Nvidia is facing an antitrust investigation by the U.S. Department of Justice, focusing on its dominant market position in the artificial intelligence sector and whether it has taken measures to stifle competition, including penalizing suppliers that do not use its AI chips. This news has led to a significant drop in Nvidia's stock price, resulting in a market value loss of $279 billion. Although the overall trend of stock prices remains an upward trajectory, the AI boom has driven high sales of its expensive chips. Nvidia's recently launched Blackwell series AI chips are facing delayed market release due to design flaws, intensifying competition with rivals.

The U.S. Department of Justice and the Federal Trade Commission may initiate an antitrust investigation into the relationship between OpenAI and Microsoft over concerns that their collaboration may create unfair competition in the artificial intelligence market. This news comes less than two weeks after the European Commission announced a review of the partnership between Microsoft and OpenAI.
