AI Payment Platforms Target False Declines Reported by 56% of U.S. Consumers

False payment declines occur when fraud controls reject legitimate purchases, costing merchants an immediate sale and potentially weakening customer loyalty. An earlier PYMNTS Intelligence study found that 56% of U.S. consumers had experienced such a rejection within the previous three months. The commercial risk extends beyond authorization: 42% of consumers abandon their carts after a payment failure, making approval performance a key revenue and retention metric.

PYMNTS on Sept. 2, 2026, highlighted the August edition of its “Optimizing Payments Tracker,” which said 83% of respondents reported that AI had meaningfully reduced false positives and related churn over the previous year. Mastercard research cited in the report found that 42% of issuers and 26% of acquirers had each blocked more than $5 million in attempted fraud over two years using AI. Meanwhile, 69% of companies using core orchestration tools achieved approval rates above 97%, while processing fees could fall by as much as 30%.
