Anthropic is considering a $50 billion funding round at a valuation between $850 billion and $900 billion, potentially surpassing OpenAI as the world's most valuable AI startup. Meanwhile, secondary market trading platforms are pricing the Claude AI maker at $1 trillion, driven by explosive revenue growth and intense investor demand for exposure to artificial intelligence.

Anthropic Weighs Massive Funding Round at $900 Billion Valuation

Anthropic, the maker of Claude AI, has received multiple preemptive offers to raise fresh capital of around $50 billion at a valuation in the $850 billion to $900 billion range, according to multiple sources

The round is expected to total $40 billion to $50 billion, though investor demand appears to be much higher given the company's rapid growth

. One institutional investor prepared to commit as much as $5 billion has yet to secure a meeting with Anthropic CFO Krishna Rao, highlighting the feverish investor interest surrounding the private funding round. If Anthropic proceeds with the fundraise at these terms, it will more than double its February valuation of $380 billion and potentially match or surpass OpenAI, which closed a $122 billion round at an $852 billion post-money valuation

Revenue Acceleration Drives Explosive Growth

The Anthropic valuation surge is anchored in extraordinary financial performance. The company announced this month that its annual revenue run rate has surpassed $30 billion, a dramatic increase from roughly $9 billion at the end of 2025

A large portion of that revenue acceleration is driven by Anthropic's artificial intelligence coding capabilities, specifically through Claude Code and Cowork platforms

Secondary Market Valuation Reaches $1 Trillion

While primary fundraising discussions continue, Anthropic's secondary market valuation has surged to approximately $1 trillion on private trading platforms like Forge Global, surpassing competitor OpenAI's $880 billion valuation in the same markets

. Kelly Rodriques, CEO of Forge Global, confirmed the implied valuation was "hovering around the $1 trillion mark"

The secondary markets behave very differently from public equities, with limited supply as few insiders are willing to sell, pricing based on individual deals, and valuations controlled by a small handful of powerful investors

. Glen Anderson, CEO of Rainmaker Securities, told Business Insider he had been offered the opportunity to buy Anthropic shares at a valuation of $960 billion, a price that would have been "unthinkable" even weeks ago

Surpassing OpenAI in Market Sentiment

The contrast between Anthropic and OpenAI in secondary markets is striking. While Anthropic's secondary market valuation represents more than 2.5 times its February primary valuation, OpenAI trades at just 3% above its $852 billion primary valuation

. According to Caplight, an analytics platform tracking private-market share activity, the ratio of sellers to buyers in OpenAI shares was five-to-one in Q1 2026, with interest described as "tepid" and bids often below the company's last primary valuation

Founded in 2021 by Dario and Daniela Amodei, former OpenAI executives, Anthropic has developed a series of AI tools aimed at overhauling how businesses handle tasks from coding to cybersecurity . In early April, the company unveiled a new model called Mythos that can detect and exploit vulnerabilities in critical software, though it deemed the model too dangerous for wide release .

Strategic Backing and IPO Prospects

Google recently committed to invest $10 billion in Anthropic at a $350 billion valuation, with plans to invest up to another $30 billion if the AI startup hits certain performance targets . Amazon.com Inc. is also investing $5 billion at the same valuation, with plans to inject $20 billion more over time, though it's unclear whether these firms will participate in the upcoming funding round.

Anthropic is reportedly exploring an IPO as early as October 2026, which could provide liquidity for investors clamoring to get exposure to the company . The company has been on the hunt for more infrastructure to meet growing demand for its products, and the new capital would support this expansion as it contends with OpenAI for dominance in the generative AI sector.
