Article 17

The Commission may conduct a market investigation for the purpose of examining whether an undertaking providing core platform services should be designated as a gatekeeper pursuant to Article 3(8), or in order to identify the core platform services to be listed in the designation decision pursuant to Article 3(9). The Commission shall endeavour to conclude its market investigation within 12 months from the date referred to in Article 16(3), point (a), In order to conclude its market investigation, the Commission shall adopt an implementing act setting out its decision. That implementing act shall be adopted in accordance with the advisory procedure referred to in Article 50(2).

In the course of a market investigation pursuant to paragraph 1 of this Article, the Commission shall endeavour to communicate its preliminary findings to the undertaking providing core platform services concerned within 6 months from the date referred to in Article 16(3), point (a). In the preliminary findings, the Commission shall explain whether it considers, on a provisional basis, that it is appropriate for that undertaking to be designated as a gatekeeper pursuant to Article 3(8), and for the relevant core platform services to be listed pursuant to Article 3(9).

Where the undertaking providing core platform services satisfies the thresholds set out in Article 3(2), but has presented sufficiently substantiated arguments in accordance with Article 3(5) that have manifestly called into question the presumption in Article 3(2), the Commission shall endeavour to conclude the market investigation within 5 months from the date referred to in Article 16(3), point (a). In such a case, the Commission shall endeavour to communicate its preliminary findings pursuant to paragraph 2 of this Article to the undertaking concerned within 3 months from the date referred to in Article 16(3), point (a).

When the Commission, pursuant to Article 3(8), designates as a gatekeeper an undertaking providing core platform services that does not yet enjoy an entrenched and durable position in its operations, but which will foreseeably enjoy such a position in the near future, it may declare applicable to that gatekeeper only one or more of the obligations laid down in Article 5(3) to (6) and Article 6(4), (7), (9), (10) and (13), as specified in the designation decision. The Commission shall only declare applicable those obligations that are appropriate and necessary to prevent the gatekeeper concerned from achieving, by unfair means, an entrenched and durable position in its operations. The Commission shall review such a designation in accordance with the procedure laid down in Article 4.
