The reported confidential IPO filing for SpaceX represents a historic market-moving event, potentially becoming the largest IPO on record with a targeted $1.75 trillion valuation. The inclusion of Starlink's revenue growth and the xAI merger creates significant interest, though the high cash burn rate of xAI adds a layer of risk for future retail and institutional participants. The potential for rapid index inclusion and the massive capital raise suggests a major liquidity event that could significantly impact the broader market sentiment toward tech and space-related assets.

SpaceX has confidentially filed for an initial public offering with the U.S. Securities and Exchange Commission, putting Elon Musk's rocket and satellite company on track for what could be the largest stock market debut in history.
The filing was first reported by Bloomberg on April 1 and quickly confirmed by CNBC, Reuters, and the Wall Street Journal, all citing people familiar with the matter. SpaceX submitted draft registration documents to the SEC, targeting a June listing at a valuation of $1.75 trillion and a raise of up to $75 billion.
If completed near that size, the offering would surpass Saudi Aramco's $29 billion debut in 2019 as the largest IPO on record, per CNBC.
What an SEC confidential filing means
A confidential filing allows a company to submit its draft registration to the SEC for regulatory review without immediate public disclosure.
SpaceX will be required to release a public prospectus at least 15 days before its investor roadshow begins, per Via Satellite.
With a June target, the formal S-1 prospectus is expected to go public in April or early May. That document will be the first time investors see SpaceX's full financials, including Starlink's subscriber economics and the details of its xAI integration.
Starlink anchors the SpaceX valuation
The $1.75 trillion valuation is primarily anchored by Starlink, SpaceX's satellite internet business. Starlink ended 2025 with 9.2 million subscribers and more than $10 billion in revenue, Teslarati reported. By Feb. 13, 2026, the subscriber count had crossed 10 million, per Spaceflight Now, which cited SpaceX's own statement.
Analysts at Bloomberg and Quilty Space project Starlink's 2026 revenues could reach between $15.9 billion and $24 billion, per SatNews.
SpaceX's total 2025 revenue is estimated at approximately $15 billion, with profit potentially as high as $8 billion, according to The Motley Fool, citing Reuters and Payload Space.
The xAI merger complicates the picture
SpaceX completed an all-stock merger with Musk's artificial intelligence company xAI in February 2026.
The deal valued SpaceX at $1 trillion and xAI at $250 billion, creating a combined entity worth $1.25 trillion, per CNBC.

The valuation jump from $1.25 trillion at the time of the merger to the $1.75 trillion IPO target reflects expectations around the combined entity's space and AI ambitions.
But xAI has also drawn scrutiny. The company was burning roughly $1 billion a month at the time of the filing, with multiple co-founders having already departed, per Benzinga.
When SpaceX eventually lists, Musk will become the first person to helm two separate trillion-dollar publicly traded companies, CNBC noted. Tesla (TSLA) is the other.

Who is underwriting the SpaceX IPO?
Bank of America, Goldman Sachs, JPMorgan Chase, Citigroup, and Morgan Stanley are lined up as senior underwriters for the SpaceX IPO, according to Benzinga. Morgan Stanley brought back veteran dealmaker Michael Grimes as chairman of investment banking earlier this year in preparation for the offering, per Sacra.
SpaceX is also considering allocating up to 30% of shares to retail investors, roughly three times the typical Wall Street norm, per Teslarati. On a $75 billion raise, that would translate to approximately $22.5 billion worth of shares available to individual investors at IPO price.
Key facts about the SpaceX IPO filing:
- Bloomberg, CNBC, Reuters, and The Wall Street Journal confirmed the filing on April 1.
- The targeted valuation is $1.75 trillion, which would rank it above every S&P 500 company except Nvidia, Apple, Alphabet, Microsoft, and Amazon, Teslarati indicates.
- Target raise: Up to $75 billion, more than double the prior U.S. record.
- SpaceX has received over $24.4 billion from U.S. government contracts since 2008, per CNBC, citing FedScout.
- A public prospectus is expected in April or May, with a roadshow to follow.
SpaceX IPO part of a larger IPO wave
SpaceX is expected to be the first of what could be a trio of major tech IPOs in 2026. OpenAI and Anthropic are both reportedly weighing public offerings before year's end, Bloomberg reports.
Nasdaq recently issued rule changes that could allow SpaceX to join the Nasdaq 100 within 15 days of listing, which would trigger billions in forced buying from index-tracking funds, per Benzinga.
SpaceX has not confirmed any details of the filing. The SEC said it had no comment on the matter, CNN confirms. Everything disclosed publicly so far comes from unnamed sources familiar with the process.
The full picture will only become clear when the formal prospectus is filed.
