Initial public offering of SpaceX

Prospectus valuation and underwriter metrics

Goldman Sachs, Morgan Stanley, BofA Securities, Citigroup and ⁠JPMorgan were named on June 2, 2026, as the joint underwriters for the offering, leading ​a syndicate of global investment banks underwriting the deal. Fees were to be less than 0.75% on the IPO, or about $500 million.^[34] Typically, fees range between 4 to 7%.

In a move which Reuters qualified as "take-it-or-leave-it stock pricing", SpaceX's IPO price was set at $135 per share even before investor roadshows typically used by Wall Street to test demand ‌and set a price range.^[35]

SpaceX's $135 per share implies an enterprise valuation of $1.77 trillion and a first-day market capitalization of approximately $2.1 trillion.^[2] The prospectus relied heavily on a total addressable market (TAM) of $28.5 trillion—described as the largest in "human history"—of which roughly 90 percent ($25.6 trillion) was attributed to artificial intelligence through SpaceX's recently acquired xAI subsidiary.^[36][7]

The underwriters advanced revenue projections far exceeding independent estimates: Goldman Sachs privately projected $474 billion in total revenue by 2030 (versus $18.7 billion in 2025),^[7] while Morgan Stanley forecast $330 billion, ^[37] and $3.4 trillion by 2040.^[7] SpaceX pointed to its compute contracts with Anthropic ($1.25 billion per month) and Google ($920 million per month) as evidence of AI revenue traction, with one analyst noting these added "$26 billion in annual run rate between the SEC [Security and Exchange Commission] filing date and the first trade".^[38][39] Both contracts, however, carried 90-day termination clauses.^[40] At the offering price, SpaceX traded at approximately 67 times trailing sales, roughly three times Nvidia's multiple at the time.^[10]

Analyst valuations and the overvaluation debate

Independent analysts converged on substantially lower valuations, with the AI-attributed TAM as the main point of contention.

"Dean of valuation" Aswath Damodaran separately modelled each of the launch, Starlink, and xAI business segments to arrive at an enterprise value of approximately $1.3 trillion. Noting xAI's huge losses, he questioned its ability to achieve a significant share of the $26 trillion total addressable market as "beyond plausible".^[36] However, Damodaran acknowledged the stock would trade very heavily, based on mood and momentum".^[36]

Morningstar placed fair value at $780 billion.^[10] Analysts Nicolas Owens and Suryansh Sharma described SpaceX as "significantly overvalued", and that in particular xAI's lack of clear competitive advantage was a "material threat of value destruction". Their most optimistic valuation of $1.97 trillion was predicated on full Starship reusability and commercially viable orbital data centers, to which they assigned a 7% probability of achieving.^[44] Owens and Sharma predicted the share price would rise in the near-term given the small public float and unprecedented fast-track Nasdaq-100 inclusion, but advised long-term investors to await better opportunities further down the line.^[10]

A structural critique from Cape Fear Advisors argued that SpaceX's actual AI position, mapped against identifiable sub-markets, supported at most $200–500 billion valuation – "approximately one to two percent of the $25.6 trillion AI TAM allocation the S-1 attests to". Cape Fear analysts noted that advertising-subsidized AI was structurally dominated by Google, that xAI's annualized revenue of roughly $500 million was a fraction of Anthropic's $30 billion and OpenAI's $25 billion in the enterprise market, and that SpaceX's strongest AI claim lay in defense and deployment, where its structural position was analogous to Palantir's in 2020.^[42]

Short-seller Jim Chanos described the offering as "very much a 'don't look at the man behind the curtain' situation", focusing on xAI's apparent pivot from developing frontier AI models to acting as a neocloud – a provider of GPU compute for third parties – which he characterized as "a commodity business valued far lower on the public markets".^[7] Hedge fund manager Michael Burry wrote on Substack that "nothing in that S-1 suggests it is worth $1 trillion let alone $2 trillion" and that any post-IPO gains would "be on hype and technicals".^[7]

Ross Gerber of Gerber Kawasaki, an existing SpaceX shareholder, described the IPO valuation as alarming given the company had been valued at $400 billion just thirteen months earlier. He attributed the extremely high price for this stock to confidence in Musk personally rather than conventional financial metrics.^[7]

Supporters countered that the Anthropic and Google contracts validated xAI's positioning, and that Starlink – the only profitable segment, with quarterly revenue of $3.26 billion and subscribers projected to grow from 10 million to nearly 17 million during 2026 – provided a solid commercial foundation.^[10]

Inclusion in market indexes

Being included in a major stock market index can significantly increase demand for a company's shares because institutional asset managers must buy shares in order to mirror the index.^[45] Rule changes about when SpaceX was to be included in an index were controversial because SpaceX was to be extremely expensive based on metrics like the price-revenue ratio, and skeptics were concerned that millions of Americans' retirement plans which invest using indexes would be exposed too soon to a volatile stock.^[45]

As of March 2026, the New York Stock Exchange and Nasdaq were competing for the IPO listing, and SpaceX requested early inclusion on the Nasdaq-100 index as a condition for listing on Nasdaq.^[20] On March 30, Nasdaq changed its rules to allow SpaceX and other large companies to be listed in the index 15 trading days after their IPO, instead of a minimum of three months and up to one year after.^[45][46] But because only 5% of SpaceX's shares would initially be available to the public, Nasdaq's float-adjustment rules gave SpaceX a weight of 1% in the index, versus 5% weight without the rule, initially mitigating any swings in the SpaceX stock price.^[45] On May 15, SpaceX chose to list on Nasdaq.^[47]

