AI stocks rally, Burry sounds bubble alarm

AI stocks ripped higher again this week, and the move was broad enough that it stopped looking like just another Nvidia story. AMD’s forecast lit the fuse, chip stocks followed, and the Nasdaq and S&P 500 both hit fresh records. Then Michael Burry stepped in with the mood-killer — saying the market now feels like the last months of the 1999-2000 bubble. That contrast is the whole story: the rally is real, but so is the fear that prices are outrunning what the businesses can actually deliver. ### What actually kicked this off? Advanced Micro Devices gave investors the clean trigger. On May 6, AMD forecast quarterly revenue above expectations on strong demand for data-center chips, and the stock jumped almost 19% to an all-time high. That spilled into the rest of the AI complex — Intel rose 4.5% that day, Nvidia gained 5.7%, and the broader chip index rallied 4.5% as traders piled back into anything tied to AI infrastructure.

Reuters’ market wrap showed the S&P 500 and Nasdaq both closing at record highs on the same session that AMD exploded upward, with information technology among the strongest sectors. Investors also had a friendlier macro backdrop — lower oil and less fear around Middle East escalation — but the AI earnings story was the part that gave the rally its speed.

One of the more notable shifts this week was that money started rotating across the chip stack instead of crowding only into the obvious winner. Intel surged on a reported Apple chip deal, AMD had the earnings catalyst, and the industry group was up 4.6% in Friday trading even as some AI-linked names like CoreWeave sold off after a weak forecast. (money.usnews.com) Basically, investors are still buying the AI buildout, but they are getting pickier about where they want the exposure. ### So why is Burry calling bubble? His argument is less “AI is fake” and more “price action has stopped caring about normal inputs.” In his May 8 Substack post, picked up by CNBC, Burry said stocks were no longer moving in a logical way off jobs data or consumer sentiment. He pointed instead to the Philadelphia Semiconductor Index and said the setup felt like the final stretch before the dot-com bust. (finance.yahoo.com) The number that makes people listen is this one: the SOX was up more than 10% for the week and 65% in 2026. That is the kind of move that starts to look self-feeding. ### Is he saying a crash is next week? No — and that is the catch with bubble calls. Even the bears are not necessarily saying the trade ends tomorrow. In the same CNBC piece, Paul Tudor Jones also said the environment feels similar to 1999, but he floated the idea that the bull market could keep running for another year or two before any real break. That is why traders can sound euphoric and nervous at the same time. (cnbc.com) Momentum can keep going long after valuation starts looking silly. ### What should readers watch now? Watch whether the rally keeps broadening and whether earnings keep justifying it. If more companies can do what AMD did — show real demand and raise guidance — the market has something solid underneath the hype. If the gains keep coming mostly from multiple expansion and “AI” headlines, Burry’s warning gets harder to dismiss. The bottom line is simple: this week’s rally was powered by real numbers, but the speed of the move is what makes people whisper “bubble.” (money.usnews.com) (cnbc.com)
