Anthropic Raises $65B, Nears $1T Valuation
Anthropic closed a $65 billion Series H at a $965 billion post-money valuation, a financing the company says may be its last private raise before an IPO. The round was co-led by Altimeter Capital, Dragoneer, Greenoaks, Sequoia Capital, Capital Group, Coatue, D1 Capital Partners and included institutional investors such as Baillie Gifford, Blackstone, Brookfield, D.E. Shaw Ventures, DST Global and Fidelity. Strategic infrastructure partners Samsung, SK Hynix and Micron also participated. The company said $15 billion of the round comprised previously committed hyperscaler investments — including $5 billion from Amazon. Anthropic released Claude Opus 4.8 on the same day and said it will use funds to expand safety research, compute for Claude, and scale products and partnerships. The startup reported a run-rate revenue above $47 billion and expects profitability following a projected revenue surge.
A $65B Series H valuing Anthropic near $1T — combined with a major model release and large enterprise revenue run rate — materially accelerates AI foundational-model competition, enterprise adoption, compute demand, and potential downstream impacts on advertising and marketing technology.

Anthropic Nears $1T After $65B Series H
Anthropic announced a $65 billion Series H financing at a $965 billion valuation on May 28, 2026, making it the most valuable private AI startup and surpassing rival OpenAI. The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital. Anthropic reported a $47 billion revenue run rate, up from $30 billion earlier this year and $10 billion last year, driven in part by its Claude Code coding assistant. The company also released its latest model, Claude Opus 4.8, and is offering a limited Mythos Preview to select customers. CNBC reported OpenAI’s valuation at $852 billion following its recent funding round.
Anthropic $50B raise could value company at $900B+
Anthropic is soliciting investor allocations for a private financing expected to be roughly $50 billion and could close within two weeks, according to sources. The company has been targeting a valuation near $900 billion, and strong demand from investors could push the final price higher. Some earlier backers (notably those who invested in 2024 or earlier) are reportedly skipping this round and may wait to sell shares in an anticipated IPO later this year. Anthropic says its fundraising will support large-scale computing needs; the company recently reported an annual revenue run rate above $30 billion, with sources placing it closer to $40 billion. Anthropic’s prior round in February valued the company at $380 billion; at a $900 billion valuation it would exceed OpenAI’s recent $852 billion post-money mark.
Anthropic Secures $30 Billion, Valuation Soars to $380 Billion
Anthropic announced the close of a $30 billion funding round at a $380 billion post-money valuation. The round was led by Coatue and Singapore sovereign wealth fund GIC, with participation from D. E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ and MGX. Anthropic said the raise includes a portion of previously announced commitments from Microsoft (up to $5 billion) and Nvidia (up to $10 billion). The company reported annualized revenue of $14 billion (up from roughly $10 billion last year) and said Claude Code’s annualized revenue reached $2.5 billion. Anthropic plans to use the capital to expand infrastructure, research and enterprise-grade products; it also recently unveiled a new model, Claude Opus 4.6. The move follows similarly large rounds for OpenAI and reflects heavy capital flows into foundation-model AI development.
