On Sunday, the eyes of the nation will fall on Atlanta’s brand-new Mercedes-Benz Stadium, site of the 53rd Superbowl. As players and spectators pour into the city, they’ll be dazzled by a state-of-the-art retractable roof and an enormous, wrap-around digital screen. What will be less apparent to thousands of spectators and millions of television viewers is a different kind of innovation—a carefully concealed legal clause that will privatize future profits of the publicly-funded stadium.
