Kalshi Missouri: The AG Who Didn’t Sign the Letter

Kalshi Missouri sits next to one of the newest licensed sportsbook markets in the country and, so far, no fight at all. Missouri’s Gaming Commission only started regulating real-money sports wagering in December 2025, and when 44 state attorneys general sent the CFTC a joint letter in July 2026 arguing it has no authority over sports event contracts, Missouri’s was one of just five signatures missing. This page covers what that omission does and doesn’t mean.

Legal status in Missouri

Missouri voters approved Amendment 2 in November 2024 by a margin of roughly 2,961 votes, legalizing retail and online sports wagering and requiring licensed betting to be available statewide no later than December 1, 2025 — a deadline the market hit, with FanDuel and other operators launching that day. The Missouri Gaming Commission (MGC) regulates the market: up to 21 total licenses are authorized, split between the state’s 13 licensed casinos, six professional sports franchises, and two "untethered" licenses not tied to an existing casino or team, with as many as 14 of those licenses covering mobile and online betting. Operators pay a 10% tax on adjusted gross revenue, split between public education and a compulsive-gambling fund. Kalshi holds none of those MGC licenses and doesn’t apply for them, operating instead under its federal CFTC designation — the same theory it runs in every state. Missouri has taken no public action against Kalshi: no cease-and-desist letter, no lawsuit, no MGC statement naming the platform. More notable is what Missouri didn’t do at the federal level. On July 28, 2026, a coalition of 44 state attorneys general, led by Ohio’s Andy Wilson, told the CFTC in a joint comment letter that it lacks authority to regulate sports-related event contracts. Missouri Attorney General Catherine Hanaway — who took office September 8, 2025 after Andrew Bailey left for a Trump administration FBI post — was one of only five state AGs who did not sign, alongside Texas, Florida, Georgia, and New Hampshire. That is not a small thing to skip: it is the single largest coordinated state action against Kalshi’s core product to date, and Missouri opted out of it. As of this writing, no Missouri court or agency has ruled on whether the MGC’s sports-wagering statute reaches Kalshi’s contracts at all.

State gambling authority: Missouri Gaming Commission (sportsbooks only — no formal position on Kalshi)

In July 2026, 44 state attorneys general sent the CFTC a joint letter arguing it has no authority over sports event contracts — the biggest coordinated state move against Kalshi’s core product to date. Missouri’s signature wasn’t on it. Neither was Texas, Florida, Georgia, or New Hampshire’s. Everyone else signed.

A Sportsbook Market That’s Barely Out of the Gate

Missouri voters approved Amendment 2 in November 2024, by a margin of roughly 2,961 votes — close enough that a recount was floated before the result held. The amendment set a hard deadline: licensed sports wagering, retail and online, had to be live statewide no later than December 1, 2025. The market hit it, with FanDuel and other operators launching that day. The Missouri Gaming Commission now oversees up to 21 licenses — 13 tied to the state’s existing casinos, six to professional sports franchises, and two “untethered” licenses open to operators without a casino or team tie — with as many as 14 of those covering mobile betting, taxed at 10% of adjusted gross revenue. Kalshi holds none of it and isn’t applying for it, relying instead on its federal CFTC designation.

Missouri’s licensed sportsbook market, at a glance:

Amendment 2, approved November 2024 by ~2,961 votes
Statewide launch deadline: December 1, 2025 — met on time
Up to 21 MGC licenses: 13 casino-tied, 6 team-tied, 2 untethered
Up to 14 licenses cover mobile/online wagering
10% tax on adjusted gross revenue, split toward education and a compulsive-gambling fund

Is Kalshi Legal in Missouri? The AG Who Didn’t Sign

No Missouri agency has sent Kalshi a cease-and-desist letter, filed suit, or issued a public ruling on whether the MGC’s sports-wagering statute reaches its contracts. That much puts Missouri alongside quieter states like Indiana and Virginia. What sets it apart is the federal letter. On July 28, 2026, Ohio Attorney General Andy Wilson led a coalition of 44 state AGs telling the CFTC it lacks authority over sports-related event contracts — essentially every state but five. Missouri Attorney General Catherine Hanaway, who took office in September 2025 after Andrew Bailey left for a federal post, did not add her name. Neither did Texas, Florida, Georgia, or New Hampshire.

