Ohio blocks Kalshi’s sports contracts, calling them gambling

Court rejects swap argument

The ruling came from U.S. District Judge Sarah Morrison after months of legal debate. Judge Morrison denied a request from Kalshi to stop action by the Ohio Casino Control Commission. State officials said the company acted like an unlicensed sportsbook — not a financial service.

Kalshi offers contracts where users trade on future outcomes. These may include politics, economics, or sports results.

Company lawyers argued the contracts should fall under federal derivatives law. They said the deals resemble financial swaps tied to clear events. According to the company, the proper regulator is the Commodity Futures Trading Commission — not state gaming regulators.

State officials support the ruling

Ohio officials reacted soon after the court released its decision. Attorney General Dave Yost welcomed the outcome and backed the regulator’s position. He said prediction contracts tied to sports events appear similar to gambling.

For state officials, the issue centers on oversight and licensing rules. States often control services linked to sports betting. Hence the dispute — one side sees finance, the other sees gaming. The judge’s wording kept the point clear. The contracts resemble wagers on sports outcomes — not financial protection tools.

Kalshi plans to appeal

Kalshi said it plans to appeal the decision in higher courts. The company believes federal derivatives rules may override state gambling laws.

Spokespeople also pointed to a recent court decision in Tennessee. In that case, a court blocked local authorities from applying state rules.

Nevertheless, the wider legal fight continues in several states. Since last year, Kalshi has faced cases from regulators and private groups. These disputes may shape how prediction markets operate in the future.

Prediction markets face regulatory pressure

Prediction markets have existed for many years, though regulators watch them closely. Several well-known services entered this space earlier:

• Intrade

• PredictIt

• Polymarket

• Smartkets

Each service argued that prediction trading offers financial insight — not gambling. Regulators often disagreed. Supporters say these markets may help investors and businesses study future events. 

Global interest continues to grow

Outside the United States, prediction markets draw attention from fintech firms. Many European regulators classify them as gambling and apply strict rules. Malta stands out as a more flexible location for such businesses. In Asia, interest also grows as users follow politics and economic forecasts.

Still, legal rules vary widely between countries. Hence the stakes for Kalshi may reach far beyond Ohio. The court decision could influence how prediction markets fit between finance and gaming — an issue regulators around the world still debate.
