Anthropic is now the most valuable artificial intelligence company in Silicon Valley. The AI giant announced a $65 billion Series H financing at a $965 billion valuation on Thursday. The financing puts its value above rival AI lab OpenAI. CNBC reported in late April that Anthropic was in talks to raise capital. The newest round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and almost triples its valuation from February, when it was worth $380 billion. OpenAI was valued at $852 billion in late March after closing a record-breaking $122 billion funding round. Anthropic's revenue has exploded thanks to its popular AI coding assistant, Claude Code.

The company released its latest model, Claude Opus 4.8, earlier on Thursday. Anthropic has also captivated Wall Street by unveiling Claude Mythos Preview , a model with advanced cybersecurity capabilities that's only available to a select group of companies. "Claude is increasingly indispensable to our growing global community of customers, and we work tirelessly to make tools like Claude Code and Cowork more helpful, more powerful, and more adaptable to their needs," Anthropic CFO Krishna Rao said in Thursday's press release. …
