Both are definitely in to retail. The are not market places like so that is a difference. (they both have physical and virtual stores where they sell both physical and virtual products and both own-brand as well as third party) If companies are afraid of other companies looking at their stuff they are essentially going to have to reinvent everything themselves. What about transactions, imagine someone checking what they pay their supplier and what the customer is paying, that'd be scary. So now you can't use off-the-shelf cash registers, banking services, ERP systems etc. The only difference people are trying to see is that AWS and Amazon Marketplace both have Amazon in the name. They don't have the same people, the same building or the same anything, except the same Bezos at the top.
