Key Points

  • The secondary market for private shares is described as unusually active, with Anthropic positioned as the most actively traded name.
  • The article suggests a shift in investor attention, noting that OpenAI is “losing ground” relative to Anthropic in private-market trading.
  • A potential SpaceX IPO is framed as a looming event that could materially change liquidity, valuation expectations, and capital allocation across private-tech markets.
  • The overall takeaway is that private-market momentum right now is being driven by competitive positioning among leading AI companies and by high-profile upcoming events like SpaceX’s possible listing.
Glen Anderson, president of Rainmaker Securities, says the secondary market for private shares has never been more active — with Anthropic the hottest trade around, OpenAI losing ground, and SpaceX's looming IPO poised to reshape the landscape for everyone.
