Google to Invest Up to $40 Billion in Anthropic, Doubling Down on Claude

Google will invest up to $40 billion in Anthropic, the maker of Claude, in one of the largest single commitments to an AI lab on record. The deal, reported on April 24, includes $10 billion in cash now at a roughly $350 billion valuation, with another $30 billion contingent on Anthropic hitting performance milestones.

The investment lands just days after Amazon disclosed plans to put up to $25 billion of its own into Anthropic, underscoring how quickly the AI infrastructure arms race has escalated. Google previously held an estimated 14 percent stake in the startup after committing more than $3 billion across rounds dating back to 2023.

Beyond cash, Google Cloud has agreed to deliver five gigawatts of computing power to Anthropic over the next five years, with room to expand. The capacity is intended to ease what Anthropic has called "inevitable strain" on its infrastructure as enterprise, developer and consumer demand for Claude continues to surge.

Anthropic's annualized revenue has crossed $30 billion this month, up from roughly $9 billion at the end of 2025 — growth driven heavily by Claude Code's traction with developers. The company's implied secondary-market valuation recently brushed $1 trillion, eclipsing OpenAI on that measure.

For Google, the move spreads its AI bets across both its in-house Gemini program and a fast-rising rival — a hedge against any single lab dominating the frontier. For Anthropic, the dual backing of Amazon and Google secures the compute it needs to keep training successively larger Claude models without taking a single hyperscaler as its sole patron.
