Trump Administration and CFTC Sue Three States Over Prediction‑Market Gambling Rules After Cease‑and‑Desist Orders and Arizona Criminal Charges
The Trump administration, suing on behalf of the CFTC, filed federal lawsuits against Connecticut, Arizona and Illinois to block state cease-and-desist orders that treat prediction‑market platforms such as Kalshi and Polymarket as illegal gambling — a dispute that escalated after Arizona also brought criminal charges against Kalshi, including under a ban on betting on elections. CFTC Chair Michael S. Selig vowed to defend the agency’s exclusive authority and market participants, while platforms say their event‑contract futures belong under CFTC rulemaking, tribal gaming groups have condemned the products as unlawful gambling and urged congressional action, and state officials like Connecticut’s attorney general promise to defend consumer‑protection laws — a conflict experts say may eventually reach the Supreme Court.
📌 Key Facts
- The Trump administration filed three federal lawsuits in early April 2026 against Illinois, Connecticut and Arizona seeking to block those states from applying state gambling laws to prediction markets; the suits were brought on behalf of the Commodity Futures Trading Commission (CFTC).
- The CFTC’s legal position is that prediction‑market contracts are 'swaps' or event‑futures that fall under the commission’s exclusive federal regulatory authority, and it points to its ongoing rulemaking as the proper forum for oversight.
- CFTC Chair Michael S. Selig vowed the agency would 'safeguard the CFTC’s exclusive regulatory authority' and defend market participants from what he called 'overzealous state regulators.'
- All three states issued cease‑and‑desist orders accusing platforms such as Kalshi and Polymarket of illegal online gambling under state law; Arizona separately filed criminal charges against Kalshi in March 2026, including an allegation of violating a law barring bets on elections.
- Platforms including Kalshi, Polymarket and Robinhood insist their products are futures‑style 'event contracts' subject to CFTC oversight rather than state gambling regulation, and have urged regulators to resolve issues through the CFTC rulemaking process.
- The Indian Gaming Association and tribal leaders have strongly opposed prediction markets, calling them 'unlawful gambling dressed up as finance,' urging Congressional action, and creating a defense fund to support legal challenges—citing threats to tribal gambling revenue that funds health, housing, education and other services.
- Connecticut Attorney General William Tong responded on the record by accusing the federal government of 'recycling industry arguments' and pledging to vigorously defend state consumer‑protection laws.
- Legal experts say the federal lawsuits escalate the conflict between state and federal regulators and increase the likelihood the Supreme Court will ultimately have to decide whether prediction markets are regulated financial instruments or illegal gambling.
