TikTok filed a request with the European Union’s top court on Tuesday to overturn its designation as a gatekeeper under the Digital Markets Act [1, 2].

The legal challenge targets the core of the EU's regulatory framework for big tech. If successful, TikTok could avoid the strict obligations and oversight imposed on companies deemed to have dominant control over digital ecosystems.

The request was submitted to the Court of Justice of the European Union on May 12 [1]. The platform, owned by ByteDance, is contesting the claim by EU regulators that its services create a digital lock-in for consumers [1, 2].

TikTok said that users can freely switch between competing applications [1, 2]. This argument directly challenges the criteria used by the EU to identify gatekeepers, which are firms that provide a core platform service and act as an important gateway for business users to reach end users.

Under the Digital Markets Act, gatekeepers must adhere to a set of rules designed to ensure contestability, and fairness in digital markets. These rules include requirements for interoperability and restrictions on how companies can prefer their own services over those of rivals.

By challenging this status, TikTok aims to remove the regulatory burden that comes with the gatekeeper label. The company said that the current designation does not accurately reflect the competitive nature of the short-form video and social media market [1, 2].

This legal move represents a significant test of the Digital Markets Act's enforcement. If the court rules in favor of TikTok, it could set a precedent for other tech firms to challenge their gatekeeper status, potentially weakening the EU's ability to regulate dominant digital platforms and reduce the effectiveness of the DMA's anti-monopoly goals.
