Amazon founder Jeff Bezos encouraged his siblings Mark and Christina to invest $10,000 each in the company in the mid-1990s. Little did any of them know at the time that this would make them billionaires one day. In 1996, Bezos’ siblings each bought 30,000 shares of Amazon for $10,000. Jeff had one condition, though: if Amazon failed and the investment turned sour, he still wanted to be invited to his siblings’ homes for Thanksgiving, according to the book “The Everything Store: Jeff Bezos and the Age of Amazon.” Luckily for Bezos and his siblings, Amazon flourished and turned them all into billionaires. That small $10,000 investment back in 1996 is now worth $1.30 billion, assuming that neither of the Bezos siblings sold any shares so far. This makes for a staggering gain of 13,025,889%. . #jeffbezos
