Retail

The retail sector, with a global TAM exceeding $30 trillion in 2025 and projected to reach $40+ trillion by 2030-2031 at a 6-8% CAGR, remains a cornerstone of the consumer economy driven by population growth, rising middle-class spending in emerging markets, e-commerce penetration, and omnichannel innovation. Walmart, Amazon, and peers dominate through scale advantages in supply chain efficiency, data-driven personalization, and value positioning amid inflationary pressures. The key tension lies in the ongoing disruption between traditional brick-and-mortar models facing margin compression and e-commerce giants capturing share, alongside debates over market concentration, labor costs, and the resilience of physical retail in a digital-first world.

• Companies primarily engaged in selling merchandise (physical or digital) directly to consumers for personal or household use
• Brick-and-mortar stores, e-commerce platforms, warehouse clubs, and discount/off-price retailers
• General merchandise, grocery, home improvement, and apparel-focused retail operations
• Omnichannel retailers blending online and physical presence

• Pure wholesale distributors or B2B suppliers not selling directly to end consumers
• Restaurants, hospitality services, and automotive dealerships (often classified separately)
• Software platforms or pure logistics providers without direct retail sales
