Bill Ackman is up next, with his hedge fund gains, his holding company, and his newest SPAC PSTH. While Bill Ackman has had some impressive celebrity wives, he also has had a lot of beef with other businessmen, including Carl Ichan and Herbalife, which Ackman took a hefty short position against, betting $1 Billion that it would crash to zero.  

Pershing Square Tontine Holdings is Ackman's Special Purpose Acquisition Company (SPAC) that was set to take on Universal Music Group, however,  up against SEC interference, the future of the SPAC is uncertain.
