SpaceX’s Starship Advantage Faces an Extreme IPO Valuation Test

Jay Ritter framed SpaceX’s prospective IPO around a tension: the company may have a genuine technological lead, but the public-market valuation being discussed would require exceptional execution. Asked by Caroline Hyde whether the market capitalization would amount to vindication, Ritter agreed with the premise that “an awful lot has to go right,” while calling SpaceX “a great company.”

The core of his positive case was not simply that Starship is ambitious. It was that Starship’s complexity may itself be a competitive advantage. Ritter described the vehicle as “an incredible engineering feat” and argued that its difficulty makes it hard for a rival to build something comparable. If SpaceX can lower launch costs as much as expected, he said, that would give the company “a big technological lead over any potential competitor.”

That launch-cost advantage matters because it feeds directly into Starlink. Ritter said SpaceX would be able to put Starlink satellites into low Earth orbit and offer internet access at much lower costs than competitors. In his account, Starship and Starlink are linked: the launch system is part of the economics of deploying and operating the satellite network.

Bloomberg displayed a chart placing SpaceX among the largest public companies by market capitalization, with the company shown alongside Nvidia, Alphabet, Apple, Microsoft, Amazon.com, Broadcom, and Tesla. The visual’s framing was explicit: “SpaceX’s potential spot among heavyweights.” It underscored the scale of the claim being tested by the IPO discussion, not just the company’s engineering profile.

Ed Ludlow asked Ritter what would be different about this IPO and what would be the same as offerings he has studied over his career. Ritter’s answer was that the size alone would make it unusual. SpaceX, he said, would be “the largest private sector company ever to go public,” with a valuation “of something like 1.5 trillion dollars.”

Bloomberg’s on-screen expectations were even more aggressive in one respect: SpaceX was described as targeting as much as $75 billion in its listing, with a valuation above $2 trillion, and as poised to choose Nasdaq as its listing venue. The same graphic noted that a filing could include financial details such as revenue and net income.

Ritter distinguished SpaceX from the largest historical IPOs by the type of company coming to market. The biggest companies to go public in the past, he said, have generally been large state-owned enterprises with very large operations and profitability. SpaceX, by contrast, is being valued by the market and venture capitalists on the basis of “enormous potential future profitability.”

That distinction is central to his caution. The IPO would not merely ask investors to pay for an already mature profit stream. It would ask them to underwrite a future in which the company’s technical lead, launch economics, Starlink growth, and broader space ambitions convert into profits large enough to support one of the highest valuations ever attached to a newly public company.

Hyde pressed the valuation question through the lens of public investors. Companies are staying private longer, she noted, and arriving in public markets at extraordinary valuations. The issue is how much upside remains for investors who did not fund the company from its early stages.

Ritter answered with revenue and multiples. SpaceX had $18.7 billion in sales last year, he said, making it bigger by revenue than almost any tech startup or private company that had not already been public at the time of listing. But the valuation being discussed would still imply an unusually high price-to-sales ratio.

At a $1.5 trillion valuation, Ritter said, SpaceX would go public at roughly 80 times sales. He compared that with a small historical set: about 18 companies have gone public in the United States with inflation-adjusted revenue of at least $100 million a year and a price-to-sales ratio above 40. Among those companies, he said, the average stock performance has been disappointing for investors.

The point was not that SpaceX lacks scale. Ritter’s caution was that even a very large revenue base can look small relative to a $1.5 trillion market value. To justify that valuation, he said, “very big future profits have to be there.”

Bloomberg also placed SpaceX in a broader 2026 IPO context, showing reported value-raise estimates for three companies: SpaceX at $75 billion in June, Anthropic at $60 billion in the fourth quarter of 2026, and OpenAI in late 2026 with the amount marked “TBA.” The visual reinforced Hyde’s broader point: late-stage private companies are approaching public markets after accumulating very large private valuations and financing expectations.

Ludlow turned to what he characterized as repeated S-1 warnings: that SpaceX will be constrained by compute now and in the future, and that Starship has to work. He asked Ritter whether that language was merely boilerplate or something more substantive.

Ritter did not treat the concern as empty disclosure. His answer separated two possible sources of prospective profitability. On sending people to Mars, he said, “the profitability” is “very questionable.” But for Starlink, he said, the ability to get things moving in the foreseeable future could be “an enormous source of profits.”

That distinction narrows the part of the investment case Ritter emphasized. The Mars ambition may define part of SpaceX’s identity, but Ritter pointed to Starlink as a nearer-term source of potentially enormous profits, enabled by lower-cost launch. Starship still matters because the economics of Starlink depend on getting satellites into orbit efficiently. But the route to justifying the valuation, in his framing, depends on whether SpaceX can translate its launch-cost advantage into profits large enough to match the price.
