## Overview The Court of Justice of the European Union (CJEU) issued rulings in October 2026 affirming large platform designations under the EU's Digital Services Act (DSA) and Digital Markets Act (DMA). The EU General Court upheld obligations on online adult entertainment platform Stripchat, while CJEU Advocate General Biondi recommended dismissing TikTok's challenge to its "gatekeeper" designation under the DMA (IPWatchdog, October 19 and October 16). ## Why It Matters These rulings reinforce the EU's regulatory authority to designate major digital platforms — regardless of sector, including adult content platforms — as subject to heightened obligations under the DSA and DMA. For companies like TikTok, gatekeeper status triggers significant compliance obligations around interoperability, data use, and anti-self-preferencing rules. The rulings suggest EU courts are likely to continue backing the European Commission's designation decisions against industry challenges. ## Key Entities - **TikTok**: Challenged its DMA gatekeeper designation; AG Biondi recommended dismissal of the challenge. - **Stripchat**: Online adult entertainment platform whose DSA large-platform obligations were upheld by the EU General Court. - **CJEU**: Court of Justice of the European Union, including its General Court and Advocates General. ## What to Watch - The CJEU's final ruling on TikTok's gatekeeper challenge, following AG Biondi's opinion. - Additional platforms potentially designated or challenging designations under DSA/DMA. - Enforcement actions stemming from upheld designations.
