Mega-cap stocks represent the largest publicly traded companies, distinguished by their substantial market capitalization and industry dominance. Typically, a company qualifies as a mega-cap if its market valuation exceeds **$200 billion**. Walmart firmly fits this classification, consistently maintaining a market cap above **$700 billion**. Its strong financial performance, expansive retail network, and leadership in e-commerce reinforce its status as a leading mega-cap stock. Investors and analysts closely monitor Walmart’s valuation.
