Our 2025–2026 index 

The data centre market is entering a new era, driven by the explosive growth of artificial intelligence (AI) and surging global demand. 

In today’s fast-changing world, understanding the costs of data centre construction is more critical than ever. This helps businesses stay competitive, agile and future-ready. 

Now in its ninth year, the Data centre construction cost index 2025-2026 remains the industry’s only cost index focused exclusively on construction. It offers unmatched global insights to help businesses navigate this high-growth sector. 

Why this index matters 

As AI moves to centre stage, data centres are under greater scrutiny and facing more complex delivery challenges. Yet optimism remains strong: 73 percent of industry leaders still view the sector as recession-proof. 

This year’s report draws on a global survey of 250 experts. It covers 52 markets, providing a broader view of construction costs across both established and emerging hubs. It includes an index ranking and indicative US Dollar per watt (US$/W) benchmarks to support smarter investment decisions. 

The report includes expert insights on the most pressing issues facing the industry, from power availability and cooling innovation to alternative delivery models and supply chain resilience. 

2025 is an inflection point. The winners will be those who build boldly, mitigate risk and adapt to the demands of AI infrastructure.
