Asian markets rally on Anthropic IPO optimism, tech stocks surge

Asian shares mostly rose on Tuesday, led by technology and semiconductor stocks after Anthropic filed to list on Nasdaq, Mettis Global reported. South Korea’s Kospi advanced 3.8% and Japan’s Nikkei 225 gained 1.7%, while the Kosdaq rose 2.9% and Topix added 0.4%; Australia’s S&P/ASX 200 slipped 0.32%. Japanese chip-related shares also climbed, including an 8.8% rise for Advantest and a 7.6% gain for SoftBank Group.

The regional advance followed gains in US technology shares, with the Nasdaq Composite up 0.8% and the S&P 500 higher by 0.7% on Monday. The report said Asian technology stocks have recently been volatile, with concerns about borrowing for AI infrastructure and ongoing US-Iran tensions among the factors investors are watching. Markets are also focused on major company earnings and the Federal Reserve’s policy meeting this week, while futures pointed to further gains in Japan and Hong Kong.
