Anthropic Plans Major London Expansion for 800 Staff
Anthropic announced plans to expand its London presence with new office space for 800 people in the Knowledge Quarter, where major AI firms including OpenAI and Google DeepMind are based. The company currently employs more than 200 people in London. Anthropic framed the move as a strategic expansion of a key research and commercial hub and follows OpenAI’s announcement of a permanent London office. Recent product and financial updates cited in the announcement include Anthropic’s Claude Code coding agent, the Mythos AI model, a February raise of $30 billion at a $380 billion valuation, reported VC interest at an $800 billion valuation, and an annual run-rate revenue exceeding $30 billion with over 1,000 customers spending more than $1 million each.
Major AI company expanding London presence signals intensified talent competition, regulatory and commercial engagement in a key global AI hub; coupled with large fundraising and revenue figures, the move has meaningful industry implications but is not a platform policy or technical standard change.

US AI Giants Expand Major Operations in London
Several U.S. AI and tech companies are rapidly expanding physical and hiring footprints in London to access the city’s deep technical and commercial talent pools. Anthropic announced an April expansion securing office space for 800 people in the Knowledge Quarter, and OpenAI has said it will increase headcount in the city. Other moves include Cursor planning a London headquarters, Google moving teams into a new 11‑storey Kings Cross building, and firms such as Databricks, Salesforce, Rivian and Palantir growing headcount or campuses. Analysts and executives cite London’s decade‑long AI research ecosystem (anchored by DeepMind), access to finance, and universities as key draws. Challenges noted include a shortage of high‑quality office space (a British Land shortfall estimate to 2030) and whether UK infrastructure — power, compute, housing and transport — can scale to support rapid AI growth.
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.
Anthropic in talks to raise funds at $900B valuation
Anthropic is reportedly in private talks with investors to raise new capital at a valuation of $900 billion, which would exceed OpenAI’s recent valuation of about $852 billion. CNBC says no term sheet has been signed and discussions are ongoing. Anthropic has recently released Claude Opus 4.7 and the selective-access Claude Mythos Preview, and has said its business has reached $30 billion in annualized revenue (roughly $10 billion in revenue last year). The company has secured major compute and investment arrangements with hyperscalers: Amazon agreed to invest up to $25 billion and provide up to 5 gigawatts of compute capacity, and Anthropic announced a Google–Broadcom compute arrangement (5 GW) while Google indicated plans to invest up to $40 billion. Sources say Anthropic seeks fresh capital largely to buy the compute needed to run advanced models like Mythos.
