A major liquidity event expected to create a whole new roster of multi-millionaires, the SpaceX IPO promises to be one of the stock market highlights of the year. Whether its valuations live up to the billing is up for debate.

As doors have opened for applications for the record-breaking SpaceX IPO – the first trading day is slated for June 12 – the question arises as to how its potential $1.8 trillion price tag can be justified.

Joakim Agerback, lead portfolio manager at the Finserve Global Security Fund – an actively managed defense fund run by Sweden’s Finserve – also holds space stocks and cybersecurity equities. The firm is not enthusiastic about the stock’s valuation assumptions. (The fund was launched in 2019.)

SpaceX’s $1.8 trillion valuation “leaves little room for anything short of exceptional execution and total dominance in the sector for a long period of time,” Agerback said in a note late last week. 

The IPO will be one of the banner stock market events of the year. Agerback said tycoon Elon Musk’s business will help lift a wider circle of space-focused businesses.

“For long-term investors, the bigger opportunity may not be the IPO itself but the broader space economy it helps validate and a broader approach may therefore be preferable, with SpaceX serving as an important component of their space allocation,” he said. Agerback gave examples such as Rocket Lab, AST SpaceMobile, Planet Labs, Leonardo, OHB, SES, Eutelsat, Hanwha Aerospace, SKY Perfect JSAT and iQPS.

In a June 5 report, the Wall Street Journal quoted sources saying that SpaceX’s revenue could reach $3.4 trillion in 2040 – based on a Morgan Stanley analysis shared with top investors. Research analysts at Goldman Sachs and Morgan Stanley both projected SpaceX’s revenue would be near $160 billion in 2028, the WSJ report noted. The banks are among 21 of the lenders involved in the IPO.

As noted here, IPOs can be significant liquidity events, minting new millionaires. As the WSJ reported, beneficiaries of the share float will include engineers and other white-collar workers as well as the technicians who build the company’s rockets, and even baristas and other salaried employees who work at SpaceX campuses in California, Texas and Florida. Insiders and employees cannot usually sell pre-IPO shares for several months; the newspaper said SpaceX has provisions that could let some staff sell small amounts as soon as July. 

SpaceX filed its IPO with the Securities and Exchange Commission on May 20.

There is speculation over how to value SpaceX’s shares considering financial disclosures that seem minuscule by comparison. SpaceX had a net loss of $4.28 billion on revenue of $4.69 billion for the first quarter, widening from a net loss of $528 million on revenue of about $4 billion a year earlier, the filing shows.

Agerback said there will be strong retail and institutional demand for SpaceX and considerable near-term stock volatility.

“For long-term investors, the bigger opportunity may not be the IPO itself but the broader space economy it helps validate and a broader approach may therefore be preferable, with SpaceX serving as an important component of their space allocation,” he said. Agerback gave examples such as Rocket Lab, AST SpaceMobile, Planet Labs, Leonardo, OHB, SES, Eutelsat, Hanwha Aerospace, SKY Perfect JSAT and iQPS.

Other prominent IPOs of recent years include Saudi Aramco (2019); Alibaba, Agricultural Bank of China, Meta Platforms, Bank of China, Uber Technologies, Life Insurance Corp of India, Rivian Automotive, NTT Mobile, and Porsche (source: Wall Street Journal). The world’s largest firm by market cap is Nvidia, which floated on the stock market in 1999.

“SpaceX has leadership in launch economics, vertical integration and the self-reinforcing advantages created by Falcon9. Together, these have established a competitive position that is unlikely to be challenged in the near term. Combined with the support of the world’s largest space ecosystem, these advantages justify a substantial premium,” Agerback said. 

“That said, the current valuation appears difficult to fully justify. At roughly $1.8 trillion, SpaceX is being valued not only as the dominant space infrastructure company but also as a leading AI platform. Based on [full year 2025] revenues, the company would trade at 97x, a level that remains exceptionally demanding,” he added. 

In an update this week, The Motley Fool financial markets site said the "10 largest US IPOs in history have collectively underperformed the S&P 500 by a wide margin."
