Nikkei Slips Below 63,000 as AI Leaders Signal Development Pause

Tokyo’s Nikkei average fell below 63,000 on Monday after AI executives urged a slowdown in development, triggering a sharp sell-off in semiconductor and infrastructure stocks.
The Nikkei Stock Average dropped 1,031.82 points to 62,979.52 on September 14, briefly breaching the 63,000 threshold for the first time since August 4. The decline followed remarks by top AI executives who suggested a need to slow development, prompting immediate selling in technology-heavy sectors.
Investors reacted to signals that capital expenditure on data centers and semiconductor equipment would grow more slowly than projected. SoftBank Group, a major investor in OpenAI, fell more than 10% at one point, while equipment makers Advantest and Tokyo Electron faced significant pressure as demand outlooks were revised downward.
Executive Remarks Trigger Sector Sell-Off
Dario Amodei of Anthropic and Sam Altman of OpenAI both indicated plans to temper the pace of AI advancement, citing risks of misuse and loss of control. These comments directly impacted market sentiment regarding future revenue streams for hardware suppliers.
A report from Fortune magazine added to the negative sentiment, stating that OpenAI would not pursue an initial public offering in 2026. This delay removed a key exit strategy for SoftBank Group, compounding the stock’s losses alongside the broader hardware sector decline.
Geopolitical and Regional Market Pressures
Escalating tensions in the Middle East further weighed on investor confidence. Saudi Arabia temporarily shut down crude oil pipelines after attacks, pushing New York crude futures to approximately $103 per barrel. Higher energy costs pose a direct margin threat to Japanese importers and industrial firms.
The sell-off extended to South Korea, where Samsung Electronics fell 3.85% and SK Hynix dropped 6.24%. Equipment suppliers such as TES and TSE also declined sharply, reflecting a regional consensus that slower AI competition will reduce memory demand and capex growth.
Forward Outlook for Tech Spending
Market participants are now closely monitoring upcoming capital spending announcements from major tech firms. With AI stocks leading global equity gains in 2026, any sustained reduction in development pace could prolong the current correction phase for the sector.
According to GN stocks/chips, the focus has shifted from growth acceleration to risk assessment. Investors are re-evaluating the sustainability of previous spending cycles, leading to a broader rotation out of high-beta semiconductor names and into more defensive holdings like Fast Retailing.
