Ohio moves to enforce sports betting rules against Kalshi after court ruling
Ohio Gov. Mike DeWine says the state will enforce its sports betting laws against Kalshi after a federal appeals court ruling cleared the way for Ohio to regulate the prediction market platform’s sports event contracts.
The dispute centers on whether Kalshi’s sports contracts should be treated as federally regulated financial products or as sports gambling subject to state licensing, taxation and regulatory requirements.
Kalshi Ohio Sports Betting Dispute Moves Forward After Court Ruling
DeWine said on October 2 that Ohio considers Kalshi’s sports-focused prediction markets to be gambling rather than a separate financial-market product.
The governor’s comments followed a September ruling from the U.S. Court of Appeals for the Sixth Circuit involving Kalshi and state regulators. The court upheld an Ohio federal district court decision that had denied Kalshi’s request for a preliminary injunction against state enforcement.
According to the Statehouse News Bureau, DeWine said Ohio would require sports prediction-market operators to follow the same state rules that apply to other regulated sports betting businesses.
The Ohio governor's position is significant because Kalshi has argued that its event contracts fall under federal commodities regulation rather than state gambling laws.
Sixth Circuit ruling opens the door to state enforcement
Kalshi introduced sports event contracts in 2025, allowing users to take positions tied to the outcomes of sporting events.
The Ohio Casino Control Commission subsequently warned the company that its sports products appeared to constitute unlicensed sports betting. Regulators directed Kalshi to stop offering the contracts in Ohio or pursue the state's licensing requirements.
Kalshi challenged the state's position in federal court, arguing that its contracts were federally regulated and that state gambling laws could not be applied to them.
The Sixth Circuit rejected Kalshi's request for preliminary relief. The three-judge panel concluded that Kalshi had not demonstrated that its sports event contracts qualified as “swaps” under the Commodity Exchange Act. The court also held that, even if the contracts qualified as swaps, federal law would not necessarily prevent Ohio and Tennessee from applying their gambling laws.
The ruling therefore allows Ohio to continue pursuing enforcement while the broader legal dispute remains unresolved.
Kalshi faces licensing and tax questions in Ohio
Ohio regulators have treated Kalshi's sports contracts as sports gaming that requires state authorization.
The Statehouse News Bureau reported that the Ohio Casino Control Commission previously instructed Kalshi to comply with Ohio's sports betting licensing framework and associated tax obligations. The commission also imposed a $5 million penalty on Kalshi in April for operating unlicensed sports gaming, according to the report.
RG similarly reported that the commission had pursued enforcement against Kalshi over its sports offerings and that the wider dispute remains in litigation.
The regulatory question is not simply whether consumers can access sports contracts. It also concerns which regulatory system should govern those products and whether prediction-market operators should face requirements similar to licensed sportsbooks.
Why prediction markets are facing greater scrutiny
Prediction markets allow users to trade contracts linked to the outcome of events. Kalshi's platform has offered contracts connected to areas including elections, economic indicators, weather and sports.
Sports contracts have created a particular regulatory challenge because they can resemble traditional wagers while being structured and marketed as event contracts.
The Sixth Circuit's decision focused in part on whether sporting events have the type of inherent financial or economic significance required for contracts to fall within the federal swaps framework. The court found that Kalshi had not established that its sports contracts met that definition.
That distinction could become increasingly important as prediction-market platforms expand into areas traditionally associated with regulated betting.
The case is not yet a final answer on all Kalshi contracts
The latest ruling does not establish that every Kalshi product is gambling under Ohio law.
Instead, the immediate issue was whether Kalshi could prevent Ohio from enforcing its sports gambling regulations while the litigation continued.
The Sixth Circuit ruling gives Ohio room to proceed with state enforcement against the sports offerings. It does not eliminate the broader legal questions surrounding the relationship between prediction markets, federal commodities regulation and state gambling law.
The Statehouse News Bureau reported that the U.S. Supreme Court could ultimately be asked to resolve the wider dispute.
What the Ohio case means for the betting industry
The Kalshi dispute highlights an emerging regulatory question for the global betting and gaming industry: whether sports-related prediction contracts should operate under financial-market rules, gambling regulations, or a combination of both.
For traditional sportsbooks, the distinction can affect licensing, taxation, consumer protections, age restrictions and other compliance obligations.
For prediction-market operators, state classification as sports betting could materially change the regulatory requirements attached to their products.
The case also illustrates how the expansion of prediction markets is creating new points of contact between financial regulation and gambling regulation.
For Asia-Pacific gaming markets, the developments are worth monitoring because regulators in different jurisdictions may face similar questions if event-based trading products expand beyond financial and economic indicators into sports and other entertainment events.
ACN takeaway
Ohio's latest position is clear: state officials intend to treat Kalshi's sports event contracts as subject to Ohio's sports betting framework.
The Sixth Circuit ruling gives the state room to pursue that position while the underlying legal dispute continues. Kalshi, meanwhile, has maintained that its contracts are federally regulated financial products rather than state-regulated sports wagers.
The outcome of the broader litigation could help define where the regulatory boundary sits between prediction markets and sports betting in the United States.
For the wider iGaming industry, the case provides an important regulatory development to watch as prediction markets continue expanding into sports-related products.
