SpaceX completed the largest initial public offering in financial history on June 11, 2026, pricing 555.6 million shares at $135 each and raising $75 billion – nearly three times the funds generated by Saudi Aramco in its record 2019 IPO. The company, founded by Elon Musk in 2002, began trading on the Nasdaq the following day under the ticker SPCX, opening at a valuation of $1.77 trillion and closing at $161 per share – a gain of 19 percent from the IPO price on its first session. The debut placed SpaceX above Tesla by market capitalization on day one, making it one of the most valuable companies in the world the moment regular trading began.

The session high on June 12 reached $168.75 per share, a 25 percent premium over the IPO price, briefly pushing SpaceX’s implied market capitalization to approximately $2.21 trillion. That intraday peak made SpaceX, at least momentarily, the second-most-valuable publicly traded company on earth. The stock settled back to close at $161, giving the company a first-day market cap of roughly $2.1 trillion. Investor demand during the roadshow was described by underwriters as unprecedented, with the book multiple times oversubscribed across institutional and retail allocation pools.

$75 Billion Raised: How SpaceX Broke the IPO Record

The previous record for funds raised in a single IPO was held by Saudi Aramco, which raised $24.9 billion when it listed on the Tadawul exchange in Riyadh in December 2019. SpaceX’s $75 billion raise eclipsed that figure by a factor of three, reflecting both the company’s scale – it now handles the majority of orbital launch activity in the United States – and the extraordinary investor appetite for exposure to both the commercial space sector and Elon Musk’s broader industrial portfolio. The company’s Starlink satellite internet business, which has grown to more than four million paying subscribers globally, was cited by analysts as the clearest near-term revenue driver and the primary justification for the premium valuation at which the stock priced.

SpaceX’s bankers priced the deal at the high end of an already elevated range after gauging demand during two weeks of roadshow presentations to institutional investors in New York, London, and San Francisco. The $135 price valued the company at roughly $1.77 trillion on a diluted basis, which, as analysts were quick to note, put it in the same tier as Nvidia’s historic market cap surge in terms of the absolute scale of market value concentrated in a single company. Goldman Sachs and Morgan Stanley were joint lead underwriters on the offering.

Starlink Revenue and the Falcon 9’s Role in SpaceX’s Valuation

The core question any investor had to answer before the IPO was whether SpaceX’s valuation was justified by its underlying financials. The company reported revenue of approximately $15 billion for the twelve months preceding the listing, with Starlink representing the fastest-growing segment and the Falcon 9 launch business generating the largest share of gross margin. SpaceX has flown the Falcon 9 more than 400 times, with the rocket’s reusable first stage having achieved more than 300 reflights across the fleet. The maturity of the Falcon 9 program means its marginal cost per launch has fallen to levels that no competitor can currently match, giving the company a durable structural advantage in commercial satellite deployment, NASA crew and cargo missions, and Department of Defense launches.

Starlink, which has deployed more than 7,000 satellites and now covers most of the inhabited world, generated more than $8 billion in annualized revenue at the time of the IPO filing. The segment’s economics improve with each additional subscriber since the constellation’s capacity is largely fixed – the incremental cost of serving an additional customer is low once coverage is established. Analysts modeling SpaceX’s next five years placed significant weight on Starlink achieving 10 to 15 million subscribers, a target the company’s management suggested was achievable given the pace of subscriber additions in 2025 and early 2026, particularly in emerging markets where terrestrial broadband infrastructure is sparse.

The Starship Factor: Future Growth Priced In

A significant portion of the SpaceX valuation premium reflects expectations about Starship, the fully reusable next-generation launch vehicle that the company has been developing and testing at its Boca Chica, Texas facility. Starship’s intended launch cost target of approximately $10 million per flight – far below any existing rocket – would, if achieved at scale, restructure the economics of orbital access in ways that could open markets that are currently not commercially viable. SpaceX’s vision of using Starship to deploy the next generation of high-capacity Starlink satellites could further accelerate the satellite internet business’s already fast growth trajectory.

The IPO prospectus was careful to characterize Starship targets as aspirational, noting that the vehicle has not yet completed a commercial mission and that development costs remain substantial. The interest rate environment, with the Federal Reserve holding rates at 3.50 to 3.75 percent through mid-2026, has made growth-stock valuations more sensitive to execution risk than they were during the near-zero rate period of 2020 to 2022. SpaceX’s bankers structured the deal to give investors optionality on Starship upside while pricing primarily on the demonstrated cash flow from Falcon 9 and Starlink.

Musk’s Stake and Governance Structure

Elon Musk retains a majority voting stake in SpaceX through a supervoting share structure that gives him effective control over the company’s strategic direction despite owning a minority of the economic interest. The dual-class structure was a point of scrutiny during the IPO roadshow, with some institutional investors expressing concern about governance protections for public shareholders given Musk’s simultaneous leadership of Tesla, X, xAI, and the Boring Company. SpaceX addressed those concerns in its prospectus by establishing an independent board committee structure and committing to certain disclosure requirements around related-party transactions.

The IPO marks a new chapter for a company that Musk founded with the stated goal of making humanity multiplanetary. Whether that long-term mission translates into shareholder returns over a ten-year horizon will depend on how aggressively SpaceX can execute on Starship, how quickly Starlink can scale, and whether the company can maintain its technical lead over emerging launch competitors in both the United States and China. For now, the $75 billion raised gives SpaceX a financial foundation that should fund its ambitions for years without needing to return to public markets for additional capital. The defense sector competition SpaceX faces from Boeing and others for government launch contracts adds another dimension to the company’s commercial outlook in the years ahead.
