“We're calling the first one Prometheus and it's coming online in '26. We're also building Hyperion, which will be able to scale up to 5GW over several years. We're building multiple more titan clusters as well. Just one of these covers a significant part of the footprint of Manhattan.”

Prometheus is under construction at Meta's New Albany, Ohio campus (gas turbines plus nuclear supply deals signed with Vistra, TerraPower and Oklo in January 2026); Meta still says it expects the cluster online sometime in 2026, so the claim cannot be resolved before 31 December 2026.
