Ohio Prepares Further Legal Action Against Prediction Markets
United States.- 21 October 2026 | www.zonadeazar.com The US state of Ohio has announced plans to intensify legal action against prediction market platforms offering contracts linked to sporting events.
Governor Mike DeWine confirmed that state authorities intend to enforce gambling legislation against operators including Kalshi, Polymarket and Robinhood.
The announcement deepens an ongoing dispute between state gambling regulators and companies that maintain their event contracts fall under federal financial supervision.
Ohio Challenges Sports Event Contracts
The Ohio Casino Control Commission has already issued cease-and-desist notices to several prediction market operators.
State authorities argue that certain sports-related contracts constitute gambling products and should therefore be subject to the same requirements as licensed sportsbooks.
These obligations include:
- Obtaining a state sports betting licence.
- Enforcing a minimum gambling age of 21.
- Paying the 20% state tax on sports betting revenue.
- Implementing consumer protection measures.
- Complying with restrictions on certain betting markets.
DeWine has questioned why prediction market platforms should be permitted to offer sports contracts without meeting the requirements imposed on regulated betting companies.
Kalshi Defends Federal Oversight
Kalshi argues that its event contracts are regulated by the Commodity Futures Trading Commission (CFTC) under US federal derivatives legislation.
However, a recent decision by the US Court of Appeals for the Sixth Circuit allowed Ohio to continue enforcing certain state gambling provisions.
The ruling provides an important legal precedent for proceedings involving other prediction market operators.
At the centre of the dispute is whether federal supervision prevents states from applying gambling laws or whether both regulatory frameworks can operate alongside each other.
Two Bills Seek Stronger Regulation
Ohio lawmakers are also considering two legislative proposals addressing prediction markets.
Senate Bill 479: would prohibit election betting and prevent prediction market platforms from offering contracts related to electoral outcomes.
Senate Bill 430: would classify sports event contracts as sports gambling, bringing them under state licensing, regulation and taxation.
Neither proposal has made significant progress through the legislature.
Consumer protection concerns are also part of the debate, particularly because certain prediction markets allow participation from 18 years of age, compared with Ohio’s minimum legal age of 21 for traditional sports betting.
Next Steps and Impact
Governor DeWine has emphasised that Ohio will move beyond issuing warnings and pursue legal action against operators it considers to be violating state gambling laws.
The dispute could influence prediction market regulation in other US states facing similar jurisdictional challenges.
For the iGaming industry, the case highlights a major regulatory issue: defining the legal boundaries between conventional sports betting and financial contracts linked to future events.
The outcome of these proceedings will be important in determining the conditions under which platforms such as Kalshi and Polymarket can continue offering sports-related products across the United States.
