Construction begins on Vantage’s Lighthouse AI campus

A physical construction stage

A contractor's December 18, 2025 account and contemporary reporting confirm that Lighthouse entered construction during December. The accessible records support the month, rather than a precise first site-work day. This event records actual construction following the earlier October location announcement. [1][2][3]

The project involved a Vantage-developed campus for Oracle and OpenAI's Stargate expansion. The announced budget above $15 billion described a developer investment, while nearly a gigawatt of capacity and expected 2028 completion were future stages, not live compute or an identical customer purchase amount.
