SpaceX filed its S-1 with the SEC on May 20, 2026, targeting roughly $75 billion at a valuation between $1.75 trillion and more than $2 trillion. Class A shares will list on Nasdaq and Nasdaq Texas under SPCX, with Goldman Sachs, Morgan Stanley, and Bank of America leading the syndicate. The filing is the largest public offering in market history, and the document itself reads less like a prospectus than a consolidation of Elon Musk’s holdings into a single instrument retail can buy.

The books now contain three businesses fused by related-party housekeeping. X.AI Holdings was acquired by SpaceX effective February 2, 2026; X Holdings was acquired by xAI effective March 28, 2025, both treated as transactions between entities under common control. Consolidated Q1 2026 revenue is $4.69 billion against a $1.94 billion operating loss. Accumulated deficit through March 2026: $41.3 billion.

The segments diverge sharply. Per Fortune, Starlink generated $4.4 billion in operating profit in 2025, while the Space segment posted a $657 million operating loss on $4.086 billion of revenue. xAI lost $6.4 billion in 2025 and burned another $2.5 billion in Q1 2026. The plug for that hole is unusual: a Cloud Services Agreement under which Anthropic pays $1.25 billion per month for capacity on the COLOSSUS and COLOSSUS II clusters through May 2029, potentially worth over $40 billion. It’s also 90-day-cancellable.

Then there’s the governance. Class B shares carry 10 votes to Class A’s one, leaving Musk with 85.1% of combined voting power post-IPO as CEO, CTO, and chairman. SpaceX qualifies as a controlled company and is opting out of Nasdaq’s independent board requirements. TechCrunch notes Musk would be awarded up to a billion additional super-voting shares once a million people are living on Mars.

The S-1 claims a $28.5 trillion total addressable market ($26.5 trillion AI, $1.6 trillion connectivity, $370 billion space), described by Fortune as “the largest actionable TAM in human history.” Retail gets 30% of the offering, roughly $22.5 billion, about three times the norm for a mega-IPO. The roadshow starts in early June, with Starship targeting payload delivery in the second half of 2026 and orbital AI compute satellites pencilled in for 2028.

The 2014 Alibaba listing raised $25 billion and was the previous benchmark for governance-by-founder. This one triples it and reframes the question. Public-market discipline, in the SPCX structure, is the price retail pays for a ticket.
