Thailand's foreign and domestic investment applications jumped 37% year-on-year to reach $43.6 billion (approximately 1.47 trillion baht) across 1,299 projects in the first half of 2026, propelled by a massive wave of capital flowing into digital infrastructure and artificial intelligence (AI) data centers, according to the Thailand Board of Investment (BOI).
The surge comes even as the global economy faces headwinds including 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 (approximately 1.12 trillion baht) 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.”
Foreign Direct Investment (FDI) applications drove the bulk of the growth, skyrocketing 80% year-on-year to $40.5 billion (approximately 1.37 trillion baht) across 877 projects. Singapore emerged as the top source of FDI, filing applications worth $33.2 billion (approximately 1.12 trillion baht) across 158 projects. The United Kingdom followed as the second-largest investor at $1.40 billion (approximately 47.2 billion baht), with China close behind at $1.35 billion (approximately 45.8 billion baht) across 321 projects, Taiwan at $1.12 billion (approximately 38.0 billion baht), and Japan at $970.1 million (approximately 32.8 billion baht).
Beyond digital, other high-value sectors also attracted robust capital. The electrical appliances and electronics sector drew $3.56 billion (approximately 120.2 billion baht) across 179 projects, while agriculture and food processing secured $1.82 billion (approximately 61.4 billion baht) across 131 projects. Logistics and high-value services attracted $1.19 billion (approximately 40.2 billion baht), and the automotive sector drew $759.2 million (approximately 25.7 billion baht). Additional 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.
These investments remain heavily concentrated in digital technology including data centers, data hosting, and cloud services, followed by electronics such as optical transceivers, printed circuit boards, hard disk drives, and data-center networking and cooling systems, along with humanoid robotics parts, automotive parts, food and beverage, and advanced materials. Geographically, Thailand’s industrialized Central region claimed the largest share at $26.7 billion, followed by the Eastern region at $14.7 billion.
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, dominated by 198 clean energy initiatives including solar, wind, biomass, and biogas power plants valued at $779.7 million. Concurrently, under the BOI’s “Smart and Sustainable Industry” initiative, companies submitted 132 applications valued at $507.6 million to upgrade machinery, adopt digital technology, and integrate automation and robotics.
The projects approved by the BOI 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, accounting for 42% of total raw material use, and are expected to boost the nation’s export capacity by more than $36.8 billion per year. The BOI approved investment promotion applications for 1,300 projects valued at $38.7 billion in the period.
“Investment value is not the only goal,” Mr. Narit stated. “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, not just a few.” The BOI will continue to push for rapid actualization of investments through its Thailand FastPass mechanism.
