Amazon has made a significant move in the AI industry by investing an additional $2.75 billion in Anthropic, a leading generative AI startup known for its Claude chatbot, bringing its total commitment to $4 billion. This partnership marks Amazon's most substantial external investment, surpassing the $1.3 billion put into Rivian. Although maintaining a minority stake without board representation, Amazon will use its AWS platform as Anthropic's primary cloud provider. The investment comes amid intense competition in the AI space, with tech giants like Microsoft and Google making parallel moves, and follows regulatory scrutiny over such strategic tech partnerships. This aggressive investment strategy reflects the tech industry's race to dominate a transformative AI market.
