WASHINGTON – (June 10th, 2021) – BetMGM announced today the expansion of its market-leading sports betting app into Washington, D.C. in partnership with the Washington Nationals, making BetMGM the only mobile sports betting app available at Nationals Park. Today’s news is part of BetMGM’s multi-year, exclusive partnership with the Washington Nationals, which also includes a retail BetMGM Sportsbook connected to Nationals Park, scheduled to open later this year.

“Launching in Washington, D.C. at Nationals Park sets the stage for our plans to expand BetMGM within the region, as we’ve already seen great success in Virginia,” said Adam Greenblatt, CEO of BetMGM. “The Washington Nationals have been a fantastic partner, committed to innovating the in-stadium fan experience and we’re looking forward to opening our retail sportsbook at the stadium later this year.”

The BetMGM app is now available for download on both iOS and Android in Washington, D.C. While the app can be accessed throughout the District, due to local restrictions, to successfully place mobile wagers, users will need to be within a two-block radius of Nationals Park**.** BetMGM’s gaming platform will provide Nationals fans a unique opportunity to enhance their game day experience and bring them closer to the action on the field.

“As our official sports betting partner, BetMGM further enhances the greatest in-venue fan experience in Washington, D.C. through its state-of-the-art entertainment products and services,” said Alan Gottlieb, Chief Operating Office of Lerner Sports Group. “The BetMGM mobile app will enable our fans to engage with the game in new and exciting ways, while the BetMGM sportsbook connected to Nationals Park will provide Nationals fans and the D.C. community with a first-class gathering place to celebrate their passion for sports.”

BetMGM's integration with MGM Resorts' M life Rewards program allows Nationals fans the opportunity to redeem their gameplay for world-class experiences at MGM Resorts properties nationwide, including Borgata in New Jersey, Bellagio and MGM Grand in Las Vegas, and MGM National Harbor in Maryland, just across the river.

Jorge Perez, President & COO, MGM National Harbor, said, “As a leader in delivering monumental experiences, today is a very exciting day for MGM National Harbor. This becomes the first of many offerings we are developing to seamlessly connect sports and entertainment across the DMV, providing fans with unique opportunities to interact with our world-class resort and casino.”

As BetMGM continues to expand its sports betting platforms, responsible gaming education remains a key focus. BetMGM is proud to provide resources to help customers play responsibly. For more information on BetMGM follow @BetMGM on Twitter.
