Europe’s data center construction market is projected to grow from $16.3B in 2024 to $27.9B by 2033, driven by cloud adoption, AI workloads, and sustainability mandates. As highlighted in recent TheMarketAI coverage of SWI Group and Nebius, Europe’s buildout is increasingly defined by energy efficiency, sovereign infrastructure, and long-term resilience rather than pure scale.

Amsterdam-based Nebius is emerging as one of the fastest-growing players in AI infrastructure, combining custom hardware, vertically integrated data centers, and sustainability leadership. With 270% stock growth since its 2024 IPO and a market cap of $12.65B, Nebius is betting that building everything—from servers to cloud APIs—in-house will outmaneuver hyperscalers and cloud resellers in the AI arms race.
