WSOP Online, which is powered by 888’s proprietary next-generation poker platform, will run bracelet events and weekly tournaments for players in Michigan.
The WSOP brand launched in 1970 and has awarded approximately $3.5bn (£2.7bn/€3.2bn) in total prize money.
888’s entrance into the legal Michigan market means its online gambling products are now available across six US states.
“We are delighted to support WSOP with its eagerly anticipated launch in Michigan, bringing the world’s most renowned poker brand to players in the Great Lake State,” 888’s US business development director John Atkinson said.
“This is not only another important milestone for WSOP but a key moment for 888, providing an opportunity to introduce our newest poker platform to more players across North America while strengthening our relationship with our long-term partner Caesars Interactive Entertainment.”
The launch comes after 888 this week reported an 18% year-on-year drop in revenue for the first quarter of its 2022 financial year, which it expects to be the final full quarter before it acquires William Hill’s non-US assets.
Revenue for the three months through to 31 March amounted to $224m, down from $273m in the corresponding period last year, 888 said in a trading update.
