On August 11, the Commodity Futures Trading Commission invoked emergency powers for the seventh time in its history. Chairman Mike Selig signed Release 9281-26, directing KalshiEX to ignore New York's $36 billion lawsuit and keep operating. The order marked the first time the CFTC used Section 8a(9) against a state attorney general, and the first time since 1980 the agency had exercised that authority at all.
New York Attorney General Letitia James and Governor Kathy Hochul filed the civil enforcement action on July 31. The complaint, running more than 100 pages, alleges Kalshi runs an illegal gambling business by offering sports prediction contracts without a license from the New York State Gaming Commission. The damages demand includes return of all customer funds wagered in the state, a $100,000 penalty per sports contract, and full disgorgement of profits. James also noted Kalshi lets users as young as 18 trade sports contracts, while New York requires mobile sports bettors to be 21.
Kalshi became a CFTC-registered designated contract market in 2020, the first exchange dedicated to event contracts. For three years it listed markets on economic data, weather, and policy outcomes. The shift came in September 2023, when the CFTC itself tried to block election contracts. Kalshi sued and won. The D.C. Circuit declined to stay the ruling in October 2024, and by early 2025 the CFTC dropped its appeal. Under Selig, appointed in early 2025, the agency reversed course, withdrew its proposed rule defining "gaming" to include election contracts, and in January 2025 Kalshi self-certified sports event contracts.
The speed of expansion caught state regulators flat. Within months Kalshi processed billions in monthly volume on NFL, NBA, and MLB markets. The platform marketed itself as a regulated alternative to offshore sportsbooks. For state gaming commissions that built licensing frameworks after the Supreme Court struck down the federal sports betting ban in Murphy v. NCAA (2018), the message was clear: a federally licensed exchange offered the same product without state taxes, licenses, or consumer protections.
New York's legal theory rests on three arguments. Prediction contracts on sporting events are wagers under state law regardless of federal classification. The Federal Interstate Wire Act prohibits interstate transmission of information that assists sports betting. The CFTC's framework cannot preempt state gambling enforcement because the Commodity Exchange Act was never intended to authorize a nationwide sports betting operation. The lawsuit followed a cease-and-desist order from the New York State Gaming Commission in October 2025 and criminal charges filed by Arizona's attorney general in March 2026. More than 20 lawsuits and cease-and-desist actions are pending nationwide.
The CFTC's emergency order found that a "sudden, unpredictable shutdown" of a registered designated contract market constituted an emergency. The Commission argued Kalshi's closure would strand open positions, disrupt price discovery, and undermine the federal regulatory framework. This was the second emergency order for Kalshi in 30 days; the first, in mid-July, attracted less attention.
The core legal question: does the Commodity Exchange Act preempt state gambling law for contracts traded on CFTC-registered exchanges? The CFTC says yes, citing the Act's grant of "exclusive jurisdiction" over futures contracts and the 23 Core Principles covering market surveillance, financial integrity, and customer protection. A coalition of 44 state attorneys general, led by Ohio AG Andy Wilson and excluding only Texas, Florida, Georgia, Missouri, and New Hampshire, says no. They point to the Act's savings clause preserving state jurisdiction over fraud and manipulation, combined with the Tenth Amendment. They argue prediction contracts on sporting events look, function, and are marketed identically to sports bets.
A federal appellate court gave a partial answer in April 2026, ruling the Commodity Exchange Act "likely" preempts state gambling laws for sports event contracts on CFTC-licensed designated contract markets. The court affirmed a preliminary injunction barring New Jersey from enforcing its gambling laws against Kalshi. The ruling was preliminary and addressed a single state. The New York case, with its massive damages claim and constitutional arguments, will force a more definitive resolution.
For crypto markets, the stakes extend beyond prediction contracts. If the CFTC's preemption theory prevails, any platform operating through a federal derivatives license could argue state money transmitter laws, securities regulations, and gambling statutes do not apply. The precedent would create a single federal passport for crypto derivatives, similar to Europe's MiFID and MiCA framework.
Polymarket's U.S. operations are directly affected. The platform settled with the CFTC in 2022 for operating an unregistered trading facility and restricted U.S. users. It began a phased U.S. rollout under an intermediated model in late 2025, and by March 2026 had self-certified new market rules for its U.S. venue. In February 2026, Polymarket set a single-day trading volume record of $425 million. A reported CFTC investigation into its marketing practices adds uncertainty. If state gambling laws apply despite CFTC oversight, Polymarket would need gaming licenses in every state. If preemption holds, federal registration becomes a nationwide operating license.
The broader prediction market industry recorded $50.59 billion in combined monthly trading volume in July 2026 across Kalshi, Polymarket, and Polymarket US. Sports betting generated roughly $14 billion in state tax revenue in fiscal 2025. If prediction markets capture a meaningful share of sports wagering under a federal license that bypasses state taxation, the fiscal consequences for state budgets would be severe.
The CFTC's June 2026 proposed rule is broadly receptive to sports event contracts but would ban markets on player injuries, officiating decisions, and certain in-game actions. It also proposes banning contracts on war and assassination. The 44-state coalition urged the CFTC to withdraw and rewrite the rule entirely. The comment period closed in late July, days before the New York lawsuit was filed.
Native American tribes that operate sports betting under compacts also entered the fight. Several tribal nations filed amicus briefs supporting the states, arguing federal preemption would undermine the sovereignty-based framework governing tribal gaming.
The prediction market industry's combined volume of $50.59 billion in July 2026 explains the intensity. A product that walks like a wager and is sold as a wager, relabeled as a "derivative," now sits at the center of a constitutional conflict that may define federal-state regulatory boundaries for crypto assets.
The next 90 days will shape the trajectory. New York will seek to have the emergency order declared invalid, arguing Section 8a(9) was designed for commodity market emergencies, not for shielding companies from state law enforcement. The CFTC will seek a federal court injunction preventing New York from enforcing its complaint. Whichever court rules first will set terms for an appellate battle that could reach the Supreme Court within 18 months.
The CFTC's final prediction market rule, expected by late 2026 or early 2027, will define which event contracts are permissible and whether the Commission explicitly asserts preemption in the regulatory text. A strong preemption statement would give courts a clearer basis for deferring to the federal framework.
Congressional action remains a wildcard. The Prediction Markets Security and Integrity Act of 2026, S. 4060, addresses insider trading on prediction markets but does not resolve preemption. Multiple bills addressing the gap are reportedly in draft form in both chambers. A legislative fix that allows states to collect taxes on prediction market activity without granting them the power to ban federally licensed contracts would represent the most pragmatic resolution.
If New York succeeds in extracting even a partial settlement from Kalshi, other states will file similar suits within weeks. If the CFTC's emergency order holds, the agency will have created a precedent that makes state enforcement actions against any CFTC registrant far more difficult, with implications extending to every crypto exchange, stablecoin issuer, and DeFi protocol that might someday seek a federal license.
Prediction market volumes grew from a niche curiosity to a $50 billion monthly industry in barely two years. If regulatory uncertainty causes platforms to pull back from sports contracts, that volume will migrate offshore, to unregulated venues beyond the reach of either federal or state oversight. Both sides of this fight claim to be protecting consumers. Prolonged legal warfare may drive consumers toward the least protected venues of all.
