Wall Street ended October with a rough session. On Friday, October 30, a sharp selloff in technology stocks pulled the broader market down and revived a big question: will the enormous spending on artificial intelligence deliver the profits investors are hoping for?
What Happened
The selloff was sparked by disappointing quarterly results from Intel and Amazon that were released late Thursday. Intel shares plunged 28.6%, the company’s worst drop since 1974. The S&P 500 fell 1.8% and the Nasdaq Composite 2.8%, while the Philadelphia Semiconductor Index lost 7.2%. According to NBC News, US tech stocks wiped out more than $1 trillion in market value. It was Wall Street’s worst day since June.

The Bigger Worry: Is AI Spending Too High?
The Associated Press reported that the selloff reflects worries that Wall Street’s excitement around AI pushed prices too high. Reuters noted that major AI spending by large tech firms, partly funded by outside financing, made investors nervous. This connects directly to recent headlines about record borrowing to buy AI chips.

Why You Should Care Even If You Don’t Pick Stocks
Many Americans own big tech companies without realizing it. Index funds and target-date funds in 401(k) accounts hold large amounts of the same companies that fell. So when tech drops sharply, retirement balances can dip too, even if the owner never bought a single share directly.
There is also a link to prices. Intel’s warning put a spotlight on the wider consumer-device supply chain, from computers to game consoles, which is already dealing with higher memory prices.

Is This a Crash?
Not necessarily. A one-day drop of this size is notable, but markets move up and down, and one session does not tell us where things go next. Analysts disagree: some see a healthy reset after a long rally, while others see the start of tougher scrutiny of AI profits.
