05:41 AM EST, 02/03/2026 (MT Newswires) -- Asian stock markets rallied Tuesday, with Japan's Nikkei 225 scaling new peaks and Seoul's broad KOSPI index rising 6.8% to a new record high, as traders roared back into AI- and tech-issues after overnight gains in peer issues on Wall Street.

US-based Palantir Technologies (PLTR) late Monday reported a large Q4 revenue surge due to accelerating AI-connected demand. The software-builder also issued an upbeat guidance.

With tech in front, Hong Kong, Shanghai and Tokyo finished in the green, as did most other regional exchanges.

In Japan, the Nikkei 225 opened higher and rose to the close, finishing up 3.9% on tech-strength and also on the outlook for expansionist fiscal policies from the ruling Liberal Democratic Party, following possible election victories on Sunday.

The benchmark Nikkei 225 rose 2,065.48 to 54,720.66, a fresh all-time apex, as gaining issues outnumbered losers 207 to 16.

Leading the upside was Sumitomo Electric Industries, up nearly 13%, while Yamaha Motor declined 10%, with both moves following earnings reports.

In Hong Kong, the Hang Seng Index opened higher, wobbled, but held ground, closing up 0.2%, although tech issues lagged on possible tax changes underway in China.

The broad gauge Hang Seng rose 59.20 to 26,834.77, as gaining issues outnumbered losers 61 to 27. The Hang Seng TECH Index lost 1.1% on the day, while the Mainland Properties Index rose 1.6%.

Tech shares lost ground after Beijing authorities indicated they may target financial and internet value-added services for tax-rate adjustments, The South China Morning Post reported.

Leading the upside was CSPC Pharmaceutical, gaining 8.1%, while video-sharing platform Kuaishou Technology declined 4.6%.

On the mainland, the Shanghai Composite rose 1.3% to 4,067.74.
