Revolvero

What is Revolvero?

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.

A Bank of America study released on 1 September found that the median deposit account balance of households that participated in online betting was 59% higher than households that avoided the activity. As prediction markets rapidly expand alongside traditional sports betting, the findings have prompted “some to blur the lines between entertainment and investment”, according to a proprietary study undertaken by BofA.

Tim Miller, who resigned from the UK Gambling Commission earlier this year, has stepped down from the GREF board and has relinquished his role as treasurer. 

Miller served on the forum for several years and was a key UK figure during a period when the Gambling Commission implemented extensive reforms to online gambling regulation and affordability checks. GREF expressed its gratitude for Miller’s contributions during his tenure.

Jean-Michel Costes has also left the board after concluding his role at France’s Autorité Nationale des Jeux (ANJ).

Overall, it’s been a busy stretch for the board since the start of 2025. In that time the regulator has issued five multimillion-dollar anti-money laundering fines to entities on the Las Vegas Strip, an unprecedented run of sanctions for America’s gambling capital.

Four of the investigations – those involving Resorts World Las Vegas, MGM Resorts, Caesars Entertainment and the Venetian – centred around AML violations related to illegal bookmaker Mathew Bowyer, who was placed on the state’s exclusion list in April. The other case involving Wynn Las Vegas did not pertain to play from Bowyer.

Wynn forfeited $130 million to the federal government for a slew of proxy betting violations, which was “believed to be the largest forfeiture by a casino based on admissions of criminal wrongdoing”, per federal prosecutors.
