Nikkei Falls 0.81% on AI Slowdown Fears

Japan's benchmark index closed at a six-week low as leaders urged a pause in AI development, triggering a sharp sell-off in tech stocks.
The Nikkei 225 index dropped 518.35 points on Monday. This represented a 0.81 percent decline from the previous session. The index closed at 63,492.99. This level marks the lowest finish since July 30.
The sell-off followed public calls from U.S. AI leaders to reduce development speed. Dario Amodei, CEO of Anthropic, published an essay urging a slower pace for safety reasons. Elon Musk and Sam Altman supported this view. These statements triggered immediate selling in technology sectors.
Tech Stocks Lead the Decline
The Nikkei index briefly lost two percent during the morning session. Investors offloaded shares in AI and semiconductor companies. Kioxia shares fell 6.4 percent in the final tally. SoftBank recorded the largest drop among major constituents.
SoftBank declined by 10.7 percent. This company is heavily exposed to the AI investment cycle. Many Nikkei heavyweights depend on AI suppliers or investors. A slowdown in this sector threatens their earnings directly.
Broad Market Indices Diverge
The broader TOPIX index moved in the opposite direction. It gained 29.91 points on the day. This represented a 0.74 percent increase. The index ended the session at 4,058.21.
This divergence highlights sector-specific volatility. Oil prices also spiked above 107 U.S. dollars per barrel. The Nikkei 225 remained the primary indicator of risk appetite in Tokyo. The gap between the two major indices widened significantly.
Central Bank Decision Expected
The Bank of Japan meets this Friday. Markets expect a quarter-point interest rate hike. Analysts suggest this move is already priced in. Investors appear focused on the AI narrative rather than monetary policy.
Timothy Pope, an analyst, noted that Tokyo felt the pain of the AI slowdown. The source GN auto markets/indices reported on this stock index movement. The combination of tech weakness and oil strength defined the trading day. The Nikkei closed well below its recent highs.
