Elon Musk’s SpaceX has taken a major step toward going public, confidentially submitting paperwork for an initial public offering that could rank among the largest equity debuts ever and potentially reshape investor appetite for high-growth technology names.
According to reporting from The Wall Street Journal, Reuters, and Bloomberg, the aerospace and satellite company has filed with US regulators in a move that allows it to test the waters privately before revealing detailed financials.
If completed at the upper end of expectations, the offering could eclipse the $25.6 billion IPO of Saudi Aramco, currently the largest in history. It would inevitably fuel further demand for space ETFs which are already taking off with significant thrust.
People familiar with the plans told The Wall Street Journal that the deal could raise between $40 billion and $80 billion, highlighting the scale of investor demand anticipated for the offering.
The IPO follows SpaceX’s recent integration with Musk’s artificial intelligence venture, xAI, a move that has expanded the company’s scope beyond rockets and satellite connectivity into AI infrastructure.
The combined entity was valued at roughly $1.25 trillion earlier this year and positions SpaceX at the intersection of space technology and AI with ambitions that include orbital data centers and expanded satellite networks.
Starlink, the company’s satellite internet business, remains a central revenue driver, with millions of subscribers globally and growing ties to defense and government contracts including the Starship Human Landing System which is the vehicle that will be tasked with landing astronauts on the Moon during future Artemis III missions. The firm is not involved in this week’s Artemis II launch.
While a public debut could come as early as mid-2026, the timeline remains fluid, as companies that file confidentially can delay or adjust plans based on market conditions and regulatory feedback.
Still, the move comes as Wall Street braces for a resurgence in large-scale IPOs, with SpaceX expected to lead a wave that could include other high-profile technology firms such as OpenAI and Anthropic.
Analysts say the listing could inject fresh momentum into equity markets that have seen uneven activity in recent years, while also drawing heightened scrutiny to Musk’s broader business ecosystem.
SpaceX’s transition from private to public markets marks a pivotal shift for one of the world’s most valuable privately held companies, long seen as emblematic of Silicon Valley’s ability to scale outside traditional capital markets.
The company’s IPO could not only redefine valuations in the space and AI sectors but also test investor appetite for mega-cap growth stories at a time of evolving macroeconomic and geopolitical risks.
If successful, the offering would cement SpaceX’s position as a cornerstone of the next generation of public tech giants, while potentially opening the door for a new era of trillion-dollar IPOs.
