USDC's share of stablecoin transactions is slipping, while USDT is gaining ground and leading in volume.
BitPay data shows USDC's share dropped from 85% to 56%, with USDT surging to 43% by May 2025.
Despite USDC's strong regulatory positioning and recent public listing, USDT has taken the lead in transaction volume on BitPay.
Tether's growing adoption on payment platforms suggests that the competition between USDT and USDC is ongoing, with USDT remaining the largest stablecoin by overall valuation.
