Trump Administration and CFTC Sue Three States Over Prediction‑Market Gambling Rules After Cease‑and‑Desist Orders and Arizona Criminal Charges
On Thursday the Trump administration, on behalf of the Commodity Futures Trading Commission, sued Connecticut, Arizona and Illinois to block state cease‑and‑desist orders that treated prediction‑market platforms such as Kalshi and Polymarket as illegal gambling, arguing those event contracts are swaps subject to the CFTC’s exclusive authority; Arizona has also filed criminal charges against Kalshi alleging violations of state gambling and election‑betting laws. The lawsuits have escalated clashes with tribal gaming interests and state officials—CFTC Chair Michael S. Selig vowed to defend the agency’s exclusive oversight while Connecticut Attorney General William Tong rejected the move as recycling industry arguments—raising the prospect the Supreme Court may ultimately have to decide whether prediction markets are finance or gambling.
📌 Key Facts
- On April 2, 2026 the Trump administration filed three federal lawsuits against Illinois, Connecticut and Arizona seeking to block those states from applying state gambling laws to prediction markets.
- The lawsuits, brought on behalf of the Commodity Futures Trading Commission (CFTC), argue that prediction markets are 'swaps' and therefore fall under the CFTC’s exclusive federal regulatory authority rather than state gambling regulators.
- CFTC Chairman Michael S. Selig said the agency will safeguard its 'exclusive regulatory authority,' defend market participants against 'overzealous state regulators,' and criticized a 'fragmented patchwork' of state rules.
- All three states had issued cease‑and‑desist orders accusing operators such as Kalshi and Polymarket of illegal online gambling under state law; Arizona also filed criminal charges against Kalshi in March 2026, alleging state gaming-law violations and a ban on betting on elections.
- Platforms including Kalshi, Polymarket and Robinhood maintain their products are futures-style 'event contracts' that should be regulated by the CFTC and point to the agency’s ongoing rulemaking as the proper forum.
- The Indian Gaming Association and tribal leaders say prediction markets threaten tribal casinos; chairman David Bean called them 'unlawful gambling dressed up as finance,' the association urged Congress to act and set up a defense fund, noting tribal gambling generates more than $40 billion a year for healthcare, housing, education and other services.
- Legal experts say the federal suits escalate the conflict between federal and state regulators and increase the likelihood the Supreme Court will ultimately have to decide whether prediction markets are finance (subject to CFTC oversight) or unlawful gambling.
- Connecticut Attorney General William Tong responded on record accusing the Trump administration of 'recycling industry arguments' and vowed to defend the state’s consumer‑protection laws.
