Group 2: Competitive Landscape - Walmart faces increased pressure from Amazon's aggressive expansion, which may lead to price wars and rising costs, impacting profitability in the e-commerce sector [3][6]. - Walmart's recent decision to open its shopper data to multiple advertising platforms enhances its ability to attract advertisers and compete with Amazon's advertising business, which grew by 23% year-over-year to $15.69 billion [3][6]. - Despite challenges, Walmart's membership program showed double-digit growth in the last quarter, indicating potential resilience [3].
