BREAKING: SpaceX Files for Historic IPO in What Could Be World's Largest Public Offering Ever

SpaceX has officially filed its S-1 registration statement with the US Securities and Exchange Commission, formally launching the process for what is expected to become the largest initial public offering in history.

The filing, confirmed on 20 May 2026, lists the proposed Nasdaq ticker as SPCX. It accelerates the path to a potential public debut in the coming weeks, with roadshows likely starting in early June.

This breakthrough comes as Starship V3 sits fully stacked on the launch pad at Starbase, Texas, with Flight 12 targeted for as early as today, 21 May 2026. The launch window opens at 6:30 p.m. EDT (5:30 p.m. local Texas time) from the new Pad 2. A successful flight would deliver powerful momentum heading straight into the IPO marketing period.

The V3 version stands approximately 124.4 metres tall, roughly 1.5 metres (5 feet) taller than V2. It brings increased propellant capacity and structural upgrades across both stages. It features the new Raptor 3 engines, which are more powerful, lighter and more efficient, along with larger grid fins on the Super Heavy booster (three instead of four, but 50 percent bigger and repositioned). Other notable changes include an integrated hot-staging ring for improved reusability and a redesigned propulsion system on the Ship upper stage.

First-quarter 2026 revenue reached $4.69 billion, driven by Starlink expansion, launch services and emerging AI-related activities. Elon Musk is expected to retain majority voting control after the offering. The company is targeting a valuation well above $2 trillion.

The IPO filing marks a defining moment for SpaceX. It will expose the company’s ambitious roadmap, massive Starlink growth, NASA Artemis support, Mars colonisation plans and reusable heavy-lift leadership to public market scrutiny and fresh capital.

Lead underwriters include Goldman Sachs, Morgan Stanley, Bank of America, Citigroup and JPMorgan Chase. The filing also reveals holdings such as 18,712 Bitcoin valued at over $1.4 billion.

With Starship already on the pad today, the stakes could not be higher. A strong performance would bolster investor confidence, while any delay or anomaly could affect sentiment as the company prepares to go public.

The global space and investment communities are watching closely. Today’s dual developments, the IPO filing and Starship countdown, underscore SpaceX’s position at the forefront of the commercial space revolution.
