Microsoft Confirms $10 Billion AI Data Center Park in Sines, Portugal

Overview

• Microsoft president Brad Smith disclosed the plan at Web Summit in Lisbon, and a company spokesperson confirmed the $10 billion figure.
• The project will be developed with Portuguese builder Start Campus and UK-based Nscale at a data center park in Sines.
• Start Campus said the investment aligns with ongoing negotiations for the next development phase after opening the first of six planned buildings in March.
• Press reports say the site is expected to host about 12,600 next‑generation Nvidia chips, with the location benefiting from renewable power options and major submarine cable links.
• Microsoft previously signed a multi‑year lease for Sines capacity in October as part of a broader push that includes recent deals with neocloud providers CoreWeave and Nebius and plans to lease Nscale capacity in Norway and the UK.
