As of 2019 Walmart has 11,776 stores around the world and brings in billions of dollars in profit monthly and yearly.
Walmart Started out as a small store in Bentonville Ar and from them on expanded into more stores and now they've grown to become one of the biggest retailers both online and offline.
However Amazon is outpacing Walmart by a huge amount and more people order on Amazon than they do go buying online at Walmart or in their stores.
Walmart has closed some stores in some locations but it will be a very long time if ever that Walmart closes down for good.
Walmart would likely be sold to another owner before it ever shut down completely because the stores are bringing in money.
