Microsoft has announced a €8.6 billion ($10 billion) investment to build an artificial intelligence data center in Sines, Portugal, marking one of its largest investments in Europe. The project is a partnership with developer Start Campus, AI infrastructure platform Nscale, and will utilize 12,600 of Nvidia's next-generation GPUs. The investment aims to bolster Portugal's role as a key player in European AI development and is part of Microsoft's broader strategy to expand its global computing infrastructure to meet the surging demand for AI services. The announcement was made by Microsoft's President, Brad Smith, at the Web Summit in Lisbon. Initial market reaction appeared muted, with Microsoft's stock trading slightly lower following the news.
