Coinbase blocks new Ohio sports prediction trades, including combos

Coinbase Financial Markets says Ohio residents and visitors can no longer open new sports positions through its prediction-market service. The company’s eligibility notice gives 12 November as the start date and includes any combo with at least one sports leg.

The restriction applies to orders through Coinbase, where Kalshi operates the underlying markets. A combo that pairs a sports outcome with another event still falls within the restriction described in Coinbase’s notice.

The Ohio Casino Control Commission had told Legal Sports Report that Coinbase had agreed to stop offering the contracts as of 13 November. That account, published on 6 November, followed the commission’s October cease-and-desist letters. Coinbase’s notice gives a date one day earlier and does not specify the hour the restriction took effect.

Coinbase’s trading guide repeats the Ohio restriction without saying whether customers can close existing sports positions early. Prediction Frontier has not independently verified how those positions are being handled.

The Ohio restriction comes as the CFTC’s November interpretation of impartial access requirements asks US exchanges to examine geographic restrictions imposed through brokers and other intermediaries.
