What Is a Bubble, Technically?
A bubble is when an asset's price detaches from what its underlying cash flows can justify, driven by expectations of ever-rising prices rather than fundamentals. It is not the same as "expensive" or "risky." A bubble specifically means the price and the math no longer agree, and the gap is closed by a crash, a slow deflation, or the fundamentals eventually catching up.
Economists don't have one clean formula for a bubble, but the pattern repeats: prices rise faster than earnings can plausibly justify, new money floods in chasing the trend instead of fundamentals, and skeptics get dismissed as people who "don't get it." The dot-com bubble, the 2008 housing bubble, and the 1990s telecom buildout all fit this shape. None of them meant the underlying idea was fake. The internet was real. Houses are real. Fiber optic cable is real. The bubble was in the price, not the product.
Hyperscaler AI capex is compounding fast

You can answer no to the first and yes to the second. Most of the credible voices we found in 2025 and 2026 do exactly that.
What Is the Bull Case for AI Right Now?
Enterprise AI adoption is real and accelerating, not theoretical. Over 80% of organizations have piloted tools like ChatGPT or Copilot and roughly 40% report full deployment. Anthropic's revenue went from 9 billion to 30 billion dollars annualized in four months in early 2026, and OpenAI is running near 2 billion dollars a month.
Start with usage, because usage is the hardest number to fake. According to MIT's 2025 study on enterprise AI, over 80% of organizations have piloted generative AI tools and nearly 40% report they've moved past piloting into deployment. That is not speculative interest. That is millions of people opening ChatGPT, Copilot, or Claude at work every day.
Revenue backs it up. Anthropic's annualized run-rate went from about 1 billion dollars at the end of 2024 to 9 billion at the end of 2025 to 30 billion by April 2026, with over 1,000 enterprise customers each spending more than 1 million dollars a year, according to SaaStr's reporting. OpenAI crossed 2 billion dollars in monthly revenue around the same time, near a 24 billion dollar annualized run-rate. Those aren't vaporware numbers. Real companies pay real invoices for this software every month, and the growth curve on both companies looks closer to 3x-to-10x per year than the flat line you'd expect from a fad.
Nvidia CEO Jensen Huang makes the strongest version of the bull case: this isn't speculative capital chasing a trend, it's an infrastructure buildout backing compute demand that is currently constrained, not oversupplied. "There's been a lot of talk about an AI bubble," Huang said in November 2025. "From our vantage point, we see something very different." His argument is that GPU-driven infrastructure is displacing older computing across search, ads, and data processing before agentic AI applications even fully arrive, so the demand curve is still climbing.
What Is the Bear Case Against AI Right Now?
The bear case has three legs: a revenue gap Sequoia Capital sized at roughly 600 billion dollars a year that AI companies would need in new revenue just to justify current infrastructure spending, a cluster of circular deals where the same companies fund each other's purchases, and stock gains so concentrated in a handful of names that the S&P 500 has effectively become an AI bet.
Sequoia partner David Cahn has run this math twice now. In 2023 he called it "AI's $200B Question," the gap between what GPU spending implied in future revenue and what AI companies were actually generating. By mid-2024, as capex accelerated, he updated it to "AI's $600B Question": even generous assumptions about new AI revenue from Google, Microsoft, Meta, and others still left a shortfall in the hundreds of billions. That gap has only gotten harder to close since, because capex kept climbing faster than most AI product revenue.
Then there's the money that circles back on itself. Nvidia has committed up to 100 billion dollars to help finance OpenAI's data center buildout, and OpenAI has committed to spending that money on Nvidia chips. OpenAI separately signed a roughly 300 billion dollar cloud contract with Oracle, which is spending tens of billions of that on Nvidia GPUs to fulfill it. Microsoft has put roughly 11 billion dollars into OpenAI while also selling it cloud capacity. None of this proves the underlying demand is fake. But a meaningful share of the industry's headline revenue and investment numbers are the same dollars changing hands between a small group of companies, not new money from independent customers. The chart below shows the scale.
AI's biggest deals often pay each other

Each name appears on both sides of at least one deal, so these dollars are not proof of independent customer demand. Source: The Register, November 2025, compiled from company disclosures.Finally, look at where the stock market's gains actually came from. As of mid-2026, the Magnificent Seven make up roughly a third of the entire S&P 500's value. In 2023, those seven stocks alone accounted for 62% of the index's total return. That kind of concentration means a large share of most people's retirement accounts, index funds, and 401(k)s are quietly a leveraged bet on seven companies executing an unprecedented, unproven spending plan correctly.
What Do Respected Voices on Each Side Actually Say?
The people closest to the money are the ones hedging hardest. Sam Altman, Jeff Bezos, and Jamie Dimon have all said some version of "yes, there's a bubble, and also this is real and important," while Jensen Huang and most AI lab leadership reject the bubble framing outright. Few serious voices take a pure, uncomplicated stance.
| Voice | Camp | What they actually said |
|---|---|---|
| Sam Altman, OpenAI CEO | Both | "Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes." Also called AI "the most important thing to happen in a very long time." |
| Jeff Bezos, Amazon founder | Both | Called AI an "industrial bubble" at Italian Tech Week, but said industrial bubbles are less harmful than financial ones because society keeps the winning infrastructure. |
| Jamie Dimon, JPMorgan CEO | Both | "You can't look at AI as a bubble, though some of these things may be in the bubble." Says AI overall will "pay off," like cars and TV did. |
| Jensen Huang, Nvidia CEO | Bull | "There's been a lot of talk about an AI bubble. From our vantage point, we see something very different." |
| Michael Burry, investor | Bear | Compared Nvidia to Cisco in 1999, bought over 1 billion dollars in Nvidia and Palantir puts, then deregistered his fund weeks later. |
| Torsten Slok, Apollo chief economist | Bear | Says the top 10 S&P 500 companies are more overvalued on forward P/E today than the top 10 were at the 1999 dot-com peak. |
| Aswath Damodaran, NYU finance professor | Bear (on price, not tech) | Says the industry needs "two, three, four trillion in revenues eventually" to justify current spending, and exited his Nvidia position. |
What Can the Dot-Com Bubble Teach Us About AI?
