SpaceX’s IPO Could Jeopardize Your Retirement Account

Fast entry rules in the stock market are changing the game for companies like Elon Musk’s SpaceX. The Nasdaq and the FTSE Russell have recently adopted fast entry rules that will allow SpaceX to be added to their benchmarks just days after the company’s initial public offering (IPO) on Friday. This means that millions of Americans who own index funds in their retirement accounts will soon be forced to own shares of SpaceX, a popular yet unprofitable company.

Trading under the ticker symbol SPCX, SpaceX’s IPO debut is expected to come with a massive $1.75 trillion valuation, making it the largest IPO in history. The company’s unprecedented decision to offer 30% of its IPO shares to retail investors has caught the attention of index providers like the Nasdaq and the FTSE Russell. In response, both indices have adjusted their rules to allow for faster inclusion of newly listed companies.

Historically, stock market indices have set strict rules around how long a company must exist and how well it must perform before being added to a benchmark. For instance, the Russell 1000 previously required companies to wait for quarterly or semi-annual reviews before being included. However, with a flood of high-profile IPOs expected this year, the Russell 1000 has slashed its inclusion rule for companies with large market caps to just five trading days.

The Nasdaq-100, an index of the 100 largest non-financial companies listed on the Nasdaq stock exchange, has also adjusted its rules to allow qualifying companies to join its ranks after 15 trading days. These changes were partly motivated by SpaceX’s decision to offer a significant portion of its IPO shares to retail investors.

While the fast entry rules may benefit SpaceX by attracting more retail investors and raising more capital, they also pose risks for investors. Managers of funds mirroring the indices’ compositions will be forced to purchase SpaceX shares, even though the company is currently unprofitable. SpaceX generated $19 billion in revenue in 2025 but operated at a net loss of $5 billion, making it a risky investment for index funds.

Ultimately, the accelerated inclusion of SpaceX in stock market benchmarks highlights the evolving landscape of the market and the willingness of major indices to bend the rules for high-profile companies. Investors should carefully consider the risks and rewards of investing in companies like SpaceX, especially as they become increasingly integrated into popular index funds. Passive investors face a unique risk when investing in market cap-weighted indices, especially with the upcoming SpaceX IPO. With SpaceX’s target valuation, passive investors will automatically become significant shareholders of SpaceX, leading to concentration risk. This risk arises from overexposure to a single investment, which can result in outsized losses.

The Nasdaq has modified its weighting calculation to prevent companies like SpaceX from dominating its performance. However, this adjustment introduces a new issue – trading index stability for IPO volatility. Valuing an asset like SpaceX, with negative earnings and an uncertain revenue stream, is challenging, making price discovery difficult. As a result, the IPO is expected to have a volatile opening day.

For retirement savers, this volatility poses a sequence of returns risk, where poor market performance early in retirement can impact overall returns for years. Additionally, factors like insider selling post-IPO can exacerbate volatility beyond investors’ control. Despite these risks, there is significant demand for SpaceX shares from retail investors, thematic ETFs, and institutional buyers, indicating a strong IPO performance.

Some retirement plans, like Denmark’s AkademikerPension, have blacklisted SpaceX due to governance concerns. However, investment manager Shulman believes that SpaceX offers a better price floor, especially with the success of Starlink in the broadband market. For retirees, owning SpaceX stock or exposure through index funds could provide outsized gains before retirement drawdowns.

As retirement nears, it’s essential for savers to rebalance their portfolios to reduce risk exposure. While growth opportunities exist, caution and diversification are crucial in investment decisions. Investing in SpaceX may offer excitement and potential gains, but it’s important not to allocate all resources to a single investment. Overall, careful and deliberate investment strategies can help retirees navigate the opportunities and risks associated with the SpaceX IPO.
