- Anthropic raised $65 billion at a $965 billion post-money valuation in its Series H — likely the last private fundraise before an IPO.
- Round co-led by Altimeter, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, D1 Capital, and others. Samsung, SK Hynix, and Micron joined as strategic infrastructure partners.
- $15 billion of the round consists of previously committed hyperscaler investments (including $5 billion from Amazon announced in April).
- Anthropic’s run-rate revenue crossed $47 billion earlier this month; WSJ reports the company expects a 130% revenue surge into first operating profit.
What Happened
Anthropic closed a $65 billion Series H at a $965 billion post-money valuation, TechCrunch reported on Thursday. The round is co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, and D1 Capital Partners. Strategic infrastructure partners Samsung, SK Hynix, and Micron joined. Institutional investors including Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research participated.
Why It Matters
The $965 billion mark places Anthropic within 4% of OpenAI’s $852 billion post-Series G valuation from March 2026 and meaningfully above OpenAI’s pre-Series G mark. The race for the larger IPO between the two companies — which Bloomberg has documented over the past two weeks — is now down to single-digit-billion-dollar margins.
The round arrives the same day Anthropic released Claude Opus 4.8 — a successor to the Opus 4.7 model launched May 22 — with improved agentic, coding, and honesty-and-self-correction capabilities. The same-day timing is deliberate: Anthropic is sequencing capability disclosure with capital-formation events to maximise the narrative arc into IPO.
Technical Details
Of the $65 billion total, approximately $15 billion is previously committed hyperscaler capital — including $5 billion from Amazon announced in April. The Series H is described in TechCrunch’s reporting as the likely last private fundraising round before an IPO. Altimeter Capital founder and CEO Brad Gerstner said: “Claude‘s latest advancements have driven large-scale adoption among the world’s most demanding organizations. This momentum positions Anthropic to lead the next phase of AI innovation and capture the enormous opportunity ahead.”
Anthropic plans to use the new capital to “advance our safety and interpretability research, expand compute to meet growing demand for Claude, and scale the products and partnerships our customers rely on.” The company is also reportedly planning to more widely launch models on par with Claude Mythos — currently in limited release due to cybersecurity safety concerns. The Wall Street Journal recently reported Anthropic expects a 130% revenue surge to bring it to its first operating profit; run-rate revenue crossed $47 billion earlier this month.
Who’s Affected
Anthropic’s existing institutional investor base — including Google, Amazon, Salesforce Ventures, Lightspeed, Spark Capital, and Menlo Ventures — gains a substantial step-up valuation marker. OpenAI’s planned September IPO at Goldman Sachs and Morgan Stanley faces a competitor with a slightly higher private valuation and faster revenue acceleration. Samsung, SK Hynix, and Micron — the three strategic memory-chip partners — gain deeper commercial integration with Anthropic at a moment when memory bandwidth is a frontier-model bottleneck. The hyperscalers (AWS Bedrock, Google Vertex AI) gain a structurally important commercial relationship.
What’s Next
Anthropic has not announced an IPO timeline. The TechCrunch framing — “likely last private fundraising before debuting on the public markets” — suggests an S-1 filing is in the medium-term horizon. Apollo’s separate $36 billion debt deal to fund AI-chip purchases for Anthropic (reported by Bloomberg the same day) provides a complementary capital-stack signal. The race against OpenAI’s September IPO timeline will shape the second half of 2026.
