Anthropic Runs Hot While OpenAI Shares Go Cold

What happened: A secondary-market broker told TechCrunch demand for Anthropic shares is intense — “no sellers” — while investors trying to offload roughly $600M of OpenAI shares are reportedly struggling to find takers. The private market, it seems, has discovered the concept of preferences.

Why it matters: Secondary markets are turning into a faster “AI sentiment index” than press releases and headline valuations. If OpenAI can raise at $852B in a primary round while secondaries price it closer to $765B, that gap is a live signal about liquidity, narrative control, and investor confidence.

Wider context: The piece connects the shift to Anthropic’s highly public standoff with the US Department of Defense, which the broker says rallied attention around Anthropic as a differentiated “hero” brand. Meanwhile, SpaceX’s looming IPO could soak up IPO liquidity, making timing riskier for anyone else eyeing the public markets.

Background: TechCrunch cites Bloomberg reporting that buyers indicated they had $2B ready for Anthropic exposure, while OpenAI warned investors to be cautious about unauthorized access via SPVs. Banks reportedly began offering OpenAI shares without carry fees, while charging typical carry for Anthropic access.


Singularity Soup Take: The AI race isn’t just models — it’s liquidity, story, and who gets to look inevitable on a spreadsheet. When secondaries go “eh, maybe,” it’s the closest thing we have to an honesty filter in a market built on vibes and term sheets.

Key Takeaways:

  • Secondary Sentiment Split: A broker describes Anthropic as the hardest private stock to source due to strong demand and scarce sellers, while OpenAI shares face softer demand on secondary markets despite a higher headline valuation.
  • Valuation Gap Signal: The article notes secondary pricing for OpenAI around $765B versus a reported $852B primary-round valuation, highlighting how liquidity and buyer appetite can diverge from “official” numbers.
  • IPO Liquidity Squeeze: With SpaceX reportedly moving toward a mega-IPO, the broker argues public-market capital could be absorbed, raising the stakes for AI companies considering their own IPO timing in the same window.
