Anthropic, the AI firm known for its Claude chatbot, has reached a staggering $1.2 trillion valuation on secondary markets, making it the most valuable private AI startup globally, overtaking OpenAI which is valued at $908 billion.

Significance of This Valuation

This substantial leap in valuation highlights a growing interest in AI startups and reflects the ongoing competition in the sector. The $1.2 trillion valuation marks a remarkable 550% increase from the previous year, establishing a new benchmark in private equity markets.

  • 550% year-over-year increase
  • Current valuation: $1.2 trillion
  • OpenAI valuation: $908 billion
  • Last official value for Anthropic: $965 billion in late May 2026

Market Dynamics and Trading Challenges

The demand for Anthropic's shares significantly outstrips supply, with very few current shareholders willing to divest. Glen Anderson, CEO of Rainmaker Securities, pointed out that while trades confirm the $1.2 trillion valuation, actual transactions are rare due to the lack of willing sellers.

Investors are turning to secondary markets for their trading needs since neither Anthropic nor OpenAI is publicly listed. This means that potential buyers must purchase shares from employees or early investors a process fraught with difficulty as most are reluctant to sell, even offering personal assets in trade.

Trading Mechanisms and Company Position

Special purpose vehicles (SPVs) are commonly used for transactions despite Anthropic's public disapproval of this approach. The company warns investors about the risks associated with such investments.

Many SPV transactions carry high fees, making investing more expensive for interested buyers. These dynamics complicate the trading landscape, creating barriers despite the strong interest in Anthropic's shares.

Looking Ahead: What’s Next?

As Anthropic moves forward, investors will be keen to see how this valuation holds up when public trading begins. Additionally, the competition with OpenAI may intensify, especially as the latter gains traction with new model releases. Upcoming disclosures from both companies could further affect market perceptions and valuations.
