S&P 500 ETFs can limit SpaceX IPO risk

SpaceX intends to list on Nasdaq under the ticker SPCX, offering 555.6 million Class A shares at $135 each. The sale would raise about $75 billion and imply a $1.77 trillion market valuation.

If SpaceX meets the index inclusion rules, the company could be added to the S&P 500. Inclusion would require index-tracking funds and ETFs to buy the stock over time, creating mechanically driven demand as funds adjust their holdings.

SpaceX reported $18.7 billion in revenue over the past year and a GAAP net loss of $4.9 billion for 2025. The company posted a $4.3 billion net loss in the first quarter, with much of that tied to costs from a newly integrated AI business and roughly $3 billion in capital spending on the Starship rocket program.

At the implied $1.77 trillion valuation, SPCX would trade at about 95 times trailing revenue. One estimate places a fair value near $780 billion, less than half the implied IPO price. Companies that begin trading at very high revenue multiples have in many cases seen sharp valuation declines in the months after listing.

Buying a broad S&P 500 ETF such as the Vanguard S&P 500 ETF (VOO) would give investors indirect exposure to SpaceX’s commercial satellite services, launch business and AI infrastructure while distributing position risk across 500 large-cap U.S. companies. Passive ownership through an ETF reduces the single-stock operational risk tied to heavy capital expenditures, large quarterly losses and the integration of new business lines, because swings in one stock are offset by the performance of others in the fund.

More than $30 trillion in assets are benchmarked to major U.S. and global indexes. A formal inclusion of SPCX in the S&P 500 at the implied valuation would make the company one of the largest U.S. firms by market capitalization and would reshape index weightings, affecting flows into many ETFs and mutual funds that track the index.

Market participants warn that buying SPCX at the IPO price carries risks related to the stretched revenue multiple and recent net losses. Passive index funds are presented as a way to gain exposure to SpaceX’s potential growth without taking on the full single-stock risk that comes with buying shares at the open.
