ANECDOTE

SpaceX Created Most Wealth Before Its IPO

  • SpaceX reached public markets at roughly $2 trillion after early investors captured most of its extraordinary growth privately.
  • Founders, employees, venture capitalists, and other private holders owned the journey from experimental rockets to a global company.
INSIGHT

  • Buying public markets no longer guarantees exposure to capitalism’s next generation of winners.
  • Companies can now become enormous privately, leaving public-market investors to buy only after much of the growth has occurred.

  • Private-market access does not automatically reproduce the returns earned by elite institutions.
  • Private-equity results are widely dispersed, so knowing Yale succeeded says little about funds available to ordinary investors.
