SpaceX’s landmark listing this week is set to test the “Elon premium” that has made Tesla one of the most highly valued U.S. companies and a must-have among retail investors.
The rocket company led by Elon Musk is targeting a valuation of US$1.77-trillion in its record-setting IPO, which would make it the seventh-biggest publicly traded U.S. company by market value.
Musk’s fans contend that his track record makes buying SpaceX shares at the IPO a no-brainer, but some investors and analysts say the expensive multiple it is expected to trade at makes the risk too high.
“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.
The belief that Musk can create outsized value has long supported lofty valuations across his business empire.
John Plassard, head of investment strategy at Swiss-based wealth manager Cité Gestion, a Tesla shareholder, said he was comfortable paying 20 per cent-30 per cent more for shares in a well-run Musk company than for a comparable rival.
However, the skepticism toward SpaceX underscores that even Musk’s star power may not be enough to overcome concerns about its price tag, as some investors balk at paying prices that assume years of rapid growth and flawless execution.
SpaceX posted a net loss of US$4.94-billion in 2025, but its targeted valuation is 94.53 times sales over the same period, according to Reuters calculations.
By comparison, Tesla trades at 16.73 times its 2025 sales, according to data compiled by LSEG.
“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.
Tesla’s success in turning electric vehicles from a niche product into a mainstream industry has helped establish its credibility, making it the world’s most valuable automaker.
“If you’re betting on Elon the man, why not have both stocks in your portfolio?” said Adam Sarhan, chief executive of 50 Park Investments.
However, Sarhan said he would not buy SpaceX immediately after the debut, and would wait for a few months for the price to settle before making a decision.
One of the biggest questions facing SpaceX is its AI business, which relies on technology that has yet to be proven, such as orbital data centers.
“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.
Grok, the chatbot developed by xAI, also trails more established rivals from OpenAI and Anthropic.
“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.
Last week, Owens gave SpaceX a valuation of US$780-billion, less than half of what it is targeting in the IPO.
A possible merger between SpaceX and Tesla has also been floated, though most investors say any such deal would be complex.
“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.
Justus Parmar, CEO of Fortuna Investments, which owns both Tesla and SpaceX, sees Tesla’s manufacturing prowess as the impetus for an eventual merger.
“When he’s developing the moon and beyond, you’re going to need real manufacturing capabilities,” he said.
But this time, investors may be less worried about Musk being distracted, because of his continued commitment to Tesla.
Having managed both companies in parallel for years, he is unlikely to become materially less involved in the automaker simply because one of his other ventures has gone public, analysts say.
Since SpaceX confidentially submitted paperwork for its IPO, Tesla shares have gained 10 per cent, unlike in the past when fears that Musk was spreading himself too thin weighed on the stock.
FThe EV maker’s stock fell more than 30 per cent between Twitter’s board approving his takeover bid and the deal closing. Shares also declined nearly 16 per cent around the SolarCity merger in 2016.
Tesla’s legions of retail investors are also sizing up the SpaceX IPO.
Alexandra Merz, a self-described “all-in Tesla investor” since March 2020, said she would need to sell Tesla shares to buy SpaceX stock, which would trigger taxes.
She would rather stay invested in Tesla “with the conviction that there is a merger on the horizon,” she added.
