Global E-Commerce Market Size for 2025 Splits Sixfold -- From $5.5T to $33.9T Depending on Scope
Analyst estimates of the global e-commerce market for 2025 range from $5.5 trillion (IMARC Group's B2C-only figure) to $33.91 trillion (Grand View Research's broader estimate that folds in business-to-business transactions). eMarketer's retail-focused estimate sits closer to the low end at $6.419 trillion, or 20.5% of total global retail sales. The spread is less about disagreement on consumer shopping trends and more about scope -- whether a report counts only consumer retail purchases, all B2C digital commerce, or the far larger volume of B2B e-commerce between businesses.
Findings
- eMarketer projects global retail e-commerce sales will reach $6.419 trillion in 2025 -- 20.5% of total global retail sales, up from 19.9% in 2024.
- IMARC Group puts the global B2C e-commerce market, a broader category than pure retail that can include services and travel bookings, at $5.5 trillion for 2025.
- Grand View Research's $33.91 trillion 2025 estimate for the 'global e-commerce market' is roughly 5-6x eMarketer's retail figure -- consistent with UNCTAD's finding that B2B e-commerce sales (~$27 trillion as of 2022) dwarf consumer B2C volume.
- None of the three headline market-size figures state their B2B/B2C/retail scope prominently in the topline number -- a reader comparing 'the e-commerce market size' across reports without checking methodology could reasonably conclude the market is either $6 trillion or $34 trillion.
