The US Federal Trade Commission has opened an antitrust investigation of Microsoft, $MSFT, drilling into everything from the company’s cloud computing and software licensing businesses to cybersecurity offerings and artificial intelligence product

The U.S. Federal Trade Commission (FTC) has launched a wide-ranging antitrust investigation into Microsoft, focusing on its software licensing practices and cloud computing business, according to a source familiar with the matter.

The investigation was approved by FTC Chair Lina Khan as she prepares to step down in January. With Donald Trump set to assume the presidency and expected to appoint a Republican successor who may take a more business-friendly stance, the future of the probe remains uncertain.

The FTC is investigating claims that Microsoft may be leveraging its dominance in productivity software to enforce restrictive licensing terms, making it harder for customers to transfer their data from its Azure cloud platform to competing services, sources previously confirmed.

Additionally, the inquiry is expanding to include Microsoft's cybersecurity and artificial intelligence products, the source said on Wednesday.

Microsoft has not commented on the matter.

Complaints about Microsoft’s cloud computing practices were submitted to the FTC last year as part of a broader examination of the cloud market.

NetChoice, a trade group representing online companies like Amazon and Google that compete with Microsoft in cloud services, has been critical of Microsoft’s licensing policies and its integration of AI tools into Office and Outlook.

"As the world’s largest software company, Microsoft’s dominance in productivity and operating systems software means its licensing decisions have significant impacts," the group stated.

The FTC has not responded to requests for comment. According to a Bloomberg report on Wednesday, the agency has requested an extensive set of detailed information from Microsoft.
