Asian markets charged higher Tuesday as the artificial intelligence rally showed no signs of losing momentum. The Nikkei 225 rose 1.2%, while the Shanghai Composite gained 0.8% and South Korea's KOSPI climbed 1.5%. Tech-heavy indices led gains across the region, with semiconductor and AI chip designers posting particularly strong performances.
Taiwan Semiconductor Manufacturing Company (TSMC) surged on renewed demand expectations from data center expansions. South Korean chipmakers Samsung Electronics and SK Hynix both extended their upward runs, benefiting from a global race among cloud providers to build AI infrastructure. Japanese technology stocks, from robotics to industrial AI applications, outperformed broader market gains.

Data center operators, semiconductor manufacturers, and AI software firms all captured buyer interest.

Sentiment shifted after a period of caution in late 2024. Fresh earnings expectations and strategic partnerships around AI infrastructure spending reignited bullish positioning across Asia's tech sector. American chip stocks had set the tone overnight, with Nvidia's latest guidance supporting broader semiconductor strength globally.
Analysts noted that Asian manufacturers hold structural advantages in AI infrastructure buildout. Taiwan's foundry dominance, South Korea's memory chip leadership, and Japan's supplier ecosystem position the region to capture disproportionate gains from the multi-trillion-dollar AI investment wave.
Broader market strength reflected risk-on sentiment. Emerging market currencies stabilized after earlier volatility tied to U.S. Federal Reserve policy expectations. Bond yields climbed modestly as investors shifted capital from fixed income into equities.
THE TAKEAWAY: Asia's AI chipmakers are capturing outsized returns from acceler
