The council adopts a legislative act amending the EuroHPC Regulation (2021/1173) to legally permit the Union to invest in AI Gigafactories and quantum pillars. It formalizes the “majority ownership” rule for AI Gigafactory consortia and excludes “high-risk vendors” from the supply chains of these facilities. It creates the legal basis for the EU to own a share of the computing time, which is then redistributed to European startups.
