About Entain

Welcome to Entain. Our journey as Entain began when we evolved from GVC Holdings on 9th December 2020, but our brands have been paving the way and making history since the 1880s. Today, we’re one of the world’s largest sports betting and gaming entertainment groups – a FTSE 100 company that is home to more than 25 widely recognised brands, such as bwin, Coral, Foxy, Gala, Ladbrokes and partypoker. But that’s just the beginning. We’re constantly broadening our horizons and expanding our global influence. For example, our partnership with MGM Resorts International has allowed us to make waves in the US by powering BetMGM with our bespoke and top-of-the-line technology. It’s with this unique technology that we’re revolutionising our industry, and we’re boldly working towards being THE world leader in sports betting and gaming. Really though, it’s the people that truly make us who we are. There’s over 30,000 of us around the world and counting, but we all play for the same team. We’re proud to promote a culture that shatters barriers to unite, and encourages uncompromised diversity of background, thought and experience. When we win, we win together. If you share our values and want to be part of the revolution, we want you on our team.
