Walmart.com is wholly owned by Walmart (it is merely a division of Walmart, actually, and not a separate entity of any sort), and we're talking about market cap, so...according to this article, Amazon is worth more than Walmart and Walmart.com.

Walmart.com revenue/worth is a tiny, tiny fraction of the whole Walmart.

yes the measure they are talking about is market cap, not sales. the market cap for Wlmt includes sam's club, walmart.com, etc.

In terms of total sales, Wlmt (including subsidiaries) is close to $500B, while Amazon is approaching $100B. However, Wlmt.com (domestic) is only ~2% of total sales times $288B total domestic sales so only ~$5B sales

Is walmart.com owned by a different company?
