Microsoft Corporation's Japanese subsidiary is facing scrutiny from the Japan Fair Trade Commission (JFTC) for possible violations of antitrust laws, following the commission's inspection premises in Tokyo. This investigation comes as the JFTC continues to monitor major IT corporations, particularly those within the GAFAM group (Google, Apple, Facebook, Amazon, Microsoft), for practices that may unfairly influence domestic companies. The current focus revolves around a competitive environment where cloud infrastructure services and AI technologies intersect, indicating a critical landscape for not just local but global business dynamics.

The cloud infrastructure market, which underpins various enterprise systems by providing essential computing resources and data storage, is experiencing rapid growth. According to research firm Synergy Research, the market is projected to expand to $419 billion by 2025, with the fourth quarter of that year alone expected to generate approximately $119.1 billion. Amazon Web Services (AWS) leads the market with a 28% share, followed closely by Microsoft's Azure at 21% and Google at 14%, collectively dominating 63% of the market. These figures highlight the immense financial stakes involved, where even marginal shifts in market share translate to billions in revenue.

The relationship between cloud services and AI is increasingly symbiotic, as advancements in AI technologies drive demand for robust cloud infrastructure to support their deployment. Companies that secure significant shares in the cloud market position themselves favorably in the AI competition, suggesting that control over cloud resources is critical for gaining a competitive edge in the growing field of artificial intelligence. This situation necessitates vigilant monitoring of antitrust practices among leading technology firms, as their actions could profoundly influence market dynamics and innovation trajectories.
