Ohio Just Moved to License Prediction Markets Like Sports Betting — Here’s What SB 430 Means for Bettors

Ohio has spent the past several months fighting prediction market platforms in court, fining Kalshi $5 million and watching federal judges wrestle with whether those platforms are regulated gambling or federally protected financial instruments. Now, a state senator has introduced a different approach: stop fighting about whether to shut them down and start building the legal architecture to license and tax them instead.

Senate Bill 430, filed by Democratic Sen. Bill DeMora on April 28, 2026, would require prediction market operators offering contracts on Ohio sporting events to obtain a state license and pay taxes under Ohio’s existing sports betting framework. If it passes, platforms like Kalshi, Robinhood, and Polymarket would have to play by the same rules as DraftKings and FanDuel to legally serve Ohio bettors.

What SB 430 Would Actually Do

DeMora’s bill would formally classify trading on sports event contracts as sports wagering under Ohio law. That means any company offering those markets to Ohio residents would need a license from the Ohio Casino Control Commission and would be subject to the state’s 20 percent tax on gross revenues from sports betting activity. To put that number in context, Ohio’s licensed sportsbooks generated over $1 billion in revenue in 2025, producing more than $210 million in tax receipts — the majority of which funds elementary and secondary education in the state.

Under the current system, prediction market platforms argue they operate as CFTC-regulated derivatives exchanges and that federal law preempts any state gambling enforcement. That argument has produced wildly inconsistent results in court. A federal judge in Ohio denied Kalshi’s request for a preliminary injunction in March, ruling that “absurd results would flow” from treating sports event contracts as CFTC-regulated swaps. The U.S. Sixth Circuit Court of Appeals denied Kalshi a further injunction in late April, while simultaneously accelerating the full appeal — meaning Kalshi’s brief is due May 5, Ohio’s response by June 4, and the circuit court ruling could come relatively quickly. A Tennessee judge, meanwhile, reached the opposite conclusion and granted Kalshi an injunction, deepening what is increasingly looking like a circuit split headed for the Supreme Court.

DeMora, the lead Democrat on the Ohio Senate Select Committee on Gaming and one of the more experienced state legislators on gambling matters, has been direct in his assessment of the industry. He views Kalshi as “a sham” on the grounds that its sports markets are functionally identical to sports betting. His bill is designed to give Ohio a workable framework if the Supreme Court ultimately rules in the platforms’ favor — rather than leaving the state scrambling to build one from scratch after the fact.

Why This Matters for Ohio Bettors

For bettors in Ohio, the current situation creates a genuinely uneven playing field. Licensed sportsbooks like DraftKings and FanDuel operate under the OCCC’s oversight and must follow specific rules — including a prohibition on certain college athlete prop bets that Ohio passed several years ago. Prediction market platforms currently serving Ohio have no obligation to follow those same rules. If they operate as federally licensed derivatives exchanges, state restrictions on market types simply do not apply to them.

SB 430 would close that gap. A licensed prediction market in Ohio would be required to comply with the same consumer protection standards, responsible gambling requirements, and market restrictions that apply to every other licensed operator in the state. The bill would also capture tax revenue from platforms that have been generating substantial Ohio trading volume while contributing nothing to the state’s education fund.

The Bigger Picture: Ohio as a National Template

Ohio is not the only state thinking along these lines. Illinois introduced SB 4168 in March, which would similarly require prediction market platforms to obtain state licenses and pay Illinois gaming taxes. New Jersey has considered legislation requiring sports event contracts to operate under the state’s existing sports betting regulatory framework. Iowa’s Senate passed Senate File 2470 in a 45-1 vote that would create a comprehensive licensing and taxation system for prediction markets — making it the first legislative chamber in the country to pass a regulate-and-tax bill rather than a ban.

What distinguishes Ohio’s approach is the context: the OCCC has already issued a $5 million proposed fine against Kalshi, the state has won in federal court, and litigation is actively moving through the Sixth Circuit. Introducing a licensing framework now signals that Ohio is prepared for multiple outcomes — including one where the federal courts eventually side with the platforms. If prediction markets are going to operate in Ohio regardless of what the state does in court, SB 430 ensures Ohio gets paid while they do it.

Whether the bill advances through the Senate and reaches a floor vote will depend on how the courts move over the next several months. The Sixth Circuit’s accelerated timeline means a ruling could come before the Ohio legislative session ends, which would dramatically reshape the political calculus around the bill in either direction. For now, bettors in Ohio should watch both the courtrooms and the committee rooms.
