TOKYO: Japan’s Nikkei share average rose on Tuesday as trading resumed after a long holiday weekend, with AI-related stocks rallying on expectation of further investment in AI infrastructure after a report of a possible Nvidia-OpenAI deal.
The Nikkei rose 0.91 percent by 0343 GMT, while the Topix edged up 0.19 percent.
“Although it is still a speculation, investors reacted to the news about Nvidia and OpenAI. Expectations for growth in AI infrastructure grew,” said Naoki Fujiwara, a senior fund manager at Shinkin Asset Management.
Nvidia is close to finalising a USD30 billion investment in OpenAI as the chipmaker moves to take a stake in one of its largest customers, Reuters reported last week.
Fibre-optic cable makers jumped, with Furukawa Electric surging 16 percent.
China added Japanese companies to a list of export controls aimed at curbing what it termed Japan’s “remiliterisation.”
