SpaceX is preparing for one of the most anticipated public market debuts in history.
Elon Musk’s aerospace and satellite company is expected to begin trading on the Nasdaq on June 12 with a valuation near $1.75 trillion. The offering could raise as much as $86 billion, potentially making it the largest IPO ever in the United States.
Most of the attention has focused on the company’s valuation and what the IPO could mean for early investors. But a subtle shift in the rules governing major stock indexes could make the listing consequential far beyond Wall Street.
Nasdaq rewrote its index rules weeks before SpaceX’s debut
The Nasdaq-100 tracks the 100 largest non-financial companies on Nasdaq and anchors a roughly $1.4 trillion ecosystem of assets, including approximately $700 billion in ETFs and mutual funds, and a similar amount in derivatives, according to Nasdaq.
On May 1, the index introduced a “fast entry” provision for companies that rank in the top 40 by market capitalization at the time of listing.
Under the new rule, qualifying companies can join the Nasdaq-100 after just 15 trading days, down from a previous waiting period of roughly three months, Reuters reported.
People can get exposure without having exposure to a singular stock…. It’s going to be a less volatile way of having exposure to something like SpaceX.
The change also eliminated a previous requirement that at least 10% of a company’s shares be publicly traded before the index would consider it.
SpaceX expects its public float to land between 3% and 5%, well below the 5% to 10% minimum free float historically required by most major indexes, SpotGamma noted.
Money reports that companies historically needed three to 12 months of trading before joining the Nasdaq-100, and at least 12 months for the S&P 500.
Neil McDonald told the publication that within 15 days of its listing, SpaceX is likely to rank as the seventh-largest component of the Nasdaq-100.
The S&P 500 held the line on fast-tracking SpaceX’s entry
S&P Dow Jones Indices had considered cutting its seasoning requirement from 12 months to 6 months and waiving the profitability test for newly public mega-cap companies.
On June 4, the index provider rejected its own proposal, keeping the 12-month seasoning period, four-quarter profitability test, and minimum float standards unchanged, Bloomberg reported.
That decision means SpaceX cannot enter the S&P 500 until mid-2027 at the earliest, and only after demonstrating four consecutive quarters of positive earnings.
Nasdaq and FTSE Russell both moved to accommodate SpaceX, according to SpotGamma, leaving S&P Dow Jones as the only major index provider to uphold traditional listing standards.
The S&P 500 is the foundation for roughly $20 trillion in indexed and benchmarked assets worldwide, according to S&P Dow Jones Indices’ most recent annual survey, making its inclusion decisions deeply consequential for passive investors.
“We’ll see whether this turns out to be a wise choice,” Bloomberg Intelligence Senior Exchange-Traded Fund Analyst Eric Balchunas posted on X after the announcement.

A $1.75 trillion valuation built on nearly $5 billion in losses
SpaceX’s finances could pose additional risk for investors whose retirement savings are in index funds, since those funds may automatically buy SpaceX shares.
The company reported a net loss of $4.94 billion in 2025 on revenue of $18.67 billion, according to its Securities and Exchange Commission filing.
Much of the loss came from the artificial intelligence unit that SpaceX acquired through its February all-stock merger with Musk’s xAI startup.
Losses accelerated in the first quarter of 2026, when SpaceX posted a $4.28 billion net loss in a single three-month period ending March 31.

Morningstar initiated coverage of SpaceX with a fair value estimate of $780 billion, roughly 55% below the company’s $1.75 trillion target.
The firm acknowledged SpaceX’s dominance in launch services but concluded that the market is pricing the company’s artificial intelligence ambitions far too generously.
Bloomberg Intelligence has projected roughly $20 billion in passive-fund demand tied to SpaceX, while other analysts’ estimates of near-term mechanical buying from Nasdaq-100 trackers alone range from $22 billion to $27 billion, according to the Motley Fool.
With S&P 500 inclusion now pushed to 2027 at the earliest, an additional wave of forced buying tied to that index has been deferred.
What does forced buying mean for your retirement account?
Index funds are built to mirror their benchmarks exactly, which means the funds in your retirement account cannot decline to buy a newly added stock.
Scott Richie, an investing expert at the financial analytics firm Stoculator, told Newsweek that index funds track whatever the index tracks, with no room for selectivity.
“A small slice of any single company, up or down, won’t make or break your retirement,” Richie also explained to Newsweek.
In addition, target-date portfolios will feel an even smaller effect because they carry bond allocations alongside stock holdings, Zachary Evens, a passive strategies research analyst at Morningstar, told InvestmentNews.
Most 401(k) exposure would likely come through diversified funds rather than direct stock ownership, added Mark Johnson, a faculty fellow in investments and portfolio management at Wake Forest University.
Pension fund leaders from New York and California have pushed back more forcefully, calling SpaceX’s governance structure extreme and heavily tilted toward management.
Musk will hold roughly 82.4% of the voting power after the offering, NBC News reported, a level of control that has drawn scrutiny from major institutional investors.
Because index funds are designed to mirror their benchmarks, they will automatically acquire SpaceX shares when the company is added. Active fund managers, in contrast, can decide for themselves whether to buy the stock.
