Stablecoins are now processing more adjusted volume each month than major payment networks such as Visa and PayPal, according to Delphi Digital. The firm described stablecoins as “the most important infrastructure story in crypto” due to rapid growth in usage and supply.
Notably, by October, monthly adjusted stablecoin transaction volume climbed to $1.5 trillion. For comparison, Visa and Mastercard recorded network spending volumes of $4.4 trillion and $2.7 trillion, respectively, during the third quarter of 2025.
This places the stablecoin market ahead of individual consumer payment platforms.

Delphi argued that previous fintech waves improved the user experience but left the underlying payment structure mostly unchanged. Digital banks and payment apps made transfers easier, but transactions still moved through the same chain of intermediaries involving merchants, acquirers, card networks, and issuers.
However, stablecoins settle transactions directly onchain. This removes several layers from the process and shortens settlement times. According to Delphi, this shift is the primary reason behind the recent stablecoin growth, particularly in cross-border payments.
Regulation has also played a major role in the sector’s rise. The GENIUS Act, passed in July, introduced a federal framework for dollar-backed stablecoins in the US. This regulatory clarity encouraged banks, payment firms, and tech companies to act more quickly.
Despite the growing list of issuers, the market remains concentrated. Tether holds about 60% of the stablecoin supply, with roughly $186 billion in circulation. Circle’s USDC USDC $1.00 24h volatility: 0.0% Market cap: $77.98 B Vol. 24h: $13.62 B follows with a 25% share and a market cap near $78 billion.
Since the Oct. 11 market crash, Tether and Circle have combinedly issued over 20 billion in new stablecoins as of early December, according to Lookonchain. Together, the two account for about 85% of the total stablecoin market cap, which exceeds $315 billion, based on CoinMarketCap data.
