Microsoft Announces $10 Billion Expansion of AI Infrastructure in Portugal

• $10B Investment Announced at Web Summit 2025

  Brad Smith, President of Microsoft, announced the company’s $10 billion commitment during the Web Summit in Lisbon. This investment strengthens AI infrastructure in Portugal, marking the company’s largest project in the country to date and one of its largest AI-focused expansions in Europe. It aligns with Microsoft’s goal to more than double European data-centre capacity under its Digital Commitment to Europe, launched in April 2025.

• Sines Data Centre to Host 12,600 Nvidia GPUs

  The project accelerates the development of the Sines Data Centre hub, built with Start Campus, Nscale, and Nvidia. The hub will deploy 12,600 next-generation Nvidia GPUs, setting a European benchmark for scalable AI systems. This GPU deployment further embeds AI infrastructure in Portugal as a regional priority. Start Campus previously announced €8.5 billion in investments by 2030 to meet hyperscale demand.

• Largest AI Compute Investments in Europe

  Microsoft described the initiative as “one of the largest investments in AI computing capacity in Europe.” The project sits within a global wave of accelerated data-centre expansion triggered by the rise of large AI workloads since 2022, when ChatGPT’s release drove industry-wide demand for compute. The Sines project complements new Microsoft–Nscale collaborations in Texas, the UK, and Norway, as well as a $15 billion AI investment in the United Arab Emirates announced on 3 November 2025.

• Portugal’s Government Push for AI Gigafactories

  Gonçalo Matias, Deputy Minister for State Reform, said the government is targeting over €16 billion in AI gigafactory investments. He reaffirmed Portugal’s focus on scaling AI infrastructure in Portugal through collaboration with the European Commission, aiming to establish a flagship AI gigafactory in Sines.

• €4B Public–Private Gigafactory Proposal Under EU Review

  The Sines gigafactory proposal, led by Banco Português de Fomento, is currently under evaluation by the European Commission. If approved, the project would involve around €4 billion in public and private funding and would be co-located alongside the hyperscale data-centre developments Microsoft is accelerating.

• AI Expected to Add €2.3 Trillion to EU Economy by 2030

  Matias highlighted AI’s projected €2.3 trillion contribution to the EU economy by 2030. Portugal’s Atlantic position—anchored by subsea cable routes linking Europe, Africa, and the Americas—creates a natural foundation for expanding AI infrastructure in Portugal, strengthened by the country’s green-energy projects designed to power energy-intensive compute facilities.

• National Strategy for Data Centres and Sovereign Cloud

  Portugal’s wider national plan incorporates development of a sovereign cloud to strengthen digital autonomy, trust, and security. The country anticipates “tens of billions” in data-centre-related investments, leveraging Lisbon’s status as one of the world’s most connected transcontinental cities and its established academic and innovation ecosystems.

• Additional Microsoft Initiatives Supporting National Upskilling

  Microsoft is also advancing skills programs. Through the Skills for Jobs initiative with LinkedIn, the company seeks to prepare the workforce for AI-driven economies. Its participation in the AI Innovation Factory—with Accenture, Avanade, and Unicorn Factory Lisbon—supports governance, solution scaling, and responsible AI adoption.

Why This Matters

Microsoft’s investment solidifies AI infrastructure in Portugal as a strategic European asset. It accelerates regional access to GPU capacity, sovereign cloud systems, and advanced compute architecture, attracting additional public–private capital. The Sines hub reinforces Portugal’s position within Europe’s emerging AI ecosystem and strengthens long-term digital sovereignty priorities.
