Anthropic has secured $4 billion in a Series E financing round led by Amazon, lifting the artificial intelligence company's valuation to $60 billion, according to Reuters. The deal underscores continued investor appetite for leading AI developers as competition intensifies across the sector.

The new capital gives Anthropic additional room to expand its research, product development and computing capacity at a time when demand for advanced AI tools remains strong. Amazon's involvement also deepens an already significant relationship between the cloud giant and the startup.

Anthropic has emerged as one of the most closely watched companies in the AI market, alongside rivals such as OpenAI and Google-backed competitors. The latest funding round reinforces how rapidly valuations in the industry continue to climb, despite broader scrutiny over costs, safety and the pace of commercialization.

The size of the investment reflects both the strategic importance of AI infrastructure and the intense competition among major technology firms to secure early access to next-generation models and services.
