Google to Invest Up to $40B in Anthropic: $10B Cash Now at $350B Valuation, 5 GW of TPU Over Five Years

Google has committed up to $40 billion to Anthropic, with $10 billion in cash wired immediately at a $350 billion valuation and an additional $30 billion contingent on performance targets, in a deal disclosed on April 24. The package is the largest single capital-and-compute commitment ever announced for an AI lab.

Inside the deal

The structure unbundles Google's commitment into two layers. The $10B cash tranche prices Anthropic at $350 billion — Anthropic's February mark — and hits the balance sheet immediately. The remaining $30 billion is conditional on Anthropic clearing "certain performance targets" Google did not disclose, leaving the upper bound of the deal tied to milestones rather than guaranteed at signing.

5 gigawatts of TPU over five years

Beyond capital, Google will provide 5 gigawatts of TPU-based compute capacity over the next five years, with the agreement leaving "room to scale further." That sits on top of a 3.5 GW Google/Broadcom partnership Anthropic announced earlier this month, beginning in 2027. Combined, the new commitment more than doubles the compute Anthropic has secured from Google's silicon stack — addressing widespread complaints about Claude rate limits over the past several weeks.

The valuation race: from $350B toward $800B

Anthropic was last priced at $350 billion in February. Investors have since been seeking $800 billion+ valuations in secondary markets, turning Google's $350B entry into a potential paper double inside one quarter. Amazon added $5 billion this week, layered onto its earlier framework of up to $100 billion across 5 GW. The two hyperscalers now back Anthropic's roadmap with parallel multi-GW compute pipelines, and the company has reportedly placed an October 2026 IPO window on its planning calendar.

BlockAI's View

Google's $40 billion is not just a capital event — it is a hardware-supply event. Anthropic now has redundant, multi-GW compute commitments from both Google and Amazon, removing the single-supplier risk that has shadowed OpenAI's Microsoft tether. The conditional $30B tranche turns the deal into a performance-linked capital line more than a one-shot raise; expect unlocks to track Mythos and post-Mythos releases through 2027. For markets, the read-across is the $350B-to-$800B implied secondary spread — the gap between strategic-investor entry and pure financial demand has rarely been this wide.
