USDT dominates commerce payments with $95B in H1 2026 identified transactions, while USDC leads DeFi and trading activity, showing stablecoins are segmenting by use case.
DeFi & Yields ·
Stablecoins are segmenting by use case based on transaction patterns in the first half of 2026. USDT processed approximately $95 billion in identified commerce payments during that period, while USDC dominated activity in decentralized finance and trading venues. The divergence suggests each stablecoin is consolidating volume in distinct economic layers rather than competing uniformly across all applications.
The split reflects how different user cohorts—merchants, traders, and protocol participants—have adopted stablecoins for their respective needs. Commerce flows concentrate on USDT, likely due to its liquidity and acceptance among payment processors and retailers, whereas USDC's strength in on-chain trading and lending protocols indicates institutional and developer preference in those segments. This pattern may persist if network effects and integrations continue to favor each coin's existing strongholds.
What remains unclear is whether this segmentation will stabilize or shift with regulatory changes, new entrants, or infrastructure improvements. The data captures only identified transactions, so actual volumes flowing through privacy-preserving or untracked channels are unknown. Long-term sustainability of these use-case divisions will depend on how each stablecoin's operational and technical capabilities evolve relative to user demands.
