The European Union’s antitrust chief said on Wednesday there may be reason for worry.
Margrethe Vestager, the bloc’s competition commissioner, announced the start of an investigation into whether Amazon is unfairly using data collected about third-party sellers to make its own decisions about products to sell — information that would give it a potentially anticompetitive edge.
The announcement keeps Europe at the center of a debate about how to regulate global technology platforms. Amazon, whose chief executive, Jeff Bezos, is the world’s wealthiest person, has become a particular focus of antitrust scrutiny, as the company’s vast and quickly expanding business dominates online retail and underpins much of the internet through a cloud computing division.
Vestager, the world’s most aggressive regulator of American technology giants, said that Amazon’s dual position as host of the largest online platform for third-party sellers, as well as a retailer of goods, deserved a closer look from European investigators. Her office has sent a number of questionnaires to market participants to learn more about Amazon’s practices.
“The question here is about the data,” Vestager said at a news conference on Wednesday. She said that she wanted to know whether Amazon used data collected from merchants to make its own calculation about “what is the new big thing, what it is that people want, what kind of offers do they like to receive, what makes them buy things?”
