SpaceX Goes Public at $1.8 Trillion — the Largest IPO in History — Raising Governance and Valuation Concerns
SpaceX is debuting on US public markets at a $1.8 trillion valuation, surpassing Saudi Aramco's 2019 record. The IPO's scale, a Nasdaq rule change fast-tracking index inclusion, Elon Musk's near-unchecked voting control, and analyst warnings of overvaluation are raising serious concerns for pension funds and ordinary retirement savers.
What happened
SpaceX is listing on US public markets at approximately $135 per share, implying a $1.8 trillion valuation — the largest IPO in history. The company is oversubscribed by up to four times its planned offering, with roughly $70 billion in orders. However, Morningstar analysts value SpaceX at just $63 per share, a 53% discount to the IPO price. Nasdaq changed its rules earlier in May to allow mega-cap companies like SpaceX to enter its index after just 15 trading days, bypassing the traditional seasoning period designed to let a stock prove its value. The S&P 500 did not change its rules. SpaceX also posted a $4.9 billion net loss in its most recent fiscal year, despite $18 billion in revenue. OpenAI and Anthropic have both confidentially filed for their own IPOs, each targeting roughly $1 trillion valuations.
Why it matters
Because index funds are contractually obligated to hold stocks in proportion to their weight in an index, passive investors — including millions of people with pension plans, 401(k)s, and university endowments — may have no choice but to gain exposure to SpaceX at its IPO price, regardless of whether they consider it fairly valued. The abbreviated 15-day Nasdaq inclusion window leaves little time to assess how the stock actually trades. Compounding this, SpaceX's governance structure grants Musk up to 85% of voting power despite owning 42% of equity, effectively making him impossible to remove without his own consent — a structure that major pension funds in New York and California have publicly criticized. If the valuation fails to hold, losses would ripple through pension funds serving teachers, firefighters, police officers, and university endowments.
What could happen next
OpenAI and Anthropic are expected to follow SpaceX to public markets soon, each targeting valuations around $1 trillion. The Nasdaq rule change that benefits SpaceX would apply to these listings as well, meaning similar dynamics — fast index inclusion and limited seasoning — could affect passive investors again in short succession.
Context
In a normal IPO, companies must demonstrate sustained profitability before joining major indices like the S&P 500 or Nasdaq-100. This 'seasoning period' protects passive investors by ensuring a new stock has been tested by the market. SpaceX lobbied successfully for a Nasdaq rule waiver, compressing this window to 15 trading days. Index fund managers cannot simply opt out of holding a stock once it enters the index — they are contractually bound to track the index composition.
