This title is very misleading. Shopify has surpassed eBay in market cap, but is in a very different business. Same wrt amazon. Conflating market cap with market ownership is just confusing.

However, I really hope Shopify can figure out a way to make it easy to find quality sellers and replace Amazon’s dumpster fire of a third party marketplace. Trying to buy electronics or household products on amazon is a complete crapshoot these days.
