London-listed gaming operator William Hill has partnered with Monumental Sports & Entertainment, owner of the Capital One Arena in Washington DC, to create the first ever sportsbook inside a US professional sports arena.

The partnership, which is subject to regulatory approvals, will see the development of a William Hill Sports Book at the Capital One Arena, which will serve as the exclusive sports betting partner of the Washington Wizards, Washington Capitals, Washington Mystics and Monumental Sports & Entertainment.

“Monumental is dedicated to bringing the latest technology and innovation into our arena and delivering extraordinary experiences to our fans,” said Monumental Sports & Entertainment chairman and CEO Ted Leonsis. “We are excited to partner with William Hill, the industry leader in sports betting, to become the first professional sports arena in the U.S. to feature a sportsbook.

“Through this partnership, we are thrilled to enhance the fan experience with innovative gaming opportunities and transformational dining and culinary options not just on event days, but year-round. Our partnership with William Hill compliments our vision of making our arena the premier sports and entertainment destination in Washington, D.C.”

William Hill US chief executive Joe Asher said: “This sports book will be a flagship venue for the industry and will serve the sports fans of the Washington D.C. area unlike any other. Partnering with Ted Leonsis and the entire Monumental team was ideal. They share our vision and principles for bringing innovative sports betting opportunities to fans in a responsible way. This deal sets a new benchmark for how the industry will serve fans and how fans engage in sports.”

The sportsbook will be open daily, year-round during game days and certain in-arena events, where both ticketed and non-ticketed customers will have access. The sports book also will be open on non-event days and customers will have the option to wager on a William Hill mobile app inside the arena, as permitted by Washington D.C. regulations.
