As SpaceX goes public, a $100 billion shadow market faces a reckoning

A day ahead of the spectacle of Space X’s IPO, the much-anticipated trillion-plus valuation of the company—a Frankensteined creature of Elon Musk’s dreams and realities—is emerging as an investor Rorschach test. Some will see cosmic potential, while others will see science-fiction red flags.

These transactions have happened in the dark for years, with accelerating velocity through the AI boom. But this summer of white-hot IPOs—SpaceX, OpenAI, and Anthropic—could be the crucial moment where the lights flicker on.

The average venture-backed unicorn now remains private for ten years at minimum, and there are about half as many public companies today as there were in 1996. It has both gotten easier to stay private as more capital from VCs and other investors has become available, and being public—with the scrutiny that entails—is increasingly seen as cumbersome.
