“Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws.” That’s Attorney General Russell Coleman, on June 17, 2026, filing the kind of lawsuit most states in this series haven’t: not a letter to licensees, not a private plaintiff borrowing an old statute, but the state itself suing Kalshi by name. Six days later, the CFTC sued Kentucky right back.

The Sportsbook Market Kentucky Already Built

Kentucky legalized sports betting relatively recently and moved fast. Gov. Andy Beshear signed House Bill 551 on March 31, 2023, making Kentucky the 38th state to legalize it; retail sportsbooks opened September 7, 2023, and mobile betting followed three weeks later. The Kentucky Horse Racing and Gaming Corporation (KHRGC) — renamed from the Kentucky Horse Racing Commission by Senate Bill 299 in 2024 — regulates the market, and licenses flow only through the state’s horse racing associations, each allowed up to three online skins. House Bill 904, passed in April 2026, raised the betting age to 21 statewide and banned college player prop bets. Kalshi holds none of KHRGC’s licenses.

Kentucky’s licensed sportsbook market, at a glance:

  • HB 551 signed March 31, 2023 — 38th state to legalize sports betting
  • Retail launched Sept. 7, 2023; mobile launched Sept. 28, 2023
  • Regulated by the Kentucky Horse Racing and Gaming Corporation (KHRGC)
  • Licenses run only through horse racing associations, up to 3 skins each
  • HB 904 (April 2026) raised the betting age to 21, banned college prop bets
  • Kalshi holds no KHRGC license

Is Kalshi Legal in Kentucky? The State Sued First

On June 17, 2026, Coleman’s office filed Kentucky v. KalshiEX LLC et al. and a companion suit against Polymarket’s QCX LLC in Franklin Circuit Court, plus a third suit against sweepstakes-casino operator VGW — a coordinated push, not a one-off filing. The complaints argue sports event contracts meet Kentucky’s statutory definition of sports wagering, so Kalshi needs a KHRGC license it doesn’t have, and fault the platform for skipping licensed-operator duties like funding problem-gambling resources. That makes Kentucky one of the only states in this series where the attorney general sued Kalshi directly, rather than warning its own licensees or leaving the fight to a private plaintiff.

Kalshi’s answer came fast, and it’s the same one it gives everywhere. A company spokesperson: “The CFTC is our regulator, not the states. Courts have already recognized this, and we’re confident they will here too.”

The CFTC Sued Back

Six days after Coleman’s filing, on June 23, 2026, the CFTC sued Kentucky in the US District Court for the Eastern District of Kentucky, seeking a permanent injunction barring the state from enforcing gambling law against CFTC-designated exchanges. Kentucky became the ninth state the CFTC has sued over prediction-market enforcement — and the first led by a Republican attorney general, a detail that stood out since most earlier CFTC suits targeted Democratic-led states. Layered on top, the legislature passed House Bill 757, taxing prediction-market revenue at 14.25%, and a separate bill barring KHRGC-licensed racing associations from partnering with Kalshi or Polymarket at all, effective July 15, 2026 — both cited in the CFTC’s complaint as evidence of what it calls Kentucky’s campaign to push prediction markets out of the state entirely.

Even the Kentucky Derby Won’t Take the Action

A separate wrinkle, unrelated to the gambling-law fight: neither Kalshi nor Polymarket listed a market on the 2026 Derby winner. Polymarket briefly opened one and pulled it, reportedly at Churchill Downs’ request. That’s not Coleman’s lawsuit at work — it’s the Interstate Horseracing Act, a federal framework that gives track operators intellectual-property control over betting tied to their races. Any platform needs Churchill Downs’ permission before it can list Derby contracts, no matter how the state gambling-law fight turns out.

Is Kalshi Legit in Kentucky?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, dollar settlement, the same starting point as every other state page in this series. A direct lawsuit from a state attorney general is a serious jurisdictional fight, not a finding that Kalshi fails to pay out. It’s a live dispute over which regulator gets the last word, and neither Kentucky’s case nor the CFTC’s has been decided.

Is Kalshi Safe to Use in Kentucky Right Now?

You can open an account and trade from Kentucky today — no injunction currently stops it. But this is one of the more openly hostile states on this site: the attorney general sued directly, the legislature taxed prediction-market revenue at 14.25%, and licensed racing associations are barred from partnering with Kalshi as of July 15, 2026. Safe here still means CFTC oversight and KYC verification, not investment-safe, and not a guarantee that survives however either lawsuit resolves. A contract can expire worthless regardless of who wins in court.
