The Belgian Competition Authority (the BCA) announced today the opening of an investigation into AutoScout24 Belgium (AutoScout 24).

AutoScout24 operates an online platform and an app which connect sellers and buyers of used vehicles. The BCA suspects AutoScout24 of “limitations to the portability of data entered on AutoScout24.be by professional sellers” which would discourage these sellers from “multi-homing” or relying on competing platforms.

The BCA opened its investigation on the basis of Article 102 of the Treaty on the Functioning of the European Union and/or Article IV.2 of the Belgian Code of Economic Law, which suggests that the BCA considers AutoScout24 to have a dominant position on the market for specific intermediation services.

The BCA appears to be investing considerable time and resources in the digital sector. Just a couple of weeks ago, it started an investigation into Google’s possible abuse of dominance in the online advertising sector (see, VBB Belgian Antitrust Watch of 27 February 2026). The digital sector features among the BCA’s enforcement priorities.

While the Google investigation followed unspecified “reports” of problematic practices, the AutoScout24 investigation is based on a formal complaint.
