Anthropic has closed a $30 billion Series G funding round, making it the second-largest private tech fundraising in history after OpenAI’s $40 billion raise. The round was led by Coatue and Singapore’s sovereign wealth fund GIC, with participation from numerous investors including Microsoft and Nvidia.
The company reports a post-money valuation between $350 billion and $380 billion, more than doubling its September valuation. Anthropic states its annualized revenue has reached $14 billion, growing more than tenfold annually over the past three years.
The company positions itself as a leader in enterprise AI, stating that 80 percent of its revenue comes from business customers. Anthropic reports that more than 500 customers now spend over $1 million annually on its services, up from around a dozen two years ago. Eight of the Fortune 10 companies use Claude.
Claude Code, an AI coding tool launched in May 2025, has become a significant revenue driver. Anthropic claims the product generates $2.5 billion in annualized revenue, with business subscriptions quadrupling since the start of 2026. The company estimates that 4 percent of all public GitHub commits worldwide are authored by Claude Code.
The funding will support infrastructure expansion, research, and product development. The company, founded in 2021 by former OpenAI researchers, is preparing for a potential initial public offering and has hired Wilson Sonsini for IPO preparations.
