A commonly-appearing clickbait ad suggests that Walmart is shutting down completely:
Given that Walmart is one of the world's largest companies, this would indeed be big news if it appeared anywhere other than on a block of links that exist solely for the purpose of generating low-quality ad revenue.
Clicking the link takes you to a completely unrelated 26-page slideshow story about "Stores That Are Closing Locations Across The Country." This article does not, in fact, mention Walmart once.
Because Walmart has no plans to close all of their stores, the implication made by this clickbait ad is "False."
