“Can a closed-loop card network become the AI-powered financial and expense operating system for global commercial customers?”
Amex evolved from a 19th-century freight company into a global payments network and issuer-acquirer, distinct from Visa/Mastercard via its closed-loop three-party model. In recent years it has pivoted aggressively from a pure card issuer into a commercial financial-services platform: building out Business Blueprint (loans, lines of credit, working capital), Amex Sync as a B2B partner-API program, and acquiring Kabbage (2020), Center (2024), and Hyper (2026) to extend into SMB banking, expense management, and agentic AI. Open Banking via 'Pay with Bank transfer' in the UK signals a willingness to embrace account-to-account rails alongside its card network. The recent shutdown of Global Pay shows it is rationalizing the SMB cross-border bet.
