I think Amazon is very much on another level in terms of scale. Not trying to be negative about Shopify — they have a very large system to maintain - but Amazon is just on another level.

Amazon don't seem release any figures but I've seen estimates of 50,000 to 100,000 engineers. They do have 1.576 million employees worldwide (2025 figure).

Yes but “Amazon-scale infra” as the grandparent mentions should absolutely include AWS, and Shopify is nowhere near that size.

Combined Shopify sales are ~half of Amazon's but growing quicker. Shopify probably supports more sales per engineer than Amazon's retail stack team.

Amazon also has AWS as infra though, they only do retail as a side gig

They also have enormous fulfillment services. Shopify doesn't handle that part.

They also have video and music streaming. And Kindle Unlimited.

Shopify is not far behind Amazon (the e-com business). It's network sees as many unique visitors as Amazon, though I imagine Amazon has more sessions per visitor, but the GMV across Shopify is just shy of half of Amazon. It's still in the same ball park.

What metic are you using? Shopify takes an average of ~$1bn at checkout daily while Amazon is over 2bn.

Yes, Shopify GMV is roughly half of Amazon.
