Stock markets in Japan and South Korea opened to a new high on May 11, 2026, extending a strong rally driven by the reduction of tensions between countries and the need for AI-related technology.
The Nikkei 225 gained nearly 1% on the open, while South Korea’s KOSPI jumped nearly 4%, marking one of the strongest starts for Asian markets this year. According to market data, Japan’s Nikkei 225 rose 0.78% to 63,201.36, surpassing its historic high of 62,833 set a few days earlier.
Meanwhile, South Korea’s KOSPI rose 3.85% to 7,786.73, breaking above the 7,700 level for the first time and gaining in Asian markets.
Major semiconductor and tech stocks also posted big gains. Samsung Electronics jumped more than 5%, while SK hynix rose more than 8%, both companies rose sharply.
AI Boom Boosts Asian Markets
The main driver behind the conference continues to be global intelligence.
South Korea recently reported a massive 139% year-on-year increase in semiconductor exports in the first quarter of 2026, fueled largely by rising demand for memory chips that support AI data centers around the world.
The increase has bolstered business confidence in Asian semiconductor giants, especially as global companies continue to ramp up investment in AI.
The conference also highlights how Asian markets are increasingly becoming players in the global AI arena, particularly in semiconductors, chip manufacturing, and advanced hardware.
Geopolitical Optimism Boosts Investor Sentiment
Markets also did well in the management of international events involving the United States and Iran.
President Donald Trump recently described talks with Iran as “very productive,” raising hopes for a deal that could ease tensions and improve global market stability.
At the same time, investors are shifting more money to Asian stocks as a growth opportunity and a safe haven at a time of global uncertainty.
South Korea’s stock market has now overtaken Britain and Canada as the world’s seventh largest stock market, reflecting the global rise of Asian technology and semiconductor companies.
