AI BriefingAnthropic Surpasses OpenAI to Break $1 Trillion Valuation
Key point
Anthropic has overtaken OpenAI with a $1 trillion valuation based on secondary market trading.
Details
Anthropic has recorded a $1 trillion valuation based on secondary market trading, surpassing its key rival OpenAI. On the trading platform Forge Global, Anthropic was valued at $1 trillion, while OpenAI was valued at approximately $880 billion.
Anthropic's valuation in its most recent funding round was $380 billion three months ago, while OpenAI's was about $852 billion based on its latest round. This surge appears to reflect a shortage of shares in circulation and strong investor buying demand more than actual fundraising.
The rise in valuation has been influenced by the rapid spread of Claude Code and partnerships with companies like Amazon and Palantir. The company's annualized revenue jumped from $9 billion at the end of 2025 to $39 billion in March 2026, and some investors reportedly were even offered real estate in exchange for securing a stake in Anthropic.
