Bessemer Venture Partners highlights Anthropic’s 80x growth in Q1

Anthropic, the company behind the Claude AI system, grew 80 times in annualized revenue and usage during the first quarter of 2026. That’s not a typo. Bessemer Venture Partners partner Byron Deeter flagged the figure as evidence of what he called a “once-in-a-generation” company.

To put that in context, the company’s own internal projections anticipated roughly 10x growth. Anthropic blew past that by a factor of eight. The result: an estimated run-rate revenue of $47 billion by mid-May 2026, a staggering leap from prior annualized figures that had been tracking around $14 billion and then $30 billion in earlier periods.

A $65 billion fundraise and a near-trillion-dollar valuation

On May 28, 2026, Anthropic closed a $65 billion Series H funding round. The post-money valuation landed at $965 billion, placing the company within striking distance of the trillion-dollar club that was, until recently, reserved for a handful of legacy tech giants.

The round attracted a who’s who of venture capital. Altimeter, Dragoneer, Greenoaks, Sequoia, and Bessemer all added to their positions. Bessemer has backed Anthropic since at least its Series D, meaning the firm has had a front-row seat to this growth curve for some time.

Anthropic now serves over 300,000 business customers. For a company founded just five years ago, that enterprise footprint is remarkable.

From OpenAI spinout to potential trillion-dollar company

Anthropic was founded in 2021 by Dario and Daniela Amodei, both former executives at OpenAI. The founding thesis centered on building AI systems with a stronger emphasis on safety and interpretability.

The growth trajectory tells a clear story. Revenue climbed from an estimated $14 billion annualized to $30 billion, then surged to $47 billion in run-rate by mid-May. Each milestone arrived faster than the last, compressing what would normally be years of scaling into months.
