SpaceX IPO valuation risk is the defining question for investors as the rocket and satellite company begins trading on Nasdaq on 12 June 2026. Around $75bn has been raised at a headline valuation of $1.77trn, the largest implied market capitalisation at listing of any US company.
SpaceX, formally Space Exploration Technologies Corp., filed its S-1 registration statement with the SEC on 20 May 2026. The filing gave public investors their first detailed look at the company’s finances.
Starlink Is Carrying the Company
The Connectivity segment, Starlink, generated $11.4bn in revenue and $4.4bn in operating income in 2025, accounting for around 61% of total group revenue, according to Via Satellite’s analysis of the S-1.
Starlink revenue grew roughly 50% year-on-year in 2025. Its share of SpaceX’s total revenue climbed further in Q1 2026, reaching 69%, with the segment generating $3.26bn in revenue and $1.19bn in operating income for the quarter, Yahoo Finance reported. The trajectory suggests the segment has not yet reached its growth ceiling.
The subscriber base recently surpassed 12 million active users, up from 9 million a year earlier, across more than 160 countries and territories. The US government accounts for around 20% of SpaceX’s total group revenue.
Beyond Connectivity, the Space segment, which covers launch services and NASA crew contracts, generated $4bn in revenue in 2025. The AI segment, brought in after the acquisition of xAI, contributed a further $3.2bn. SpaceX spent nearly $3bn in R&D on Starship development during the year, Via Satellite reported, citing the S-1.
The company intends to put more than 100,000 satellites into orbit over time. Next-generation V3 hardware under development is described as 10 to 20 times more powerful than existing satellites, opening the path to higher-bandwidth services that could underpin new revenue streams.
Heavy Losses Track the AI Build-Out
Group revenue jumped 33% to $18.7bn in 2025. The company recorded a net loss of $4.9bn for the year, reversing profitability from the prior year. Loss from operations across the group was $2.6bn, Via Satellite reported.
The AI unit’s infrastructure build is the main driver. Strip it out and SpaceX has generated positive operating cash flow for roughly a decade. Analysts do not expect the consolidated group to return to profitability for at least two more years given the current pace of spending.
Morningstar reports SpaceX raised more than $10bn in venture capital funding over its life as a private company since Elon Musk founded it in 2002. The Nasdaq listing ends more than two decades of private operation.
The longer-term upside case includes data centres in space, where electricity and cooling are theoretically cost-free. The engineering hurdles between concept and commercial operation are substantial, and no timeline is certain.
SpaceX IPO Valuation Risk: What the P/S Multiple Signals
SpaceX IPO valuation risk crystallises in one number: an implied price-to-sales (P/S) ratio of approximately 94, derived from the $1.77trn valuation against $18.7bn in 2025 revenue. A premium first-day open could push that multiple above 120.
A P/S ratio above 10 is generally considered stretched for most listed businesses. At close to 100, execution has to be near-perfect. Any miss against Starlink’s growth expectations, or delay in reducing AI losses, is likely to prompt a sharp rerating.
The scale of the valuation is illustrated by comparison. The $1.77trn figure exceeds the combined market capitalisation of HSBC, AstraZeneca, Shell, Rolls-Royce, Unilever, BP, BAE Systems, NatWest, Diageo, Tesco, Vodafone, and BT.
The bull case rests on Starlink’s momentum holding. Revenue in the Connectivity segment grew roughly 50% in 2025 and its share of total revenue was still rising in Q1 2026. If that trajectory continues and AI losses begin to narrow, the forward multiple compresses quickly and the entry price looks less extreme.
The bear case is direct: SpaceX IPO valuation risk is priced on the assumption that a company burning cash at scale will sustain growth rates rarely achieved by businesses of this size.
The first live test after listing arrives when SpaceX reports its Q2 2026 results. Starlink’s revenue and operating margin for the quarter will set the tone for how the market values the stock into the second half of the year.
