Two of the eight mobile sports betting platforms operating in Massachusetts are planning to stop taking bets here, shrinking a market that has been largely dominated by two companies since it launched in the state less than a year ago.

WynnBet confirmed Wednesday that it plans to cease online wagering in Massachusetts and Betr announced last week that it would not renew its temporary license to take bets in Massachusetts.

Both departures will go before the Mass. Gaming Commission during a meeting Thursday.

The end date of WynnBet operations in Massachusetts depends on the commission’s approval and that the app’s shutdown will not affect the WynnBet Sportsbook at Encore Boston Harbor in Everett, the company said.
