Microsoft Plans to Nearly Triple Data Centre Capacity to 38 Gigawatts by 2032
Only about 2 gigawatts of Microsoft's current 12-gigawatt footprint is built around AI-specific chips, a share Bloomberg reports will climb to roughly a third of the planned 38 gigawatts as the company extends lease terms to 25 years to soften the reported hit to capital expenditure.
Microsoft intends to expand its data centre capacity to about 38 gigawatts by 2032, more than tripling its current footprint, according to people familiar with the matter cited by Bloomberg News on Thursday. The company did not immediately respond to a request for comment.
The composition of that buildout matters as much as the headline number. Bloomberg reported that only around 2 gigawatts of Microsoft's existing 12-gigawatt capacity is dedicated to AI-specific chips, with the remainder serving traditional cloud workloads. By the time the expansion is complete, AI-focused capacity is expected to account for about a third of the 38 gigawatts, a shift that implies roughly 12 gigawatts of accelerator-dense infrastructure in the pipeline.
The spending trajectory is steep. Microsoft expects capital expenditures of $50 billion for the fiscal first quarter of 2027 and $175 billion for the calendar year 2026. The company is also spreading long-term data centre leases over 25 years rather than 15, a change that lowers annual reported capital expenditure without reducing the underlying commitments. In July, Microsoft forecast stronger-than-expected cloud growth, offering evidence that its AI investments are beginning to generate returns and easing investor concerns that the spending could outrun demand.
The scale of the 38-gigawatt plan places Microsoft among the largest private infrastructure developers in the world, comparable in electricity terms to dozens of large power plants. It also intensifies the competition for land, power interconnection, and construction labour that has already driven hyperscalers toward greenfield sites far from major cities in the United States and Europe.
BuiltWorld AI Operational Take: The lease extension from 15 to 25 years is the detail worth watching. It signals that Microsoft expects these assets to remain economically productive for decades, which in turn raises the stakes on site selection and power procurement. A campus built around today's accelerator architecture has to be designed for retrofits across multiple chip generations, because a 25-year lease on a facility that cannot accommodate newer silicon becomes a stranded asset. Project teams should be treating power capacity, cooling flexibility, and structural loading as long-horizon design constraints rather than generational specs.
