Palantir Industries, the data-mining company owned by billionaire Peter Thiel, went public this week. But take note, if you buy stock in the company you will have virtually no say in the company's operations. Thanks to super-voting shares, Thiel and two other co-founders will retain voting control in perpetuity. Other Silicon Valley companies like Alphabet, Facebook, and Snap have similar voting structures. As Ohio State professor Michael Weisbach notes, "They set it up so Peter Thiel can still sort of run it like a private company and still have the advantage of being public." The three co-founders will retain 49.99 percent of the voting power in the company regardless of the number of shares owned.
