The US Federal Trade Commission is expanding its antitrust probe of Amazon's retail business to now also include Amazon's cloud business unit, Amazon Web Services, according to Bloomberg.
FTC investigators have been talking to software companies about AWS' business practices, Bloomberg reported, citing people familiar with the matter. This would represent an expansion of the FTC's probe into Amazon's online retail business.
AWS has a 48-percent share of the public cloud business versus a 16-percent share for Microsoft, according to Gartner. Alibaba (8 percent), Google (4 percent) and IBM (2 percent) also compete in the space.
AWS posted net sales of US$9 billion for its third fiscal quarter 2019, or nearly 13 percent of Amazon's total sales. AWS sales were up nearly 35 percent year-over-year. However, AWS operating income in the quarter of US$2.26 billion accounted for nearly 72 percent of the company's total operating income of US$3.16. The quarter ended 30 September.
Amazon Web Services did not respond to a request for further information as of press time.
The investigation into AWS is only one of several moves by the US government to examine whether tech giants are potentially abusing their market positions.
The US Justice Department in July said it is looking at how multiple unnamed market-leading online platforms to see how they achieved their market power and whether they are engaging in practices that have reduced competition or stifled innovation.
Possible targets of that probe include Apple, Amazon, Facebook, and Google.
A month earlier, seven US senators wrote letters to the FTC and the Justice Department for details of their investigations of those four companies following earlier reports of the potential investigations.
A US House of Representatives panel, the House Subcommittee on Antitrust, Commercial and Administrative Law, in September followed up those probes with an eight-page survey asking the online companies about their industry's competitive and regulatory environments.
