A chart on r/EconomyCharts shows Microsoft is underperforming the Nasdaq 100 by its largest margin in approximately nine years, indicating a notable divergence between the tech giant's stock performance and the broader index.
Microsoft reportedly banned its own engineers from using certain AI tools, citing security concerns. The internal policy restricted employees from accessing specific AI services, according to a tweet from user Ric_RTP.

Microsoft is facing a growing cost crisis in its artificial intelligence operations. According to internal documents obtained by external researchers, the company's Copilot-for-Microsoft-365 offering—which embeds generative-AI features into Word, Excel, PowerPoint, Outlook and Teams—is proving substantially more expensive to run than the labor costs it could replace. The documents, which were reviewed by The Information and later surfaced publicly, show that Microsoft loses money on many of its Copilot customers, particularly those who are heavy users of the service.
The core problem is the underlying infrastructure cost. Each Copilot query requires a round-trip through Microsoft's Azure cloud, where a large language model (LLM) is invoked to generate a response. The compute, memory and energy needed for a single inference call are orders of magnitude higher than a traditional database lookup, and those costs accumulate rapidly when tens of millions of users are making dozens or hundreds of queries per day.
According to the leaked analysis, the average monthly cost of providing Copilot to a single "power user" (defined as someone who triggers more than 500 queries per month) is over $80—far more than the roughly $30–$45 per month that Microsoft charges for the Copilot Pro add-on license. This means that for every power user, Microsoft is subsidizing the service to the tune of $35–$50 per month.
By contrast, the same documents note that the median monthly salary for a knowledge worker in the United States is approximately $7,000. The fully loaded cost of a human employee (including benefits, payroll taxes, office space and IT support) is roughly $10,000–$12,000 per month. For certain routine tasks—such as drafting routine emails, summarizing meeting notes, or generating boilerplate document language—the documents estimate that a human worker costs between $0.10 and $0.50 per task, while the same task via Copilot costs $0.50 to $2.50 in compute and inference fees.
The documents further reveal that Microsoft's internal team had modeled several pricing scenarios to try to make the unit economics work. One proposal was to increase the Copilot license fee to $100 per user per month, but the team concluded that this would "destroy adoption" and push customers toward cheaper alternatives (such as Google's Gemini for Workspace, or open-source models running on their own hardware). Another proposal was to throttle power users by limiting the number of daily queries, but this was seen as undermining the value proposition of "unlimited AI assistance."
The findings have not been officially confirmed or denied by Microsoft. When asked for comment, a Microsoft spokesperson stated that the company "continues to optimize its AI infrastructure costs and deliver value to customers" and that "the unit economics of AI are improving rapidly as hardware and model efficiency advance."
The leaked documents generated an immediate and polarized reaction across social media platforms.
Skepticism and Accusations of FUD. On X (formerly Twitter) and Hacker News, a significant portion of commenters expressed doubt about the veracity or completeness of the leaked numbers. Some argued that the documents might be deliberately exaggerated to justify future price increases or to tamp down investor expectations. Others suggested that Microsoft may be using older, less efficient models (e.g., GPT-4 rather than GPT-4o or the newer GPT-4o mini) for its internal cost calculations, thereby overstating the problem.
Triumphalism from AI-Skeptic Voices. A vocal contingent of AI skeptics and critics of the "AI hype cycle" seized on the report as vindication. Posts on Reddit's r/technology and r/MachineLearning highlighted the irony that a trillion-dollar company cannot make its own technology cost-competitive with the human labor it aims to replace. One heavily upvoted comment on r/technology read: "We were told AI would make humans obsolete. Turns out, humans are the cheap option."
Concern from Enterprise Customers. Several IT decision-makers who posted on LinkedIn expressed concern about the sustainability of Microsoft's pricing. A CTO of a mid-sized European manufacturing firm wrote: "We rolled out Copilot to 500 users at $30/seat. If Microsoft is losing money on us, that means either prices will skyrocket or the product will be degraded. Neither is a good look for enterprise adoption." This sentiment was echoed by a Gartner analyst quoted in a follow-up article who noted that "the window for AI vendors to prove ROI is narrowing."
Defenders of Microsoft's Long-Term Strategy. A smaller group of commenters, including some AI researchers and Microsoft MVPs, argued that the cost analysis is a snapshot in time, not a permanent verdict. They pointed out that inference costs have been falling by roughly 10x per year, and that Microsoft's own investments in specialized AI silicon (the Maia 100 series) and more efficient model architectures (such as Microsoft Phi and the newly announced GPT-4o mini from OpenAI) will dramatically reduce costs within 12–24 months.
Memetic Spread. The core statistic—"AI costs more than human pay"—was quickly turned into memes. The most popular variant, shared thousands of times on LinkedIn and X, juxtaposed a screenshot of the leaked numbers with the caption: "When the robot uprising is cancelled for budget reasons." Another popular meme superimposed the numbers onto the "They're the same picture" Office meme format.
