Anthropic Secures $30 Billion, Reaches $900 Billion Valuation

The arms race in artificial intelligence has just reached a new and staggering financial milestone. Anthropic, the creator of the Claude model, has signed a term sheet to raise $30 billion in a new funding round. The deal values the company at an astronomical $900 billion (pre-money), placing it ahead of its main rival, OpenAI.

Insane Growth: 3x in 3 Months

What's most shocking to the traditional market is not just the volume of capital but the speed of valuation increase. In February 2026, the company had already surprised Wall Street with a Series G valuing the company at $380 billion. Just three months later, the valuation nearly tripled. To put this explosion into context, in March 2025, the company was worth about $61.5 billion.

With these new figures, Anthropic comfortably surpasses the last known valuation of OpenAI, which hovered around $852 billion, temporarily becoming the most valuable private startup on the planet.

The Revenue Engine: Enterprise and Compute

Behind this venture capital frenzy are the real revenue numbers. Anthropic's ARR (Annual Recurring Revenue) jumped from $9 billion at the end of 2025 to an impressive $40 to $45 billion by May 2026. This leap is directly driven by the massive success of products focused on code and automation, with over 1,000 corporate clients (Enterprise) paying contracts exceeding $1 million annually.

The round is co-led by heavyweights like Greenoaks, Sequoia Capital, Altimeter Capital, and Dragoneer, with expected contributions of over $2 billion each. Amazon and Google also remain major partners and strategic shareholders.

The GPU War and Potential IPO

Industry experts and analysts point out that the primary motivation for raising $30 billion is purely infrastructural. The capital will be used almost entirely to secure computational power (GPUs) and energy contracts, allowing for the training of models that require unprecedented scales.

Although the signed term sheet represents a high degree of confidence for closing later this month, the round signals a phase change. Many early-stage investors have opted not to participate in this capital injection, awaiting a likely IPO later in 2026. The $900 billion round is seen by the market as potentially the last major private funding before Anthropic goes public.
