SpaceX could enter millions of investor portfolios quickly after its Nasdaq debut opened fast-entry paths into major indexes. Funds tracking those indexes could add exposure within weeks of the listing, widening passive investor access after the largest IPO on record.
SpaceX began trading at $135 per share after raising more than $85 billion, making it the largest IPO on record. Its valuation later surpassed $2 trillion, placing the company among the most valuable publicly listed businesses in global markets.
A company of that size can qualify for major benchmarks quickly, but passive investors will not all receive exposure at the same time. The timing depends on the index behind each fund, including Nasdaq-100 products, MSCI global trackers, FTSE Russell funds, and CRSP-based portfolios, whose indexes underpin many Vanguard U.S. index funds, alongside S&P 500 trackers.
“The first practically important question for investors using index or passive strategies in their portfolios is not whether SpaceX is a good investment – it is will you hold it, where and when?”
Nasdaq has already created a faster route for large IPOs. The exchange’s May 1, 2026, methodology update allows newly listed companies ranked among the top 40 by market capitalization to enter the Nasdaq-100 within 15 trading days. Flintoft stated, “while SpaceX’s shares listed on the Nasdaq stock exchange, they will take slightly longer to join the Nasdaq-100 index.”
Those rules explain why SpaceX could appear quickly in several fund families. Nasdaq-100 trackers can use Nasdaq’s 15-trading-day window, FTSE Russell products can use the fifth-trading-day process, and MSCI-linked funds can apply MSCI’s large-IPO framework.
S&P 500 Funds Remain on a Different TimelineFTSE Russell has also moved toward faster IPO inclusion. On May 26, 2026, the index provider said eligible large IPOs can enter Russell U.S. indexes after the fifth trading day, using first-day free float, following a February market consultation.
MSCI provides another route into global index funds. Its Global Investable Market Indexes have used fast-track rules for large IPOs since 2007, covering benchmarks tied to MSCI World, MSCI ACWI, MSCI Emerging Markets, and MSCI EAFE products.
Flintoft explained:
“If your portfolios include Nasdaq-100 trackers, FTSE Russell-based products, MSCI World or MSCI All Country funds, those products will acquire exposure within weeks of listing.”
“The initial weighting will be measured in basis points given the constrained free float, but as lockup tranches release over the following six months, the weighting will grow – depending on how the share price performs,” he further shared.
S&P 500 funds remain on a different timeline. Flintoft noted that S&P Dow Jones Indices confirmed June 4 that companies must trade publicly for at least 12 months and be profitable under U.S. Generally Accepted Accounting Principles, the accounting standards used in corporate financial reporting. SpaceX has yet to meet either requirement, placing potential S&P 500 inclusion no earlier than mid-2027.
The company reported a $4.94 billion net loss in 2025, compared with a $791 million profit in 2024, while revenue rose 33% to $18.67 billion. It also recorded a $4.3 billion loss in the first quarter of 2026.
The first portfolio changes should be small, with Flintoft citing Bloomberg data showing about 8% of SpaceX shares are currently tradeable. As additional shares are released after the first quarterly earnings report and at later lockup dates, index weightings could increase over time. SpaceX could appear in Nasdaq-100, FTSE Russell, MSCI, and CRSP-linked products over the coming weeks as those indexes follow their respective inclusion schedules, while S&P 500 trackers remain subject to existing eligibility rules.
