Summary
Anthropic announced a landmark $65 billion funding round at a $965 billion valuation, becoming the world's most valuable AI startup and surpassing OpenAI's $852 billion valuation. The massive raise more than doubled the net worth of each of Anthropic's seven cofounders—Dario and Daniela Amodei, Jack Clark, Sam McCandlish, Chris Olah, Tom Brown, and Jared Kaplan—to approximately $16.6 billion apiece, based on their estimated 1.7% individual stakes in the company.
The valuation has skyrocketed dramatically, rising from $380 billion just four months ago and more than 15-fold from $61.5 billion a year ago, reflecting the intense investor appetite for frontier AI startups. The cofounders' individual fortunes now exceed those of many AI executives at competing firms; while OpenAI president Greg Brockman's stake is valued higher at nearly $30 billion, the Anthropic founders significantly outpace OpenAI CEO Sam Altman, who holds no direct equity stake despite a reported $3.5 billion net worth from other investments.
The capital infusion underscores the astronomical infrastructure costs required by frontier AI companies to scale their operations. Recently disclosed filings revealed Anthropic pays SpaceX $1.25 billion monthly to run its models on the company's Colossus supercomputer. The funding caps a transformative first half of 2026 for Anthropic, marked by the release of Claude Opus 4.6, high-profile advertising campaigns, a $30 billion raise in February, and the April unveiling of its Mythos model for cybersecurity vulnerability detection.
