  • Examine the size of the US ecommerce market by leading retailers’ market share.
  • Identify key shifts in market share between 2025 and 2027.
  • Isolate the white-space sales opportunities for smaller retailers.

Key use cases:

  • Determine market sizing (brands, retailers, and solution providers)
  • Develop go-to-market strategy and showcase opportunities to customers (solution providers)
