Amazon (AMZN.US) is considering an additional investment in AI startup Anthropic.

Amazon (AMZN.US) is reportedly considering an additional investment in generative AI startup Anthropic, which it previously invested $4 billion in. The second investment could be in the tens of billions, according to people familiar with the matter, and may require Anthropic to use servers powered by Amazon's AI chips, the report said.

Amazon launched two AI-focused chips, Graviton4 and Trainium2, in November 2023. Anthropic typically uses Nvidia's (NVDA.US) AI chips.

Last month's reports said that Anthropic was in talks with investors to raise additional funds, and its valuation could be close to $40 billion. Its rival OpenAI announced a $6.6 billion funding round last month, valuing the company at $157 billion.
