Japan's Nikkei rises as Anthropic IPO filing lifts AI-shares

Japan’s Nikkei climbed 1.91% to 63,374.45 on Tuesday, after advancing as much as 2.4% during the session, Business Recorder reported. The broader Topix gained 0.61% to 3,997.09. Anthropic’s filing for a US initial public offering and an overnight rise in the Philadelphia semiconductor index supported Japanese shares tied to artificial intelligence.

Advantest, which makes chip-testing equipment, jumped 10%, while SoftBank Group added 6.94% and Tokyo Electron rose 3.35%. The Philadelphia chip index increased 2.8%, and the Nikkei was positioned to end a three-session decline if gains held. However, the market advance was narrow: 49% of Tokyo Stock Exchange prime-market shares rose, 47% fell and 2% were unchanged. Investors were cautious ahead of results from US technology giants Alphabet and Microsoft, while Daiichi Sankyo dropped 6.53%, the Nikkei’s largest percentage decline.
