TikTok, owned by ByteDance, asks the Court of Justice of the European Union (CJEU) to overturn its designation as a “gatekeeper” under the EU’s Digital Markets Act (DMA). The appeal is heard by the CJEU Grand Chamber in Case C-627/24 P, described as the first DMA gatekeeper challenge to reach the bloc’s highest court. ByteDance argues that regulators are applying the DMA too aggressively to fast-growing companies and that TikTok should not be treated like “Big Tech royalty.” The company seeks to scrap the gatekeeper label, which brings additional obligations under the DMA. The proceedings occur as the court reviews whether the designation and the approach taken by EU authorities are appropriate under the DMA framework. Other coverage frames the case as a test of how the DMA’s criteria are interpreted and applied to determine which platforms must comply with stricter rules. The sources agree on the parties, the court venue, the timing of the hearing, and the core issue: whether TikTok can successfully challenge its gatekeeper status.
