TikTok Shop was the fastest-growing ecommerce platform globally in 2025, though conflicting Chinese media reports claim 2025 GMV "approached US$100B" — see Section 10 conflict note (https://api3.cls.cn/share/article/2250190?os=ios&sv=218&app=stib">cls.cn, https://hk.investing.com/news/stock-market-news/article-1258159">Investing.com HK, https://m.sohu.com/a/973427549_161795">Sohu). - Instagram / Facebook Shops — no standalone 2025 revenue figure surfaced; platform is covered in market reports above.

2. Live Commerce

China (the dominant market) - China's live-commerce market is ~US$900B and now approaches the scale of the entire US e-commerce market (NielsenIQ, 2026 press release). https://nielseniq.com/global/en/news-center/2026/chinas-900b-live-commerce-market-now-approaches-us-e-commerce-scale/">NielsenIQ, https://finbets.websol.barchart.com/?module=topNews&storyID=3333180&symbol=&selected=news">AP/Barchart - Platform split (China): Douyin captured 31% share of China live-commerce GMV, surpassing Taobao for the first time (BXTData analysis). Note: BXTData's headline figure "GMV exceeds 52 trillion CNY" is almost certainly a typo/scale error (52 trillion CNY ≈ US$7T would exceed all of China's retail); the credible read is ~5+ trillion CNY (~US$700B–900B), consistent with the NielsenIQ ~$900B figure.

10. Conflicts & Caveats (flagged)

TikTok Shop 2025 GMV: US$64.3B (+94%, AMZ123/Tabcut-style data) vs "approaching US$100B" (Chinese financial media, Jan 2026). The ~$100B figure may include gross-merchandise-value definitions incl. non-US markets or be promotional; treat US$64B as the more conservative, datapoint-specific figure.
China live-commerce scale: BXTData's "52 trillion CNY" is not credible as stated (≈US$7T); the reliable anchor is NielsenIQ's ~US$900B (2026). Use ~US$900B / 5–6T CNY.
Social commerce market size: vendor estimates differ wildly because of scope (platform GMV vs. ad-adjacent sales vs. "social-driven" sales). No single authoritative global figure; the "$1.2T" framing is a secondary citation.
Amazon GMV 2025: Marketplace Pulse says ">$800B"; Chinese coverage says ~US$830B and ~70% third-party. Minor definitional variance (retail vs marketplace GMV).
eMarketer share of retail: ">20% of worldwide retail sales" — vintage 2025-2026; slower growth vs 2021-2022 boom.
BNPL: US$560B (The Paypers) vs Worldpay GPR 2026 trend coverage (which emphasizes growth trajectory rather than a single level); vendor forecasts vary widely — treat US$560B as a recent anchor.
Walmart e-commerce: "~$150B" is from April 2026 coverage of FY26/FY27 performance; Walmart's own reported e-commerce growth is ~20%+ per quarter but dollar definitions (global vs US) vary.
