The Backstory

Prediction markets push into gambling’s regulatory fault line

The fight over sports event contracts has moved quickly from a niche financial-markets dispute to one of the most consequential regulatory questions facing U.S. gaming. At issue is whether platforms such as Kalshi can offer contracts tied to sports outcomes under federal commodities oversight or whether those products amount to sports betting that must comply with state gambling laws.

The distinction matters because U.S. sports betting has been built around state-by-state licensing, taxation, consumer-protection rules and integrity controls since the Supreme Court struck down the federal ban on expanded sports wagering in 2018. Prediction market operators argue they are offering federally regulated financial products, not wagers. State regulators and gaming officials counter that a contract paying out based on the result of a game functions like a sports bet, regardless of the legal label attached to it.

The latest request by the North American Gaming Regulators Association and the International Association of Gaming Regulators for Supreme Court review reflects growing alarm among regulators that the courts are now producing divergent answers to the same question. Their intervention follows a series of rulings and petitions that have created uncertainty over where federal commodities law ends and state gambling authority begins.

New Jersey’s loss created the first major opening

The legal clash accelerated after New Jersey sought to apply its sports betting rules to Kalshi’s sports-related event contracts. In April, the 3rd U.S. Circuit Court of Appeals sided with Kalshi at a key stage of the case, finding that the company was likely to prevail on its claim that federal law preempts state regulation of the products. The court concluded that the Commodity Futures Trading Commission had exclusive jurisdiction over the contracts because they fell within the federal framework governing swaps.

That ruling prompted New Jersey Attorney General Jennifer Davenport to ask the Supreme Court to intervene. In a 332-page petition seeking review of Kalshi sports markets, the state argued that sports event contracts should be treated as sports betting and subject to state requirements including licensing, age controls and other regulatory safeguards.

New Jersey’s petition framed the dispute as more than a disagreement with one platform. The state warned that accepting Kalshi’s theory could allow sports wagering to be conducted outside the gaming-law structure that states have developed over years. More than 40 states have opposed Kalshi’s position, according to the filing described in the related coverage, underscoring the breadth of concern across jurisdictions with different political and gambling-policy approaches.

Kalshi has maintained that its contracts are financial instruments regulated by the CFTC under the Commodity Exchange Act, not gambling products. That position, if accepted nationally, would provide a route for event-contract platforms to operate under a single federal regulator instead of securing approvals from individual state gaming agencies.

Conflicting appeals courts raised the stakes

The dispute became more urgent when other federal appeals courts declined to follow the 3rd Circuit’s reasoning. In August, the 9th U.S. Circuit Court of Appeals in San Francisco rejected Kalshi’s attempt to block enforcement by Nevada regulators. The court agreed that the CFTC has exclusive authority over swaps but found no clear congressional authorization to transform sports wagers into federally protected swaps beyond state gambling oversight.

That split increased the likelihood of Supreme Court review because regulated companies, state agencies and gaming operators now face different legal rules depending on geography. Kalshi can point to the 3rd Circuit’s New Jersey decision as support for federal preemption, while states can rely on the 9th Circuit’s Nevada ruling as support for enforcement of gambling laws.

The division deepened further when the 6th U.S. Circuit Court of Appeals ruled that Ohio and Tennessee could enforce their gambling laws against Kalshi. In a decision rejecting Kalshi’s bid to block state regulation of prediction markets, the court unanimously rejected the company’s argument that its sports event contracts were insulated from state oversight as federally governed swaps. The panel said that even if the contracts qualified as swaps, the Commodity Exchange Act would not bar states from applying gambling regulations.

That ruling combined disputes from Ohio and Tennessee. Ohio regulators had issued Kalshi a $5 million fine for allegedly offering unlicensed sports betting. Tennessee had sought to continue enforcement after a lower court temporarily blocked action against the company. Together, the cases illustrated the growing enforcement pressure facing prediction markets as more states treat sports event contracts as illegal or unlicensed betting.

