Kentucky Attorney General Russell Coleman announced on Wednesday that his office has filed separate lawsuits against three online platforms he claims are operating without licenses and engaging in illegal sports betting and gambling.
The lawsuits were filed in Franklin Circuit Court against:
Kalshi, a prediction market platform, and its affiliates including Coinbase;
Polymarket, a prediction market platform, and its affiliates; and
VGW, an online casino platform with brands including Chumba Casino, Global Poker, and LuckyLand Slots.
The suits against Kalshi and Polymarket allege that they allow users to place wagers on game winners, point spreads and player statistics, and that they are doing business in Kentucky without a gaming license or following state regulations.
The suit against Kalshi states that it offers so-called “event contracts” on several topics; sports betting made up approximately 70% of its trading volume during a selected sample period in 2025.
The Polymarket suit states that the platform’s flashy advertisements on social media and elsewhere give the false and misleading impression that it is authorized to offer sports wagering under Kentucky law. The platform offers many of the same traditional sports bets as a licensed sportsbook.
“Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws. These multi-billion dollar corporations and their legal fictions don’t pass the sniff test. As one of our state legislative leaders said it best, ‘If it looks like a duck and quacks like a duck’,” said Coleman on the suits.
The suits also allege that each company offers few or no resources to identify or seek help for a gambling problem.
The suit against VGW and its affiliates states that they allegedly operate unlawful sweepstakes casino websites that use two different types of virtual gambling chips.
The games on websites are designed to look and feel like slot machines and blackjack.
The alleged online casinos offer two types of chips: one free and one with cash value.
According to the suit, users pay real money for so-called Sweeps Coins, just as gamblers pay for poker chips at a real casino, or they can cash out their winnings.
“This company may use new technology and a new scheme to hide, but the reality is the same,” Coleman said on the suit. “Our Office has a duty to stop illegal gambling in Kentucky regardless of how it’s packaged.”
In recent months, Coleman has joined in national bipartisan efforts to regulate prediction markets.
