Microsoft reported strong quarterly results with $77.7 billion in revenue and 40% Azure growth, but shares fell 3% as the company revealed record $35 billion AI infrastructure spending and plans to double data center capacity within two years.

Record Infrastructure Investment Drives Growth

Microsoft reported exceptional quarterly results for the three months ending September 30, with revenue climbing 18% to $77.7 billion and operating income surging 24% to $38 billion

However, what truly defined this quarter was Microsoft's unprecedented capital expenditure of $34.9 billion, representing a staggering 74% increase from the same period last year

. This record spending was primarily allocated to AI and cloud infrastructure, with nearly half dedicated to computer chips and much of the remainder focused on data center real estate

Ambitious Expansion Plans Despite Market Concerns

During Wednesday's earnings call, CEO Satya Nadella announced Microsoft's ambitious plan to double its data center footprint over the next two years

. The company also committed to boosting its AI capacity by more than 80% this year, underscoring the massive scale of investment required to maintain competitiveness in the AI race.

Despite these impressive financial results and growth projections, Microsoft's stock fell more than 3% in after-hours trading

. Investors expressed concerns about the sustainability of such massive spending levels and the physical constraints now limiting the company's growth. Chief Financial Officer Amy Hood confirmed that capital expenditure growth would continue throughout fiscal 2026 at an even higher rate than the previous year

OpenAI Partnership Evolution and Financial Impact

The earnings report coincided with significant developments in Microsoft's relationship with OpenAI. The companies announced a restructured partnership that gives Microsoft approximately a 27% stake in OpenAI's new for-profit entity, valued at roughly $135 billion

1

. Under the new agreement, Microsoft retains commercial rights to OpenAI products through 2032, while OpenAI committed to purchasing $250 billion in computing power from Microsoft over the coming years.

This partnership restructuring had immediate financial implications, with Microsoft reporting a $3.1 billion drop in net income due to what it termed an "equity method investment" in OpenAI, resulting in a 41-cents-per-share hit to earnings

5

. Despite this impact, the company's bottom line remained robust at $27.7 billion.

Infrastructure Constraints Challenge Growth

Analysts noted a fundamental shift in Microsoft's business model, from a software company that scaled through code to one constrained by physical infrastructure. The company warned investors that it would remain "capacity-constrained through the end of the fiscal year"

This transformation was symbolically reinforced by an Azure outage that occurred hours before the earnings announcement, triggered by an "inadvertent configuration change"

. The incident served as a reminder of the infrastructure challenges facing even the most well-resourced technology companies as they scale AI operations.

Microsoft's commercial productivity segment, including Office applications and the AI assistant Copilot, generated $33 billion in revenue, up 17% from the previous year

1

. The company's personal computing division saw more modest growth of 4%, reaching $13.8 billion in sales, partly driven by increased PC laptop demand ahead of anticipated tariff implementations.