Lawmakers and regulators converge on the same concern

The regulatory response has not been limited to enforcement agencies. The National Council of Legislators from Gaming States also urged the Supreme Court to hear the dispute, warning that a decision limiting state authority could destabilize gambling laws across the country. In its amicus brief urging review of the Kalshi case, the group said other gambling operators could try to reclassify products to avoid state oversight if prediction markets prevail.

That concern goes to the core of the policy debate. States have long asserted authority over gambling because the activity carries risks that include underage participation, addiction, match integrity threats, money laundering and improper participation by athletes, coaches or insiders. Sports betting laws typically include minimum age rules, self-exclusion programs, licensing scrutiny, tax obligations, data requirements and monitoring for suspicious wagering.

Prediction market advocates argue that federal oversight is more appropriate for standardized contracts traded across state lines. They say state-by-state regulation creates fragmentation and uncertainty, especially for markets designed to function nationally. Kalshi has made that point directly, saying the patchwork of conflicting rulings shows why Congress created a single federal regulator for commodities markets.

For state regulators, however, the risk is that sports betting could migrate into a federally supervised channel without the consumer and integrity protections required of licensed sportsbooks. The amicus efforts by regulators and lawmakers therefore reflect a broader concern that legal classification could determine not only which agency supervises a product but whether a major category of sports wagering bypasses state gambling systems altogether.

IAGR’s role reflects a broader push for coordination

The International Association of Gaming Regulators’ participation in the Supreme Court push also fits a wider effort to strengthen cross-border regulatory coordination. Earlier this year, the organization appointed Kevin Mullally as its first chief executive, a move described as part of an effort to enhance cooperation on shared challenges across jurisdictions. Mullally brought experience in U.S. gaming regulation, public policy, governance and international regulatory development, including prior leadership roles tied to Missouri, Gaming Laboratories International and the United Arab Emirates.

His appointment, detailed in coverage of Kevin Mullally joining IAGR as its first chief executive, signaled that the association saw a need for more permanent operational capacity as regulators confront increasingly complex issues. Prediction markets are a prime example: They sit at the intersection of financial law, sports wagering, consumer protection, technology and interstate commerce.

IAGR has also expanded its institutional work through committees and working groups focused on technology, model rules and illegal gambling. That agenda was reinforced when Gaming Associates became a Titanium Sponsor, supporting the group’s conference, regulatory initiatives and education programs. The sponsorship arrangement with Gaming Associates was presented as backing for IAGR’s efforts to promote consistency in regulatory processes and help regulators align policy approaches.

Those developments help explain why IAGR joined NAGRA in the Supreme Court filing. The Kalshi litigation is not merely a U.S. procedural dispute; it is a test of how regulators respond when technology and legal engineering allow gambling-like products to emerge outside traditional licensing channels. For international regulators, the outcome could influence how other markets classify event-based financial products and how quickly operators seek to replicate models across borders.

A Supreme Court decision could redraw the map

If the Supreme Court takes the case, it could settle whether sports event contracts fall exclusively within federal commodities oversight or remain subject to state gambling law when tied to athletic contests. A broad ruling for Kalshi could weaken states’ ability to police sports wagering packaged as event contracts. A ruling for New Jersey and other states could require prediction markets to comply with gambling rules where their products function as bets.

The stakes extend to tribes, licensed sportsbooks, state tax systems and consumers. Tribal gaming compacts often depend on defined categories of gambling activity and state enforcement boundaries. Licensed operators have invested heavily in compliance systems and market access under state law. Consumers may face different protections depending on whether a product is governed as a financial contract or a wager.

That is why the current wave of amicus briefs matters. Regulators and lawmakers are asking the court not just to resolve an industry dispute but to clarify the boundary between two regulatory regimes. Until that happens, prediction markets, gaming regulators and state officials will continue operating in a fractured legal environment where the same sports contract may be treated as a federally protected derivative in one circuit and unlicensed gambling in another.
