What to Know
- SpaceX’s official IPO filing sets up a likely Nasdaq debut next month.
- Goldman Sachs is lead left on the prospectus, followed by Morgan Stanley, Bank of America, Citigroup and JPMorgan Chase.
- SpaceX was valued at $1.25 trillion in February after merging with xAI, Elon Musk’s artificial intelligence startup, meaning new investors will be buying in at a historically high price.
- The IPO is likely to be the first of three potential mega offerings this year, with OpenAI and Anthropic both eyeing the public market.
- Follow-up filings from SpaceX will lay out the expected per-share pricing range and likely more detail on the top shareholders.
Elon Musk’s SpaceX is officially headed for the public market in what’s likely to be a record IPO that will put the world’s richest person at the helm of two separate trillion-dollar publicly traded companies.
In a prospectus with the Securities and Exchange Commission on Wednesday, SpaceX said it plans to list under ticker symbol SPCX on the Nasdaq. SpaceX confidentially filed with the SEC in April, and CNBC reported last week that the company is aiming to kick off a roadshow to market the deal on June 8.
Founded by Musk in 2002 to develop and operate reusable rockets, SpaceX has turned into NASA’s biggest launch partner after the agency ended its space shuttle program in 2011. In addition to its massive aerospace and defense contracts, SpaceX also operates the Starlink satellite internet service and a constellation of around 10,000 satellites, as well as artificial intelligence unit xAI, which previously acquired X, the social network formerly known as Twitter.
CNBC’s reporters are covering SpaceX’s IPO from bureaus in San Francisco and Englewood Cliffs, New Jersey.
SpaceX sees $28.5 trillion addressable market
SpaceX sees a total addressable market of $28.5 trillion, and said in its prospectus that identifying and creating trillion-dollar market opportunities is one element of its “repeatable business model.”
The vast majority of its addressable market is outside of SpaceX’s existing businesses. There’s an $870 billion market for Starlink’s broadband business, a $740 billion market for Starlink’s mobile unit, a $600 billion digital advertising market for X to pursue and a $2.4 trillion AI infrastructure market.
Then there’s enterprise applications, a $22.7 trillion market, based on an estimate from the Digital Cooperation Organization.
“We believe we are still in the early days of AI transforming enterprises, with AI-powered enterprise applications poised to reshape the digital economy,” SpaceX said. The company said that with help from Tesla, it’s developing an AI agent service called Macrohard that’s meant to emulate digital work and create an AI-run software company.
X advertising revenue declined in Q1 during technology rebuild
Advertising revenue from X, formerly known as Twitter, declined by $100 million in the first quarter, as the business dealt with the overhaul of its ad technology. Musk bought Twitter in 2022, renamed it X and then merged it with xAI, now part of SpaceX.
The advertising figures are a stark contrast to results from Meta, Pinterest and Reddit, which all recorded sales growth.
For the full year in 2025, ad revenue grew by $115 million after plummeting by $595 million in 2024, according to Wednesday’s prospectus. Data licensing revenue has consistently grown.
Meanwhile, X has been working to sign up more paying subscribers. Between X and xAI’s Grok assistant, subscription revenue increased by $365 million in 2025 and another $177 million in the first quarter of 2026.
X started to release its new Ads Manager in April. SpaceX says it expects to boost advertising revenue per user and bring in more advertisers.