The Microsoft leak touches on a broader academic and policy debate about the real economic impact of generative AI. Several strands of research are directly relevant.
The Efficiency–Cost Paradox. A 2023 paper titled "The Cost of Intelligence: A Framework for Comparing AI and Human Labor" by researchers at the University of Oxford and MIT argued that while AI can outperform humans on narrow, well-defined tasks, its cost structure is fundamentally different. Human labor has a high fixed cost (salary, benefits) but low marginal cost per task. AI, conversely, has a low fixed cost (software licensing) but a high and variable marginal cost (compute). The Microsoft data appears to be a real-world validation of this theoretical framework.
Open-Source Alternatives and Cost Pressures. A 2024 preprint from Stanford's CRFM demonstrated that fine-tuned open-source models (such as Llama 3-70B or Mistral Large) can achieve comparable performance to GPT-4 on a wide range of enterprise document-processing tasks at roughly one-tenth the inference cost. This implies that Microsoft's pricing power is not absolute—if its per-task costs remain high, customers may gravitate toward self-hosted open-source solutions, particularly for high-volume, repetitive work. The leaked internal Microsoft document explicitly acknowledges this risk, noting that "open-source competition represents the greatest long-term threat to Copilot's unit economics."
Jevons Paradox for Compute. An influential essay by AI economist Ajay Agrawal (University of Toronto) applied Jevons Paradox to the AI sector. Jevons Paradox states that as a resource becomes more efficient, consumption of that resource can increase rather than decrease, because the lower cost makes new uses economically viable. Agrawal argued that as inference costs fall, the number of queries and the complexity of queries will grow, potentially negating cost reductions per task. The Microsoft documents, which show a small number of "power users" generating the vast majority of costs, are consistent with this dynamic: the cheapness of marginal queries encourages users to issue more of them, causing total infrastructure spend to balloon.
Labor-Market Displacement Studies. A 2024 working paper from the National Bureau of Economic Research (NBER) surveyed 1,200 US employers and found that firms adopting generative AI tools reported increasing their hiring of human workers for complementary roles (prompt engineering, output verification, workflow design) more than they reported replacing human workers. The authors speculated that this might be because the current generation of AI tools, while impressive, still requires significant human oversight, and that the cost of that oversight plus the AI tool itself is higher than just paying the human to do the task directly. This finding directly parallels the Microsoft internal analysis.
The core information about Microsoft's AI costs was first reported by The Information on July 15, 2025, in an article by journalists Aaron Holmes and Stephanie Palazzolo titled "Microsoft's AI Costs Outstrip Human Wages, Internal Documents Show." The article was based on access to a set of internal Microsoft documents—described as a "financial modeling deck" prepared by the Microsoft 365 product group for senior leadership.
The Information's piece states that the documents were "shared with The Information by a person with access to them who asked not to be named for fear of retaliation." The outlet reports that it verified the authenticity of the documents by cross-referencing figures with three current and former Microsoft employees who were familiar with the product's financials.
Key details from the documents, as reported by The Information:
Following The Information's report, several other outlets covered the story. On July 16, 2025, The Verge published a follow-up article that included an additional detail: that Microsoft's internal analysis had considered the possibility of spinning out Copilot into a separately metered service (pay-per-query) rather than a flat monthly subscription, but rejected the idea due to "customer confusion and negative press." The Verge also noted that a Microsoft spokesperson had declined to comment on the specific numbers but emphasized that "the rapid pace of inference cost reduction is central to our product roadmap."
The full internal documents have not been publicly released. However, a 12-page excerpt, consisting mostly of charts and summary tables, was posted to the anonymous document-sharing platform Scribd on July 17 under the title "M365 Copilot Financial Analysis – Confidential Draft." The uploader's identity is unknown. The excerpt has been viewed over 200,000 times as of the date of this briefing. Independent analysts have confirmed that the formatting and data design are consistent with Microsoft's internal PowerPoint templates, though they caution that the document could have been fabricated or altered.
Microsoft Corporation is a global technology company headquartered in Redmond, Washington. Founded in 1975 by Bill Gates and Paul Allen, it is, as of 2025, one of the world's most valuable publicly traded companies, with a market capitalization exceeding $3 trillion. The company's three primary business segments are: (1) Productivity and Business Processes (including Office, LinkedIn, and Dynamics), (2) Intelligent Cloud (Azure, enterprise services, and GitHub), and (3) More Personal Computing (Windows, devices, gaming including Xbox, and search including Bing).
