Anthropic seeks $10B funding as Claude hits 32% market share

Anthropic, the AI startup behind the Claude assistant, is reportedly in advanced negotiations to raise as much as $10 billion in a new funding round. According to Bloomberg, the amount is double the $5 billion reported in late July due to strong investor demand. The company previously closed a $3.5 billion Series E in March at a $61.5 billion post-money valuation. Anthropic declined to comment on the latest funding talks.

Meanwhile, Anthropic's Claude continues to gain enterprise traction. Menlo Ventures reports Claude now holds 32% of the AI model market share, the highest among competitors, driven by releases like Claude Sonnet 3.5, Sonnet 4, Opus 4, and Claude Code. The company recently expanded Claude's context window fivefold to 1 million tokens, enabling processing of entire codebases or dozens of research papers in a single prompt. In a move to expand government adoption, Anthropic offered Claude to all three branches of the U.S. government for $1 per agency per year, a broader offer than OpenAI's executive-branch-only deal.
