SpaceX IPO Raises Index Inclusion Concerns

SpaceX is scheduled to debut on U.S. public markets on Friday, June 13, 2026, in what is projected to be the largest initial public offering (IPO) in history, valued at nearly $1.8 trillion. This event has prompted concerns among institutional investors regarding potential overvaluation and the implications of a recent Nasdaq rule change for index inclusion.

The company's valuation of $135 per share significantly exceeds analyst estimates, such as Morningstar's valuation of $63 per share. Despite this, the IPO is oversubscribed by up to four times its planned offering, with approximately 20% of shares allocated to retail investors. A new Nasdaq rule, enacted in early May, could allow SpaceX to enter the Nasdaq-100 index after just 15 trading days, bypassing traditional seasoning periods that require companies to demonstrate sustained profitability. S&P Dow Jones Indices, which manages the S&P 500, has not altered its rules.

This accelerated index inclusion could compel index funds, including pension funds, to acquire SpaceX shares regardless of valuation concerns, as they are contractually obligated to track index components. For example, North Carolina's state treasurer indicated that while the state's pension fund would not directly purchase SpaceX shares due to cost, it would participate through broader index funds. Additionally, the proposed governance structure for SpaceX, which grants CEO Elon Musk approximately 85% of voting power despite 42% equity ownership, has raised concerns among state-level fund managers regarding board accountability and shareholder influence.
