What is Cluster Tumble?
On Friday, a Department of Justice attorney told a federal judge that the Scotts Valley Band of Pomo Indians knew the Interior Department could reverse an earlier determination that its Vallejo land was eligible for gaming.
Despite those warnings, the tribe opened its “Preview Casino” on July 24, offering Class II gaming out of modular structures.
Six days later, Interior determined that the land did not qualify for gaming under the Indian Gaming Regulatory Act (IGRA), forcing the tribe to shutter the operation and take the federal government back to court.

The 2026 NFL season arguably marks the most contentious battle to attract customers interested in sports betting and predictions, dating back to the historic PASPA decision. For the first full NFL season, traditional sportsbooks such as DraftKings will offer sports-event contracts in the three most populous US states – California, Texas and Florida.
Unlike regulated sportsbooks, prediction markets allow customers between the ages of 18 and 21 to trade on sports-event contracts. Craig Carton, a sports talk host with WFAN 660 AM in New York, criticised the athletes for their endorsement of Polymarket. Carton, a recovering compulsive gambler, opined that the “unregulated” gambling markets are driving Americans into bankruptcy and kids out of school. Regulated books prohibit those under 21 from betting on their platform, leading Carton to question the celebrities for promoting the company.
“At what point does someone come along where you say no to the offer?” Carton asked.

Yet Dan Waugh, partner at Regulus Partners, pushes back against the idea that enforcement notices reveal a fundamentally non-compliant sector.
“Operators failing compliance checks is never a good look,” he says. Campaigners often claim that financial sanctions are priced in and that the Commission should revoke more licences, although Waugh does not believe operators view settlements merely as a cost of doing business.
Nor are regulatory breaches unique to gambling. Waugh notes that Tesco was fined more than £8 million for food hygiene failings in 2021, without parliamentarians demanding that it should be prevented from selling cornflakes.
