SpaceX files S-1, joins OpenAI and Anthropic in the 2026 IPO queue

SpaceX submitted its S-1 registration statement to the SEC, officially entering the IPO pipeline alongside OpenAI and Anthropic. The three deals are now expected to define the 2026 and 2027 public-market calendar for venture-backed technology companies.

The SpaceX filing disclosed a digital asset treasury position that exceeded prior market forecasts, according to FinanceFeeds. The size and composition of that position had not been publicly confirmed before the registration document went live. The disclosure adds a balance-sheet dimension to a company previously valued on launch cadence and Starlink subscriber growth.

CNBC framed the trio as the marquee names in a narrow window for late-stage venture exits. The IPO market has been functionally closed to most venture-backed companies since mid-2022, and these three represent the tier that can re-open it. OpenAI and Anthropic carry the AI infrastructure narrative; SpaceX carries both the space economy and now a crypto treasury angle.

The timing matters. If any of the three files and prices successfully in 2026, the comps reset and the IPO window widens for the rest of the venture stack. If any stumbles on valuation or allocation, the window stays narrow and the venture overhang compounds. The market will re-rate venture liquidity expectations around whichever company prices first.
