Delegated act on data access enters into force and unlocks access to data on large online platforms for researchers

The European Commission has announced that as of 29 October 2025, new rules under the Digital Services Act (DSA) will allow researchers to gain unprecedented access to very large online platforms' data to study the societal impact stemming from the platforms' systems. Such access is now possible following the entry into force of the delegated act on data access.

The measures will allow qualified researchers to request access to previously unavailable data from very large online platforms and search engines. Platforms' own data is a key element in understanding the possible systemic risks stemming from, for example, recommender systems. It will also help address risks such as the spread of illegal content and financial scams. Hence, ensuring a safer online experience for users, and, importantly, minors.

While creating opportunities for new studies, these measures also include safeguards to protect the companies' interest. To get access to platforms' data, researchers will have to undergo a strict assessment carried out by Digital Services Coordinators, the national authorities responsible for the implementation of the DSA. If researchers fulfil all the criteria prescribed by the law and if the research projects are relevant for studying systemic risks, including the spread of illegal content or negative effects on mental health, under the DSA, the platforms are legally required to comply with their data requests. Digital Services Coordinators are already working together to ensure that data access applications will be assessed uniformly across Member States and in due time.
