Microsoft announced a 45 billion dollar increase to its AI infrastructure budget on July 21 2026 bringing the 2027 total to 95 billion dollars. The funds will build 12 new data center campuses in Texas and Arizona with 180 thousand additional GPUs. Azure AI revenue grew 78 percent year-over-year reaching 14.2 billion dollars in Q2 2026.
The expansion includes direct liquid cooling for next-generation NVIDIA and AMD chips. Microsoft also signed a 3.8 billion dollar deal with Constellation Energy to restart the Three Mile Island nuclear plant for dedicated power. The company expects AI workloads to represent 42 percent of Azure revenue by 2028.
CEO Satya Nadella cited customer demand for OpenAI models and internal Copilot features as the driver. Microsoft has now committed over 200 billion dollars to AI infrastructure since 2023. The new sites will come online between March and November 2027.
Analysts raised 2027 revenue estimates by 9 percent following the announcement. The company will report detailed capex figures in its July 23 earnings call.
Why this matters
The spending signals Microsoft belief that AI demand remains far from saturated. Power and land constraints are becoming the primary bottlenecks for hyperscalers.
Utilities and chipmakers benefit from the multi-year visibility. Smaller cloud providers may struggle to match the scale of investment.
Microsoft position as OpenAI exclusive cloud partner is reinforced. The industry will watch whether returns on this capex meet expectations by 2028.
