Elon Musk’s X faces EU probe over GDPR violations in AI training

Elon Musk’s X is facing a regulatory probe in Europe over its alleged use of public posts from EU users to train its Grok AI chatbot – an investigation that could set a precedent for how companies use publicly available data under the bloc’s privacy laws.

The Irish Data Protection Commission, in a statement, said it is examining whether X Internet Unlimited Company (XIUC), the platform’s newly renamed Irish entity, has complied with key provisions of the GDPR.

At the heart of the probe is X’s practice of sharing publicly available user data – such as posts, profiles, and interactions – with its affiliate xAI, which uses the content to train the Grok chatbot.
