Should prediction markets be allowed to offer sports event contracts to Americans?
Four companies agreed to stop offering sports event contracts in Ohio after the Ohio Casino Control Commission sent cease-and-desist orders to 10 prediction markets and brokers on October 2. Polymarket and Underdog are suing the commission, while Plus500US confirmed compliance on October 21.
Why it matters
The commission's action sets a state-level limit on prediction-market sports contracts that Ohio residents can access through trading platforms. The ongoing lawsuits and remaining negotiations leave open how far state gaming authority extends over these products.
Five of the 10 prediction markets and brokers that received cease-and-desist orders on October 2 have complied so far, including MooMoo Financial, Robinhood, Gemini, and Plus500US. Three companies remain in discussions with the commission, and the commission has not released details on licensee compliance with its October 20 warning.
The players
Ohio Casino Control Commission
The Ohio state agency that regulates casino gaming and oversees licensed gambling activity within the state.
Polymarket
A prediction market platform that lets users trade on the outcomes of future events, including sports results.
Robinhood
A commission-free brokerage platform that offers stock trading and, in some markets, event contracts.
The details
MooMoo Financial, Robinhood, and Gemini no longer offer new sports event contracts in Ohio, and Plus500US was in compliance as of October 21. Polymarket and Underdog have filed lawsuits against the Ohio Casino Control Commission, and Coinbase will stop offering the contracts in Ohio as of November 13.
Timeline
October 2: The Ohio Casino Control Commission sent cease-and-desist orders to 10 prediction markets and brokers.
October 20: The commission warned licensees against providing services to prediction markets.
October 21: Plus500US confirmed compliance with the commission.
November 13: Coinbase will stop offering sports event contracts in Ohio.
Culture Shift
The commission's action extends Ohio's existing sports-wagering oversight to prediction-market contracts, which have grown as an alternative to licensed sportsbooks. Ohio's move reflects a broader state-by-state effort to determine whether these event contracts fall under gambling law.
Ohio residents who trade on platforms like Robinhood or Gemini will no longer find new sports event contracts available on those apps. Users of Coinbase will lose access to the same product starting November 13.
The takeaway
Residents who rely on prediction-market apps for sports contracts should check which platforms still offer them in Ohio before relying on any particular service. Monitoring the pending lawsuits can show whether these restrictions will last.
What happens next
Coinbase will stop offering sports event contracts in Ohio on November 13, and the commission continues discussions with three remaining companies.
