Net Absorption

Net absorption is a commercial real estate metric, adapted from office and industrial markets, that measures the net change in leased or contracted data center capacity — usually expressed in MW of IT load — within a given market over a defined period, tracking realized demand rather than announced supply. Brokerages such as CBRE, JLL, and Cushman & Wakefield publish it alongside vacancy rate and under-construction pipeline in their regular data center market reports for hubs like Northern Virginia, Singapore, and Tokyo, where it is used to gauge whether new supply is being absorbed by tenants as fast as developers are building it. Strongly positive net absorption alongside falling vacancy signals a landlord-favorable market and typically precedes rising colocation and wholesale pricing, while negative or flat absorption during a large construction pipeline signals oversupply risk.
