SAN FRANCISCO — Anthropic raised $65 billion in a Series H funding round at a $965 billion post-money valuation and released its Claude Opus 4.8 model on the same day in 2026. The company’s run rate revenue had already crossed $47 billion in May 2026, and it is expected to post its first-ever profitable quarter in its upcoming earnings. According to The Wall Street Journal, Anthropic expects a 130% revenue surge that will bring it to its first operating profit.

The funding 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. Strategic infrastructure partners Samsung, SK Hynix, and Micron joined the round as well. Of the total, $15 billion consisted of previously committed investments from hyperscalers, including $5 billion from Amazon announced in April 2026.

Anthropic plans to use the new funds 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 simultaneous release of Claude Opus 4.8 introduced improvements in agentic tasks, advanced coding, and a stronger focus on honesty and self-correction. The company is also planning a wider launch of models comparable to its cybersecurity model Mythos, which had been limited due to safety concerns.

Brad Gerstner, founder and CEO of Altimeter Capital, 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." Dan Ives, analyst at Wedbush Securities, said in a podcast interview, "Right now, in terms of Anthropic, it's the best model in the world, and I don't think there's a dispute there."
