Türkiye’s Competition Authority has closed its abuse of dominance investigation into Sahibinden Bilgi Teknolojileri Pazarlama ve Ticaret AŞ after accepting a package of binding commitments aimed at addressing competition concerns linked to the company’s online vehicle sales activities.
The probe, launched in January 2025, examined whether Sahibinden had breached Article 6 of Law No. 4054 by leveraging its strong position in online vehicle listing services to gain an unfair advantage in the market for second-hand vehicle buying and selling. In particular, the authority focused on Sahibinden’s alleged use of user data collected from both individual and corporate vehicle listings, as well as the competitive impact of extensive advertising and design features promoting its Otobid service.
During the investigation, the Competition Board also expressed concerns about the combination of user data across different services offered by Sahibinden, viewing this practice as a potential restriction of competition. To prevent possible irreparable harm while the case was ongoing, interim measures were imposed in early 2025.
As the investigation progressed, Sahibinden opted to propose commitments to address the authority’s concerns. Following discussions, the Board concluded that the final commitments were adequate, proportionate and capable of being implemented swiftly and effectively. On that basis, it decided in December 2025 to terminate the proceedings.
Under the accepted commitments, Sahibinden will remove Otobid-related promotions from its website and mobile app, stop steering users toward Otobid when posting listings, and prevent the use of non-public listing data for Otobid. In addition, Otobid’s revenues above a defined threshold will be limited to covering its variable costs and advertising expenses.
