4. China

Ranking basis: by GMV (third-party estimates, calendar year) — Chinese platforms almost never disclose GMV: only Kuaishou discloses officially; JD.com stopped after 2017, Alibaba discloses growth rates only, and Pinduoduo/Douyin never disclose. So 4 of 5 GMVs are third-party estimates (±10–30% error) and must be labeled.

⚠️ Key definition notes: 1. Ranks 2–4 are contested: 2024 estimates put JD.com (~¥4.5 trillion) ≥ Pinduoduo (~¥4.3–4.4 trillion) > Douyin (¥3.5 trillion); 2025 estimates have Douyin (~¥4.3 trillion) catching/overtaking JD.com, and 100EC says Douyin has already overtaken Pinduoduo and JD.com (JD.com denies this). This table presents them as a tie. 2. GMVs are all third-party estimates (except Kuaishou); revenues are official disclosures but use different definitions (marketplaces recognize only commissions/ad revenue; JD.com 1P recognizes full merchandise value). 3. Data definitions: Alibaba is fiscal year (April–following March); the others are calendar year; NBS online retail ¥15.97 trillion (2025, +8.6%) includes services and is not directly comparable with platform GMV. 4. Kuaishou GMV conflict: media report ~¥1.6 trillion vs 100EC report ¥521.8 billion (possibly a quarterly figure or a transcription error).

2025 developments: the price war ebbed (618 "abandon the price war"); Douyin "squeezed water" and shifted toward merchant profitability; JD.com entered food delivery/quick commerce (JD Instant Delivery vs Taobao Flash Sale); China live-commerce GMV crossed ¥5 trillion (Douyin ~28%, Taobao Live <20%); Pinduoduo "rebuild another Pinduoduo in three years" plus a ¥100-billion+ supply-chain investment; Alibaba pivoted to AI/cloud as a second curve.
