- The company is seeking an estimated valuation of $1.8 trillion.

SpaceX is set to debut on the public market on June 12, aiming for a valuation of approximately $1.8 trillion. The highly anticipated initial public offering (IPO) has prompted index providers, including the Nasdaq 100 and Russell 1000, to adjust their inclusion rules, allowing for faster integration of mega-cap companies into their indices.
This shift means that millions of retirement savers who utilize broad index funds may soon hold SpaceX shares by default. While proponents argue that this reflects the evolution of market diversification, critics are concerned that the rule changes allow unprofitable, high-valuation firms to enter retirement portfolios prematurely. Morningstar has initiated coverage with a fair-value estimate of $780 billion—significantly lower than the company’s target—highlighting the skepticism surrounding the IPO’s pricing.
The S&P 500, however, has opted against relaxing its requirements, which mandate that companies must have a 12-month trading history and four consecutive quarters of profitability to be eligible for inclusion. Financial analysts, including those from Vanguard, suggest that while the inclusion of such large IPOs is notable, the actual impact on diversified retirement accounts remains limited due to the small percentage of total market weight these companies initially represent.
