The Backstory

New York becomes a central test case

Kalshi’s appeal in New York marks another escalation in a legal fight that is increasingly defining the boundary between federally regulated derivatives and state-regulated gambling. The company has built its case around a straightforward premise: event contracts listed on a Commodity Futures Trading Commission-regulated exchange are financial instruments, not wagers, and states cannot use gambling laws to stop them. New York’s federal court rejected that argument at the preliminary injunction stage, creating one of the most consequential setbacks yet for the prediction market operator.

The ruling matters because New York is both a major financial center and the largest U.S. sports betting market. If state gaming regulators can enforce gambling laws against sports event contracts there, other states may be emboldened to press similar claims. If Kalshi prevails on appeal, the decision could strengthen the argument that federal commodities law preempts state licensing regimes for a broad category of event-based markets.

The New York fight began when Kalshi challenged the state’s authority over its sports-related products, arguing that the CFTC has exclusive jurisdiction over prediction markets. In its earlier suit, Kalshi said state intervention amounted to a crackdown on lawful event-based futures contracts rather than legitimate gambling oversight, according to the company’s complaint against New York regulators. The case followed a period in which state officials, lawmakers and gaming regulators began moving faster to define the sector before it could become entrenched.

Lobbying rose as lawmakers weighed guardrails

The court battle has unfolded alongside a political fight in Albany. Kalshi increased its lobbying presence in New York as legislators advanced bills that would impose licensing requirements, age restrictions and other rules on prediction market operators. The company registered to lobby in the state on Feb. 21 under a $10,000-a-month contract with Brown Weinraub, according to reporting on Kalshi’s New York lobbying push that cited Bloomberg Law.

Those lobbying efforts reflected the stakes. Proposed state rules would put prediction platforms closer to the sports betting regulatory model, with local licenses and consumer protections. That framework would challenge Kalshi’s national model, which depends on federal oversight and uniform market access. A patchwork of state gambling rules could force platforms to block users in some jurisdictions, seek gaming licenses or restructure contracts to avoid sports outcomes.

New York lawmakers framed the effort as a response to uncertainty at the federal level. The absence of a single accepted view from courts and regulators has created openings for states to act. In New York, the policy debate has been sharpened by the size of the market: sports betting generated $2.5 billion in revenue in 2025, according to figures cited by the American Gaming Association. That makes any product resembling sports wagering a matter of fiscal and regulatory significance for the state.

Sports contracts changed the risk profile

Prediction markets long operated in a niche between finance, forecasting and political speculation. Kalshi’s success in election-related litigation helped bring the sector broader attention, but sports contracts have triggered more aggressive state responses. Regulators have been more willing to treat contracts tied to game outcomes as sports bets, even when they are listed through entities overseen by the CFTC.

That distinction was clear in Ohio, where a federal judge allowed the state to enforce gambling laws against companies offering sports event contracts. Chief U.S. District Judge Sarah D. Morrison denied Kalshi’s request for a preliminary injunction on March 9, rejecting the company’s argument that its sports markets should be insulated from state action. In the Ohio ruling against Kalshi, the court questioned whether game-score contracts fit within the traditional understanding of swaps tied to financial or commodity-related measures.

That reasoning cuts to the center of the dispute. Kalshi and similar platforms argue that contract structure, exchange listing and CFTC oversight determine the legal category. State regulators argue that economic reality and consumer use matter: if customers are staking money on sports outcomes, the product functions like sports betting. Courts have not settled on a uniform answer, creating a fragmented map in which similar products may be permitted in one state and restricted in another.

New York’s ruling adds weight to the state-regulator side of that map. It also complicates Kalshi’s effort to use litigation to secure operating certainty. Each adverse ruling makes it harder for the company to argue that state enforcement is plainly unlawful, even if appeals courts have not yet issued definitive guidance.

The CFTC’s posture has shifted the terrain

The federal regulator’s role has made the dispute more complex. The CFTC has not been a static opponent of prediction markets. In election-contract litigation, the agency initially fought Kalshi, then voluntarily dropped its appeal after a federal district court allowed the platform to offer contracts tied to U.S. political outcomes. That decision, covered in the CFTC’s dismissal of its Kalshi election-betting appeal, was viewed by Kalshi as a breakthrough for the sector.

But the end of that appeal did not resolve the sports-contract issue. Election markets and sports markets raise different statutory, political and consumer-protection questions. The CFTC’s willingness to reassess its approach has nevertheless strengthened the industry’s argument that prediction markets belong primarily under federal commodities supervision. In later disputes, the agency has supported preemption arguments, including in litigation involving state efforts to regulate sports event contracts.

That support has fueled state frustration. Gaming regulators are accustomed to licensing operators, monitoring integrity risks, enforcing responsible gambling rules and collecting taxes from sports betting activity. A federally regulated exchange model can bypass much of that state apparatus. For states, the concern is not only legal authority but also competitive balance: licensed sportsbooks face compliance costs and tax obligations that prediction platforms say do not apply to them.

Rivals are pushing the same argument

Kalshi is not alone in trying to establish federal preemption. Polymarket has also gone to court, seeking to stop Massachusetts from shutting down its sports event contract markets. In Polymarket’s Massachusetts lawsuit, the company argued that CFTC oversight preempts state gambling enforcement and that its contracts are federally permitted financial instruments rather than sports wagers.

Polymarket’s case followed a Massachusetts decision involving Kalshi that upheld a preliminary ban on sports-event contracts. That sequence shows how one adverse ruling can ripple across the industry. Once a state court or federal court treats a platform’s sports contracts as gambling, rival companies operating similar markets face immediate enforcement risk. Polymarket said Massachusetts’ position created a direct threat to its business, forcing it to choose between asserting federal rights and complying with state restrictions.

Other jurisdictions have moved in the same direction. Nevada regulators have taken the position that sports event contracts are wagers requiring a state gaming license. Polymarket has faced a short-term ban there, while Kalshi has encountered resistance in several states. At the same time, some courts have granted temporary relief to prediction market operators, reinforcing the unsettled nature of the law.

An appeal with industrywide consequences

Kalshi’s New York appeal now sits within a broader national contest over who gets to regulate event-based trading. A win for the company could narrow the ability of state gaming commissions to police sports event contracts when they are offered through federally regulated markets. A loss could accelerate state enforcement and push prediction platforms toward licensing, geofencing or product changes.

The dispute also affects traditional sportsbooks, exchanges, leagues and technology platforms looking at the convergence of trading and wagering. Kalshi and Polymarket recently signed a multiyear partnership with the NHL, giving them access to league data and rights for their platforms. Such deals show that prediction markets are moving from legal abstraction to commercial strategy, with sports leagues and market operators testing new forms of fan engagement.

For courts, the question is narrower but consequential: whether the Commodity Exchange Act displaces state gambling laws when sports outcomes are packaged as event contracts. For regulators, the question is practical: whether consumer activity that resembles betting can be left largely outside state gambling systems because it is routed through a federally supervised market. New York’s case may not settle that conflict nationwide, but the appeal will help determine whether prediction markets gain a clearer path into mainstream sports products or face a state-by-state regulatory wall.
