The United States Federal Trade Commission is said to have opened an extensive antitrust investigation into Microsoft Corporation, focusing on its cloud computing and artificial intelligence offerings, sources told Bloomberg on Wednesday.

Insiders say the regulator has requested key details from Microsoft and plans to meet with the company's competitors next week to better understand its business practices. The investigation is said to center on how Microsoft integrates its popular office productivity and security tools into its cloud services, raising concerns about its market power.

Additionally, Microsoft's recent cybersecurity challenges and its position as a government contractor have drawn attention to the company's significant influence on the market.

The company's stock stood 0.39% lower in the after-hours trading.
