Maine's regulator says it is monitoring the use of AI "locally and nationally" after the New York Times report on DraftKings, which takes about four in every five dollars bet with the state's mobile sportsbooks. Its draft rules for online casino, the product at the centre of the Times investigation, are open for comment until 30 October.

Ohio's governor has called prediction markets "really gambling, nothing more than that" and promised enforcement after the Sixth Circuit ruled for the state. The commission's proposed $5 million penalty against Kalshi has been pending since April, and Kalshi says the ruling will not survive further review.

On the opening main stage at G2E, the chief executives of MGM Resorts and Caesars called prediction markets illegal, "obscene" and a risk to the whole industry. Wynn Resorts' Craig Billings said his company had no "skin in the game", and recalled what the Strip lost by fighting California's tribes.

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.

A proposed class action filed in Boston accuses DraftKings of using customers' data to find the gamblers most likely to lose, then sending them more offers, in breach of its own privacy promises. It leans heavily on the New York Times investigation, and DraftKings says it does not use AI that way.

Federal prosecutors say contracts on the capture of Nicolás Maduro "are inherently economic" and so qualify as swaps, whatever two appeals courts have said about Kalshi's sports contracts. The question decides whether the first insider-trading prosecution over prediction-market trades survives, and argument is set for 7 October.

Notices filed with Washington's Employment Security Department put eight of Maverick's card rooms on course to close at the end of November, on top of two in Tukwila on 1 November. The company says a buyer in its Chapter 11 case could keep some open, and one Pasco councilman says that is already happening.

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.

Seven months after buying BMM Testlabs, the New York investment firm Visualize has completed its purchase of eCOGRA, creating a testing and certification group it says holds licences or accreditations in more than 800 jurisdictions. The price of neither deal has been disclosed.

The two-year programme lets Kalshi match deposits and trading with bonus credits, target them by account age, inactivity and location, and confine them to sports contracts. It went to the CFTC as the exchange certified contracts on Premier League sanctions against Manchester City, days after reports of a verdict against the club.

A unanimous panel has held that Kalshi's sports contracts are not swaps, and that federal commodities law would not shield them from state gambling law even if they were. It is the second federal appeals court in a month to side with the states, leaving Kalshi with one win in three circuits as the Supreme Court weighs whether to take the question.

The Apollo-owned slot, systems and fintech supplier has replaced what its chief executive calls a "stuffy" corporate identity with one built around a "casino as a service" pitch. It arrives in the same fortnight as a new finance chief hired to sharpen cash flow.

Attorney General James Uthmeier has told five of the largest advertising platforms that promoting sweepstakes casinos to Floridians is a crime, and wants written proof they have stopped. After the operators and their payment processors, Florida has reached the marketing layer.

The National Council on Problem Gambling has given no reason for Maurer's departure, which follows its director of programs out of the door and four state bodies out of its membership since it took $2 million from Kalshi in May. The board has started its second executive search in 20 months.

Research commissioned by the American Gaming Association says gamblers score higher on financial literacy than non-gamblers, and that prediction-market users are nearly as confident as sports bettors but test like non-gamblers. The trade body is using it against the exchanges.

Kalshi's clearing house wants approval to let a few large traders post less than full collateral on some contracts. Sports, culture and mention markets are excluded, and the CFTC's review runs until early November.

The Supreme Court's stay runs out on 13 October and state police will start seizing machines the next day. Three rival bills, a proposed six-month delay and no agreed tax rate are waiting for lawmakers when they return on Monday.

The Massachusetts Gaming Commission has told its staff to question DraftKings over the New York Times investigation and to survey how every licensed sportsbook uses AI and machine learning. It has not found wrongdoing, and any rule-making would come later.

New York's attorney general has filed a second state-court case against a prediction market, this time against Polymarket's US exchange, alleging an unlicensed gambling business open to 18-year-olds. The relief sought mirrors the Kalshi suit that drew the federal regulator into the fight in August.

Pennsylvania's gaming regulator approved two consent agreements over paperwork failures, one against a casino group that was the subject of a takeover bid until yesterday. It also added ten people to its exclusion lists, including a gambler who left a five-year-old alone in a casino garage.

A legislative audit says the Montana Lottery, the Department of Administration and the governor's office would not let auditors review emails about how the lottery handled its biggest vendor. When the contract was finally put out to tender, the incumbent's rate fell from 8% to 5.05%.

A Republican senator who co-sponsored a bill to classify sports event contracts as gambling wants the Senate Judiciary Committee to question Donald Trump Jr. and Hunter Biden about trading on their fathers' office. Trump Jr.'s ties to Kalshi and Polymarket are one line in the case, and the committee's chairman is in no hurry.

Seven horseplayers say computer-assisted wagering has turned American pari-mutuel pools into an illegal gambling operation. The tracks and tote companies say the bettors cannot point to a single wager the syndicates affected, and a hearing is reported for 9 October.

North Carolina's regulator has fined two operators over self-reported failures: Underdog let 38 under-21s open sportsbook accounts, and bet365 sent a push notification to people on the state's self-exclusion list. Underdog left the market in December, which makes its fine a bill for a business that no longer operates there.
