Google has committed up to $40 billion to Anthropic, according to Anthropic's blog post. It owns less than 15 percent of the company.
On Friday the search giant confirmed a $10 billion cash investment now, with up to $30 billion more contingent on performance targets neither company will disclose. Google's stake is capped contractually at 15 percent, carries no voting rights, no board seats, and no board observer privileges. The structure keeps Anthropic independent on paper while making Google its largest single backer and most important cloud customer simultaneously.
Anthropic's revenue run rate has crossed $30 billion, up from $9 billion at the end of 2025 — 3.3 times growth in roughly four months. More than 1,000 enterprise customers now spend $1 million or more annually on the platform, doubling from 500 in under two months, according to Anthropic's blog post. Claude holds 32 percent of the enterprise large language model API market, ahead of OpenAI's GPT-4o at 25 percent, according to a Menlo Ventures enterprise survey reported by TechCrunch in July 2025.
Amazon made a comparable move days earlier, bringing its total potential commitment to $25 billion, Reuters reported. Two cloud giants are paying to lock in the same startup simultaneously. The terms they accepted suggest neither could get a better deal by walking away.
Google's existing stake sits around 14 percent from more than $3 billion in prior investments. The new $10 billion tranche pushes it close to the 15 percent contractual ceiling, TechCrunch reported. The ceiling appears designed to keep Anthropic economically dependent without crossing the ownership threshold that would trigger regulatory review.
The contingent $30 billion is the unresolved part. If the undisclosed targets are commercial milestones like revenue thresholds or customer counts, this is a growth equity deal with favorable terms and no governance strings. If they are capability milestones like benchmark performance scores or safety evaluation results, then Google is not just an investor. It is a quiet curator of which AI capabilities get funded.
Anthropic is also preparing for a public listing. The company has held early talks with Goldman Sachs, JPMorgan, and Morgan Stanley about a potential IPO that could come as early as October 2026, with an expected raise exceeding $60 billion, according to The Next Web. Internal target valuations range from $400 billion to $500 billion — roughly half what secondary markets are currently pricing the company at. On Forge Global, shares have traded as high as $1 trillion, Silicon Snark noted.
Anthropic was founded in 2021 by Dario Amodei and colleagues who left OpenAI over concerns about AI safety. Its public benefit corporation structure was designed to keep it answerable to a mission, not a shareholder base. What happens when one of its largest shareholders is also its most direct competitor and most important cloud provider? Anthropic just signed that deal.
