#AnthropicSecondaryValuationHits1.2Trillion – Overtaking OpenAI in a Historic Market Frenzy

In a milestone that defies traditional market logic, Anthropic – the creator of the Claude AI assistant – has seen its secondary market valuation soar to an astounding **$1.2 trillion**. This represents a **550% year-over-year increase** and places the company firmly ahead of its chief rival OpenAI, which currently trades at around $908 billion on the same platforms.

The Valuation Journey

Just three months ago, Anthropic's secondary market valuation stood at $1 trillion. The company's most recent primary funding round – a Series H completed in late May 2026 – officially valued the company at $965 billion. The current $1.2 trillion secondary pricing represents a significant premium over that official figure. To put this in perspective, just over a year ago, Anthropic's secondary market pricing was roughly one-sixth of today's level.

The Scarcity Paradox

What makes this valuation particularly remarkable is that almost no one is actually selling. Secondary markets function only when employees or early investors are willing to part with their shares – and right now, they are not.

Javier Avalos, CEO of the secondary trading platform Caplight, described Anthropic as "the most sought-after company the venture secondary market has ever seen". Glen Anderson, CEO of Rainmaker Securities, put it even more bluntly: "The demand outstrips the supply in Anthropic so much that it's rare to get a trade done because no one's selling".

This extreme scarcity has driven some prospective buyers to extraordinary lengths – including offering to exchange their homes for Anthropic stock.

The SPV Controversy

Most trades that do occur are structured through Special Purpose Vehicles (SPVs), which pool money from multiple buyers into a single deal. However, Anthropic has publicly disavowed these arrangements. The company's website explicitly warns: "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".

Despite this warning – and the substantial fees that often accompany SPV deals – buyers continue piling in, desperate not to miss what they see as the AI gold rush.

The OpenAI Comparison

Anthropic's $1.2 trillion valuation now comfortably exceeds OpenAI's $908 billion secondary market valuation. The gap in investor interest is stark: for every two buyers seeking OpenAI shares, there are approximately five pursuing Anthropic.

OpenAI has recently seen renewed interest following the release of its GPT-5.6 model series, including the flagship "Sol" model. However, Anthropic continues to dominate investor attention.

What This Really Means

It is crucial to understand that secondary pricing reflects illiquid, minority stakes with no board seats and no guaranteed exit. Matt Murphy of Menlo Ventures, an early Anthropic backer, calls secondary valuations a "noisy signal" – though he concedes the company's revenue has run "crazy above" its own plan.

The IPO Catalyst

Anthropic confidentially filed for an IPO with the SEC in June 2026. Bankers are already discussing a potential late-2026 listing that could value the company well above $900 billion, with Goldman Sachs, JPMorgan, and Morgan Stanley reportedly providing advisory services.

When the company goes public, the scarcity that has driven this $1.2 trillion figure will vanish. A public market floods the system with shares, and the valuation will finally meet buyers who can walk away. **The real test is whether $1.2 trillion holds up against an open market rather than a handful of desperate buyers**.

For now, Anthropic sits atop the private AI world – a $1.2 trillion company built on extreme demand, near-zero supply, and investor FOMO that has reached fever pitch.
