Anthropic has raised $65 billion in a Series H round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, valuing the company at $965 billion post-money. The company announced the round on May 29, 2026, on the Anthropic blog, citing run-rate revenue of $47 billion crossed earlier this month. At that multiple, Anthropic is being priced like a growth-stage software business where revenue is expected to roughly double again before investors reassess.
The investor list is unusually broad. Co-leads include Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN. The $65 billion total includes $15 billion of previously committed investments from hyperscalers, among them $5 billion from Amazon. Semiconductor manufacturers Micron, Samsung, and SK hynix are joining as strategic infrastructure partners, a structural signal that Anthropic views memory and chip supply as a constraint on growth, not just a cost line.
The stated uses for the capital are compute expansion, safety and interpretability research, and product development. Anthropic’s CFO Krishna Rao said in the announcement that the funding will help the company “serve the historic demand we are experiencing.” The company did not disclose a split between those allocation buckets.
The compute picture is now very large. Anthropic disclosed 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 access to GPU capacity in Colossus 1 and Colossus 2. That SpaceX relationship is consistent with prior reporting: AI Insiders covered a $1.25 billion per month contract structure tied to the Colossus cluster. At that scale, compute costs become the single biggest variable in Anthropic’s profitability math. AI Insiders previously reported a compute-cost-per-revenue improvement from roughly 71 cents to 56 cents; whether that ratio holds as the SpaceX contract ramps is what determines whether Anthropic’s projected $559 million operating profit materializes.
The $47 billion run-rate also provides the sharpest competitive reference point available. OpenAI’s run-rate was reported at roughly $25 billion in recent coverage, meaning Anthropic is now claiming nearly twice the revenue of its nearest public benchmark. Both figures are company-stated run-rates shared during fundraising, not audited financials. Pre-IPO companies report run-rate at peak momentum and forward-extrapolate monthly figures; the standard caveat applies. Neither number reflects a trailing twelve-month audited result.
The valuation math sits at roughly 21x run-rate revenue. That is aggressive for a company without public financials, but it is defensible if you believe the growth trajectory holds. Claude Code is the clearest growth driver with a reported $2.5 billion subset of the overall revenue figure. Enterprise contract volume, not consumer subscriptions, is what moves that number: Sequoia partner Alfred Lin said in the announcement that both startups and Global 5000 companies are deploying Claude for complex workflows. Claude is now listed as available on AWS, Google Cloud, and Microsoft Azure simultaneously.
The IPO target, which AI Insiders previously placed at October 2026, sits just five months out. At $965 billion post-money, a public offering would mark Anthropic as the second private AI company to cross the trillion-dollar threshold after OpenAI’s reported valuation in early 2025. The gap between private and public pricing at that scale creates real incentive to move quickly before macro conditions shift or a competitor closes the capability gap.
Enterprise procurement teams should expect Anthropic to lean into its multi-cloud position as a negotiating tool with AWS, where it remains the primary training partner. That dynamic gives large customers more leverage on pricing than they had twelve months ago, but it also means Anthropic can push list prices on Claude API tiers upward as the SpaceX compute build-out reduces its marginal cost exposure. Teams currently running Claude under legacy enterprise agreements should benchmark renewal terms against the current published pricing before the IPO window opens.
