Over the last decade, digital markets have become increasingly concentrated, not only because of their specificity, which makes them prone to the well-known “winner-takes-all” effect, but also due to mergers and acquisitions. Evidence-based analyses have proven that over the last few years, Big Tech has systematically been involved in mergers and acquisitions operations all over the world. In particular, most of these transactions were not horizontal and targeted very young businesses that were typically no older than 4 years old. This was recently confirmed in an inquiry launched by the Federal Trade Commission (FTC) in February 2020 into past acquisitions by the largest technology platforms that did not require reporting to antitrust authorities at the FTC and the Department of Justice. Indeed, of the 616 transactions examined, 39.3% of those in which the age of the target company could be verified involved firms that were less than 5 years old. Of particular concern are killer acquisitions and the conglomerate effects of mergers, such as platform enveloping strategies in the digital markets.
