Did Investors Get Too Far Ahead of the Artificial Intelligence (AI) Revolution? The Market Is Starting to Say Yes.

By Reuben Gregg Brewer – Mar 28, 2026 at 1:15PM ESTKey PointsArtificial Intelligence is a powerful technology.The internet was a powerful technology.Being a powerful technology didn't stop dot-com stocks from collapsing after a rapid advance.Investors have a long and storied history of finding a good idea and then collectively investing in it. The end result is lemming-like behavior that pushes stocks up to unsustainable heights. This is how bubbles arise. However, at some point, the reality of the investment idea and the price investors are paying collide, and investors start selling, triggering a rush for the exits. That's when the bubble bursts. The bubble-and-burst dynamic is so common that entire books have been written about it, with examples dating back to the Tulip Bulb Mania of the 1600s. So the fear about an artificial intelligence bubble isn't something to be ignored. If history is any guide, this technological advance will lead to investment excess. There are signs that it may have already reached that point. Artificial intelligence is important, but so was the internet Tulip bulbs may seem like a silly example of investment excess, but that didn't stop the price of tulip bulbs from skyrocketing and then crashing. More recent examples of bubbles are a bit more serious. In fact, the last big bubble involved a technology of immense importance: the Internet. Image source: Getty Images. The dot-com bubble at the turn of the century was huge. The technology-heavy Nasdaq-100 index rose sharply, then lost more than 80% of its value. The bear market took a couple of years to play out and was filled with relief rallies, with tech stocks rising sharply before continuing their declines. It was a very difficult period for investors. The internet was very real, and it did change the world. But investors got too far ahead of the internet, and many paid a steep price for their exuberance. Artificial intelligence (AI) is very real, and it will likely change the world, too. But AI stocks could be at an important inflection point just like dot-com stocks were over 25 years ago. ^NDX data by YCharts The Magnificent Seven are down again The poster child for the AI revolution is Nvidia (NVDA 2.13%). The chipmaker's stock is down around 17% from its 2025 high-water mark.

Roundhill Magnificent Seven ETF (MAGS 2.77%) is a collection of high-profile stocks led by Nvidia that drove the market higher for years. That ETF is down roughly as much as Nvidia. That's still correction territory, not a bear market, which requires a fall of 20% or more. What's interesting is that Nvidia and Roundhill Magnificent Seven ETF both fell more than 20% in early 2025. At that point, concerns about economic growth emerged. Investors are again concerned about economic growth, only this time, a major geopolitical conflict has driven energy prices sharply higher. Higher energy prices are already leading companies to raise prices, thanks to higher transportation costs.

For example, fertilizer supplies are being impacted. That will make it more costly to produce food or lead to lower crop yields if farmers skimp on these vital plant nutrients. Chemicals and other products made from oil and natural gas are also at issue. A recession seems a much more realistic threat this time around, noting that energy markets will take time to return to normal even after the conflict ends.

For example, SoundHound (SOUN 2.81%) is down around 75% from its 2025 highs. The highest risk stocks tend to break first when a bubble does, eventually, burst. Recessions, bear markets, and the long road back If there is a recession and AI stocks fall, the Nasdaq-100 chart above is a chilling warning. The dot-com crash played out over a couple of years, and it took more than a decade for the index to work its way back to break even. It may be too early to say the AI bubble has officially burst, but taking some money off the table wouldn't be the worst decision to make, either, given that the risk of a recession seems greater now than it did in early 2025.Read NextMar 26, 2026 •By Reuben Gregg BrewerTech Stocks Have Lost Over $1 Trillion in Value This Year.
