Thai stock market thriving as surprise beneficiary of AI boom

People visit the Delta Electronics booth during the annual Computex trade show in Taipei, Taiwan, on June 3, 2026. Thailand's stock market is having the best year among Southeast Asian peers, as investors discover an unlikely source of exposure to the global artificial-intelligence boom. Much of that gain has come from Delta Electronics (Thailand). The maker of power systems for AI data centers has surged more than 80% this year and became Thailand's first $100 billion company, large enough to be worth more than the next four largest Thai stocks combined. While the country lacks the semiconductor champions of Taiwan or South Korea, investors are increasingly recognizing its role in supplying the infrastructure behind AI. "Thailand isn't a pure AI market, but its exposure to data centers, electronics, power systems and digital infrastructure gives investors a new way to view Thai equities beyond the traditional tourism, banks and domestic consumption cycle," Bloomberg Intelligence Strategist Sufianti said in a note. Delta's rise is the clearest evidence of that shift.
