Why Microsoft, OpenAI and Nvidia are facing anti-monopoly probes

The United States Department of Justice and the Federal Trade Commission (FTC) have reportedly reached a deal on how they will pursue an antitrust investigation into tech giants Microsoft, Nvidia, and Open AI. The companies are all major players in generative AI: OpenAI is the nonprofit startup behind ChatGPT, the blockbuster AI-powered chatbot. Microsoft, the world's largest company by market capitalisation, has invested more than 13bn in OpenAI and holds a 49 percent stake in the company's for-profit subsidiary. Chipmaker Nvidia is a global leader in graphic processing units (GPU), a key piece of hardware needed in AI. The company recently hit a 3 trillion valuation, surpassing Apple to become the world's second-largest company.
