Costa Rica-based sportsbook 5Dimes will block access for US customers, hinting that it may look to secure licenses to move into the US regulated betting market.
The operator, which does not yet hold any US licences but is popular among American bettors, will stop taking bets from US IP addresses from September 21.
Players must make final withdrawal requests by September 25, and funds that cannot be delivered to players by September 30 will be deemed abandoned.
In a message to customers, the operator did not explicitly say it would enter the regulated market, but said the growth of legal betting prevented an opportunity to offer a new service to customers.
“5Dimes is excited to announce that it is embarking on a new business venture,” the operator said. “With the evolving legal landscape in the United States, we want to take advantage of the opportunity to offer an improved online sports betting experience to our many US customers.
“In order to do this, we need to suspend temporarily our service of the US market so that we can launch our new operations with a fresh start,” it explained.
“We wish we could tell you everything about our future plans, but for now, please stay tuned and know we will soon reward your loyalty with extraordinary gaming experiences.”
Other sites from the 5Dimes Group, such as BetAnySports, have not yet shown any indication of shuttering the US market.
