• Country snapshot (2024–2025):

Definition note: Southeast Asia totals exist in two series — e-Conomy SEA (broad definition, including non-platform and services, $181B/2025) and Momentum Works (platform GMV only, $157.6B/2025); Thailand nationwide ecommerce $200–220B is an extremely broad definition, and Malaysia RM937.5B (9M2025) is a national digital-economy statistic — none of these is directly comparable to B2C GMV.

7. Southeast Asia

Ranking basis: by Momentum Works Ecommerce in SEA 2026 platform GMV (CY2025 total $157.6B, +22.8%; top 3 hold 98.8%). Another definition, e-Conomy SEA (Google-Temasek-Bain), puts 2025 ecommerce at about $181B (including non-platform channels) — the two definitions must not be mixed. Ranks 4–5 are estimates (Momentum Works only publishes granularity for the top three; the long tail totals only ~1.2%).

⚠️ Definition and conflict notes: 1. Two total-size definitions: Momentum Works platform GMV $157.6B (2025) vs e-Conomy SEA ecommerce $181B (including non-platform) — cite the series when quoting. 2. TikTok Shop SEA $45.6B (TNGlobal "~2x") differs from some media "+132%" and Indonesia-only $13.1B (MOCA) (the latter may understate or exclude Tokopedia volume). 3. Do not mix Shopee Southeast Asia $83.2B with global $127.4B; Lazada GMV is a derived estimate (Alibaba does not disclose). 4. "Chinese platforms about 50% of SEA GMV": TikTok Shop (~29%)+Lazada (~17%) ≈46%, plus Temu/Shein (not in the platform GMV series) approaches 50% — partially supported. 5. Country divergence: Indonesia 2025 platform GMV $57.7B (Shopee 54%), growth slowing (Ministry of Trade: ecommerce only +2.2%); Vietnam Top4 platform sales 429 trillion dong (+34.8%), TikTok Shop share up to ~41%; Thailand the fastest growth (~+52%, second-hand).
