Anthropic Secures $65 Billion Funding Round, Approaches $1 Trillion Valuation Before IPO

Anthropic has secured $65 billion in fresh funding at a post-money valuation of $965 billion, a milestone that could represent the company’s final private fundraising round before it moves toward the public markets.

Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, D1 Capital Partners, and several other investors jointly led the Series H financing. The round also attracted participation from major institutional firms, including Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global, and Fidelity Management & Research.

Several strategic infrastructure partners also joined the financing, including Samsung, SK Hynix, and Micron. Anthropic noted that $15 billion of the total raise consists of previously committed investments from hyperscale technology partners, including the $5 billion commitment from Amazon that was announced earlier this year.

Just weeks ago, reports suggested Anthropic was close to completing a $50 billion fundraising effort, with investors aggressively seeking access to the company. According to reports, one institutional investor was prepared to commit up to $5 billion solely to secure a meeting with Anthropic’s chief financial officer, Krishna Rao.

The company said the new capital will be used to advance its safety and interpretability research, expand compute capacity to meet growing demand for Claude, and continue scaling products and partnerships relied upon by customers around the world.

The funding announcement coincides with the release of Claude Opus 4.8, Anthropic’s latest AI model, which delivers stronger performance in agent-based workflows and advanced coding tasks, as well as enhanced self-correction capabilities. The company is also reportedly preparing a broader rollout of models comparable to its powerful cybersecurity-focused Mythos system, which has so far been released only in a limited capacity due to safety considerations.

Anthropic’s growth has accelerated significantly since its previous fundraising round, particularly among enterprise customers adopting Claude Code. The company recently stated that its annualised revenue run rate surpassed $47 billion. At the same time, a Wall Street Journal report indicated that Anthropic expects revenue to increase by 130%, potentially leading to its first operating profit.

“Claude’s latest advancements have driven large-scale adoption among the world’s most demanding organisations. This momentum positions Anthropic to lead the next phase of AI innovation and capture the enormous opportunity ahead,” said Altimeter Capital founder and CEO Brad Gerstner.

Anthropic continues to compete closely with OpenAI for market share, enterprise adoption, and investor attention as both companies move toward eventual public offerings. OpenAI completed a massive $122 billion funding round in March, achieving an $852 billion post-money valuation.

Meanwhile, Elon Musk’s SpaceX, which combined operations with xAI earlier this year, is reportedly targeting a $2 trillion valuation through its upcoming IPO while seeking to raise more than $75 billion in new capital.
