Private markets are doing what they do best: turning governance vibes and compute commitments into price signals.
Secondary-market demand is running hot for Anthropic shares while OpenAI shares are reportedly offered at a discount, as Anthropic also expands long-term compute capacity with Google and Broadcom.
The headline: secondaries as a faster truth serum than press releases
In the latest installment of “markets have feelings,” TechCrunch reports on what Bloomberg framed earlier in the week: secondary-market buyers are ravenous for Anthropic shares and noticeably cooler on OpenAI, with indications that OpenAI stock is being offered at a discount to its most recent primary valuation.
Glen Anderson of Rainmaker Securities told TechCrunch that Anthropic is the hardest stock to source on his marketplace because “there’s just no sellers.” Bloomberg quoted Next Round Capital’s Ken Smythe saying buyers had indicated roughly $2 billion for Anthropic, while around $600 million of OpenAI shares for sale hadn’t found takers. Whether you treat this as gospel or as “finance guys telling stories,” the direction of the signal is consistent.
Why it matters: governance, narrative, and the cost of being the default
Secondary markets aren’t just pricing revenue, they’re pricing optionalities, who gets to be the “safe” bet, who is facing transfer friction, and who looks like they might be forced into weird structures to keep the valuation story intact.
OpenAI, per Bloomberg, has tried to clamp down on high-fee secondary access and steer trading through “authorized channels.” That is understandable and rational, and also a tell: the closer you police access, the more the market wonders what you are trying to prevent. Anthropic, meanwhile, benefits from a “scarcity” narrative: high demand, low supply, heroic procurement standoff vibes (the Pentagon saga), and the perception of room to run.
Compute as credibility: the 2027 capacity bet
One reason this matters beyond investor gossip is that Anthropic is also making long-horizon infrastructure commitments. TechCrunch reports Anthropic has a new agreement with Google and Broadcom to expand TPU capacity, with new compute coming online in 2027. The story cites a Broadcom SEC filing indicating the deal includes 3.5 gigawatts of compute, and notes the arrangement extends earlier plans and ties into Anthropic’s stated U.S. compute infrastructure commitments.
Finance and infra are now the same story: if you can credibly secure future compute, you can credibly promise future capability and revenue. If you can’t, you will eventually discover that your model roadmap is actually a supply-chain roadmap wearing a hoodie.
A quick stakes map: who wins, who loses
- Anthropic: wins narrative momentum and can use scarcity to keep terms favorable, but risks becoming a victim of its own demand if delivery lags.
- OpenAI: still huge, but the “discount” framing is a tax on being the default. Control fights in secondaries can amplify distrust if handled clumsily.
- Big cloud suppliers (Google/Broadcom): win either way. Selling compute is the purest business model in this entire ecosystem.
- Employees and early shareholders: win when liquidity exists, lose when narratives turn into transfer restrictions and “authorized channels.”
What to Watch
Clearing events: whether OpenAI secondaries actually clear at a persistent discount, or if demand returns once supply tightens.
Compute delivery: details that emerge about where the TPU capacity lands, and what portion is genuinely incremental vs. re-allocated.
