Anthropic closes $65 billion Series H round at $965 billion valuation, positioning for imminent IPO

Anthropic has closed a $65 billion Series H funding round at a $965 billion post-money valuation, according to TechCrunch. The round may represent the company’s final private capital raise before a public listing, though no IPO date has been officially announced. The capital includes $15 billion in previously committed investments from major cloud providers, including $5 billion from Amazon that was announced in April.

Lead Investors and Strategic Participation

The Series H round was co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, and D1 Capital Partners. Institutional investors including Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research also participated.

Notably, strategic infrastructure suppliers—Samsung, SK Hynix, and Micron—joined the round alongside the financial investors. According to TechCrunch, investor demand for Anthropic equity was so intense that one institutional investor pledged $5 billion solely to secure a meeting with Anthropic CFO Krishna Rao in the weeks before the round closed.

Claude Opus 4.8 Release and Product Strategy

Anthropic announced Claude Opus 4.8 on the same day as the funding close. According to TechCrunch, the model improves performance on agentic tasks, advanced coding, and focuses on “honesty and self-correction.” The company is also reportedly preparing a wider public launch of its Mythos cybersecurity model, which has previously been available only in limited distribution due to safety considerations.

Revenue Trajectory and Competitive Standing

According to TechCrunch, Anthropic’s revenue run rate crossed $47 billion in May 2026, driven by enterprise adoption of Claude Code. The Wall Street Journal has reported that Anthropic projects significant revenue growth ahead, though the specific rate was not confirmed in the TechCrunch article.

Anthropic’s $965 billion valuation trails OpenAI’s $852 billion post-money valuation from its $122 billion Series round in March 2026, despite Anthropic’s larger absolute funding amount. Both companies are preparing for public listings in an accelerating race to capital markets. Separately, Elon Musk’s xAI—which merged with SpaceX earlier in 2026—is targeting a $2 trillion valuation and seeking more than $75 billion in its pending IPO, according to TechCrunch.

Why This Matters

Anthropic’s proximity to a $1 trillion valuation signals that enterprise infrastructure buyers now face a choice between three near-equivalent competitors (Anthropic, OpenAI, and xAI) all preparing public offerings. Procurement teams at Fortune 500 companies will likely accelerate vendor consolidation decisions ahead of IPO pricing disclosures, since public company governance and financial transparency may affect long-term SLA commitments and pricing stability. The participation of infrastructure suppliers like Samsung and SK Hynix suggests chipmakers are hedging bets on model-provider dominance by taking equity stakes, a shift from prior rounds where capital flows were largely from financial investors.
