What is Amazon, who is it strong for?

Amazon leads US e-commerce; it offers massive buyer traffic, mature FBA logistics and an advanced ad ecosystem. Its edge is scale and infrastructure; the downside is intense competition and rising ad costs. Ideal for brands seeking volume and speed that can build a strong listing and review profile.

What is Walmart Marketplace?

Walmart Marketplace is younger than Amazon but growing fast. Fewer competing sellers and cheaper ads give early movers an edge. WFS (Walmart Fulfillment Services) logistics is maturing. The approval process is more selective, which limits crowding.

Key difference: competition vs maturity

Amazon is mature and crowded; strong ads and listings are required to be visible. Walmart is less crowded but its infrastructure is still developing. The healthiest strategy is often running both — building volume on Amazon while positioning early on Walmart.

Who should choose Amazon?

  • Those wanting maximum volume and speed
  • Those who can set up fast delivery via FBA
  • Those with strong listing + review profiles
  • Those seeking broad category reach

Who should choose Walmart?

  • New brands seeking lower competition
  • Those wanting to cut ad costs
  • Those seeking an early-mover advantage
  • Those diversifying after saturating on Amazon

Common mistakes

  • Treating it as either/or; for most brands, both together is best
  • Underestimating Walmart and missing the early window
  • Trying to compete on Amazon with a weak listing
  • Starting without planning logistics (FBA/WFS)
  • Pricing without converting fees and ads to net profit

Frequently asked questions

Is Amazon or Walmart more profitable?

It depends on margin; Walmart's cheaper ads can mean higher early margins, while Amazon scales with volume.

Can I sell on both at once?

Yes, and it's recommended for most brands; multi-channel selling with tools that manage stock and listings centrally is healthy.

Is it hard to get on Walmart?

Its approval is more selective than Amazon's, which turns into an advantage by limiting competition.
