Anthropic Secures $65B, Nears $1 Trillion Valuation
Anthropic raised $65 billion in Series H funding at a $965 billion post-money valuation, the company announced on May 28, 2026, making it the most valuable private AI startup, ahead of OpenAI's reported $852 billion mark. The round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN, and includes $15 billion in previously committed hyperscaler investment, including $5 billion from Amazon. Anthropic said its run-rate revenue crossed $47 billion earlier in May 2026, up sharply since its Series G in February. For practitioners, the round funds expanded compute capacity, including new agreements with Amazon, Google/Broadcom TPUs, and SpaceX GPU access, rather than a new product or model.
This is less a product story than a compute-capacity story: nearly all of the detail Anthropic disclosed alongside the raise is about securing chips and data-center capacity to meet demand, not new research or model releases.
What happened
Anthropic announced on May 28, 2026 that it closed a $65 billion Series H round at a $965 billion post-money valuation, led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN. Other significant investors include Blackstone, Brookfield, Temasek, Fidelity, T. Rowe Price, DST Global, General Catalyst, Insight Partners, Jane Street, Lightspeed, and MGX, among others, per Anthropic's own announcement. The round includes $15 billion in previously committed hyperscaler investment, including $5 billion from Amazon, plus new strategic ties to memory and chip suppliers Micron, Samsung, and SK hynix. "This funding will help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens," said Krishna Rao, Anthropic's chief financial officer.
Financial context
Anthropic said its run-rate revenue crossed $47 billion earlier in May 2026, up from its Series G round in February. The $965 billion valuation puts Anthropic ahead of OpenAI's most recently reported $852 billion valuation, making it the most valuable private AI company by that measure, according to Anthropic and corroborating press coverage from TechCrunch, Bloomberg, and NBC News.
Technical context
Anthropic tied the raise directly to compute expansion: the company says it has signed agreements with Amazon for up to five gigawatts of new capacity, with Google and Broadcom for five gigawatts of next-generation TPU capacity, and with SpaceX for GPU access in the Colossus 1 and Colossus 2 clusters. Anthropic says Claude is now the first frontier model available on all three major cloud platforms -- AWS, Google Cloud, and Microsoft Azure -- with AWS remaining its primary cloud and training partner.
For practitioners
For teams building on Claude, the multi-cloud and multi-chip-supplier posture (Nvidia, Google TPUs, and named memory suppliers) is the most actionable signal: it suggests Anthropic is hedging against single-vendor GPU supply constraints, which could matter for enterprise customers evaluating long-term platform risk and capacity guarantees rather than just per-token pricing.
What to watch
Whether Anthropic's revenue run-rate and compute commitments keep pace with the valuation, how the multi-cloud and multi-chip-supplier strategy affects pricing and availability for enterprise customers, and any further disclosures tied to a potential future IPO given the scale of this round.
Key Points
- 1Anthropic raised $65 billion in a Series H round at a $965 billion post-money valuation, announced May 28, 2026.
- 2The raise is tied directly to new compute agreements with Amazon, Google/Broadcom, and SpaceX, plus chip-supply ties to Micron, Samsung, and SK hynix.
- 3Anthropic's run-rate revenue reportedly crossed $47 billion in May 2026, the basis investors cited for the valuation jump since February's Series G.
Scoring Rationale
Score held at 9.1: a $65 billion round at a $965 billion valuation, confirmed directly via Anthropic's own announcement and corroborated by TechCrunch and Bloomberg, is one of the largest private financings on record and directly shapes compute access, cloud partnerships, and competitive dynamics against OpenAI -- industry-shaking by any reasonable standard for AI infrastructure and enterprise-platform practitioners.
