Woofun AI data shows that Circle's USDC represented approximately 70% of the adjusted stablecoin transaction volume during the first half of 2026, widening its advantage over Tether's USDT, which held a 25% share. This metric excludes bot activities and non-economic blockchain transfers to reflect genuine economic usage.

Total adjusted stablecoin trading volume for the first six months reached $8.82 trillion, exceeding the full-year 2024 total of $5.8 trillion but remaining below the $10.8 trillion record set in 2025. June alone saw volume surge 63% month-over-month to a record $1.79 trillion. Financial institutions like Standard Chartered and BNY Mellon are increasingly integrating USDC for payments and settlements, continuing a trend where USDC's share has grown from under 10% in 2020 to 45% in 2022.
