In a significant turn of events, SpaceX has seen its valuation skyrocket to an astonishing $2.1 trillion following a remarkable 19.2% increase in its stock price upon debuting on Wall Street. This valuation places SpaceX above industry giants like Exxon Mobil, Bank of America, and Coca-Cola combined, highlighting the market’s exuberance around the company’s potential, irrespective of differing opinions on its growth strategies or the stature of its CEO, Elon Musk.
The potential inclusion of SpaceX in high-profile stock indexes could have far-reaching implications for investors, particularly those relying on 401(k) accounts. As more individuals gravitate toward index funds—investment vehicles that replicate market performance—there is an increasing dependency on how these indexes are constituted. With index funds generally offering lower fees and better long-term performance compared to actively managed funds, the growing popularity is reshaping investment strategies across the spectrum.
Recent data illustrates a trend: only about 21% of actively managed U.S. stock funds have managed to outperform their average index counterparts over the past decade, according to Morningstar. This growing disparity has led to more capital being funneled into U.S. index funds, eclipsing actively managed funds since early 2024.
Indexes serve as essential benchmarks for understanding market trends amidst the vast array of competing stocks. The S&P 500, which tracks 500 of the largest U.S. companies, is arguably the most renowned index, guiding trillions of dollars in investments, either directly or as a benchmark. Conversely, the Dow Jones Industrial Average, despite its long history, includes only 30 major companies and is often overshadowed by the broader market influences reflected in the S&P.
The push for companies to be included in these indexes stems from the substantial impact index funds have on stock prices. Announcements of a company’s inclusion in an index can lead to significant price surges. There are more than 1,000 index funds available, with 185 tracking the S&P 500 alone, making competition fierce for index inclusion.
With the Nasdaq altering its rules, certain large companies can now gain entry to the Nasdaq 100 index after merely 15 trading days, a notable departure from past practices. This facilitates quicker access to capital influx through index fund investments. Recently, Invesco’s QQQ exchange-traded fund, which tracks the Nasdaq 100, boasts nearly $477 billion in total investments, indicating that soon, holders of this fund may find themselves owning shares of SpaceX with minimal effort.
Furthermore, notable AI enterprises like Anthropic and OpenAI are gearing up for their own IPOs, potentially elevating their market valuations to nearly $1 trillion. The rapid ascension of these companies, supported by private investments, has prompted a reevaluation within the investment community regarding the speed at which companies are inducted into major indexes.
However, not all entities agree on accelerating the inclusion process for large IPOs. The S&P 500 Index, for instance, remains committed to its established criteria, requiring a stock to have traded on an eligible exchange for at least a year. Additionally, companies need to demonstrate profitability in the most recent and surrounding quarters. Despite the massive valuation, SpaceX recorded a loss of $4.9 billion last year and another $4.3 billion in the first quarter of 2026, raising questions about its long-term profitability and subsequent eligibility.
Concerns regarding corporate governance have also surfaced, with pension fund officials from California and New York expressing apprehensions about the substantial control Elon Musk retains through a specially structured class of stock. They highlighted that such governance could effectively render Musk nearly untouchable in his role as CEO.
Investors in index funds may find themselves inadvertently associated with companies they feel uncomfortable supporting. Despite criticisms of valuations, companies like Tesla have remained within the S&P 500, even amid allegations of overvaluation. While some indexes have adopted exclusionary criteria based on corporate governance standards, investors are urged to remain vigilant in selecting funds aligned with their values, as evident from Tesla’s removal from the S&P 500 ESG Index in 2022.
