OpenAI Secondary Demand Cools as Buyers Chase Anthropic

Relative Value Is Starting to Matter in AI Secondaries Bloomberg reports that institutional holders have recently tried to sell roughly $600 million of OpenAI shares through secondary channels, with limited buyer interest. The shift is notable because it follows OpenAI’s blockbuster financing at an $852 billion post-money valuation, a level that cements the company’s scale but also narrows perceived near-term upside for new secondary buyers. At the same time, investors are said to be aggressively pursuing Anthropic exposure, betting that its valuation has more room to catch up as enterprise adoption and revenue scale improve. In other words, AI secondaries are becoming more price-sensitive: buyers still want frontier-model exposure, but they increasingly care about entry point, liquidity optionality, and comparative upside. Signals from the Secondary Tape Institutional sellers are seeking liquidity despite OpenAI’s headline financing success Buyers appear more willing to underwrite Anthropic at lower relative valuation levels Secondary demand is fragmenting by perceived upside rather than prestige alone Bloomberg said OpenAI shares had, in some cases, become nearly impossible to unload while demand for Anthropic stock reached record levels across trading platforms. Why This Matters for Private Markets This is a useful reminder that primary-round headlines do not automatically translate into secondary-market clearing power. For investors in AI unicorns, the key question is now less about whether demand exists and more about which cap tables still offer compelling entry. That dynamic should widen the spread between top-tier names with obvious upside catalysts and mega-valued issuers where incremental appreciation is harder to underwrite.
