Key Takeaways

  • Belgium’s BCA says concerns center on Google’s ad-tech intermediation stack (including AdX and ad buying tools), and alleges potentially discriminatory terms and treatment that could harm users and rivals; the case is CONC-RPR-26-0004 and is at an early stage. (belgiancompetition.be)
  • The BCA is assessing potential breaches of EU abuse-of-dominance rules (Article 102 TFEU) and Belgian competition law, including Belgium’s “economic dependence” provision—an extra legal hook beyond classic dominance abuse. (belgiancompetition.be)
  • The Belgian action lands as the European Commission is also testing complaints about Google Search ad auctions potentially “artificially increasing the clearing price,” according to a February 2026 letter to advertisers (feedback due by March 2, 2026), suggesting price-setting mechanics are becoming a central regulatory focus.
