The European Commission said on Monday that it has launched a new formal investigation against X under the Digital Services Act.

The new investigation will assess whether the company properly assessed and mitigated risks associated with the deployment of Grok's functionalities into X in the EU, the commission said.

"Separately, the Commission has extended its ongoing formal proceedings opened against X in December 2023 to establish whether X has properly assessed and mitigated all systemic risks, as defined in the DSA, associated with its recommender systems, including the impact of its recently announced switch to a Grok-based recommender system," it added in a statement.
