Public company pages
A company’s build-out in one place: every campus we watch for it, the stage each is at and the capacity it states. The construction reading behind each one, and the records, are for accounts.

Nebius
An AI cloud building its own campuses in the US and Europe, two of them over a gigawatt, and renting capacity from colocation hosts. Of the 21 sites we track for it, it owns six: Independence in Missouri, Highridge in Pennsylvania, Birmingham in Alabama, Mäntsälä and Lappeenranta in Finland, and Béthune in France. At the rest it is a tenant, from DataOne's Vineland campus in New Jersey to Verne in Iceland and Mega DC in Israel.

CoreWeave
An AI cloud that mostly rents its data centers. Of the 37 sites we track for it, it owns one, a joint venture in Kenilworth, New Jersey; at the rest it is a tenant, from Core Scientific's former bitcoin-mining sites to Galaxy's Helios campus in West Texas. CoreWeave itself reported 51 data centers and more than 1.5 GW of active power as of 30 June 2026.

IREN
A former bitcoin miner turning its own grid-connected sites into AI data centers. It owns every site we track for it, from Childress in Texas, where Microsoft and NVIDIA have contracted capacity, to British Columbia, South Australia and Spain. Four more Spanish sites most likely came with Nostrum, the developer it bought in June, though IREN has not named them. IREN reported more than 5 GW of grid-connected power across North America, Europe and Asia-Pacific in October 2026.

Tesla & SpaceXAI
Elon Musk's two listed companies building AI compute: SpaceX, which runs xAI's clusters as SpaceXAI, and Tesla, which trains its driving and robot models on its own. We watch the Memphis and Southaven complex, Tesla's Cortex in Austin, a colocated cluster in Atlanta and the land SpaceX took near the Port of Brownsville, whose use it has not stated. SpaceX reported 1.7 GW of nameplate compute at 30 September 2026; Tesla plans 400 MW of training compute by the end of the year.
