Anthropic Hits $1T on Secondary Market, Surpasses OpenAI

Key Takeaways

• Anthropic hit $1 trillion on secondary market Forge Global, surpassing OpenAI's $880 billion valuation
• The company's actual valuation from its February 2026 funding round stands at $380 billion
• One investor offered a 14-acre estate for Anthropic shares at over $800 billion valuation

Anthropic, the company behind Claude AI, has hit a $1 trillion valuation on private secondary trading marketplace Forge Global. That figure surpasses rival OpenAI's $880 billion valuation on the same platform. But before you update your mental model of the AI landscape, there's important context: these numbers don't mean what you might think.

Secondary Markets Are Not Primary Valuations

Neither Anthropic nor OpenAI trades on public stock exchanges. Most investors can't buy shares through traditional channels. Instead, early employees and existing investors sell portions of their holdings on secondary marketplaces like Forge Global.

These markets work differently from public equities. Supply is limited because few insiders want to sell. Pricing depends on individual deals, making transactions opaque. And a small group of wealthy investors controls valuations.

Anthropic's actual valuation, set during its February 2026 funding round after due diligence and structured negotiations with institutional investors, stands at $380 billion post-money. The $1 trillion figure reflects what people without access are willing to pay for a slice of the company.

Investors Are Getting Creative

The demand for Anthropic shares has reached unusual territory. According to Business Insider, Ken Sawyer, cofounder and managing partner at venture secondary firm Saints Capital, reported that an Anthropic shareholder recently offered to unload shares at a $1.15 trillion valuation.

Jesse Leimgruber, founder of OpenHome, claimed on X that a "very well-known growth fund" offered to buy Anthropic shares at a $1.05 trillion valuation. The offers keep coming. One investor posted on LinkedIn offering their 14-acre estate in exchange for Anthropic shares at a valuation of over $800 billion, more than twice the company's formal value.

“It's been an epic run for Anthropic. Everybody wants to be part of a generational opportunity in AI, and right now, Anthropic is in the pole position.”

— Glen Anderson, CEO of Rainmaker Securities

Rainmaker Securities said it had fielded numerous offers from VCs, with one coming in at a $960 billion valuation.

What's Driving the Frenzy

The gap between Anthropic's institutional valuation and secondary market pricing tells a clear story: investors without access to primary funding rounds are desperate for AI exposure. With public markets offering limited ways to invest directly in frontier AI companies, secondary markets have become the only option for many.

This dynamic creates price distortions. When supply is scarce and demand is high, buyers pay premiums that don't reflect company fundamentals. They're paying for access itself.

OpenAI Still Leads in Primary Funding

While Anthropic now leads on secondary markets, OpenAI remains the larger company by traditional measures. OpenAI has raised more capital and has a broader product portfolio including ChatGPT, DALL-E, and enterprise API services.

The secondary market valuations don't change the competitive reality. They reflect investor sentiment and market access constraints, not product superiority or revenue comparisons.

Frequently Asked Questions

What is Anthropic's actual valuation?

Anthropic's formal valuation from its February 2026 funding round is $380 billion. The $1 trillion figure comes from secondary market trading where supply is limited and pricing is opaque.

Why is Anthropic worth more than OpenAI on secondary markets?

Secondary market prices reflect what excluded investors are willing to pay for access, not company fundamentals. Limited supply of available Anthropic shares combined with high demand has pushed prices above OpenAI's secondary market valuation.

Can regular investors buy Anthropic stock?

No. Anthropic is a private company. Shares only trade on secondary marketplaces where early employees and existing investors sell their holdings. Most retail investors cannot access these platforms.

How does secondary market trading work for AI companies?

Secondary markets let early investors and employees sell shares before a company goes public. Prices are set by individual deals rather than market mechanisms, making them volatile and often disconnected from formal valuations.
