SpaceX IPO: How Index Funds Will Sneak Into Every Portfolio Within Weeks

SpaceX Could Enter Major Index Funds Within Weeks After Trillion-Dollar IPO

SpaceX’s recent stock market launch makes it possible for many more investors to own shares quickly. Because SpaceX is now listed on Nasdaq, funds that follow major stock indexes could begin including it in their portfolios within weeks, giving a wider range of people the opportunity to invest after what was already a very large initial public offering.

  • Key Takeaways:
  • SpaceX could join major indexes within weeks of its Nasdaq debut.
  • Only about 8% of SpaceX shares are currently tradeable, limiting initial index weightings.
  • Broader index exposure could build well before SpaceX becomes eligible for the S&P 500.

Fast-Entry Rules Could Put SpaceX Into Millions of Investor Portfolios

Millions of investors may soon find SpaceX (Nasdaq: SPCX) inside funds they already own, according to James Flintoft, head of investment solutions at AJ Bell. The company’s Nasdaq debut has opened fast-entry routes into several major indexes, while S&P 500 funds remain tied to a longer eligibility schedule.

SpaceX started trading on the stock market at $135 a share, following a fundraising effort that brought in over $85 billion. This made it the biggest initial public offering ever. Soon after, the company’s value went above $2 trillion, making it one of the most valuable companies traded publicly around the world.

Companies that grow rapidly can soon be included in major market indexes, but it won’t happen for all investors simultaneously. When exposure occurs depends on the specific index each fund follows – whether it’s the Nasdaq-100, MSCI global indexes, FTSE Russell funds, or CRSP indexes (which are the foundation for many Vanguard U.S. funds), as well as S&P 500 trackers.

AJ Bell, a U.K. investment platform offering individual savings accounts (ISAs), pensions, and dealing accounts, said the listing raises important questions for passive investors. Flintoft said:

For investors using index funds or passive investment strategies, the key question isn’t whether SpaceX is a worthwhile investment, but rather if, where, and when they will actually own it.

Nasdaq has streamlined the process for large companies going public. A change taking effect May 1, 2026, allows new listings that rank among the top 40 in market value to be added to the Nasdaq-100 index within just 15 trading days. According to Flintoft, even if a company like SpaceX is listed on Nasdaq, it will still take a little longer to qualify for inclusion in the Nasdaq-100.

These rules clarify how SpaceX became included in various investment funds so quickly. Funds tracking the Nasdaq-100 have a 15-day window for making changes, FTSE Russell funds use a five-day process, and those linked to MSCI can utilize MSCI’s guidelines for large initial public offerings (IPOs).

S&P 500 Funds Remain on a Different Timeline

FTSE Russell is now allowing some new company listings to be included in its U.S. indexes more quickly. Starting May 26, 2026, qualifying large initial public offerings (IPOs) can be added after just five days of trading, using the number of shares initially available. This change follows feedback gathered from the market in February.

MSCI offers another way to invest in global index funds. Since 2007, they’ve had a process for quickly adding large new companies (IPOs) to their key indexes – those that track the world’s developed and emerging markets like MSCI World, ACWI, EAFE, and Emerging Markets.

Flintoft explained:

If you invest in funds that follow the Nasdaq-100, FTSE Russell, MSCI World, or MSCI All Country indexes, those funds will start including the new listings very soon – usually within a few weeks.

As an analyst, I understand the stock’s initial inclusion in relevant indices will be calculated using basis points due to its limited number of shares readily available for trading. However, as shares held under lock-up agreements become eligible for sale over the next six months, the weighting is expected to increase – assuming the share price performs well.

Funds that track the S&P 500 are operating on a separate schedule. According to Flintoft, S&P Dow Jones Indices stated on June 4th that companies need to be publicly traded for at least a year and demonstrate profitability according to standard U.S. accounting rules. Because SpaceX hasn’t met these criteria yet, it likely won’t be added to the S&P 500 until mid-2027 at the earliest.

In 2025, the company experienced a net loss of $4.94 billion, a significant drop from the $791 million profit it earned in 2024. Despite this, revenue increased by 33% to $18.67 billion. The challenging financial performance continued into 2026, with a further loss of $4.3 billion reported for the first quarter.

Initial adjustments to investment portfolios involving SpaceX should be modest, as only about 8% of its shares are currently available for trading according to Bloomberg data. As more shares become tradeable after the first earnings report and subsequent lockup periods end, SpaceX’s importance within these indexes could grow. Over the next few weeks, expect to see SpaceX included in various indexes like those from Nasdaq-100, FTSE Russell, MSCI, and CRSP as they follow their regular procedures. However, inclusion in S&P 500 trackers will depend on whether SpaceX meets their specific requirements.
