The Turkish Competition Board’s Sahibinden Commitment Decision: A Closer Look At Digital Platform Commitments

1. Introduction

On December 25, 2025, the Turkish Competition Board (“Board”) accepted the revised commitments submitted by Sahibinden Bilgi Teknolojileri Pazarlama ve Ticaret A.Ş. (“Sahibinden”) and terminated the investigation launched against Sahibinden under Article 6 of Law No. 4054 on the Protection of Competition (“Law No. 4054”) concerning alleged leveraging practices associated with Sahibinden's Otobid service. ²

Although the investigation was concluded without a finding of infringement, the decision provides important guidance on the Board's approach to digital platform cases and behavioral commitments in abuse of dominance investigations. In particular, it illustrates how the Board assesses concerns relating to data use, user steering and leveraging in digital ecosystems, as well as the effectiveness of behavioral commitments in addressing those concerns.
