- SpaceX shares priced at $135 Thursday, peaked at $176.28 intraday, then slid to close at $160.95 — a 19% first-day gain that valued the company at $2.1 trillion and made it the sixth-largest in the U.S.
- If added to the S&P 500 today, SpaceX would represent over 5% of the index by weight, a figure that would reshape any passive fund that tracks it
- SpaceX trades at 90 times its sales — not profits — a multiple portfolio manager Adam Johnson of Bullseye American Ingenuity Fund said indicates a valuation "divorced from underlying business fundamentals"
- Elon Musk must hold his shares for 366 days post-IPO, while other early investors can sell after 180 days and may unload up to 20% of their holdings following the next earnings report
- Elon Musk told Axios he had given SpaceX "less than a 10% chance of succeeding" before its debut, framing the bet as building a "space-faring civilization"
- University of Florida finance professor Jay Ritter's research shows the majority of companies that go public underperform the market in the first three years
- Laffer Tengler Investments' Nancy Tengler said the debut makes the possibility of Tesla merging into SpaceX "even more interesting and compelling"
Why it matters: A $2.1 trillion valuation on day one instantly makes SpaceX systemically important — a single stock that would command over 5% of the S&P 500 if added. But the 90x sales multiple, combined with a 180-day insider lockup that expires before the next earnings report, means the test of whether retail demand can absorb early-investor selling pressure starts now.
