Note on TikTok: TikTok (ByteDance) received BOI approval in May 2026 for 842 billion baht (~US$25.5B) — the largest single BOI approval in Thailand's history. This figure is excluded from the chart because TikTok does not build or operate its own data centers; the commitment represents workload deployment contracted across existing operator infrastructure (including True IDC, AWS, and others already shown). Including it would double-count supply-side capacity already captured above.
