Major sportsbook DraftKings has outgrown its current digs in Boston. It has had to relocate its headquarters to a larger building, but asserts that it is committed to maintaining the city as its home. The new location will be unveiled on Tuesday (March 26) in a ribbon-cutting ceremony and a tour of the new spaces.

DraftKings first announced that it needed new facilities early last year. Its new space is almost twice as large as its previous headquarters and comprises a total of 105,000 square feet new Copley Square in the Back Bay neighborhood of Boston. Its previous headquarters was located close to South Station.

DraftKings first launched operations in 2012 and quickly ramped up its activities in the daily fantasy sports (DFS) market to become one of Boston’s largest tech companies. It has continued to expand over the years and, after the U.S. Supreme Court axed the Professional and Amateur Sports Protection Act of 1992 (PASPA) last May, has seen a number of new deals, including new operations in New Jersey and Mississippi.

Early last year, the company employed about 425 employees. It has plans to expand the workforce to over 700, of which 600 will be based in Boston.
