Anthropic PBC raised $65 billion [1] in a Series H funding round on May 28, 2026, becoming the most valuable private AI firm.
This valuation shift marks a pivotal moment in the artificial intelligence race, as Anthropic leapfrogs OpenAI to claim the top spot in market capitalization for private AI companies.
The funding round pushed the Silicon Valley-based company to a post-money valuation of approximately $965 billion [1]. Other reports place the valuation at $900 billion [4], though most industry trackers align with the higher figure as the company nears the $1 trillion mark.
Led by CEO Dario Amodei, Anthropic intends to use the capital to fund the rapid expansion of its compute and cloud partnerships [5]. The investment follows a three-month surge in revenue, with the company reporting an annualized revenue of $47 billion [3].
The Series H round reflects growing investor confidence in Anthropic's ability to scale its infrastructure and compete with other major AI labs. The company is positioning itself to capitalize on the increasing demand for large-scale language models, a move that requires massive capital for hardware and energy.
By securing this level of funding, Anthropic ensures it has the liquidity to maintain its development pace without relying on smaller, incremental rounds. The company's growth trajectory suggests a shift in the competitive landscape where compute capacity is as critical as algorithmic breakthroughs.

The shift in valuation suggests that investors are now pricing Anthropic's scaling strategy and revenue growth as more sustainable or aggressive than OpenAI's. By nearing a $1 trillion valuation, Anthropic is no longer just a challenger but a dominant financial force, signaling that the AI sector is moving from a phase of pure research into a high-capital industrial phase where infrastructure ownership determines market leadership.
