Ankara, January 15, 2026 — The Turkish Competition Board has terminated its investigation into Sahibinden Bilgi Teknolojileri Pazarlama ve Ticaret AŞ after accepting a set of commitments offered by the company.
The investigation was launched on January 16, 2025, under Article 41 of Law No. 4054, to determine whether Sahibinden had violated Article 6 of the same law. The probe focused on concerns that Sahibinden may have used user data obtained from its online platform services for corporate and individual vehicle sales in the separate market for online second-hand vehicle buying and selling, and whether intensive advertising expenditures related to its Otobid service strengthened parameters enabling a dominant position.
In addition, the Board had assessed that Sahibinden’s conduct of combining non-public user data obtained from its corporate and individual vehicle listing services with its other services constituted serious indications of a violation of Article 6. On this basis, the Board decided on January 16, 2025, to impose interim measures under Article 9(4) of Law No. 4054 to prevent irreparable harm until a final decision was issued.
During the investigation, Sahibinden requested the opportunity to submit commitments to address the allegations. Following discussions with the authority, the company presented a final commitments package. These included refraining from displaying Otobid services on the Sahibinden website and mobile application, not directing users to Otobid during the advertisement posting process, preventing the use of non-public data obtained from corporate or individual vehicle listings for Otobid services through the adoption of all necessary organizational, operational, administrative and technical measures, and ensuring that, after a certain threshold is exceeded, total revenues from Otobid services cover variable costs and advertising expenditures related to those services.
The Board concluded that the commitments were proportionate to the competition concerns under investigation, capable of remedying those concerns, implementable within a short period, and effective. Accordingly, by its decision dated December 25, 2025, and numbered 25-49/1208-683, the Competition Board decided to terminate the investigation pursuant to Article 43 of Law No. 4054.
