Thailand's foreign and domestic investment applications rose 37% year-on-year to reach $43.6 billion (approximately 1.47 trillion baht) across 1,299 projects in the first half of 2026, according to the Thailand Board of Investment (BOI). The surge was propelled by a massive wave of capital flowing into digital infrastructure and artificial intelligence (AI) data centers, even as global economic headwinds persist.
The digital sector led the influx, accounting for a commanding $33 billion (approximately 1.12 trillion baht) in investment applications. This digital windfall was accompanied by robust commitments across other high-value industries. 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) across 170 projects, and the automotive sector drew $759.2 million (approximately 25.7 billion baht) across 122 projects.
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) across 11 projects, with China close behind at $1.35 billion (approximately 45.8 billion baht) across 321 projects. Taiwan and Japan also contributed significantly, with investments of $1.12 billion and $970.1 million, respectively.
These investments remain heavily concentrated in digital technology—including data centers, data hosting, and cloud services—followed by electronics and electrical appliances such as optical transceivers, printed circuit boards, hard disk drives, and data-center networking and cooling systems. Humanoid robotics parts, automotive parts, food and beverage, and advanced materials also saw notable activity.
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 (approximately 39.5 billion baht) 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 (approximately 26.4 billion baht).
Manufacturers are also investing in automation to remain competitive. Under the BOI's 'Smart and Sustainable Industry' initiative, companies submitted 132 applications valued at $507.6 million (approximately 17.2 billion baht) to upgrade machinery, adopt digital technology, and integrate automation and robotics into production and services.
'Thailand's investment growth held steady even as the world economy faced real turbulence,' said Mr. 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.' The projects approved in the first half of 2026 are expected to generate over 82,000 jobs for Thai workers and consume approximately $11.4 billion (approximately 386 billion baht) in domestic raw materials annually. They are also expected to boost the nation's export capacity by more than $36.8 billion (approximately 1.24 trillion baht) per year.
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.
The BOI approved investment promotion applications for 1,300 projects valued at $38.7 billion (approximately 1.31 trillion baht) in the first half of 2026. 'Investment value is not the only goal,' Mr. Narit said. '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.'
