Kalshi enters NFL Week 1 with its sports event-contract business under pressure on three fronts: New York’s July 31 lawsuit seeking more than $36 billion in relief, an August 11 CFTC emergency order backing continued federal oversight, and a fast-moving dispute over NFL player-availability contracts that Kalshi removed days after listing them.

What is New York claiming against Kalshi?

New York Governor Kathy Hochul and Attorney General Letitia James announced on July 31, 2026, that the state had sued KalshiEX LLC, accusing the CFTC-regulated exchange of operating an illegal, unlicensed gambling business in New York. The Office of the New York Attorney General said the lawsuit seeks an order stopping Kalshi from operating as an unlicensed gambling business, plus fines, forfeiture of gains and restitution to users.

The New York petition frames Kalshi’s sports, culture and election contracts as gambling under state law because customers stake money on uncertain outcomes outside their control. The Attorney General’s July 31 release said Kalshi has not obtained a license from the New York State Gaming Commission and allows access to users ages 18 to 20, while New York requires mobile sports bettors to be at least 21.

James called prediction markets like Kalshi “gambling platforms, plain and simple” in the July 31 announcement. Hochul said New York’s gambling laws are designed to protect consumers, prevent problem gambling, fund public services and require companies to follow the same rules as licensed gambling operators.

The damages demand is large because of the state’s penalty theory. The Attorney General’s release said New York seeks restitution, forfeiture of illegal gains and fines equal to three times Kalshi’s gains from alleged illegal conduct. CFTC Release No. 9281-26, issued August 11, said New York’s July 31 lawsuit seeks a temporary restraining order prohibiting KalshiEX from offering all event contracts nationwide and more than $36 billion in damages.

What have courts done in the New York fight?

The federal litigation has not produced a final ruling on whether New York gambling law can be enforced against Kalshi’s sports event contracts. In KalshiEX LLC v. Williams, U.S. District Judge Analisa Torres denied Kalshi’s request for a temporary restraining order and preliminary injunction on July 7, 2026. The New York Attorney General’s July 8 statement described the ruling as a court victory for the state against Kalshi.

Torres later denied Kalshi’s request for an injunction pending appeal on July 27. At the Second Circuit, a judge denied temporary administrative relief and referred the broader request for an injunction to a panel, leaving the appellate fight alive rather than resolving the preemption question.

Kalshi removed New York’s July 31 enforcement action to federal court. That procedural step moves part of the dispute before a federal judge, but it does not answer the core question: whether the Commodity Exchange Act displaces state gambling enforcement when a CFTC-designated contract market lists sports event contracts.

What did the CFTC do after New York sued?

The CFTC responded on August 11 by invoking emergency authority and ordering Kalshi to continue operating under the Commodity Exchange Act and CFTC core principles. In Release No. 9281-26, the agency said Kalshi had notified the commission of a market emergency after New York filed its July 31 complaint.

CFTC Chairman Michael S. Selig criticized New York’s position in the August 11 release, saying Congress did not intend derivatives exchanges to be regulated through a “patchwork of state gaming laws.” Selig also said New York had “no business regulating these interstate financial markets.”

The CFTC has also taken its federal-jurisdiction theory into court. Release No. 9281-26 said the agency had filed lawsuits against Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island and Wisconsin, and had filed amicus briefs in the Sixth Circuit, Ninth Circuit and Massachusetts Supreme Judicial Court.

Earlier CFTC releases state the same theory more directly. In Release No. 9251-26, issued June 12 in the New Mexico case, the commission said it sought a declaratory judgment that federal law gives it exclusive authority to regulate event contracts and a permanent injunction blocking New Mexico from enforcing preempted state laws against CFTC registrants.

That makes the Kalshi dispute more than a single-state enforcement case. If courts accept the CFTC’s position, federally registered prediction exchanges would have stronger protection against state-by-state gambling enforcement. If states prevail, sports event contracts could face licensing, geofencing or shutdown orders in individual jurisdictions.

What happened to NFL player-availability contracts?

The player-availability fight is narrower than the New York case, but more sensitive for sports leagues because it touches injuries, nonpublic availability information and single-player outcomes. CFTC product filings showed Polymarket US, operating through QCX LLC and QC Clearing LLC, withdrew two NFL American Football Player Participation Contracts on August 26, 2026.

Legal Sports Report reported on August 28 that the withdrawn Polymarket filings included a broader contract template, “Will {participant} participate in {event}?,” and a Patrick Mahomes-specific contract asking whether he would participate in the Kansas City Chiefs’ Week 1 regular-season game. The same report said Polymarket had filed the contracts on August 25 and withdrew them a day later.

Kalshi had moved first in the same category. Legal Sports Report reported on August 25 that Kalshi launched markets on whether athletes would play, including a template tied to whether a named participant would compete in a named event. By September 3, SCCG Management reported that Kalshi’s NFL player-availability category had disappeared from the platform after being listed the prior day.

The regulatory concern is not limited to settlement wording. CFTC Division of Market Oversight Staff Letter No. 26-08, issued March 12, told designated contract markets to consider whether event contracts have a heightened risk of manipulation or price distortion, particularly in sports-related markets. In March 31 remarks at NYU Law School, CFTC Enforcement Director David I. Miller separately identified injury contracts as presenting manipulation and insider-trading risk.

The NFL has also pushed against injury-adjacent products. Legal Sports Report reported that the league’s sports-betting partner announcement identified injuries, officiating and other potentially knowable or easily manipulated events as wagers the league finds objectionable. That position matters because the NFL has commercial relationships with sportsbook operators, including DraftKings, FanDuel and Fanatics, while prediction exchanges are trying to define sports event contracts as federally regulated derivatives rather than state-regulated betting products.

How large is the sports-market opportunity?

The regulatory fight matters because sports have become a major source of prediction-market activity. In the week ending around October 1, 2025, Kalshi recorded about $950 million in seven-day trading volume, up from $674 million the prior week, according to data tracked by Next Event Horizon. Sports accounted for 92% of that volume, and football accounted for 70%.

Next Event Horizon’s figures also showed that the 10 highest-volume markets during that week were NFL and college football moneyline-style markets. That snapshot does not establish Kalshi’s revenue mix, but it explains why state gambling regulators, sports leagues and the CFTC are fighting over the category: football contracts can concentrate large trading volume quickly.

Polymarket is active in the same broad sports-event category through its U.S. regulated structure, although its withdrawal of the NFL player-participation filings created an early boundary around availability markets before the regular season. Kalshi’s removal of its own NFL player-availability category narrowed that contrast, at least for Week 1.

What comes next?

The next phase is procedural but consequential. Kalshi’s New York dispute continues in federal court and at the Second Circuit, while the CFTC’s lawsuits against nine states test whether federal registration preempts state gambling enforcement for event contracts. The player-availability dispute gives the CFTC a second question for the NFL season: whether sports contracts tied to individual participation are too close to injury information and single-player manipulation risk.

The next dated federal milestone is September 14, 2026, when a preliminary-injunction hearing is scheduled in United States v. New York, according to Event Markets’ docket tracker. That hearing will not settle the entire prediction-market legal fight, but it is the next test of the CFTC’s attempt to shield federally regulated event-contract markets from New York’s gambling-law enforcement.
