Kalshi has filed a new lawsuit against Ohio regulators. The company wants to stop a planned $5 million fine.
The case was filed on June 29 in the Franklin County Court of Common Pleas. It names the Ohio Casino Control Commission as the target.
The dispute goes back to April. That’s when the commission said Kalshi’s sports contracts count as unlicensed sports betting under state law.
Kalshi disagrees with that view. The company argues its contracts are financial products that fall under federal oversight, not state gaming rules.
Kalshi Seeks a Permanent Injunction
Kalshi is not just asking for a delay. The company wants the court to issue a permanent injunction against the fine.
Its lawyers argue that Ohio’s enforcement process denies Kalshi a jury trial. They say this goes against the state constitution.
The complaint asks the court to declare that any penalty under the relevant law must go through a jury process.
It also asks the court to rule that the law fails to give clear guidance for issuing civil penalties in the first place.
Kalshi’s Head of Communications, Elisabeth Diana, said earlier that the company would protect its interests to the fullest extent the law allows.
This is not the only legal fight Kalshi has faced this year over state sports betting rules. Similar disputes have come up in other states too.
