Anthropic is circling a funding round that would value the company at more than $900 billion, with sources indicating the transaction could close within the next two weeks. Amazon disclosed Tuesday it will invest up to an additional $25 billion in the company as part of a broader infrastructure partnership, extending a relationship that began with a $4 billion commitment in September 2023. The new capital structure marks the largest single AI-focused valuation event since OpenAI's $157 billion round in October 2023, and would position Anthropic as the second-most-valuable private AI firm globally.
The $25 billion Amazon commitment is structured as convertible debt tied to compute infrastructure rather than pure equity, according to people familiar with the terms. Anthropic will receive access to Amazon Web Services' next-generation Trainium2 chips and priority allocation of GPU clusters across AWS regions, with compute credits converting to equity at a discount to the round's headline valuation. The arrangement mirrors Microsoft's $13 billion OpenAI partnership, where Azure compute credits constitute roughly 75% of the stated investment value. Amazon's stake in Anthropic now totals approximately $29 billion in committed capital, though the effective cash outlay remains substantially lower when infrastructure components are excluded.
The valuation reflects demand for models competitive with OpenAI's o-series reasoning systems. Anthropic's Claude 3.5 Sonnet holds 18% share of API traffic among enterprise customers, per Menlo Ventures' January benchmarking data, trailing only OpenAI's GPT-4 family at 63%. The company's annualized revenue run rate reached $1.8 billion in December 2024, up from $875 million six months prior, driven by adoption in legal document review, code generation, and customer service automation. Enterprise contracts now average $420,000 annually, compared to $180,000 in early 2024, as Fortune 500 deployments expand beyond pilot phases.
Operators should monitor two signals: Anthropic's GPU lease commitments through mid-2025, which will indicate whether the company is pre-positioning for inference scale beyond current revenue justifies, and Amazon's Q2 guidance on AWS AI revenue, expected April 24. Fund managers tracking AI infrastructure plays should note that Broadcom, Marvell, and Arista Networks supply networking silicon for AWS Trainium clusters, with Anthropic's expanded footprint likely requiring 15-20% incremental data center interconnect capacity across three AWS regions. Family offices with exposure to secondary AI stakes should verify liquidity terms, as lockup periods on rounds above $50 billion valuation typically extend to 36 months versus the standard 24.
The transaction's two-week timeline aligns with Amazon's April 1 fiscal quarter close, suggesting the convertible structure is designed to allow booking before Q1 earnings. If valuation holds, Anthropic will have appreciated 620% in sixteen months.
The takeaway
Anthropic's $900B round, backed by Amazon's $25B compute commitment, reshapes AI capital as infrastructure-linked debt displaces traditional equity.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
