Prediction Markets Dealt Blow as New York Court Rejects Kalshi

⏱ 3 min read

A Manhattan federal judge handed prediction markets their most consequential courtroom defeat yet on July 7, 2026, denying Kalshi's bid to block New York from enforcing state gambling laws against its sports-event contracts. The ruling by U.S. District Judge Analisa Torres — in the case KalshiEX LLC v. Williams — rejected Kalshi's core legal theory that its federal registration with the Commodity Futures Trading Commission (CFTC) pre-empts state authority over what it lists.

The timing is striking. Kalshi posted $33 billion in trading volume in June 2026 alone — a 70%+ surge from May's $17.9 billion — driven largely by 2026 FIFA World Cup sports contracts. The entire prediction markets sector cleared $50 billion in June, according to Macquarie Equity Research, putting the industry on an annualised pace above $500 billion. Yet the New York loss, combined with simultaneous Senate and sportsbook pressure, signals that the regulatory walls are closing in from multiple directions at once.

The New York Court Ruling

Judge Torres applied the strict standard governing injunctions against government enforcement actions. She concluded Kalshi had not shown a clear likelihood of success on the merits of its federal pre-emption argument. The court found a strong presumption against federal pre-emption in areas — like gambling regulation — that have traditionally been left to states, and determined that Congress never intended the Commodity Exchange Act to strip states of that authority.

Torres further ruled that Kalshi had not demonstrated irreparable harm: compliance costs and potential business disruption are monetary losses that can be repaid, while the state's interest in shielding residents from gambling addiction and protecting sports integrity "heavily" outweighs the platform's interests. The New York State Gaming Commission was dismissed from the case on Eleventh Amendment immunity grounds, though claims against individual commissioners survive. Kalshi immediately filed an interlocutory appeal to the Second Circuit.

Governor Kathy Hochul and Attorney General Letitia James issued a joint statement the following morning, saying New York's gambling laws are built to protect consumers and that Kalshi had attempted to circumvent them. Kalshi said it respectfully disagreed and was pursuing all legal options.

Senate Democrats Move to Defund CFTC Enforcement

On July 6, 2026, U.S. Sen. Jacky Rosen (D-NV) joined colleagues in a letter to the Senate Appropriations Subcommittee on Financial Services and General Government seeking to prohibit the CFTC from spending appropriated funds on lawsuits against states and tribal nations that are regulating prediction markets. The letter was led by Sens. Richard Blumenthal (D-CT) and Jeff Merkley (D-OR), and also signed by Sen. Catherine Cortez Masto (D-NV).

The senators named eight states — Connecticut, Illinois, Arizona, Wisconsin, New York, Minnesota, Rhode Island, and New Mexico — that the CFTC has sued in recent months while seeking to block state gambling enforcement. Tribes in Wisconsin, California, and New Mexico have separately sued prediction market operators under the Indian Gaming Regulatory Act.

The push reflects Nevada's specific economic concern. Sen. Cortez Masto stated that event contracts tied to sports and casino games "are nothing more than gambling and fall entirely within the jurisdiction of tribes and states." The CFTC's aggressive posture under President Trump — whose son Donald Trump Jr. serves as a paid adviser to both Kalshi and rival Polymarket, receiving roughly $300,000 in Kalshi equity — has drawn pointed ethics scrutiny alongside the legal battles.

Nevada Sportsbooks Report Real Volume Losses

At a Nevada Gaming Control Board meeting on July 9, 2026, licensed sportsbook executives testified that prediction markets are already eroding their business. Nevada sportsbook handle is down $249 million year-over-year in 2026. Monthly figures from the Control Board tell the story quarter by quarter:

• March 2026: $763M wagered, down 11.3% vs. March 2025
• April 2026: $525.1M wagered, down 15.1% vs. April 2025
• May 2026: $545.7M wagered, down 5.4% vs. May 2025

Caesars Digital President Eric Hession said the company is not yet seeing a significant revenue-line impact but acknowledged volume pressure is real. Joe Asher, CEO of Boomer's Sportsbook and a Hall of Fame bookmaker, said he had personally witnessed customers placing Kalshi bets at a Nevada restaurant despite the court-ordered prohibition, and found Kalshi ads appearing in Apple App Store searches for licensed Nevada sportsbooks — even after Kalshi was ordered to cease Nevada operations.

The State-by-State Battlefield

The New York ruling deepens a circuit split that is increasingly pointed toward the U.S. Supreme Court. Kalshi has won protective orders in New Jersey (affirmed by the Third Circuit) and Tennessee, but lost comparable bids in Maryland, Arizona, and now New York. Michigan recently ordered a halt to Kalshi's sports contracts; Minnesota passed a law making it a felony to operate or participate in prediction markets starting August 1, 2026.

State	Action Against Prediction Markets	Current Status
New York	Cease-and-desist (Oct 2025); NYSGC enforcement lawsuit	Injunction denied July 7, 2026; Kalshi appealing to 2nd Circuit
Nevada	Cease-and-desist (Mar 2025); state court lawsuit; contempt motion	Preliminary injunction in place; 9th Circuit sided with Nevada on procedure
Minnesota	Felony ban signed into law	Law takes effect August 1, 2026; CFTC/DOJ seeking federal injunction to block
Arizona	20 criminal counts filed (AG Kris Mayes)	CFTC countersued; federal judge blocked state criminal enforcement
New Jersey	State enforcement attempt	3rd Circuit affirmed injunction protecting Kalshi — currently operating
Michigan	Court order to halt sports contracts	Temporary block in place

What It Means for Operators and Bettors

For licensed sportsbooks and online casinos in regulated markets, the practical message from Judge Torres's ruling is that federal CFTC registration is not the blanket shield Kalshi has treated it as. Operators who had been counting on a single national rulebook now face the prospect that prediction market competitors may ultimately need to comply state by state — the same patchwork that licensed books already navigate, but without the same tax and consumer-protection obligations in the interim.

For bettors, the fragmented landscape creates real access uncertainty. Platforms can restrict users with little notice as court orders land. Roughly 87% of Kalshi's lifetime trading volume through mid-2026 has been sports-related, per Congressional Research Service data, making it functionally the largest sports-betting operation in the United States — yet one operating without state consumer protections in most jurisdictions, including age verification scrutiny and problem-gambling safeguards that licensed books are required to provide.

The next pivot points: Kalshi's appeal to the Second Circuit, the Minnesota enforcement showdown in late July, and whether the Senate Appropriations Subcommittee acts on the Rosen-Cortez Masto letter to cut off CFTC litigation funding against states.

New York's gambling laws are designed to protect consumers. Kalshi tried to ignore them. We will continue to hold all gambling platforms accountable to the law — and that includes prediction markets.