Opting out isn’t the same as endorsing Kalshi. Hanaway’s office hasn’t explained the decision publicly, and declining to sign a coalition letter is not a ruling that Missouri law permits Kalshi’s contracts. It just means Missouri chose not to join the loudest collective state argument against the CFTC’s position — for reasons that, so far, are Missouri’s alone.

A Very Different Gambling Fight, Same Attorney General

Hanaway’s silence on Kalshi isn’t inattention to gambling law generally. Through 2026 her office has run one of the more aggressive state gambling crackdowns in the country — aimed at unregulated, slot-style “no-chance” terminals scattered through gas stations and bars, supplied largely by Torch Electronics. A federal judge found in February 2026 that the devices qualify as illegal gambling machines outside licensed casinos; enforcement cut the estimated statewide count from roughly 25,000 machines to about 7,000 by March, and Torch agreed to suspend operations that April. Missouri businesses sued over her authority to force that in June 2026. It’s a real fight, with real casualties for one company — just not Kalshi’s.

Is Kalshi Legit in Missouri?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, dollar settlement, the same starting point every state page in this series opens from. Missouri not signing the AG letter doesn’t change that calculus any more than Indiana’s or Georgia’s silence does; it just means no Missouri agency has staked out a position on Kalshi specifically, favorable or otherwise.

Is Kalshi Safe to Use in Missouri Right Now?

You can open an account and trade from Missouri today, with no cease-and-desist and no lawsuit pointed at Kalshi in either direction. Safe here still means CFTC oversight and KYC verification — not investment-safe. A contract can expire worthless no matter what any state ultimately decides, and Missouri’s newly licensed sportsbooks carry MGC consumer protections that Kalshi, operating outside that permit system, isn’t required to match.

Kalshi Missouri — Frequently Asked Questions

Is Kalshi legal in Missouri?

Nothing in Missouri currently blocks it. The Missouri Gaming Commission licenses sportsbooks under Amendment 2, but that framework has never been applied to Kalshi in a cease-and-desist letter, a lawsuit, or an MGC ruling. Missouri also declined to join the 44-state attorneys general letter arguing the CFTC has no authority over sports event contracts. Operating without challenge is not the same as a state agency clearing it.

Why didn’t Missouri sign the 44-state letter against Kalshi?

Attorney General Catherine Hanaway’s office hasn’t published a public explanation, and Missouri joined Texas, Florida, Georgia, and New Hampshire as the only states that skipped it. What makes the omission notable is timing: Hanaway spent much of the same year running one of the most aggressive gambling-enforcement campaigns in the country, just aimed at a different target — unregulated slot-style machines, not Kalshi.

Does Missouri’s crackdown on gambling machines have anything to do with Kalshi?

No — it’s a separate fight, but it shows Hanaway isn’t passive on gambling issues generally. Her office’s campaign against unlicensed "no-chance" slot-style terminals, run by companies like Torch Electronics, cut the estimated statewide machine count from roughly 25,000 to about 7,000 by March 2026 and pushed Torch to suspend operations that April. Missouri businesses sued over her authority to do that in June 2026. None of it touches Kalshi, which is a federally regulated exchange, not a slot-style terminal — but it undercuts the idea that Missouri simply isn’t paying attention to gambling law.

Is Kalshi legit in Missouri?

As a company, yes — CFTC designation since 2020, KYC-verified accounts, dollar settlement, the same baseline that applies in every state on this site. Missouri’s silence, and its choice not to sign the AG coalition letter, isn’t evidence either way on legitimacy; it just means no Missouri agency has taken a public position on Kalshi specifically.

Is Kalshi safe to use in Missouri right now?

You can open an account and trade from Missouri today with no cease-and-desist and no injunction in either direction. Safe here means CFTC oversight and KYC verification — it does not mean investment-safe. A contract can expire worthless regardless of how any state’s legal position eventually shakes out, and Missouri’s newly licensed sportsbooks carry MGC consumer protections that Kalshi, sitting outside that permit system, isn’t required to match.

Does Missouri’s new sportsbook market compete with Kalshi?

They’re selling different products to the same attention. Missouri’s MGC-licensed sportsbooks — FanDuel and others that launched December 1, 2025 — take traditional bets against the house at a 10% state tax on revenue. Kalshi lists Yes/No event contracts priced as probabilities under a federal exchange model. A Missouri bettor could use either, or both, but they run on entirely separate legal frameworks.
