The total supply of stablecoins climbed to a new high of $315 billion in the first quarter of 2026, increasing by around $8 billion despite a broader slowdown in the crypto market. Beneath this growth, market dynamics are shifting, as USDC rapidly gains ground on USDT. USDC’s supply has surged to roughly $78 billion since late 2023, fueled largely by institutional use cases such as business settlements, payroll systems, and automated payment infrastructure developed by major financial platforms. Meanwhile, USDT remains the largest stablecoin by total supply but is gradually losing market share.
Stablecoins also dominated trading activity, accounting for 75% of total crypto volume during the quarter, with transactions exceeding $28 trillion—surpassing traditional payment giants.
The rise of USDC is closely tied to regulatory positioning and institutional adoption rather than retail demand, with transaction patterns showing frequent, smaller transfers typical of automated financial operations. At the same time, algorithmic activity now represents the majority of stablecoin flows, reducing the influence of retail-driven usage that once supported USDT’s dominance.
