What happened, and why it matters

Having settled the urgent question by undertaking in 2024, the Irish authority came back to the substantive one and opened a statutory inquiry into whether X lawfully processed the public posts of European users to train the Grok models. This is the inquiry that reaches the merits: not whether an impact assessment was filed, but whether there was ever a valid legal basis for using a platform's user generated content as model training data by default. Ireland is the lead supervisory authority for X, so the outcome binds through the Article 60 cooperation procedure across the Union rather than in one member state. The stakes are not confined to one platform. Almost every large platform that also ships a model has the same architecture and the same defence, and a finding either way sets the European position on the largest single source of training data in existence. As of the last verification date the inquiry is open, with no draft decision published. The AI Act does not answer this question either: Article 53 makes a provider document and summarise its training data, and says nothing about whether the underlying collection was lawful.

At a glance

The four things to take away

  • Statutory inquiry announced 11 April 2025 under section 110 of the Data Protection Act 2018.
  • Scope: the lawfulness of processing public posts of EU and EEA users to train the Grok models.
  • Ireland is lead supervisory authority, so any decision runs through the Article 60 procedure.
  • No decision, finding or fine published as of 20 August 2026.
