Amazon.com Inc. is investing an additional $4 billion in artificial intelligence startup Anthropic, boosting its stake in one of OpenAI’s chief rivals.

The new infusion, announced by the companies on Friday, follows a $4 billion investment in Anthropic completed earlier this year. That deal included provisions that Anthropic use Amazon Web Services data centers for some of its computing needs, as well as AWS-designed AI chips. Anthropic also has close ties with Alphabet Inc.’s Google.
