Stock Market Today: Chip Stocks Plunge on AI Funding Worries

The stock market today is firmly in the red as a global rout in chip stocks deepens. Nvidia, AMD and Dell are leading the declines, with selling spreading from the United States across Asia as investors question whether the money behind the artificial-intelligence buildout will keep flowing.

It is the kind of session that reminds investors how concentrated this market has become. Semiconductors sit at the center of the AI trade, so when confidence in AI funding wobbles, the damage shows up fast — and everywhere at once.

Stock Market Today: What Triggered the Chip Sell-Off

According to CNBC, the spark for the stock market today sell-off is worry about AI funding. Investors are asking whether the enormous capital expenditure earmarked for AI data centers can be sustained — and what happens to chip demand if it cannot. Nvidia, AMD and Dell sold off as those fears rippled through global tech.

The weakness did not stop at the US close. In Asia, the stock market today rout pulled in heavyweights including SK Hynix, Samsung and SoftBank, turning a US-led slide into a genuinely global tech retreat.

The speed of the move is what has caught attention. Chip stocks had been the market’s leadership group for much of the AI cycle, which means crowded positioning is now working in reverse: funds that piled into the same names are heading for the exit at the same time.

How Big Is the Stock Market Today Rout?

A $2 trillion wipeout in US chip stocks

CNA reports that US chip stocks are set to wipe out roughly $2 trillion in market value after the latest wave of selling. A figure that large puts the stock market today episode among the sharpest sector drawdowns of the AI era — not a single bad session for one company, but a wholesale repricing of the group.

For context, $2 trillion is more than the market value of most entire national stock markets. When a single sector sheds that much that quickly, the effects spill over: index futures sag, related hardware and memory names get dragged along, and volatility spreads into the broader market.

Billions pour into leveraged ETF bets

Not everyone is running for cover. Bloomberg reports that a roughly $1 trillion chip rout is drawing billions of dollars into leveraged ETF bets, as some traders position for a snapback in the stock market today. It is a high-risk way to play a bounce: leveraged products amplify gains, but they also amplify losses if the slide continues.

That split — long-term holders de-risking while tactical traders bet on a rebound — is typical of the later stages of a sharp sell-off, and it usually means elevated volatility until one side is proven right.

What to Watch Next in the Stock Market Today

For the stock market today, the next catalysts are straightforward. First, commentary from chipmakers and their biggest customers on AI capital spending — any sign that data-center budgets are being trimmed would extend the slide. Second, upcoming earnings from the semiconductor complex, where guidance matters more than the reported quarter. Third, the price action itself: whether dip-buyers defend recent support levels or the selling broadens into other sectors.

Traders tracking the fallout can screen for chip stocks seeing the heaviest pressure on Meyka’s US screener, and watch unusual volume for signs of capitulation or institutional buying. Meyka, the AI-powered stock and crypto research platform, also lets investors compare valuations across the semiconductor group before deciding whether the dip is an opportunity or a warning.

The bigger question for the stock market today is whether this is a healthy reset or the start of something deeper. AI-related capital spending is still enormous by any historical standard, and demand for advanced chips has not collapsed overnight. But markets price the future, not the present — and right now, the future of AI funding looks less certain than it did a week ago.
