Mastercard's Marc Pettican on the road to a $17.4 trillion virtual card market
Every account payable and account receivable department runs on the same friction: invoices chased four or five times, payments late more than 30% of the time, and credit control teams that can run 20, 30, even 50 people deep at a mid-sized corporate. Virtual cards were built to solve exactly that problem, and the growth numbers show it — spend is projected to hit $17.4 trillion by 2029, according to Juniper Research. Today I'm joined by Marc Pettican, global head of corporate solutions at Mastercard, who's spent decades working both sides of the payments ecosystem, from the merchant acquiring side to leading commercial cards. We get into what's really driving virtual card growth beyond the macro tailwinds, how MasterCard balances network economics between buyers and suppliers, and the build-versus-partner calculus behind expanding from travel into verticals like fleet and logistics, healthcare, insurance, and marketplaces. We also dig into embedded finance and the challenge of staying visible in the stack even as payments become invisible to the end user — plus where Mastercard sees its right to win in agentic payments, account-to-account transfers, and stablecoins. Marc closes with his advice for commercial card heads at mid-sized banks over the next twelve months.
