Sarath Ratanavadi, Thailand’s wealthiest individual, is channeling up to 140 billion baht, roughly $4.3 billion, into data center expansion over the next five years. The investment, announced during a June 4 investor call, would increase Gulf Development Pcl’s data center capacity by as much as 2,000 MW.
The company currently manages approximately 200 MW through its existing collaborations. Gulf is essentially planning to 10x its capacity in half a decade.
What Gulf Development is actually building
Gulf Development has been quietly consolidating its power and telecommunications assets since 2024, positioning itself as a vertically integrated infrastructure provider.
Gulf has established a joint venture called GSA, bringing together Gulf, Singtel, and AIS to develop hyperscale data center sites. Gulf Development has also inked deals with Microsoft for data center services and AI solutions, agreements that were put in place during 2025 and 2026. In January 2026, the company formalized a collaboration with Google Cloud to develop an AI infrastructure framework.
