Fortune has learned some early Uber shareholders did sell stock back to the company earlier this year, including at least one at around the aforementioned $135 per share price (which works out to a valuation just south of $4 billion).
Many believe that the company will go public at some point this year, continuing the recent IPO boom. An upcoming IPO for Uber would also be massive, as the company is currently valued at an amazing $41 billion after landing $1 billion in financing at the beginning of last December.
