Two companies that benefited the most from AI average, Nvidia and Microsoft, are the most exposed to antitrust investigations for AI monopolies. Regulatory authorities have shifted their approach, acting quickly against potential monopolistic practices instead of taking years to intervene.

Notable investigations include the US Department of Justice examining Nvidia's alleged anticompetitive behaviour in the GPU market and the Federal Trade Commission (FTC) probing Microsoft's$13 billion investment in OpenAI and strategic staff acquisitions from Inflection. The UK's Competition and Markets Authority (CMA) is also investigating, particularly concerned about the over 90 partnerships tech giants have formed with large language model developers since 2019, potentially stifling competition.

Politically, there's a risk that excessive intervention could be seen as stifling innovation, particularly in the face of global competitors like China. Regulators must balance fostering competition with enabling innovation, ensuring that the rise of generative AI, which promises significant technological upheaval, does not result in a market dominated by a few powerful players.
