- Anthropic has reached a $1 trillion implied valuation on secondary markets, surpassing OpenAI on the same measure, according to Business Insider reporting from April 2026.
- The figure represents more than a 16-fold increase over Anthropic’s last disclosed primary-round valuation of approximately $61.5 billion, set in early 2025.
- Secondary market prices reflect bilateral share trades by existing holders and carry no formal due-diligence verification, making them distinct from primary funding round valuations.
- The shift marks a notable reversal: OpenAI, which raised at a reported $157 billion valuation in a SoftBank-led round in late 2024, had previously held the higher secondary market price among private AI labs.
What Happened
Anthropic, the AI safety company led by CEO Dario Amodei and President Daniela Amodei, has hit a $1 trillion implied valuation on secondary markets — surpassing OpenAI on that measure — according to Business Insider, published April 23, 2026. The report places Anthropic ahead of OpenAI in at least one private-market pricing metric, a shift from recent history in which OpenAI had commanded higher implied prices in pre-IPO trading.
Why It Matters
The $1 trillion secondary figure arrives roughly a year after Anthropic’s last disclosed primary round. In early 2025, the company closed a financing that valued it at approximately $61.5 billion post-money — a number that already reflected substantial growth from its 2023 valuation of around $18 billion following strategic investments from Amazon and Google. A trillion-dollar secondary price implies the market is pricing in a trajectory that has substantially outpaced those earlier benchmarks.
OpenAI, by contrast, raised at a reported $157 billion valuation in a SoftBank-led primary round in late 2024, and was reportedly in discussions for subsequent rounds at even higher figures. That Anthropic has now overtaken it on secondary markets reflects a reallocation of investor sentiment, though secondary prices are not anchored to audited financials or formal term sheets.
Technical Details
Secondary market transactions involve existing shareholders — typically employees or early-stage investors — selling equity to institutional or accredited buyers on platforms such as Forge Global, Nasdaq Private Market, or through direct bilateral agreements. Unlike primary rounds, these transactions are not subject to the same disclosure requirements and do not involve new capital entering the company. Prices in this market can diverge substantially from the most recent primary-round valuation and are sensitive to scarcity of available shares.
Anthropic’s revenue base spans its Claude API for developers, enterprise contracts, and direct consumer subscriptions. Amazon committed up to $4 billion in investment beginning in 2023, with Google holding a separate strategic stake — structural relationships that provide both capital and cloud distribution, and that likely contribute to upward pressure on secondary demand. The degree to which secondary buyers are pricing in specific revenue or ARR figures was not disclosed in Business Insider’s reporting.
Who’s Affected
Anthropic employees holding vested equity stand to benefit most directly if secondary prices are sustained through a liquidity event. Institutional funds that have accumulated secondary Anthropic positions — including dedicated pre-IPO vehicles that have grown in prominence as AI lab IPO timelines remain uncertain — now hold assets marked at the trillion-dollar threshold. For OpenAI, the development introduces a competitive dimension beyond model benchmarks: investor narrative.
What’s Next
Neither Anthropic nor OpenAI had announced a firm IPO timeline as of April 2026. A sustained $1 trillion secondary valuation would place Anthropic among the largest pre-IPO implied capitalizations in the history of the technology sector — above the pre-IPO peak valuations of companies including Uber and Airbnb. Whether public market investors would assign comparable multiples upon listing depends on revenue disclosure, growth rates, and the competitive environment at the time of any offering, none of which Anthropic has made public.
