Mark Cuban has pivoted from one venture to the next throughout his career, and his latest moves have left observers wondering: after selling a majority stake in his professional basketball team and announcing plans to exit his reality television job, what will the dotcom billionaire do next? 

Cuban said last week he would step down from his role on Shark Tank, a popular reality television programme in which he and other entrepreneurs assess start-up pitches. The next day, news emerged that he had reached an agreement to sell his majority stake in the Dallas Mavericks professional basketball franchise to the family of Sheldon Adelson, the late casino magnate and Republican donor — although he will retain control of the team’s basketball operations and own a minority stake.

Now, speculation is swirling about what Cuban, 65, plans to do next — and whether that new venture will continue his nearly three-decade record of savvy timing. In an email to the Financial Times, Cuban declined to address questions about his future plans until after the deal closes, which could happen as soon as this month.
