SpaceX has disclosed plans to make major changes to how it builds AI data centers, a shift that could slow the expansion pace for new data center campuses. Musk recently assigned a group of rocket engineers to oversee data center construction, sources familiar with the matter said. The new team has adopted a more cautious construction approach, contrasting with Musk’s earlier emphasis on moving quickly. The change may extend timelines for new campuses after Musk built AI business data centers at record speed two years ago.
