The rapid expansion of digital dollar assets for corporate settlement makes the shifting landscape of blockchain-based transaction volumes highly critical for global financial institutions monitoring market share.
Key Takeaways
- Circle's USD Coin (USDC) secured a 70% share of adjusted onchain transaction volume during the opening six months of 2026.
- Adjusted stablecoin activity across public networks peaked at a record $1.79 trillion during June 2026.
- The current volume distribution marks a reversal from the year 2020, when Tether (USDT) controlled nearly 90% of all organic transaction volume.
- Total adjusted stablecoin transaction volume for the first half of 2026 reached $8.82 trillion, outpacing prior yearly records.
USDC Dominance
Circle’s USDC token has established a substantial lead over its primary competitor by capturing approximately 70% of the total adjusted stablecoin transaction volume during the first half of 2026. According to data published on the Visa Onchain Analytics Dashboard, Tether’s USDT represented roughly 25% of the adjusted economic throughput over the same six-month timeframe. This distribution highlights a divergence between total market capitalization and actual transaction velocity, as USDT maintains a higher circulating supply while USDC commands the majority of settlement utility.
Massive Volume Spike
Onchain data reflects an accelerated expansion of stablecoin utilization, with adjusted monthly transaction volumes growing to a record-breaking $1.79 trillion in June 2026. This metric represents a 63% month-over-month increase when measured against the $1.1 trillion calculated during May 2026. According to a report by CoinDesk, the June 2026 figure also marks a 125% year-over-year increase compared to the $795 billion in adjusted volume documented in June 2025.
Historical Market Shift
The transactional data from the first half of 2026 completes a multi-year structural inversion of market dominance between the two leading fiat-pegged tokens. In the year 2020, USDT accounted for nearly 90% of the adjusted network transaction volume, whereas USDC accounted for less than 10% of that specific metric. Historical tracking from Visa Onchain Analytics indicates that by the year 2022, USDC had expanded its share to approximately 45% of adjusted transaction volume, establishing the trajectory toward its current 70% market position.
Record-Breaking Year
The cumulative transaction volume calculated between January 2026 and June 2026 has put the digital asset sector on track for an unprecedented fiscal year. The six-month total of $8.82 trillion in adjusted volume has already surpassed the $5.8 trillion recorded during the entirety of 2024. Data published by KuCoin News indicates that this first-half performance leaves the industry only $2 trillion short of matching the all-time calendar record of $10.8 trillion reported across the full 12 months of 2025.
Institutional Driving Force
The expansion of transaction velocity is primarily supported by traditional banking corporations integrating public blockchain networks directly into their settlement systems. Global banking groups, including BNY and Standard Chartered, have added custody and transactional services centered around Circle's USDC framework. According to analysis published by The DeFi Report, these tier-one financial institutions are choosing to deploy capital through existing, highly liquid stablecoin networks to manage payments and corporate treasury operations rather than deploying resources to build proprietary payment rails.
