Anthropic's secondary-market valuation hits $1.2 trillion, up 550% in a year

On July 12, 2026, secondary markets valued Anthropic at $1.2 trillion, according to Business Insider. That is a 550% increase in a single year, a record jump for a company that has also become one of the most expensive and least accessible private companies in the world for investors.

Why Anthropic shares are out of reach

From the start, Anthropic has strictly limited access to its shares, a strategic decision by its founders. Large blocks were distributed among the founders, Dario and Daniela Amodei (named "Abodefi" in the source), leading venture investors (Sequoia Capital, Google, Saudi Arabia's Public Investment Fund) and individual employees. Only a small fraction of the total trades on open secondary markets: leftovers from rare negotiations between institutional investors who do not want to part with such a scarce and promising asset.

The economics of secondary markets are simple. Every rare deal becomes an event and a signal to the rest of the market. If two large funds agree to buy a small block at a price implying a $1.2 trillion valuation, other participants extrapolate that price to the entire company. The result is extreme price volatility on minimal trading volume, a classic trait of a speculative bubble, where price loses its link to real liquidity.

What sustains investor demand

Behind the demand for Anthropic shares are real achievements in AI development. In 2026, Anthropic released a series of competitive Claude models, including the high-performing Claude Opus 4.6, attracted strategic investments of tens of billions of dollars from Google and Saudi Arabia, and deployed its commercial service in hundreds of enterprise projects worldwide.

Investors see the company's potential. The key factors supporting demand for the shares:

• Claude Opus 4.6, Claude Sonnet and other versions are used by developers and enterprise customers in production environments
• Google has invested tens of billions of dollars in Anthropic as part of a deep strategic partnership
• Enterprise customers increasingly choose Anthropic as a serious competitive alternative to OpenAI in a fast-growing market
• The scarce supply of shares on secondary markets artificially creates hype and speculative demand

Demand is real, but supply is cryptically limited.

What this means for AI investing

The $1.2 trillion valuation reflects two opposing but equally true processes. First: Anthropic really is a powerful, ambitious AI lab that competes at the level of OpenAI, Google DeepMind, xAI and other recognized industry leaders, and its business is growing fast. Second: the secondary market systematically overvalues the company because of a critical shortage of freely floating shares.

The gap between a notional fair value (which the market will set at an IPO) and the current speculative valuation will inevitably narrow over the next several years. That will happen either through an initial public offering (IPO) and a listing on the public stock market, if Anthropic decides to raise additional capital that way, or through a gradual widening of share access to a broader group of investors. For now, secondary-market prices are pure speculation on scarcity and lack of information, not an honest reflection of the company's real value.
