Data-Driven Tools, Ancillary Services and Competition Law

At the annual seminar of the WU’s Institute of Business Law in Retz (5 and 6 March 2026), Franziska Guggi and David Führer presented recent insights from their research. Franziska discussed data-driven tools that competition authorities rely on in their enforcement work, pointing to legal implications of the use of said tools. David discussed ancillary services that digital gatekeepers rely on, which only come under the Digital Markets Act under specific circumstances and therefore open up a number of questions as to how they should be treated.
