Global AI Selloff Sends Asian Markets Down 6%

The selloff in technology stocks that began in U.S. semiconductor shares earlier this week accelerated into a global rout on Friday. Benchmark indexes in Japan and Taiwan fell as much as 6%, Reuters reported, with one analyst reaction roundup carrying the word "bloodbath" in its description of the session across Asian markets.

The declines were an extension, not a new event. U.S. chip stocks have been sliding all week, and the U.S. semiconductor index is on track for its worst weekly performance since last year's so-called liberation day selloff, according to the Financial Times. U.S. stocks were headed for weekly losses as well, with semiconductor names continuing to pull major indexes lower. The Nasdaq has absorbed the largest share of the damage, and Yahoo Finance reported that stocks also fell after Netflix's results missed expectations.

At the center of the reversal is investor skepticism about artificial intelligence spending. The FT reported that investors are questioning the scale of outlays on AI, the same spending that has powered much of the market's gains. Because AI and semiconductor companies carry heavy weightings in major indexes, the pullback is not confined to technology portfolios. It is flowing through index funds and retirement accounts held by ordinary investors.

The context

AI-related spending has been a primary driver of stock market gains, and companies tied to that buildout, including chipmakers, grew into some of the largest weightings in major U.S. indexes. That concentration worked in investors' favor on the way up and is working against them now: when the largest index components fall together, broad benchmarks fall with them.

The current rout started in U.S. semiconductor shares earlier in the week before spreading to Asian markets by Friday. The comparison point for the damage is last year's liberation day selloff, which the Financial Times cited as the last time the U.S. semiconductor index had a worse week. Named companies in the selloff include Nvidia and Micron, along with chip-heavy markets in Taiwan and South Korea, where semiconductor firms dominate local benchmarks.

Why it matters

Because AI and chip stocks make up an outsized share of major indexes, this is not a story confined to technology investors. Index funds and 401(k)-style retirement accounts that track broad benchmarks are exposed to the same names driving the declines, so the losses reach households that never bought a single chip stock. The episode also tests the premise behind much of the past year's rally: that massive AI spending will pay off. If investors continue to doubt that, the stocks that led markets higher have the most room to fall.

What’s next

The immediate question is whether the selling carries into next week's U.S. trading or stabilizes after Friday's declines in Asia. Watch whether skepticism about AI spending persists, since that doubt is what the Financial Times identified as the driver of the reversal. Also worth tracking: whether the U.S. semiconductor index finishes the week with its worst loss since last year's rout, and how heavily weighted names like Nvidia and Micron trade from here.
