March 2026 brought a wave of major data center transactions and expansions across North America and Europe. AMD announced a $100 billion agreement to supply up to 6 GW of AI capacity to Meta, while Microsoft secured approval for 15 new data centers at the former Foxconn site in Mount Pleasant, Wisconsin, with a taxable construction value exceeding $13 billion. Meta broke ground on a 1 GW, $10 billion campus in Lebanon, Indiana, and Equinix and Canada Pension Plan Investment Board acquired Iceland-based atNorth from Partners Group for $4 billion. In Europe, the European Data Centre Association's 2026 State of European Data Centers report forecasts cumulative investment of 176 billion euros between 2026 and 2031, warning that grid readiness rather than capital will constrain future capacity growth.
The scale of individual transactions, including a $100 billion AMD-Meta compute agreement and a $40 billion acquisition of Aligned Data Centers, reflects how rapidly capital concentration in AI infrastructure is accelerating. The European industry forecast warning that grid readiness will be the binding constraint on capacity through 2031 parallels pressures emerging in North America, pointing to a shared bottleneck that could slow deployment timelines across multiple major markets.
