Anthropic has raised $13 billion in a Series E financing round led by Amazon and Google, according to Reuters. The deal marks one of the largest private funding rounds in the AI sector this year and underscores continued investor appetite for leading model developers.

The new capital pushes Anthropic’s valuation above $150 billion, reflecting strong demand for its Claude family of AI models. The company has emerged as one of the most closely watched rivals in the generative AI market, where access to computing power, enterprise customers, and model performance remains highly competitive.

Amazon and Google’s participation highlights how major cloud and technology companies are deepening their ties to frontier AI firms. For Anthropic, the funding provides more room to expand infrastructure, research, and product development as the race intensifies among the industry’s top players.

The announcement comes as investors continue to pour money into artificial intelligence despite mounting questions about costs, regulation, and long-term profitability. For now, the size of the round suggests confidence that demand for advanced AI tools remains strong across consumer and business markets.
