Irish fantasy sports and gambling conglomerate Flutter Entertainment will open new digs for one of its subsidiaries in the Flatiron District.

Flutter signed a 12-year lease for 35,898 square feet across the entire 23rd floor of the recently built One Madison Avenue office building, landlord SL Green Realty announced. Asking rent was $170 per square foot, according to a spokesperson for the developer.

Flutter is the parent company of U.S. sports betting company FanDuel, and its overseas brands include Paddy Power, Betfair and Sportsbet. Flutter made its debut on the New York Stock Exchange in January.

The SL Green spokesperson did not disclose which one of Flutter’s mobile sports brands will move into the 1.4 million-square-foot building.
