Thailand's foreign and domestic investment applications surged 37% year-on-year to hit $43.6 billion across 1,299 projects in the first half of 2026, driven by a massive wave of capital flowing into digital infrastructure and artificial intelligence data centers, according to the Thailand Board of Investment (BOI). The surge comes even as the global economy faces headwinds such as geopolitical tensions, energy price volatility, and supply chain restructuring, with Thailand emerging as a preferred base for investment across Southeast Asia.
Leading the capital influx is the digital sector, which reached a commanding $33 billion in investment applications. “Thailand's investment growth held steady even as the world economy faced real turbulence,” said Narit Therdsteerasukdi, Secretary General of the BOI. “This reflects strong investor confidence in Thailand's potential as a base for the industries of the future.”
This digital windfall was accompanied by robust capital commitments across other high-value industries. The electrical appliances and electronics sector drew $3.56 billion across 179 projects, while agriculture and food processing secured $1.82 billion across 131 projects. Logistics and high-value services attracted $1.19 billion across 170 projects, and the automotive sector drew $759.2 million across 122 projects. Other notable sectors included mining, metals and materials at $603.5 million, chemicals and petrochemicals at $489.1 million, and machinery, automation and robotics at $387.4 million, signaling broad-based industrial modernization.
Foreign Direct Investment (FDI) applications drove the bulk of the growth, skyrocketing 80% year-on-year to $40.5 billion across 877 projects. Singapore emerged as the top source of FDI, filing applications worth $33.2 billion across 158 projects, followed by the United Kingdom at $1.40 billion, China at $1.35 billion across 321 projects, Taiwan at $1.12 billion, and Japan at $970.1 million across 123 projects. These investments remain heavily concentrated in digital technology—including data centers, data hosting, and cloud services—followed by electronics, humanoid robotics parts, automotive parts, food and beverage, and advanced materials.
Geographically, Thailand's industrialized Central region claimed the largest share of capital at $26.7 billion across 513 projects, followed by the Eastern region at $14.7 billion. The North stood out with investment value up 93% year-on-year, led by energy and utilities, agriculture and food processing, and medical projects. To support the massive power requirements of next-generation data centers, Thailand is seeing a parallel surge in renewable energy infrastructure. The energy and utilities sector recorded 221 projects worth $1.17 billion during the first half of the year, dominated by 198 clean energy initiatives—including solar, wind, biomass, and biogas power plants—valued at $779.7 million.
Concurrently, manufacturers are investing in automation under the BOI's “Smart and Sustainable Industry” initiative, submitting 132 applications valued at $507.6 million to upgrade machinery, adopt digital technology, and integrate automation and robotics into production. The projects approved in the first half of 2026 will generate over 82,000 jobs for Thai workers and consume approximately $11.4 billion in domestic raw materials annually, boosting the nation's export capacity by more than $36.8 billion per year. “Investment value is not the only goal,” said Mr. Narit. “Real success means quality jobs, higher skills, and better income for Thai workers. It means real opportunities for Thai businesses inside the supply chain, and growth that reaches every region. That is why we will keep pushing for actual investment to happen as quickly as possible through the Thailand FastPass mechanism.” More information is available at the BOI's website: https://www.boi.go.th/en/index/.
