The UK's antitrust watchdog, the Competition and Markets Authority (CMA), has expressed "real concerns" about the consolidation of power in artificial intelligence (AI) by leading technology companies. The CMA's investigation uncovered an interconnected web of over 90 AI-related deals and investments involving major tech firms such as Google, Apple, Microsoft, Meta, Amazon, and Nvidia. This extensive network of investments and acquisitions has raised alarms about the potential for anti-competitive behavior and the stifling of innovation in the rapidly evolving AI sector. The CMA's findings underscore the need for deeper scrutiny of these companies' activities in the AI space to ensure a competitive market and prevent any single entity from dominating the AI landscape.
