Ohio Warns Gaming Licensees Over Prediction Market Ties as Regulatory Pressure Grows

Key Highlights

Ohio’s gambling regulator is elevating its enforcement of event contracts, warning that legal sportsbooks that work with unlicensed prediction markets could lose their Ohio gaming license.

Ohio Warns Sportsbooks & Suppliers Over Prediction Market Ties

The Ohio Casino Control Commission (OCCC) issued the warning following a meeting on October 20 amid a series of legal battles nationwide involving prediction markets. The cease-and-desist notice follows an earlier order to 10 prediction market operators, including Coinbase, Novig, Polymarket, and Robinhood Derivatives. Its latest move targets a broad range of companies that serve platforms offering sports event contracts without an Ohio sports gaming license.

The OCCC identified support including market making, liquidity services, integrity monitoring, data security, and other technology work. It instructed licensees to stop supporting affected platforms immediately and confirm compliance by October 30. Those that fail to comply could face license denial, suspension, nonrenewal, or revocation.

The warning may affect major sportsbooks such as DraftKings, FanDuel, and Fanatics, plus suppliers including Genius Sports, Sportradar, and IC360. The OCCC has not said these businesses will lose their licenses. Instead, its notice sets out possible consequences for license holders with prohibited prediction market ties; notably, DraftKings launched a companion DraftKings Predictions platform in December 2025.

Ohio Prediction Market Dispute & Legal Challenges

Ohio’s warning follows earlier action against sports event contracts offered through prediction markets. The OCCC’s initial cease-and-desist notices were issued on October 2, giving the 10 companies until October 16 to stop offering the contracts. With that deadline now passed, the regulator intends to act against businesses that did not comply.

The dispute involves federal and state authority over these sports event contracts. The commission pointed to a September ruling from the Sixth Circuit, which found that sports event contracts were not swaps and that federal law did not override Ohio’s gambling rules. That decision supports the state’s position as it challenges companies offering such contracts.

Prediction market operator Polymarket has also sued Ohio over its sports betting laws. The legal fight adds uncertainty for companies operating in this area, particularly those with relationships across sportsbooks and new prediction platforms. For licensed suppliers, the immediate issue is whether their existing services could trigger action from Ohio regulators.

Regulatory Warning Raises Questions for Sportsbooks & Suppliers

Ohio’s warning could create challenges for licensed sportsbooks and technology suppliers that also work with prediction market platforms. Companies operating in both sectors may need to review their business relationships to avoid violating state gaming rules. Even services that don’t involve directly offering sports contracts could raise regulatory concerns.

The commission’s position puts pressure on businesses to decide which partnerships they can maintain. Suppliers providing trading support, market data, or technology services may need to change their agreements with prediction market operators. Failure to meet Ohio’s requirements could put their existing gaming licenses at risk.

The October 30 compliance deadline gives affected companies a clear date to address these concerns. However, ongoing legal challenges could shape how prediction markets are regulated in Ohio and other states. For now, the commission’s warning signals closer scrutiny of businesses connecting traditional sports betting with prediction markets.
