SpaceX Eyes Confidential IPO Filing in March, Targeting $1.75 Trillion Valuation
Elon Musk's rocket company moves toward what could become the largest public offering in history, testing a market that's shown renewed appetite for tech debuts.
SpaceX is preparing to file confidentially for an initial public offering as early as March, according to Bloomberg, putting the rocket and satellite company on track for a June listing that could raise more than $50 billion and eclipse all previous IPO records. The confidential submission mechanism allows SpaceX to submit its draft IPO registration to the US Securities and Exchange Commission without immediate public disclosure, giving the company flexibility to gauge market interest while minimizing early scrutiny.
Valuation Surge Driven by Starlink Growth
SpaceX’s valuation trajectory has been explosive. The per-share price of $421 in its latest secondary offering in December 2025 was nearly double the $212 a share set in July at a $400 billion valuation. The company now seeks a value of around $1.5 trillion when it hits the public market, which would surpass the prior record set by the Saudi Aramco IPO in 2019. Some reports suggest SpaceX could seek a valuation in the IPO of more than $1.75 trillion.
That puts SpaceX at somewhere between 62 and 68 times sales based on estimated 2026 revenue. According to Motley Fool, SpaceX is estimated to be doing $15 billion in annual business in 2025, and analysts at Payload Space estimate that revenue is growing at a 50% or greater pace and is likely to reach $22 billion to $24 billion in 2026. The bulk of that growth comes from Starlink, the satellite internet service that now has roughly 7,000 satellites deployed and over 8.5 million subscribers as of September 2025.
SpaceX completed a merger with Elon Musk’s AI company xAI in January 2026, combining the ventures at a roughly $1.25 trillion valuation. The deal folded X (formerly Twitter) and xAI’s Grok chatbot into SpaceX’s corporate structure, potentially explaining part of the valuation increase sought in the IPO.
Confidential Filing: Testing the Waters Without Full Exposure
The confidential IPO filing process, established under the JOBS Act of 2012 and expanded in 2017, allows any company to file their S-1/F-1 under Form DRS with the SEC confidentially, avoiding public preview. This mechanism enables SpaceX to engage privately with institutional investors, receive feedback from the SEC without public scrutiny, and retain strategic flexibility concerning timing and execution.
The confidential approach offers significant advantages. Companies might consider the confidential route in a bear market, if volatility is high, or if they wish to avoid scrutiny from the media and public. High-profile companies may choose the confidential route out of an abundance of caution, because they place a premium on privacy. SpaceX must make a public registration statement filing at least 15 days before the IPO roadshow or at least 15 days before the requested effective date of the registration statement.
Unlocking Value for Early Investors and Employees
A private placement of stock at an $800 billion valuation in December 2025 provided liquidity for employees and investors, according to Elon Musk. Thousands of SpaceX employees hold equity in various forms—RSUs, ISOs, NSOs, and ESPP shares—many of which have been illiquid for years. An IPO would provide the first true liquidity event for this workforce.
SpaceX has conducted regular secondary share sales, but access has been limited. According to CNBC, Wall Street heavy hitters have already begun throwing their weight behind SpaceX as private investors. Baron Capital’s Ron Baron said around a quarter of his personal investments are in the company, and SpaceX is one of the largest positions in the Baron Partners Fund. The IPO will allow these early backers to realize returns while enabling new institutional participation.
- SpaceX targeting March for confidential IPO filing, June for public debut
- Seeking $1.5–1.75 trillion valuation, potentially largest IPO in history
- Confidential filing allows private SEC review, flexibility on timing
- Starlink driving revenue growth, estimated at 70–80% of total sales
- Early employees and investors face complex tax and liquidity decisions
Tech IPO Market Shows Renewed Strength
The broader IPO market has shown signs of recovery after a dismal 2022–2023 period. ServiceTitan’s shares jumped more than 40% in its first day of trading in December 2024. As of late December, Astera Labs’ shares were up 277% since their March 2024 debut, San Mateo-based Rubrik’s stock price was up 110% since it hit Wall Street in April, and Reddit’s shares were up a staggering 396%.
According to Crunchbase, Nina Achadjian, a partner at Index Ventures who led the ServiceTitan investment, said investors should expect to see companies start to test the public markets in 2025 across sectors—fintech, cyber, AI, and SaaS, among others. The strong performance of 2024’s limited tech offerings has created a more receptive environment for SpaceX’s massive debut.
Competitive Pressure on Blue Origin and Boeing
A successful SpaceX IPO would intensify competitive dynamics across the space industry. Blue Origin, Jeff Bezos’ rocket company, recently achieved its first successful New Glenn orbital launch in January 2025. According to Motley Fool, Blue Origin has been actively bidding to buy United Launch Alliance for the last couple of years, and with ULA now weakened by the loss of its CEO, Blue Origin may finally get its chance to acquire its long-desired prize.
Boeing’s space division continues to struggle. Boeing is reportedly considering selling parts of its space business, following Starliner’s malfunctions and problems with its 737 Max aircraft. SpaceX’s IPO would provide the company with unprecedented capital to expand operations, potentially widening the competitive gap with struggling legacy aerospace contractors.
| Company | Status | Recent Valuation | Key Vehicle |
|---|---|---|---|
| SpaceX | Pre-IPO | $800B–$1.75T | Falcon 9, Starship |
| Blue Origin | Private | Undisclosed | New Glenn |
| Boeing (Space) | Public (parent) | ~$100B (parent) | Starliner, SLS |
| Rocket Lab | Public (SPAC) | ~$4B | Electron, Neutron |
Starlink Spin-Off Speculation Fades
For years, industry observers expected SpaceX might spin off Starlink separately. In 2020, SpaceX President Gwynne Shotwell said Starlink is the right kind of business that they can go ahead and take public, and that particular piece is an element of the business that they are likely to spin out and go public. However, that strategy appears to have been abandoned.
According to Access IPO, SpaceX, the complete company, is now stronger than ever, with both Starlink and SpaceX being strong businesses. The need to spin off a Starlink IPO no longer makes sense. As of late 2025, the company now plans to IPO as a whole, which also includes xAI. This integrated approach may reflect confidence in the combined entity’s growth trajectory and the strategic value of keeping satellite and launch operations under one roof.
What to Watch
The March filing deadline is approaching rapidly. Investors should monitor whether SpaceX meets this timeline or adjusts based on market conditions. The company’s final IPO valuation will be a critical data point—acceptance of the $1.5–1.75 trillion range would validate exceptional growth expectations, while a lower figure might signal investor caution about stretched multiples.
Regulatory review of the xAI merger could surface as a complicating factor, particularly given the opacity of financial disclosure around the combined entities. The performance of any competing mega-IPOs from OpenAI or Anthropic could also affect SpaceX’s reception, as giant listings threaten to suck up some of the cash that could be put into other deals, according to Capital Markets lawyers quoted by Yahoo Finance.
Finally, the allocation process will matter enormously. If SpaceX follows through on past commitments to prioritize retail investors and long-term Tesla shareholders, the offering could set a new precedent for employee and retail participation in mega-cap tech IPOs. Otherwise, it risks becoming another institutional lottery, with most shares locked up by the same large funds that dominated SpaceX’s private rounds.
