Block operates two interconnected fintech ecosystems: Square, which serves businesses, and Cash App, which serves consumers. Square is a commerce platform for sellers of all sizes, offering payments hardware, point-of-sale software, payroll, inventory management, customer loyalty, business banking, and lending. Square serves over 4.5M sellers, processing $250B in gross payment volume in 2025, with a core focus on small businesses and a growing push upmarket toward mid-market sellers. Cash App is a consumer financial super-app with 59M monthly transacting actives, offering peer-to-peer payments, a Visa debit card, stock investing, bitcoin trading, short-term loans, and BNPL through its Afterpay integration. Cash App targets consumers underserved by traditional banks, with a particular focus on millennials, Gen Z, and households earning up to $150K per year. Block generates revenue through payment processing fees (a percentage of each transaction), lending and banking fees, and bitcoin trading spreads. The lending business is notable: Cash App Borrow uses real-time transaction data for underwriting, with loans typically repaid in under 30 days. Block sells most Square loans to third-party investors, managing credit risk off its balance sheet. Block's growth strategy focuses on deepening Cash App's banking relationships, expanding Square upmarket via field sales, and connecting both ecosystems through its "Neighborhoods" initiative, which uses Cash App's consumer network to drive traffic to Square merchants.
