WynnBet has become the latest victim of the consolidating U.S. sports betting market, as the online sportsbook will cease operations in eight states.

Nevada-based casino and hotel owner Wynn Resorts announced the reduction Friday to end WynBet’s operations “as soon as possible” in Arizona, Colorado, Indiana, Louisiana, New Jersey, Tennessee, Virginia, and West Virginia. WynnBet will continue to operate in Nevada and Massachusetts while its New York and Michigan standing is under review.

The company said its decision was driven by demands for marketing spend to acquire sports betting customers. WynnBet’s downsizing comes as ESPN is entering a $2 billion partnership with PENN Entertainment to launch ESPN Bet as another sportsbook option.
