The monthly transaction volume for cryptocurrency-linked cards reached a significant milestone of $600 million in March 2026, representing a more than threefold increase from the $187 million recorded in March 2025. This steady climb highlights the growing mainstream adoption of crypto debit and prepaid cards, which enable users to spend digital assets directly at point-of-sale terminals, bypassing the often cumbersome traditional off-ramp infrastructure.
Throughout this period of explosive growth, Tether's USDT has been the dominant settlement currency, consistently accounting for the majority of crypto card volume. This dominance aligns with Tether's entrenched position in emerging markets across Southeast Asia, Latin America, and Africa, where crypto cards frequently serve as a more accessible alternative to conventional banking systems.
However, a notable shift is underway. USDT's market share has been gradually compressing as Circle's USDC gains ground. This growth is largely driven by adoption in Western markets, where regulatory clarity and institutional backing carry significant weight with both card issuers and users. The stablecoin composition of card volume is now viewed as a key indicator of geographic and demographic shifts within the crypto user base.
A rising share for USDC would suggest the user base for crypto cards is broadening beyond Tether's traditional strongholds in emerging economies. In response to this competitive pressure, Tether has signaled its intention to introduce a U.S.-focused stablecoin product. If successful domestically, this move could potentially slow or reverse USDC's share gains in the very region where its growth has been most pronounced.
