Barclays Center, current home of the Nets and future home of the Islanders, is up for sale, Sports Business Daily reported Monday.
The report said the investment bank Evercore Partners is expected by next week to begin selling Forest City Enterprises' 55-percent stake in the arena.
SBD cited investment banking sources' estimates of a top valuation for the building of $750 million.
Barclays Center was named Sports Facility of the Year for 2013 at the Sports Business Awards and based on ticket sales for concerts in the first six months of 2014 is the most popular arena in the country, SBD reported.
Forest City, which is controlled by the Nets' former majority owner, Bruce Ratner, also owns 20 percent of the Nets themselves, and Evercore also has been shopping that on the market, so far unsuccessfully, in part because of the Nets' heavy financial losses.
Ratner was the force behind the construction of Barclays in the first place, a long, expensive battle that finally resulted in its opening two years ago.
