Elon Musk’s rocket company SpaceX is now worth nearly $150 billion following a share sale by existing investors, according to CNBC. SpaceX shares are now valued at $81 a piece, one shareholder told The Information. Shares are up 5% from $77, where they were valued earlier this year ahead of the secondary sales, the person said. Secondary sales are when existing investors sell their shares to new or current investors, without raising new capital for the company. SpaceX, the most valuable private company in the U.S., organizes secondary share sales around twice a year to give liquidity to existing investors and employees. The company plans to sell $750 million in secondary shares at the $81 per share price, according to CNBC.
