Your call. Will it be built?

Build odds is ArusGrid's reading of the public record, not a forecast, a rating or advice. It counts the gates this project has passed in public sources. Private progress does not show, a passed gate can be undone, and projects that pass every gate still stop. The method has not yet been tested against outcomes. How it works.

How Thailand approves, powers and taxes data centers is on Data center rules in Thailand.

Thailand, 2026-09-24. Thailand asked developers on 4 September 2026 to pause 49 data centres under construction and froze 117 pending approvals while it writes new rules, due by mid October. The government has said it cannot legally enforce the pause. No list of affected projects has been published, so no Thai project has changed stage on this basis. A separate data centre electricity tariff has been created with no rate set.

How well evidenced is it

Construction or financing is evidenced, or several independent signals agree. On record: named funder, disclosed client (confirmed), committed or approved capital, three or more sources, dated source in the last 24 months. Criteria.

AI workloads

StatusLikely

300MW modern greenfield (largest single approved IT load in Thailand); sponsor runs 360MW of Chinese hyperscale capacity and is Apollo-backed. No cooling/density disclosure.

Access to AI chips

GradeNo US licence required

This country carries no US destination-based licence requirement for advanced AI chips as the rules are enforced today. Access is a commercial matter between the project and its vendors. Criteria.
