Gross merchandise value (GMV) is the total value of everything sold through a marketplace or e-commerce platform in a period — the sum of all transactions at their face value, before deducting refunds, discounts, seller payouts or the platform’s own commission. A marketplace where sellers moved ₺500M of goods has ₺500M GMV even if the platform itself earned only ₺40M. GMV measures the size of the economy a platform hosts; revenue = GMV × take rate measures the platform’s share of it.
GMV is genuinely useful — it tracks scale, liquidity and growth momentum in businesses whose revenue line alone understates their footprint. It is also the most gamed number in e-commerce: bookings counted before cancellations, gross-of-returns figures in high-return categories like fashion, “GMV” that quietly includes the company’s own first-party sales. Sophisticated readers always ask three questions: is it net of cancellations and returns, what take rate converts it to revenue, and is GMV growth outpacing or lagging marketing spend.
Diligence and disclosure angle
In transactions, GMV definitions become contractual. Earn-outs and valuation covenants tied to “GMV” require a precise, audited definition — net or gross of returns, test purchases, fraud — or they end in disputes. In diligence, advisers reconcile claimed GMV to payment-processor settlement data, the cleanest external check. Public communication carries its own discipline: regulators have repeatedly pressed e-commerce companies on GMV-forward presentations that obscure revenue economics, so investor decks should label GMV, revenue and take rate explicitly rather than letting the largest number do the talking.
