The Economics of the AI Boom
Part 1: Real Demand or a Financial Feedback Loop? …Yes
Artificial intelligence is rapidly becoming the dominant story in the stock market. NVIDIA has become one of the most valuable companies in the world. Microsoft, Amazon, Meta, Alphabet, and other technology giants are collectively spending hundreds of billions of dollars building AI infrastructure. Utility companies are expanding power generation to support data centers. Semiconductor manufacturers are racing to increase production capacity. Construction firms, cooling companies, networking suppliers, and power-grid operators are all reorganizing around expected AI demand.
To many investors, this looks like the beginning of a genuine technological revolution comparable to the internet or mobile computing. But a growing number of critics argue that parts of the AI economy may resemble a financial bubble built on circular spending, debt-fueled infrastructure expansion, and assumptions about future demand that may not materialize.
The central question is whether the current level of spending and valuation reflects sustainable long-term economics, or whether markets are extrapolating too much too quickly from an industry still in its early stages.
To understand the debate, investors first need to understand how the modern AI ecosystem actually works.
Training and operating advanced AI systems requires enormous computing power. That computing power comes primarily from specialized chips called GPUs, which are designed to handle the massive parallel calculations used in machine learning. NVIDIA dominates this market, and companies building AI systems often need tens or even hundreds of thousands of GPUs at a time.
These systems are extraordinarily expensive. A single advanced AI server can cost hundreds of thousands of dollars. Entire AI data centers can cost billions. On top of the hardware expense, these facilities consume enormous amounts of electricity and require sophisticated cooling systems because the chips generate tremendous heat.
As a result, the AI boom is a massive industrial and financial buildout involving semiconductors, utilities, construction, power grids, cooling systems, networking equipment, and enormous amounts of capital.
Critics’ Concerns
One of the most important concepts in the debate about the AI boom’s financing models is “Remaining Performance Obligations,” or RPO. This accounting term refers to future contracted revenue companies expect to receive over time under signed agreements.
When investors see rapidly growing RPO, they often interpret it as proof of strong future demand. If a cloud company reports tens or hundreds of billions of dollars in future commitments, the market assumes customers expect to use enormous amounts of AI infrastructure in the future.
But investors may not fully appreciate how concentrated and interconnected some of this spending has become.
A simplified version of the concern looks something like this:
Microsoft invests heavily in OpenAI and provides it with massive cloud computing resources through Azure. OpenAI, in turn, spends enormous amounts of money on Microsoft’s cloud infrastructure. Microsoft then reports strong AI cloud growth and rising future contract obligations, while Microsoft and other hyperscalers use that demand to justify buying huge quantities of NVIDIA GPUs.
An important part of this cycle is being financed by capital spending, debt financing, strategic investments, and long-term contractual commitments tied to expectations about future AI growth. Parts of the AI ecosystem may currently depend as much on continued access to financing and investor confidence as on fully developed commercial demand.
At the same time, newer specialized AI cloud companies — often called “neoclouds” — are borrowing heavily to build GPU clusters. These companies purchase large quantities of NVIDIA hardware, often financed through debt backed by future contracts, and then rent access to those GPUs to AI developers and enterprise customers.
As more contracts are signed, these companies can raise additional financing, allowing them to buy even more GPUs and expand further.
This resembles a financial feedback loop. Revenue growth at one company may depend heavily on spending by another company that is itself relying on debt financing, investor capital, or future demand assumptions. A large portion of the ecosystem may therefore be selling infrastructure and services to other participants within the same AI buildout cycle.
The contracts, the infrastructure, and the money being spent are all real. But whether ultimate end-user demand will prove large and profitable enough to justify the scale of the current buildout remains uncertain.
Imagine a gold rush where companies selling shovels, trucks, generators, and mining equipment are all experiencing explosive revenue growth because everyone expects enormous future profits from mining operations. Those suppliers may genuinely report booming sales. But if the underlying mining economics later disappoint, the entire ecosystem can become unstable because the spending was based on overly optimistic expectations.
The risks become even larger if the equipment manufacturers borrowed heavily to expand production capacity. If sales growth later slows while debt payments, operating costs, and expansion bills continue coming due, companies that appeared financially strong can suddenly find themselves under pressure.
Parts of today’s AI economy contain similar characteristics.
Financing of the AI Infrastructure Buildout
Several specialized AI cloud firms, such as CoreWeave and Nebius, have raised massive amounts of debt and investment capital backed by GPUs and future contracts. In theory, this is not irrational. Infrastructure industries have often required enormous upfront investment before becoming broadly profitable, including railroads, telecom networks, electric utilities, and internet infrastructure.
The bullish argument is that AI is following the same historical pattern: infrastructure must be built before mass adoption can occur. Supporters of the AI boom argue that cloud computing also looked excessively expensive in its early years, yet ultimately became one of the most profitable industries in the world.
From this perspective, large losses and heavy capital spending are not necessarily signs of a flawed business model. They may simply reflect the early stages of building a transformational technology platform.
The bearish argument, however, is that the current AI cycle may be moving too quickly, using too much leverage, and building too much infrastructure around future demand that may not fully materialize.
Some AI infrastructure companies are carrying enormous debt loads while depending on a relatively small number of major customers. If those customers reduce spending, delay projects, or fail to generate profitable businesses from AI services, the financial assumptions supporting the entire infrastructure expansion could weaken quickly.
This is one reason some analysts compare the current AI boom to the dot-com bubble. Even though the internet became far more important than many investors imagined, investors overestimated how quickly profits would emerge and underestimated how much overbuilding and financial failure would occur along the way. During the telecom boom, companies borrowed enormous sums to build fiber-optic networks because future internet demand appeared limitless. In the long run, the world did need massive internet infrastructure, but many companies built too much capacity and accumulated unsustainable debt before profitable demand fully arrived. A large number of firms collapsed even though the underlying technological trend was real.
AI infrastructure could face similar risks if future demand or profitability fails to develop as quickly as current spending assumes. While AI could transform software development, research, medicine, logistics, finance, defense, and many other industries, that does not mean every company participating in today’s buildout will justify its valuation, survive financially, or generate adequate returns on capital.
At the same time, we should avoid overstating the bearish case. AI usage is already expanding rapidly across software development, search, advertising, customer service, cybersecurity, scientific research, and enterprise automation. Large corporations are spending real money on AI capabilities.
NVIDIA’s profits are not hypothetical. The company is generating extraordinary cash flow and margins today because demand for GPUs is currently overwhelming supply.
History shows that transformative technologies can simultaneously change the world while still producing bubbles, overbuilding, speculative excess, and disappointing investment returns for many participants along the way.
The central question is whether the current AI economy is developing into a profitable, self-sustaining commercial ecosystem, or whether too much of today’s growth still depends on a relatively small group of companies financing one another’s expansion while investors expect future demand to eventually justify the buildout costs.
The answer may determine not only the future of AI stocks, but also the future direction of the broader market. Much of today’s market leadership has become increasingly concentrated in AI-related companies, while many other sectors have lagged behind. If AI spending ultimately proves more durable and profitable than skeptics expect, the current buildout could reshape large portions of the economy. But if parts of the AI boom prove overextended, the effects could ripple far beyond technology stocks alone — a subject we will examine further.
Final Note
This article is the starting point for a broader series examining the economics, infrastructure, financing, and market implications of the AI boom and its growing influence across the economy and financial markets.
The goal is to understand how the AI infrastructure ecosystem works, where real economic value is being created, where risks may be accumulating, and which companies may ultimately benefit — or suffer — as the AI economy develops.
