Maia, its own inference silicon arriving in 2027, is the bet to bend that cost curve before Wednesday's fiscal Q1 print. [Microsoft](https://theinference.org/markets/companies/microsoft) reports fiscal Q1 on Wednesday, and the number that will decide how the print is read is not revenue [1]. It is capital spending, [which hit $41 billion in the June quarter](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0000789019), more than the $35.8 billion Microsoft earned in net income that quarter [1]. Two-thirds of that bill went to short-lived chips and servers, much of it [Nvidia](https://theinference.org/markets/companies/nvidia) silicon that wears out in a few years [1]. Microsoft is building its own Maia chips to take the highest-volume slice of that work, inference, in-house. Wednesday is when investors judge whether the spend is strategy or a hole. *Chart: **Microsoft's capex has caught up with its quarterly net income** Column chart of Microsoft quarterly capex versus net income across eight quarters, capex rising to meet and exceed net income by mid-2026.* *Microsoft's capex has caught up with its quarterly net income [1][4]* ## Inference is where Microsoft's bill compounds Inference is the cheap-to-describe, expensive-to-run part of AI. Every Copilot answer, every GitHub coding suggestion, every dispatched agent is a billable query against a GPU. Microsoft runs those millions of times a day, so modest efficiency gains compound at scale [1]. Maia 300, due in production deployments in 2027, is [claimed at seven times Maia 200's rack output and 40% more AI per megawatt](https://finance.yahoo.com/technology/ai/articles/microsoft-wants-keep-more-ai-140700046.html) than top GPUs [1]. If even the inference claims hold, Microsoft bends its own cost curve without waiting for Nvidia to cut prices. ## It does not need to beat Nvidia everywhere The honest counterweight: Bloomberg Intelligence's Mandeep Singh calls Microsoft's silicon "nowhere close" to Nvidia's or Google's [1]. But Microsoft does not need to beat Nvidia everywhere. It needs Maia to handle the repetitive Copilot and agent workloads it pays for millions of times a day, while Nvidia keeps the frontier training business. Google's TPUs show this playbook works; Microsoft is years behind where [Alphabet](https://theinference.org/markets/companies/alphabet) is. ## Cheaper serving decides who keeps the AI boom's margin The chain from chip to your workday runs through who can afford to serve AI at scale. Cheaper inference means Copilot seats get priced for company-wide rollout, which is what enterprise buyers were finally doing last quarter, [adding tens of thousands of seats at a time](https://fundaai.substack.com/p/previewmsft-fy1q27-gpt-56-improves) [3]. The bottleneck has moved from model quality to serving cost. Whoever closes that link, Microsoft or Nvidia, keeps the AI boom's margin. Watch Wednesday's capex guidance for which one the market thinks it is. ## Takeaway Microsoft's capex now tops its net income, and Wednesday's fiscal Q1 print will be judged on whether Maia and cheaper inference can bend the cost curve before Nvidia's bill does. ## Sources 1.
