The Federal Trade Commission is investigating whether Big Tech investments into some of the largest artificial intelligence developers are diminishing the competitive market and violating antitrust laws.

The FTC issued orders to Amazon, Google, Microsoft, OpenAI, and Anthropic on Thursday inquiring about their investments and partnerships involving the development of generative AI. Microsoft invested over $10 billion into OpenAI and has implemented its models into several of its products. Amazon and Google, meanwhile, have also invested billions into Anthropic.
