Microsoft will report fiscal third-quarter earnings on Wednesday with a disclosed Azure commercial backlog of $620 billion, a 47% jump from the prior quarter and the largest forward-revenue commitment in cloud-computing history. The figure dwarfs Amazon Web Services' most recent backlog disclosure of $362 billion and Google Cloud's $128 billion.
The growth reflects multi-year AI infrastructure deals signed with Anthropic competitors, OpenAI workloads scaling beyond GPT-5, and Fortune 500 enterprises consolidating workloads on Azure as Copilot adoption tops 70% of the largest U.S. firms. Microsoft does not publish a specific AI revenue line, but Wall Street analysts estimate AI-related Azure revenue is now running at a $42 billion annualized rate.
Capex Discipline Versus the Build-Out Race
The bull case rests on Microsoft's ability to convert backlog into recognized revenue while keeping capital expenditures from outrunning gross margins. Azure capex guidance for the current fiscal year stands at approximately $128 billion, with management telegraphing further increases through fiscal 2027 as the company brings online new data center campuses in Wisconsin, Spain and Indonesia.
Bernstein analyst Mark Moerdler raised his price target to $620 last week, arguing that Azure's gross margin trajectory is improving despite the capex ramp because new GPU clusters are arriving with better power efficiency and Microsoft is increasingly using its in-house Cobalt and Maia silicon for non-training workloads. The stock closed Friday at $562.30.
What to Watch Wednesday
Investors will focus on three numbers: Azure revenue growth (consensus 38%), capital expenditures for the June quarter (consensus $35 billion), and any disclosure on the OpenAI revenue-sharing arrangement. CEO Satya Nadella has previously hinted that the relationship will evolve as OpenAI seeks more compute diversification, a topic likely to come up on the earnings call.
Options markets are implying a 4.8% post-earnings move, with skewed positioning suggesting traders are bracing for a beat-and-raise quarter. Microsoft has exceeded EPS estimates in 14 of the past 16 quarters, and revenue has come in above consensus in 15 of those reports.
