Would be a good plot for a movie: an AI that's built a company by itself through stolen identity, anonymous companies and trusts, and impersonating a human on video calls etc. "Has anyone ever actually seen him in person?" Starts acquiring other companies and some auditor protagonist eventually discovers it and that it's controlling a third of the economy or something.
