TikTok joins Meta in appealing against its EU DMA “gatekeeper” status, saying the service is “arguably the most capable challenger to more entrenched” rivals
TikTok on Thursday joined Meta (META.O) in appealing against the “gatekeeper” status under the Digital Markets Act …
Context & Ripple Effects
TikTok’s challenge followed Meta’s separate appeal of DMA designations for Messenger and Marketplace, making the early litigation a test of how broadly the EU could classify major digital services as gatekeepers. Meta’s parallel challenge to Messenger and Marketplace underscored that the dispute was about the law’s scope as well as any one platform.
The case later produced a clear legal waypoint: the General Court found TikTok large enough for DMA coverage, rejecting ByteDance’s challenge while leaving a further appeal route. That outcome sits alongside the companies’ separate successful challenge to the DSA fee methodology, showing that EU platform rules can face different results depending on the legal mechanism at issue.
First-order effects
- TikTok and Meta put their respective designations before the EU courts, forcing the Commission to defend its tests for identifying gatekeeper services.
- TikTok’s appeal centers the claim that it competes with more established platforms, while its DMA status subjects that competitive framing to a formal legal assessment.
Second-order effects
- The litigation gives other designated platforms a clearer incentive to contest borderline classifications and the evidentiary basis for individual service designations.
- The later rejection of ByteDance’s DMA challenge strengthens the Commission’s position that rapid platform growth can outweigh a company’s challenger narrative in gatekeeper assessments.
Third-order effects
- If courts continue to uphold broad DMA coverage while scrutinizing individual implementation choices, platform regulation is likely to become a recurring cycle of designation, compliance, and targeted judicial review.
- The case highlights an increasingly consequential distinction in digital competition policy: a service can be a vigorous competitor to incumbents and still hold sufficient market power to face ex ante obligations.
The trend: EU digital regulation is moving toward court-tested, service-level gatekeeping rules that assess platform power alongside—not instead of—competitive rivalry.
