“Can the Amazon Business + Mastercard partnership become the end-to-end financial operating layer for SMB procurement — spanning card issuance, open banking data, reconciliation, and retirement — on top of Amazon's existing B2B marketplace?”
Amazon Business, launched in 2015, is Amazon's B2B marketplace offering business customers purchasing tools, analytics, and payment flexibility. The 'Mastercard Amazon Business' entity specifically refers to the partnership between Amazon Business and Mastercard — most prominently the co-branded Prime Business Card and Amazon Business Card issued by U.S. Bank on the Mastercard network, launched in May 2026. Separately, Mastercard's subsidiary Finicity provides open banking (consumer-permissioned data) services connecting users' financial accounts with Amazon. The embedded finance stack spans card issuing, open banking data, spend management, and reconciliation APIs aimed at streamlining B2B procurement.
