Kentucky Battles Kalshi, Polymarket in High-Stakes Prediction Market Legal Clash
June 18, 2026
The Kentucky case highlights a regulatory clash over whether prediction markets fall under state sports betting law or federal CFTC jurisdiction, with Kentucky asserting state authority while Kalshi and Polymarket push for federal oversight.
The CFTC has repeatedly pursued action against prediction-market operators and asserts exclusive federal power over these markets, a stance supported by Trump and his allies.
State challenges to prediction markets have faced resistance from the CFTC, which oversees event contracts and has sued other states like Arizona and Minnesota.
A historical reference reminds us of the 2015 PokerStars judgment, where a gambling operator was deemed liable for lost amounts due to fees, establishing a damages framework later cited in disputes here.
The complaints claim the platforms let users wager on game outcomes, point spreads, and player stats, bypassing consumer protections and Kentucky tax and licensing requirements.
Kalshi and Polymarket are private platforms, while Coinbase and Robinhood are the publicly traded exchanges linked to the alleged trading activity in the suit.
Kentucky Attorney General Russell Coleman has filed lawsuits against Kalshi, Polymarket, and VGW, alleging unlicensed and illegal sports betting and gambling in Kentucky.
Coinbase is named for allegedly splitting fees with Kalshi; Robinhood and Webull are mentioned as affiliates of Polymarket.
The suits name Kalshi’s partners Coinbase, Robinhood, and Webull and contend the platforms offer sports event contracts that fall under Kentucky’s licensing definitions for sports wagering.
VGW says it will vigorously defend the lawsuit, stressing its decade-long US operation and commitment to safe, responsible gaming with strong consumer protections.
Polymarket and Kalshi have issued statements defending their operations, while opponents argue the industry seeks to dodge state gaming laws and oversight.
The case includes tensions with notable figures, including critics like Mick Mulvaney and a brief from Gary Gensler arguing Kalshi’s sports betting violates state regulations.
