SpaceX’s proposed public debut and its eye-catching target valuation have brought renewed scrutiny to what investors call the "Elon premium" - the tendency for markets and retail investors to pay extra for companies led by Elon Musk. The rocket company is aiming for a $1.77 trillion valuation in its IPO, a figure that would place it among the top publicly traded U.S. firms by market capitalization if achieved.
Supporters of Musk argue that his past successes create a compelling case for participating in the IPO. Yet several market participants and analysts question whether the valuation adequately reflects the risks embedded in SpaceX’s numbers and its more speculative business lines.
"Its fundamentals are really tough. If there weren’t lofty expectations, there wouldn’t be an IPO here," said Ed O’Gorman, CEO at River Wealth Advisors, which has invested in Tesla. That view underscores a core tension: confidence in Musk’s ability to generate outsized value on one hand, and skepticism about paying for growth that may not materialize on the other.
Some investors privately accept paying a premium for Musk-led enterprises. John Plassard, head of investment strategy at Swiss-based wealth manager Cité Gestion and a Tesla shareholder, said he felt comfortable paying 20%-30% more for shares in a well-run Musk company than for a comparable rival. The argument is simple - the founder’s track record can justify an extra layer of valuation for a limited set of investors who buy the narrative.
Still, not everyone is persuaded that Musk’s reputation alone can validate SpaceX’s lofty sticker price. Reuters calculations show SpaceX’s targeted IPO valuation would equate to roughly 94.53 times its 2025 sales, while the company reported a net loss of $4.94 billion in 2025. By comparison, Tesla trades at about 16.73 times its 2025 sales, according to LSEG data compiled in the same analysis.
Those relative multiples highlight why some market participants see the offering as contingent on years of rapid expansion and near-perfect execution. "We see Tesla and SpaceX as complementary businesses. We feel confident that both of these companies can succeed," said Tejas Dessai, director of research at Global X, reflecting a view among investors who want exposure to both opportunities.
Other market voices recommend a more cautious approach. Adam Sarhan, chief executive of 50 Park Investments, said that if an investor is backing Musk personally, there is logic in owning both Tesla and SpaceX. Yet Sarhan added he would not rush into SpaceX immediately after its debut, preferring to wait several months and let the market set a clearer price.
Beyond headline valuation metrics, investors are scrutinizing portions of SpaceX’s business that rest on technology and commercial models that remain unproven. A prominent example is the company’s AI ambitions, which involve concepts such as orbital data centers - infrastructure that, critics argue, lacks real-world comparables and clear physics-based proof points.
"Space data centers that are very unproven. The physics is the biggest question mark of it all. How are you going to value something that you just simply cannot see or test or have any comparables to?" said Franco Granda, senior research analyst at PitchBook. That sentiment captures an important challenge for valuing long-term, technology-driven propositions whose economics are still hypothetical.
On the AI front, Grok - the chatbot created by xAI - is also viewed as trailing better-established rivals. "We don’t see Grok as one of the leading AI labs today, and while we modeled a range of outcomes for this portion of the business, none of them meaningfully add to or subtract from our valuation of the AI business," said Nicolas Owens, equity analyst at Morningstar. Owens recently placed a valuation on SpaceX of $780 billion, a figure well below the IPO target and less than half of the company’s desired valuation.
Speculation about corporate combinations adds another dimension to investor debate. Some market commentators have floated the idea of a future merger between SpaceX and Tesla, though most observers say such a transaction would likely be complicated and uncertain. "At some point in the future, in the event of a successful IPO, Tesla will get absorbed into SpaceX," said Michael Hewson, senior market analyst at iForex - a view that other investors regard as aspirational rather than imminent.
Justus Parmar, CEO of Fortuna Investments, which holds stakes in both Tesla and SpaceX, argued that Tesla’s manufacturing strength could be relevant if Musk’s ambitions expand into large-scale space-based operations: "When he’s developing the moon and beyond, you’re going to need real manufacturing capabilities," Parmar said.
For some investors, Musk’s continued involvement with Tesla lessens concerns that he might divert attention away from the automaker. Analysts note that Musk has managed multiple companies for years, and his commitment to Tesla appears intact. Since SpaceX confidentially filed for its IPO, Tesla shares have risen roughly 10%, a pattern that differs from past episodes when investor anxiety about Musk’s time allocation weighed on Tesla stock. For example, the EV maker’s shares fell more than 30% in the period between the Twitter board approving his takeover bid and the deal’s closing, and they declined nearly 16% around the time of the SolarCity merger in 2016.
Among dedicated retail shareholders, reactions vary. Alexandra Merz, who describes herself as an "all-in Tesla investor" since March 2020, said she would have to sell Tesla shares to acquire SpaceX stock, a step that would trigger tax liabilities. She prefers remaining invested in Tesla for now, "with the conviction that there is a merger on the horizon." Her comments illustrate the trade-offs retail investors face when allocating capital between two closely linked, high-profile companies.
SpaceX’s IPO is poised to be a test of investor appetite for Musk-branded premium valuations, a stress test of how much extra investors will pay for perceived founder-driven upside. The debate centers on whether faith in Musk’s track record should outweigh the concrete valuation metrics in front of investors today - metrics that include a recent multi-billion-dollar loss and a price-to-sales multiple far above that of Tesla.
As the market digests the offering, investors will be watching both short-term pricing dynamics and longer-term answers to questions about the economics and technical feasibility of SpaceX’s more speculative ventures.
