1. Market size & growth

Five things the Index reveals
- The Chinese duopoly is bigger than everything else combined. Taobao+Tmall + Pinduoduo together are larger than the entire rest of the top 25.
- Marketplace growth is bimodal. Mature platforms grow single digits. New entrants grow 30-200%.
- B2B is where the next $1B+ marketplaces will come from. Mirakl Connect, GigaCloud, Faire are the tip of a $30T+ TAM.
- Take rates are a noisy signal. TikTok Shop and Mercado Libre have similar headline rates but radically different cost-to-serve.
- The Mirakl cohort is a leading indicator. When 30+ enterprises cross $100M GMV in one year, retailers have stopped competing with marketplaces and started becoming them.

10. Seven takeaways for marketplace operators in 2026
- The marketplace model has won. ~30% of all global consumer spending - and 69% of European cross-border ecom - flows through marketplaces. Single-vendor DTC is now the niche.
- The fastest growth is in B2B + enterprise marketplaces. B2B ecom is on track to nearly 2x by 2029. Mirakl-powered enterprise marketplaces grew 4x faster than ecom overall in 2024.
- Multi-homing is the seller default. 42% of sellers operate on 4+ platforms. Sellers on 2+ platforms generate 17.5x the GMV of single-channel sellers. If your platform requires exclusivity, you'll lose your best sellers.
- AI catalog automation is now the highest-leverage seller productivity tool. +88% GMV uplift from AI tagging/listing vs manual. This is no longer optional.
- TikTok Shop and Temu didn't replace Amazon - they expanded the pie. 97% of TikTok Shop buyers also use Amazon. The new entrants are pulling time + dollars out of social media, not stealing them from existing marketplaces.
- Take rate inflation is real but measured. Mirakl-marketplace average take rates rose from 14.1% → 14.7% in one year. Sellers are tolerating it because GMV is growing faster than commissions.
- Build-vs-buy is settled for everyone except enterprises. SaaS at $75-$385/mo solves 95% of new marketplace launches. Custom build only justifies itself for highly specialized logistics or vertical workflows.
