An investigation in accordance with Article 41 of the Act no 4045 was launched on Sahibinden Bilgi Teknolojileri Pazarlama ve Ticaret AŞ (Sahibinden) with the decision dated 16.01.2025 and numbered 25-02/47-M, to determine if the undertaking concerned violated Article 6 of the same Act.

The concern within the framework of the investigation was the question of whether Sahibinden violated Article 6 of the Act no 4054 by utilizing the user data it obtained in the markets for “online platform service for the sale of vehicles by corporate members” and “online platform service for the sale of vehicles by individual members” in the online second-hand vehicle buying and selling services market, and by the power it acquired through the extensive ad expenditures concerning the Otobid service and through the parameters that facilitated its dominant position.

In addition, Sahibinden’s practice of merging the user data it obtained within the framework of its online platform services for the sale of vehicles by corporate members and online platform services for the sale of vehicles by individual members with the other services it provided was evaluated as a significant finding suggesting that competition was violated under Article 6 of the Act, and the Board took the decision dated 16.01.2025 and numbered 25-02/47-29 to impose interim measures as per Article 9.4 of the Act no 4054 on Sahibinden in order to prevent irreparable damages until the final decision is taken.

As the investigation process was ongoing, Sahibinden requested to submit commitments to eliminate the allegations comprising the subject of the investigation, and the final commitments text was presented as a result of the discussions held. Accordingly, it has been decided that the following commitments offered by Sahibinden are proportionate to the competitive problems under investigation, sufficient to eliminate these problems, rapidly implementable and effectively applicable, and the Board decision dated 25.12.2025 and numbered 25-49/1208-683 was taken to terminate the investigation under Article 43 of the Act no 4054: 

1. There will be no displays concerning the Otobid service on the Sahibinden website and Sahibinden mobile application,
2. Users will not be directed to the Otobid service when posting listings on the Sahibinden website and the Sahibinden mobile application,
