Abstract: The Bundeskartellamt has designated Alphabet, Meta, and
Amazon as 19a firms. Thus, they are potentially subject to specific
competition law interventions under a special procedure. In these three
designation decisions, market definition plays an important role. This
article points to several noteworthy aspects that concern market
definition. In all decisions the authority focuses on one national market,
arguing that the respective platform operator is dominant. The
authority’s considerations are made at a somewhat aggregate level,
abstracting from differences across market segments.
