What happened

Japan's Nikkei 225 (^N225) fell 2.65% to 62,907.84 on Thursday as chip stocks sank on worries that AI spending may slow in 2027. Early on, chip stocks were giving back Wednesday's gains: Tokyo Electron was down 4%, Screen Holdings 6% and SoftBank Group 3%. By the close, Tokyo Electron had lost about 6.5% and SoftBank about 6.9%. Investors are asking whether companies will keep spending heavily on AI computing next year.

Why it matters

The Nikkei 225's drop matters because chip-equipment makers such as Tokyo Electron carry a big weight in it, so their slide drags the whole index down. These companies sell the machines used to make AI chips, so doubts about AI spending hit their sales outlook first. Rising oil prices after reports of damaged tankers near the Strait of Hormuz added to the nervousness.
