SpaceX has formally initiated its journey toward the public markets, with its IPO prospectus outlining an ambitious commercial vision. The prospectus filed on May 20 reveals that Starlink, the company's core business, has reached 10 million subscribers, generating annual revenue exceeding $11 billion. The company plans to deploy a constellation of orbital AI computing satellites by 2028 and is developing infrastructure for the Moon and Mars. Furthermore, Elon Musk's restricted stock award is directly tied to specific SpaceX valuation milestones and is also linked to the progress of establishing a permanent human colony on Mars. The final vesting condition requires the colony to sustain a population of at least one million residents. This structure implies that Musk's ability to realize his largest potential equity payout is contingent upon humanity successfully achieving interplanetary settlement. For the market, a central question surrounding this IPO is the rationale behind its valuation. If the company achieves a valuation of $1.5 trillion, its price-to-sales ratio would reach approximately 80x. This significantly exceeds the aggregate level of around 7x sales for the top 15 U.S. companies by market capitalization, especially considering SpaceX reported a net loss of $4.9 billion for 2025.
Starlink Forms Revenue Foundation, Subscriber Base Doubles in a Year
Starlink currently serves as the financial backbone for SpaceX. The prospectus indicates that as of the end of March 2025, Starlink's satellite internet service had approximately 10 million subscribers, doubling from the previous year. The division encompassing the Starlink broadband business recorded over $11 billion in revenue for the full year 2025, constituting the majority of the company's total revenue of about $18.7 billion. SpaceX lists telecom giants like AT&T and Verizon as competitors in the prospectus, stating that Starlink has the potential to capture a larger share of the high-speed internet market from these incumbents. The company currently operates about 10,000 satellites in low Earth orbit and emphasizes that "Starlink can provide broadband connectivity to any location on Earth."
Orbital AI Computing Satellite Constellation, Deployment Targeted for 2028
Beyond Starlink, SpaceX positions orbital AI computing as its next major growth engine in the prospectus, with plans to begin deployment as early as 2028. The company states:
Orbital AI computing is a profoundly challenging technical problem, and we believe we are the only company with a commercially viable path to building orbital AI compute capability at scale.
The prospectus notes that achieving this goal is critically dependent on the Starship rocket meeting its performance targets to enable economically feasible on-orbit deployment. Proceeds from this financing will be used for AI computing infrastructure, satellite launches, and related business expansion. Additionally, SpaceX disclosed plans in the prospectus to establish manufacturing infrastructure on the Moon and Mars, further detailing its long-term interplanetary strategy.
Substantial Financial Losses, Valuation Thesis Tests Investors
SpaceX's financial profile is notably distinct among the mega-cap tech companies seeking to go public. In 2025, the company generated approximately $18.7 billion in revenue but incurred a net loss of $4.9 billion. In comparison, Meta, a company with a valuation in a similar range, reported revenue over 11 times that of SpaceX last year and a net profit of $60 billion. If the IPO valuation ultimately settles above $1.5 trillion, SpaceX's price-to-sales ratio would be around 80x. This contrasts with the aggregate price-to-sales ratio of approximately 7x for the top 15 U.S. companies by market capitalization. This valuation logic bears resemblance to another of Musk's companies, Tesla. Despite minimal profits in 2025 due to massive investments in AI, humanoid robots, and Robotaxi, Tesla's stock trades at a forward P/E ratio nearing 400x. Analysis suggests that investors backing SpaceX or Tesla are essentially betting on Musk's ability to convert current massive investments into significant value in the distant future.
