Nonetheless, Fast Retailing managed to post slight gains, offering a degree of stability to the overall Nikkei performance amidst a gloomy market outlook.

Gartner204.22(-13.19%)Sysco74.11(-9.33%)Zebra Technologies329.50(-8.76%)Coterra Energy32.56(-8.62%)Investors worried that a stronger-than-expected Democratic showing could lead to stricter oversight of AI infrastructure, with broader implications for sectors including technology, healthcare, banking and cryptocurrencies.
"Democrats are winning seats in some key states. That fuelled caution for stricter regulations on AI infrastructure investment," said Takamasa Ikeda, a senior portfolio manager at GCI Asset Management.
Democrats flipped a Republican-held Senate seat in North Carolina and performed strongly in several Republican-leaning House districts in Florida, raising hopes they could regain control of Congress.

In Japan, shares of chip-testing equipment maker Advantest and Tokyo Electron fell 7.8% and 6.28%, respectively, while technology investor SoftBank Group slipped roughly 9%. Memory chip maker Kioxia was down 11.55%.
Makers of fibre-optic cables, key materials for data centres, also fell, with Fujikura and Furukawa Electric down 8.49% and 9.66%, respectively.
A stronger-than-expected Democratic advance is a headwind for Japanese tech shares, but strong earnings and outlooks from companies such as Advantest and Tokyo Electron should help underpin valuations, said Kazuaki Shimada, chief strategist at IwaiCosmo Securities.
Uniqlo-brand owner Fast Retailing rose 1.21% and provided the biggest support to the Nikkei.
