What changed (newest first)

Ohio's Established Sports Betting Market

To understand the OCCC's aggressive posture, one must look at Ohio's massive and highly regulated sports betting industry. The state went live with both mobile and retail sports betting on January 1, 2023, and quickly became one of the nation's largest markets. Major operators including FanDuel, DraftKings, BetMGM, and Caesars are all active, having paid for licenses and agreeing to a 10% tax on revenue.

State regulators and licensed operators view Kalshi's sports markets as an unlicensed competitor attempting to circumvent these established rules. The OCCC's mandate is to protect the integrity and fairness of this licensed market, and it sees unregulated offerings as a direct threat to that mission (and to state tax revenues).

What Ohio Residents Can Trade Right Now

Ohioans using these platforms can still trade on a wide array of event contracts. The primary area of legal contention is markets based on sports outcomes. While these markets may still be visible and tradeable on a platform like Kalshi, users should be aware of the significant risk associated with them.

However, the Ohio court ruling and OCCC fine are narrowly focused on sports. Markets on other topics are not currently affected. These include:

  • Political Outcomes: Contracts on election results, legislative actions, and political appointments.
  • Economic Events: Markets based on inflation rates (CPI), Federal Reserve interest rate decisions, jobs reports, and other economic data.
  • Climate and Weather: Contracts based on temperature, rainfall, or hurricane landfalls.

Trading in these non-sports categories does not appear to be challenged by the state of Ohio at this time.

Tax Considerations for Ohio Residents

Winnings from prediction markets are considered taxable income by the IRSโ†— (opens in a new tab) and the Ohio Department of Taxation. Regardless of the legal status of the platform you use, you are required to report any net profits as "other income." Kalshi provides a profit-and-loss statement for your trades (its 1099s cover interest, rewards and crypto transfers), so keep your own records.

It is crucial to keep accurate records of your trades, including deposits, withdrawals, wins, and losses. We recommend consulting with a tax professional in Ohio to ensure you are meeting all your federal and state tax obligations.

What could change the status

Dates we are watching: Nevada's responses to the Robinhood and Crypto.com Supreme Court petitions are now due November 13 and 16, 2026 (both extended in October), and Kalshi's response to New Jersey's petition is due November 9, 2026 (deadlines can be extended); the earliest the Supreme Court could act on the petitions is a conference in December 2026 or January 2027 (our estimate, not a scheduled date). We re-check this page when any of these happen and log the change above.
