Global stock markets changed quickly on Tuesday, June 24, 2026. Many investors sold their technology stocks. They are worried about companies that work with Artificial Intelligence (AI). People are not sure if the high costs for AI are worth the money.
In the United States, the Nasdaq index fell by 2.2%. The S&P 500 index also went down by 1.43%. This happened because a few big tech companies hold a lot of value in the market. When these companies lose value, the whole market feels the effect.
The problems moved to Asia very fast. In South Korea, the stock market fell by 10%. Large chip companies like Samsung and SK Hynix lost more than 12% of their value. These companies make the memory chips that AI needs to work. Because of this, South Korea's economy is closely linked to US tech companies.
In Japan, the Nikkei 225 index also fell by 3.5%. Many investors fear that there is a "bubble" in the tech market. A bubble happens when prices go up too high and then fall suddenly. For example, the value of SpaceX dropped by 16% on Monday.
Experts say that companies are spending a lot of money on AI. Some reports say they will borrow more than $500 billion this year. Investors are now asking if these companies will make enough profit. They want to see if the AI boom will continue or if the market will fall more.
