Gross Merchandise Value (GMV)

Gross merchandise value represents the total dollar amount of all transactions facilitated through a platform. For marketplaces like Amazon, Etsy, or Shopify stores, GMV captures the total volume of commerce flowing through the platform. It is a measure of scale and market activity, not actual revenue, since the platform typically keeps only a percentage as commission or fees.

GMV is useful as a growth metric for marketplaces because it captures total commercial activity regardless of the platform's take rate. A marketplace with $10M GMV and a 15% take rate generates $1.5M in actual revenue. Investors track GMV growth to understand the platform's market penetration and then analyze take rate to understand monetization efficiency.

The danger of GMV is that it can be misleading when used as a proxy for business health. A marketplace could grow GMV by subsidizing transactions, attracting low-quality sellers, or counting cancelled orders. True platform health requires looking at GMV alongside net revenue, take rate, buyer retention, and seller quality. GMV is an important input, not a complete picture.