The dot-com bubble proves that a technology being real and a bubble being real are not contradictions. The internet reshaped the economy exactly as the optimists promised, and the Nasdaq still fell almost 80% between 2000 and 2002. Telecom firms overbuilt so badly that most fiber laid in the 1990s sat dark for years. AI can follow the same script.
This is the single most useful lesson in this whole debate, and people misuse it constantly. "The internet was real, so the dot-com crash didn't matter" is wrong. "The dot-com crash happened, so the internet was overhyped" is also wrong. Both things were true simultaneously: the internet went on to justify every serious prediction made about it, and Pets.com, Webvan, and hundreds of other companies still went to zero, and trillions of dollars of market value still evaporated.
Telecom capex during that era is the closer analogy to today's AI buildout than the dot-com stocks themselves. Telecom firms spent heavily on fiber optic infrastructure betting internet traffic would keep doubling every few months. It didn't grow nearly that fast, and by some estimates 85% to 95% of the fiber laid in the late 1990s sat dark for years afterward. Today's hyperscalers are making a similar bet on data centers and GPUs. The physical assets, unlike a stock price, don't disappear when sentiment turns. They just sit there depreciating until demand catches up, or doesn't.
Did the AI Bubble Already Start Popping in 2026?
Not exactly. In June 2026, the Nasdaq dropped over 4% in a single session and semiconductor stocks lost more than 1.3 trillion dollars in market value, with Microsoft and Meta briefly entering bear market territory. Most analysts called it a valuation correction driven by rate uncertainty and profit-taking, not a collapse of AI demand or revenue.
This is worth naming directly because it's the most concrete data point available. The selloff hit hardest in semiconductors and the biggest AI capex spenders, exactly where you'd expect if investors were pricing in more risk around the AI buildout specifically. But the coverage at the time was consistent: this looked like a repricing of stretched valuations after nine straight weeks of gains, not evidence AI usage or revenue was actually falling. Fundamental demand, by most accounts, stayed intact. Whether that holds is genuinely unknown. A correction is not proof a bubble popped, and it's not proof one didn't. We're giving it to you straight instead of pretending we know what happens next.
Should You Buy AI Stocks or an AI ETF?
We are not going to tell you. We are an AI implementation studio, not a financial advisor, and this article is not financial advice. If you're researching AI ETFs, know that most of them concentrate heavily in the same handful of names discussed above, so buying an "AI ETF" often means buying the same concentration risk under a different label.
We're flagging this because "best artificial intelligence ETF" is one of the most searched phrases connected to this topic, and we'd rather explain why we won't answer it than pretend we can. Recommending specific stocks or funds requires knowing your personal financial situation, risk tolerance, and time horizon, none of which we have. What we can tell you, because it's a fact about fund construction rather than a prediction, is that many funds marketed as "AI ETFs" hold a heavily overlapping set of the same large-cap names covered in the concentration numbers above. Diversification inside a fund with that name is not automatic. That's a question for a licensed financial advisor, not us.
What Does This Mean If You Run a Small Business, Not a Portfolio?
Whatever happens to Nvidia's stock price, the demand we see for AI implementation at the small business level is real, specific, and immediate. A restaurant that automates its phone reservations doesn't care about hyperscaler capex ratios. The task-level economics of AI adoption and the stock market's pricing of AI companies are two different questions with two different answers.
This is where our own experience matters more than any market forecast. We build AI systems, chatbots, and automation for small and mid-size businesses, and the work we get hired for has nothing to do with whether Nvidia beats earnings next quarter. A local business that saves 15 hours a week automating scheduling, or a service company that stops losing leads because its intake now runs on AI instead of a missed voicemail, gets that value whether the Magnificent Seven are up or down 20% that month. The macro debate over AI stock valuations and the micro reality of whether one automation saves one business real money are almost entirely disconnected.
If the stock market side of this is a bubble and it pops, the most likely outcome based on the dot-com precedent isn't that AI stops working. It's that a lot of overfunded, undifferentiated AI startups disappear, capital gets more disciplined, and the tools that already deliver real task-level value keep getting used and keep getting cheaper, the same way the internet kept working through 2001 and 2002 while the froth cleared out.
So, Is AI a Bubble?
Yes and no, honestly. The technology and enterprise adoption are real and growing. The valuations on a handful of AI-exposed stocks, the circular financing, and the concentration of market gains show classic bubble behavior. Both are true at once, the same way they were true of the internet in 2000. This article is not financial advice, and we are not investment advisors.
We said it plainly above and we'll say it again here: nothing in this article is financial advice, and Actual Intelligence Labs is not a registered investment advisor. We don't know if AI stocks go up or down from here, and anyone who tells you they do with certainty is selling you something. What we do know, from building this technology for real businesses every week, is that the underlying capability is not hype. What happens to the stocks pricing it is a separate question, for a financial professional, not a blog post.
