Microsoft signs $130B in data center leases in one quarter

Microsoft ↗ 0.52% disclosed more than $130 billion in new data center leases during its fiscal fourth quarter, its largest single-quarter jump in leasing commitments by far, as the company races to build out infrastructure for artificial intelligence.

The company's total commitments for leases that have not yet commenced reached $329.1 billion as of June 30, up from $196.6 billion in the prior period, Microsoft said Wednesday in a regulatory filing. The future costs, which come on top of active leases, will not appear on the balance sheet until payments begin.bloomberg+1

AI Demand Drives Record Commitments

"That's really a signal of the continued demand strength that we see," Jonathan Neilson, Microsoft's investor relations chief, said in an interview with Bloomberg. "These leases are going to be there to serve demand for many many years."finance.yahoo

The surge follows a period in which Microsoft pulled back from leasing activity through much of 2025, canceling several data center leases amid questions about AI demand. That pause left the company constrained by capacity shortages heading into 2026. The new commitments suggest those concerns have dissipated as demand for cloud-based AI services accelerates.linkedin+1

Azure Growth Tops Estimates

The leasing news accompanied Microsoft's fiscal Q4 2026 earnings, which beat analyst expectations. Revenue reached $87.62 billion, while Azure cloud revenue grew 43% — topping the 39% to 40% growth that analysts had projected. The company's commercial remaining performance obligations, a measure of contracted future business, climbed 84% to $678 billion, up from $627 billion in the prior quarter.microsoft+3

Spending Under Scrutiny

Microsoft's infrastructure push comes as investors scrutinize whether massive AI-related capital expenditures will deliver adequate returns. The company was expected to spend roughly $35.2 billion on capital expenditure excluding capital leases in the quarter alone, more than double year-over-year levels. Shares rose in after-hours trading as the results eased concerns that spending was outpacing demand. Microsoft's Azure growth trajectory — accelerating from 33% a year ago — offered the clearest evidence yet that customer appetite for AI workloads continues to expand alongside the company's infrastructure buildout.finance.yahoo
