The artificial intelligence firm Anthropic, creator of the Claude conversational AI assistant, has achieved a $1.2 trillion valuation in secondary market trading. This positions the company as the world’s highest-valued private AI enterprise, eclipsing competitor OpenAI.
This $1.2 trillion assessment marks a remarkable 550% climb compared to the previous year, per Javier Avalos, who cofounded and leads Caplight, a platform facilitating private secondary transactions.
Avalos characterized Anthropic as “the most sought-after company the venture secondary market has ever seen.”
Limited Share Availability Constrains Transaction Volume
While investor appetite remains robust, finalized deals remain infrequent. Glen Anderson, who serves as CEO of Rainmaker Securities, verified that negotiations occur at the $1.2 trillion price point, though successful closures happen rarely.
“The demand outstrips the supply in Anthropic so much that it’s rare to get a trade done because no one’s selling,” Anderson told Business Insider.
Since neither Anthropic nor OpenAI trades on public exchanges, interested parties must acquire ownership through secondary channels. This requires purchasing positions from current employees or initial backers willing to liquidate holdings — a group that remains extremely small.
Certain potential investors have pursued extraordinary tactics to secure access, including proposing real estate exchanges for Anthropic equity.
Special Purpose Vehicles Dominate Despite Corporate Resistance
The majority of completed transactions utilize special purpose vehicles, commonly called SPVs. These structures consolidate funds from numerous investors into one unified purchase.
Anthropic has openly resisted this approach. The company’s official website declares: “Invest at your own risk: if someone offers you a way to participate, even on an indirect basis, in an investment in Anthropic, assume that it is invalid.”
Avalos additionally observed that numerous SPV arrangements impose substantial fees on participating investors.
Anthropic’s most recent formal capital raise, a Series H concluded in late May 2026, established a $965 billion company valuation. The current secondary market pricing of $1.2 trillion represents a significant premium above that benchmark.
OpenAI, which maintained valuation superiority over Anthropic for an extended period, currently trades at $908 billion on Caplight’s platform.
The valuation disparity between these AI leaders also appears in their latest primary funding events. OpenAI secured an $852 billion valuation following its March 2026 financing round, while Anthropic’s Series H reached $965 billion.
Investor enthusiasm for OpenAI had experienced a lull until recent developments. The launch of its GPT-5.6 model family, featuring the premium “Sol” system and economical “Terra” option, has reignited purchasing interest, Anderson reported.
Regarding comparative demand levels, Avalos estimated approximately five investors pursuing Anthropic positions for every two examining OpenAI opportunities.
Anthropic submitted a confidential initial public offering registration document to the Securities and Exchange Commission during early June 2026. Company representatives indicated that final timing for any market debut will hinge on prevailing financial conditions.