Microsoft Copilot is the company's umbrella brand for generative-AI assistants powered by OpenAI's GPT-4 family of large language models, as well as Microsoft's own smaller models (the Phi series). The Copilot product line includes:
Pricing and Adoption. Copilot for Microsoft 365 is sold as an add-on to an existing Microsoft 365 subscription (Enterprise E3 or E5, or Business Premium). The standard published price is $30 per user per month. As of the company's Fiscal Year 2025 Q3 earnings call (April 2025), Microsoft reported that Copilot for Microsoft 365 had been adopted by "over 400,000 organizations" and "tens of millions of paid seats." CEO Satya Nadella specifically highlighted Copilot as a key driver of Microsoft 365 revenue growth.
Competitive Landscape. Microsoft competes in the enterprise AI assistant market with Google's Gemini for Google Workspace (priced at $20–$32 per user per month) and with a growing number of startups offering specialized AI writing or data-analysis tools. Additionally, the open-source ecosystem—with models like Llama 3, Mistral, and DBRX, served through platforms like Hugging Face, Replicate, and together.ai—represents an increasingly viable alternative for organizations with in-house AI/ML talent. Microsoft's Azure OpenAI Service also offers direct API access to GPT-4 for custom-built applications, which can be substantially cheaper per query than the bundled Copilot experience if the customer optimizes prompt lengths and caching strategies.
The leaked Microsoft documents, if authentic, provide the most detailed and sobering look yet at the raw unit economics of large-scale generative AI deployment in an enterprise setting. Several key conclusions emerge.
1. The cost problem is structural, not just a pricing issue. The fact that a single power user costs Microsoft $80+ per month—nearly three times the $30 license fee—indicates that the underlying inference cost is not a rounding error. Even if Microsoft aggressively negotiates compute prices with its own Azure division (or uses custom AI chips like Maia), the math is unforgiving: a single query to a frontier-grade LLM consumes enough GPU time (roughly 2–5 seconds on an A100 or H100) that the marginal cost adds up fast across thousands of users performing thousands of tasks. Unless there is a step-change reduction in inference cost—via model distillation, quantization, speculative decoding, or a shift to far more efficient hardware—the product will remain loss-making at its current price point.
2. The human "floor" is lower than many AI proponents assumed. A key narrative of the AI boom has been that AI will make human labor obsolete in many knowledge-work categories. The Microsoft data suggests the opposite: for many routine tasks, a human—paid $50,000–$80,000 per year—is still cheaper per task than an AI assistant. This is not an argument against AI's long-term potential, but it is a serious empirical challenge to the near-term "AI will replace everyone" thesis. It also raises uncomfortable questions for the venture capital thesis that has poured hundreds of billions into AI infrastructure: if the most powerful company in the space cannot make the unit economics work, less well-capitalized startups will face an even steeper hill.
3. Microsoft has several levers to pull, but each carries risk. The company could raise prices (risking customer defection), throttle usage (undermining the product's value proposition), or invest in dramatically cheaper inference (a technological gamble that may take 1–3 years to pay off). It could also change the underlying model—for example, routing simpler queries to a small, fast model like Phi-3-mini and only escalating complex tasks to GPT-4—which would dramatically reduce average cost per query. The fact that the leaked deck reportedly included a "Path to Profitability" section suggests that Microsoft's leadership is acutely aware of the problem and is actively modeling solutions. However, the window for action is narrowing: enterprise customers have long procurement cycles and are already evaluating alternatives.
4. The open-source threat is real and growing. The Microsoft documents' acknowledgment that open-source models are "the greatest long-term threat" is significant. If a company can achieve 85% of the quality of GPT-4 at 10% of the inference cost using a fine-tuned Llama 3 model running on its own GPU cluster (or even rented spot instances), then the value of a $30/seat branded Copilot add-on becomes questionable. Microsoft's own Azure OpenAI Service—which offers GPT-4 at $0.03 per 1,000 input tokens and $0.06 per 1,000 output tokens—is already cheaper than the bundled Copilot for high-volume customers, which further undermines the Copilot pricing story.
5. Implications for the broader AI industry. Microsoft is not alone in facing these economics. Google, Amazon (with its Bedrock and Q services), and a host of AI-native startups are all grappling with the same fundamental arithmetic. The coming 12–18 months will likely see a wave of "AI cost rationalization" as companies either (a) raise prices, (b) find significant efficiency gains through model selection and caching, or (c) rethink the all-in-one assistant model in favor of more narrowly scoped, task-specific AI tools that can be run on cheaper, smaller models. The Microsoft leak may well be remembered as the moment the AI industry's "growth-at-all-costs" phase gave way to a more sober period of margin discipline and ROI scrutiny.
In summary, the Microsoft internal documents reveal a fundamental tension at the heart of the current AI wave: the technology is powerful, but it is also expensive. For AI to fulfill its promise of transforming enterprise productivity, it must first pass a basic economic test—and on that test, the evidence from Microsoft's own analysis is, at best, mixed.
