The specific roles of Microsoft, OpenAI, and Nvidia in the artificial intelligence industry that have prompted increased antitrust scrutiny by US regulators are their dominant positions and influence in the burgeoning AI market. Microsoft is a key investor in OpenAI, with an estimated $13 billion investment, and has made deals with other AI companies. This relationship raises concerns about whether it gives Microsoft and OpenAI an unfair advantage, particularly around the technology for large language models such as ChatGPT.
On the other hand, Nvidia dominates the GPU market, with an estimated 80% share, and its software tools primarily work with its own GPUs. This market dominance leaves Nvidia open to claims of being a monopoly.
The US Department of Justice (DoJ) and the Federal Trade Commission (FTC) have reached an agreement to investigate these companies for potential antitrust violations. The DoJ will focus on investigating whether Nvidia has violated antitrust laws, while the FTC will look into OpenAI and Microsoft's potentially anticompetitive behavior in the AI space2.

The DoJ will focus on investigating whether Nvidia, the leading maker of chips that train and operate AI systems, has broken antitrust laws. On the other hand, the FTC will scrutinize OpenAI, the company behind the ChatGPT chatbot, and Microsoft, OpenAI's biggest investor and a considerable financial backer of other AI companies.

The Department of Justice (DOJ) is investigating whether Nvidia, a leading maker of chips that train and operate AI systems, has violated antitrust laws. Antitrust laws are designed to promote fair competition in business and prevent monopolies. The investigation aims to ensure that Nvidia has not engaged in any anticompetitive practices that could potentially harm the market or consumers.
