-and-desist letter New York's Gaming Commission had already sent Kalshi back in October 2025, which the company appears to have simply continued operating through.

The Federal Government's Response Was Immediate and Blunt

The Commodity Futures Trading Commission didn't wait for the case to play out in court. It filed an emergency motion for a temporary restraining order, arguing New York has no authority to touch Kalshi at all, because the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts traded on federally designated exchanges — a status Kalshi has held since 2021. CFTC Chairman Michael Selig framed New York's lawsuit as an attempt to "abruptly shut down prediction markets across the nation," and in a separate statement warned that letting states enforce their own gambling laws against Kalshi could "bring entire federally regulated markets to the brink of destruction." As of this week, Kalshi remains fully operational in New York while the two sides fight it out in federal court.

New York Isn't the First State. It's Not Even the Most Aggressive Fight.

This pattern has repeated across roughly a dozen states since Kalshi expanded into sports contracts in early 2025. The CFTC has now filed lawsuits or intervened against Arizona, Connecticut, Illinois, Wisconsin, Minnesota, and New York, while thirty-nine state attorneys general, spanning both parties, have sided with Nevada in its own fight to enforce state gambling law against Kalshi. Courts have split on the underlying legal question: the Third Circuit Court of Appeals ruled, in a divided decision, that the CFTC holds exclusive jurisdiction over sports-related event contracts, while a federal court in Maryland reached the opposite conclusion and denied Kalshi's request for an injunction against state enforcement. The most aggressive escalation so far happened in Michigan, where the CFTC invoked emergency authority to order Kalshi to defy a state judge's ruling requiring it to unwind and refund sports-related trades placed by Michigan residents. Kalshi told the CFTC it couldn't comply anyway, because it had already liquidated the trades the judge ordered undone — a detail that shows just how far ahead of any court resolution this fight has already moved.

The Part of This Story That Isn't About Federalism at All

Here's where this stops being a straightforward jurisdictional dispute. Donald Trump Jr. has been a paid strategic advisor to Kalshi since January 2025, and has since been granted an equity stake in the company as it moves toward a potential IPO — a stake that could turn into a significant financial windfall if Kalshi's federally protected status survives this wave of state lawsuits. He also sits on the advisory board of Polymarket, a rival prediction market, after his venture firm 1789 Capital made a separate investment in that platform. President Trump has publicly weighed in on the CFTC's side of this fight, calling opponents of the industry "scum" on social media and praising Selig by name as "doing a great job." None of that, on its own, proves the administration's legal position is wrong. But it does mean the federal government pushing hardest to override state gambling enforcement is doing so in a way that directly benefits the president's own son.

Congress Already Asked About This, and Got a Non-Answer

This isn't a connection reporters uncovered on their own — it came up directly in Selig's first congressional testimony as chairman. Democratic Rep. Jim McGovern asked him point-blank to acknowledge that the Trump family has a financial stake in how these markets are regulated, calling the arrangement "the definition of corruption" and suggesting Selig's deregulatory push was actively helping enable it. Selig confirmed he was aware of Trump Jr.'s roles at both companies, but declined to directly answer whether that constituted a conflict of interest, instead pointing to the agency's enforcement record on insider trading. It's also worth noting Selig wasn't the administration's first choice for the job: his predecessor nominee, Brian Quintenz, sat on Kalshi's board and held Kalshi stock before senators pressed him on the same conflict-of-interest questions, and his nomination was ultimately withdrawn, reportedly at the request of separate crypto industry figures who felt he wasn't sufficiently aligned with their interests, not over the Kalshi ties themselves.

There's Also an Integrity Problem Inside the Markets Themselves

Separately from the jurisdictional fight, experts have flagged a pattern of unusually well-timed, lucrative trades on rival platform Polymarket immediately before major geopolitical events, including US and Israeli strikes on Iran and the capture of Venezuela's leader in January. Kalshi doesn't currently offer war-outcome contracts the same way, but it did refund every losing trade on a disputed market tied to the tenure of Iran's supreme leader after the market's outcome became contested — an unusual step for a platform that otherwise settles contracts based on strict, predetermined criteria. There is no public evidence tying Trump, his family, or any administration official to suspicious trades on either platform, and Selig has said the CFTC maintains a "zero tolerance policy" for insider trading. But the fact that these markets are simultaneously fighting to avoid state gambling oversight while facing genuine, unresolved questions about trading integrity is not a detail that fits neatly into the industry's preferred framing of this fight as pure regulatory turf war.

Conclusion

Strip away the politics and there's a real, unresolved legal question at the center of this: does a federal derivatives designation actually preempt state gambling law, or doesn't it? Courts genuinely disagree, which is why this keeps ending up in front of judges rather than getting settled cleanly one way or another. But the legal ambiguity is exactly what makes the political dimension impossible to ignore. When the party best positioned to resolve that ambiguity in Kalshi's favor is led by an administration whose own president's son holds a paid, and now equity-bearing, stake in the outcome, "just following the statute" becomes a much harder claim to take entirely at face value. New York's $36 billion lawsuit may or may not survive the CFTC's legal challenge. What's already clear is that whoever wins this particular fight, the Trump family wins something regardless of how a judge eventually rules.
