Data center capacity owned and operated exclusively by hyperscalers, also known as self-builds, in Europe is expected to outpace the growth of colocation supply in 2026, according to CBRE.
The latest research shows hyperscaler self-build capacity across Europe is expected to reach 4.2 gigawatts this year, representing 24 percent year-on-year growth compared to 2025. This new supply will be delivered across nine European countries, marking the 17th consecutive year of double-digit expansion for the segment.
Hyperscalers are set to deliver a record level of self-build capacity this year as they expand cloud regions and support increasing volumes of equipment dedicated to artificial intelligence workloads. As of fourth quarter 2025, approximately 60 percent of Europe’s operational hyperscaler self-build capacity is located in Ireland, the Netherlands, Sweden and Belgium.
By comparison, the top 15 European colocation data center markets are expected to grow 19 per
