USDC, the stablecoin issued by Circle, has reached a remarkable milestone with its total supply surpassing $81.1 billion—setting a new all-time high for the digital dollar token. For the first time since 2019, USDC has outpaced Tether’s USDT in transaction volume, signaling a significant shift in stablecoin market dynamics. This development suggests that regulatory compliance and transparency are increasingly influencing institutional preferences, sometimes even outweighing USDT’s well-known liquidity advantage.
Relentless Rise in USDC Supply
Launched by Circle in 2018, USDC is a regulated stablecoin backed by reserve assets and subject to auditing, making it a preferred “digital dollar” in global markets. It surpassed the $25 billion supply mark during the 2021 bull run and climbed to $55 billion in 2022. Despite a correction in 2023, USDC rebounded strongly, eclipsing all prior records by early 2026 at $81.1 billion in circulation. While Ethereum remains the dominant network for USDC, recent years have seen accelerated adoption on blockchains like Solana, Arbitrum, Base, Polygon, Sui, and the up-and-coming HyperEVM.
Transaction Volumes Redraw the Landscape
Alongside its supply surge, USDC has reached critical mass in transaction volumes as well. In early 2026, the adjusted transaction volume of USDC soared to roughly $2.2 trillion, leaving USDT trailing at $1.3 trillion for the same period. In February alone, USDC accounted for nearly 70% of $1.8 trillion in stablecoin transfer activity. The turnover rate for individual USDC tokens far exceeds that of USDT, pointing to broader use in active transactions and payments. Despite taking the lead in transaction flows, USDC still lags behind USDT’s $185 billion market capitalization.
Key Drivers of Institutional Adoption
Three core factors have been instrumental in shaping the stablecoin choices of global financial institutions. First and foremost is regulatory alignment. USDC’s compliance with both the GENIUS Act in the US and MiCA (Markets in Crypto-Assets) in Europe has made it especially attractive for institutions navigating complex regulatory frameworks. The recent MiCA licensing of platforms such as SwissBorg, Relai, and Blockchain.com in Europe has further accelerated this institutional pivot towards USDC.
The second decisive factor is the surge in artificial intelligence-driven and automated financial applications leveraging USDC. Circle revealed that, in 2026, a staggering 98.6% of payments facilitated by AI-based systems were settled in USDC, with over 140 million discrete transactions carried out by autonomous entities.
Circle emphasized in a statement, “Virtually all payments executed by autonomous systems were finalized using USDC, and this new demand segment continues to grow rapidly year after year.”
Thirdly, the integration of USDC into traditional finance is reshaping the stablecoin’s corporate profile. Heavyweights like Visa, Mastercard, and BlackRock have unveiled new payment and settlement solutions built around USDC, helping drive a sharp uptick in institutional transaction volume.
Market Outlook for Circle
Following its listing on Nasdaq under the CRCL ticker, Circle Internet Group has attracted close scrutiny from market watchers. Brokerage Bernstein raised its 12-month target for Circle shares to $190 in March, emphasizing Circle’s growth prospects in payments and corporate services. William Blair echoed this positive sentiment, underscoring the company’s financial resilience and increasing market interest in its business model.
Yet, a gulf remains between Bernstein’s bullish target and Mizuho’s more cautious $120 price forecast, highlighting ongoing uncertainty about Circle’s future valuation. Because a significant share of Circle’s revenue comes from interest on reserve assets, shifts in interest rates can have a direct impact on profitability. Bernstein analysts noted, however, that rising transaction volumes—especially from AI-driven payments and institutional use cases—could over time yield more stable revenue streams.
The milestone of crossing $81.1 billion in supply, along with the changing of the guard in transaction volume leadership, underscores USDC’s strengthening position in both the financial sector and the expanding world of digital payments.
