Arizona (USA): all our coverage

The Ohio Casino Control Commission has told every sportsbook, supplier, integrity monitor and testing laboratory it licenses to stop providing services "of any kind" to platforms offering sports event contracts in Ohio, or face reopened suitability investigations. With its cease-and-desist letters to the exchanges now challenged in court, Ohio is turning to the companies that keep them running.

The Federal Register publishes the CFTC's two swap rules on Monday: the exclusion for licensed sportsbooks and casinos is in force that day, and the proposal to define event contracts as swaps opens for comment until 18 November. The rule text says the first changes no one's legal rights, and the second is not yet law.

Kalshi has asked the Ninth Circuit to hold its rehearing petition until the CFTC rewrites its rule on gaming contracts, which the agency says will be final within two months. Nevada's answer is that the court already knew the rule was changing, and that the panel's ruling never depended on it.

The Commodity Futures Trading Commission has asked the White House to clear a rule defining event contracts as swaps, the classification on which its claim to exclusive jurisdiction rests, and a second that would exclude "casino-style gambling products" with immediate effect. Neither text is public, and both arrive days after a second federal appeals court rejected the swaps argument.

The Indian Gaming Association chair told Gaming America that more tribal lawsuits are coming after the Ninth Circuit, that DraftKings' tribal partnerships in Connecticut, Arizona and Washington are at risk over its prediction-market push, and that the Supreme Court will rule against Kalshi. CNIGA's James Siva: "We're keeping track."

Nevada's win against sports event contracts is stayed while the full court decides whether to rehear it, so Arizona, Montana and California cannot enforce, Nevada and Washington do so through state courts, and the Supreme Court's conference is on 28 September.

A federal judge in Utah has ruled against Kalshi's latest attempt to prevent a state from enforcing its gambling laws against the prediction-market operator, extending a string of legal setbacks that have repeatedly undermined the company's federal-preemption strategy at the state level.

The CFTC is no longer just defending prediction markets in court. It is now going on the offensive against the states trying to shut them down. New York is the latest target in a rapidly expanding federal legal campaign.

New York's Attorney General is calling prediction markets what she says they really are: illegal gambling. The lawsuits against two of crypto's biggest names mark a significant escalation in the state versus federal battle over who controls this fast-growing sector.

A congressional hearing has exposed deep uncertainty at the heart of American prediction markets regulation. When the CFTC chair cannot tell a prediction market contract apart from a sportsbook bet, the regulatory gap becomes impossible to ignore.

Washington's derivatives regulator has named the team that will help shape the future of prediction markets, cryptocurrency and AI regulation. The appointments signal where the CFTC's priorities lie.

Kalshi insists its products are financial instruments. State regulators insist they are bets. A Nevada judge has sided firmly with the regulators, and the fight is now playing out in courtrooms across the country.

Arizona Attorney General Kris Mayes has filed 20 criminal misdemeanour charges against prediction market platform Kalshi, alleging it operated an unlicensed gambling business and accepted bets on state elections in violation of Arizona law, marking the first criminal prosecution of a prediction market company by any US state.

Arizona’s regulated sports betting market experienced a predictable seasonal dip in June, with player spending falling to its lowest level in ten months.
