Ohio’s gambling oversight agency has formally notified prediction market leader Kalshi of its intent to impose a $5 million fine, marking a sharp escalation in the state’s crackdown on unlicensed sports-related trading. The Ohio Casino Control Commission (OCCC) issued the notice Tuesday afternoon to KalshiEX LLC, accusing the company of offering services that amount to illegal sports betting through its binary event contracts.
Regulators argue that these contracts allow Kalshi to function as an unlicensed sports wagering operator, violating state law.
The commission, which oversees casinos, sports betting, skill-based machines, and fantasy contests, stressed its duty to enforce compliance and protect the integrity of sports gaming in Ohio.
“The Commission takes its regulatory responsibilities to ensure compliance with the law and the integrity of sports gaming in Ohio seriously,” the agency stated.
The move comes amid a broader dispute over whether prediction platforms qualify as gambling. Kalshi and similar firms insist their products are not bets but federally regulated contracts.
However, an Ohio court recently blocked Kalshi’s effort to prevent state enforcement, and the state attorney general has signaled that the company could face expulsion from Ohio if it continues operating without a license.
The penalty stems directly from Kalshi’s refusal to suspend its controversial binary sports contracts.
It follows by just over a month a federal judge’s denial of the company’s request to bar the OCCC from treating those contracts as sports betting.
That ruling rejected Kalshi’s core legal argument: that federal oversight by the Commodity Futures Trading Commission (CFTC) preempts state authority. Kalshi holds CFTC approval to offer event contracts on sports, weather, entertainment, finance, and politics.
In its notice, the OCCC warned that by operating without a license, Kalshi has blocked regulators from reviewing the company’s and its executives’ suitability.
Authorities also lack confirmation that the platform follows Ohio’s required consumer safeguards and operational guardrails.
Prediction markets have exploded in popularity over the past year, especially after NFL contracts went live.
Industry estimates cited by the FT now suggest Kalshi’s sports trading could generate $1.3 billion in annualized revenue—roughly one-fifth of DraftKings’ projected 2026 total—with sports contracts accounting for about 90 percent of the firm’s overall business.
The case highlights growing tension between innovative, CFTC-sanctioned financial products and state gambling laws.
While prediction platforms position themselves as modern alternatives to traditional betting, Ohio officials maintain that sports-focused contracts fall squarely under their regulatory purview. Kalshi has not yet commented publicly on the latest action, but the standoff is likely to continue in both regulatory and legal aspects.