On June 4, the S&P Global company reaffirmed no change to its rules which might have allowed SpaceX to be included earlier in the S&P 500 index. The rules require a company to be profitable under Generally Accepted Accounting Principles (GAAP) in its most recent quarter as well as for the sum of its most recent four quarters. SpaceX posted a net loss of $4.94 billion in 2025, and thus is not currently eligible for inclusion. However, S&P Global said it planned to modify its rules to allow SpaceX earlier entry into its less widely followed but broader S&P Total Market Index and Dow Jones U.S. Total Stock Market Index. Index provider FTSE Russell also changed its rules to allow SpaceX to be included earlier in both the Russell U.S. Equity Indexes and the FTSE Global Equity Index Series.^[48]

Index inclusion, manufactured scarcity, and price dynamics

After competition from the New York Stock Exchange for the IPO listing, and Musk's insistence that SpaceX be allowed early inclusion on the Nasdaq-100 index,^[20] Nasdaq changed its rules on March 30 to shortening the "seasoning period", allowing SpaceX and other large companies to be listed in the index 15 trading days after their IPO, instead of a minimum of three months and up to one year after that had applied previously to listings.^[45][46] On May 15, SpaceX chose to list on Nasdaq.^[47]

Critics argued that the combination of rule changes engineered around the IPO artificially inflated SpaceX's opening price at the expense of retail investors and retirement savers.

The central mechanism was the deliberate restriction of the public float. Only around 5 percent of SpaceX shares were made available to the public at flotation—far below the 10 percent minimum typically required by the SEC for a public listing, for which SpaceX obtained a waiver—while comparable large-caps such as Nvidia and Apple have over 90 percent of shares in public circulation.^[4] The one mitigation is Nasdaq's float-adjustment rules, which would give SpaceX an initial weight of 1% in the index, versus 5% weight previously, theoretically attenuating wild swings in the price of index funds.^[45]

Scott Galloway, professor of marketing at NYU's Stern School of Business, argued that this amounted to "the greatest degree of manufactured scarcity we've ever seen in an IPO": with some $30–50 billion in additional demand expected from index funds that would be forced buyers under new inclusion rules, constraining supply to a tenth of a typical float would produce extreme upward price velocity on debut.^[49] Similarly, David Brown, associate professor of finance at the University of Arizona, echoed the sentiment, but suggested that the forthcoming massive IPOs of Anthropic and OpenAI should cause index funds to deeply reflect on the timing for index inclusion them because: “For most investors, that’s where it’s going to hit”.^[4]

The Nasdaq rule change compounded this effect. Having made early Nasdaq-100 inclusion a condition of listing on the exchange, SpaceX secured entry to the index just 15 trading days after its IPO, triggering mandatory purchases by every fund tracking the index.^[1] Nasdaq further applied a threefold multiplier to SpaceX's index weight to compensate for its low float, so holders of the QQQ ETF received a disproportionately large exposure to the stock.^[4] The CRSP US Total Market Index, used by Vanguard as a benchmark for its broad index funds, added SpaceX just five trading days after the IPO.^[4] The Russell 1000 followed within approximately a week. Only the S&P 500 held to its existing rules, which require 12 months of public trading and four consecutive profitable quarters before inclusion.^[1]

Wealth transfer and retail investor risk

Several commentators were concerned about the cumulative effect of these mechanisms as a transfer of wealth from ordinary investors to SpaceX insiders. Professor Galloway estimated that SpaceX could account for 4–6 percent of Nasdaq-100 and MSCI index products, forcing trillions of dollars in assets under management to rush to buy.^[49] Robin Wigglesworth, editor at the Financial Times, was more pointed still: "When you see an IPO give a far larger allocation to ordinary investors, it's usually a sign that they can't get professional investors to buy it at that price. The price is nuts."^[6]

Eric Gardner, contributor at the nonprofit newsroom More Perfect Union, argued that Musk had "financially engineered the IPO as a massive wealth transfer from everyday investors to insiders": early investors – namely backers of Musk's buyout of Twitter and other shareholders of X and xAI – would be able to cash out at the inflated IPO price, while retail investors holdering index-fund investments would be compelled to buy through index purchasing.^[6] George Pearkes, an investment strategist quoted in Gardner's report, commented: "Every piece of evidence we have is that the IPO is being engineered to rise very rapidly after it prices, and then fall very dramatically after that. That is a recipe for retail investors, especially, to take large losses."^[6]

In practice, the immediate impact on individual retirement accounts was modest. The CRSP float-adjusted weighting gave SpaceX roughly 0.1 percent of a total US market index fund at opening prices, meaning a $50,000 index fund position would hold approximately $57 of SpaceX stock – less than a tenth of the same portfolio's Tesla exposure.^[4] Rodney Comegys, chief investment officer at Vanguard Capital Management, was comforted by the fact that "even mega IPOs will enter broad indexes at very small weights, so the near-term impact on 401(k)s is limited."^[4] However, index weight is expected to grow substantially as insider lock-up periods expire and more shares enter circulation.

Underwriter conduct: Grok subscriptions and client penalties

Two aspects of the IPO process drew attention for the pressure exerted on market participants. In April 2026 the New York Times reported that Musk had required the banks managing the IPO to purchase subscriptions to Grok as a condition of involvement in the deal. Some banks had agreed to spend tens of millions of dollars annually on the product and had begun integrating it into their IT systems.^[8]

Separately, several underwriting banks and brokers reportedly warned clients that participation in the SpaceX IPO would be conditional on past behavior: those who had previously flipped IPO shares – selling shortly after debut to capture the opening pop – risked being excluded from the allocation. The practice of penalising short-term sellers to protect IPO price stability is not uncommon, but its application to an offering of this scale and public profile attracted additional scrutiny given the broader concerns about retail investor access and pricing fairness.^[49]
