Nasdaq Plunge 2% as AI Bubble Concerns Rises (Oct 2025)

Global markets are starting to show signs of trouble. On Tuesday, major U.S. indexes like the S&P 500 and Nasdaq dropped more than 1%. This wasn’t caused by one big event, it’s mostly because investors are getting nervous about how expensive tech stocks have become and whether the AI boom can keep going strong.

Big Banks Are Worried

Top leaders at Goldman Sachs and Morgan Stanley say the stock market could fall by 10% to 20% in the next year or two. They’re concerned that tech stocks are too expensive and that AI investments are growing too fast without clear long-term profits.

Palantir, a popular AI company, reported great earnings for the third quarter. But even with strong results, its stock dropped 7%. This shows that investors are starting to worry, even when companies are doing well.

Tech Stocks Are Falling

Palantir isn’t the only one. AMD, another tech company that’s had a big year, saw its stock fall 4% after reporting earnings. Super Micro Computer dropped 9% after missing profit and revenue expectations. Even Bitcoin fell to $100,000 for the first time since June.

This shows that even small disappointments can cause big drops when investors are already feeling unsure. Some analysts anticipate that the market might be ready for a bigger reset.

The Drop Is Spreading Worldwide

The tech selloff didn’t stay in the U.S. Stock markets in Japan and South Korea fell more than 2%, and European markets were down about 0.5%. U.S. stock futures didn’t bounce back overnight either.

The U.S. dollar is getting stronger, and South Korea’s currency hit its lowest point in seven months. 

Final Words

The stock market has been rising thanks to excitement around AI and strong company earnings. But now, even small setbacks are causing big reactions. With major banks warning of a possible drop and tech stocks starting to slide, investors are preparing for a bumpy ride. Whether this is just a short pause or the start of a bigger downturn is still unclear, but the warning signs are hard to ignore.
