SpaceX's stock (NASDAQ: SPCX) gained 15.8% on Friday. The rise occurred as a significant post-IPO lock-up expiration, which made 911.5 million shares eligible for trade, did not lead to a sell-off, which the market interpreted as an endorsement from insiders. Additionally, SpaceX, alongside Tesla, announced a $16.8 billion investment in Terafab, with the first phase involving a 100-million-square-foot semiconductor complex in Texas, expected to create at least 3,000 jobs.
