Stablecoin transaction volume has exceeded $30 trillion annually, reflecting the massive volume of value moved on-chain. USDC has emerged as the preferred choice for institutions, accounting for 55% of the market’s activity.
While the total stablecoin market capitalization remains around $315-$320 billion, the surge in transaction volume to over $30 trillion is largely due to the asset’s transition from a speculative trading tool to a foundational financial infrastructure for settlement and treasury operations. Adoption has been accelerated by the U.S. GENIUS Act (2025) and Europe’s MiCA framework, which have provided the legal certainty required for major banks and Fortune 500 companies to integrate stablecoins into their workflows.
Meanwhile, Circle’s USDC is outpacing Tether’s USDT (~$13.3T) in transaction volume despite having a smaller circulating supply (~$ 77- $78B USDC vs. ~$188B USDT). Specifically, Visa has integrated USDC for settlement and expanded its stablecoin-linked card products to over 100 countries.
Kyriba recently integrated USDC into its treasury platform, allowing corporate finance teams to manage digital dollars within standard enterprise workflows. Coinbase has also partnered with Nium to enable institutional clients to settle cross-border B2B payments in USDC.
USDC silently becomes crypto payments’ workhorse
USDC has quietly become the workhorse of crypto payments, accounting for roughly 70% of “real” on-chain transaction volume in February 2026 (approximately $1.26T vs. USDT’s $514B). USDC is winning the settlement game despite USDT having more raw volume (due to high-frequency trading) because institutions use it to move value, not just speculate. USDC reached ~$38 billion in Q1 2026, with 78% YoY growth in circulation.
Reveel, backed by YZi Labs (formerly Binance Labs) with a direct interest in promoting USDC usage, also claimed that USDC processed approximately $8.3 trillion in stablecoin transfers in January. The stablecoin tooling startup further noted that USDT accounted for roughly $1.7 trillion over the same period, with a supply more than double that of USDC. That proves USDC’s velocity: each USDC unit is being used nearly 90 times more frequently for actual payments than its competitors.
Meanwhile, USDC’s dominance is also driven by MiCA (EU) and the GENIUS Act (U.S.), which have forced regulated entities to abandon non-compliant stablecoins for treasury operations. USDC has grown its throughput 6.8x in just one year as the regulated rail for institutional finance, hitting nearly $9.6 trillion in a single quarter.
USDC gains traction through partnerships, enables fiat-like experiences
USDC is gaining traction by forming partnerships that enable fiat-like experiences. Shoppers pay in stablecoins, while merchants receive local currency to avoid the risks of forex exposure. USDC’s programmability supports automated payouts and smart contract integrations for supply chains. Stripe re-enabled USDC acceptance and launched stablecoin financial accounts in over 100 countries.
USDC’s multi-chain support (including Solana for fast settlements) also enhances the stablecoin’s utility in high-frequency retail scenarios. USDC is not competing with USDT for the same users, it is building a parallel financial rail for a different category of money movement entirely.
Meanwhile, Circle is also pivoting from being just a stablecoin issuer to an infrastructure provider with the launch of Arc. The permissionless, KYC-compliant layer is designed specifically for banks and enterprises to settle with each other using USDC.
Consequently, USDC has effectively become the “HTTP of money” for the regulated world. Treasury managers and CFOs are using USDC to optimize working capital, reducing the settlement process from days to seconds. Liquidity providers like Wintermute, Cumberland, and Flowdesk make up the invisible layer that makes real-time settlement actually work.
BlackRock is also acting as a “repo bridge” through its BUIDL fund and partnerships with Securitize. The company is creating a new “on-chain repo market” by using USDC rails to allow institutions to move liquidity in and out of tokenized Treasury bills 24/7. These companies have integrated USDC into their backend infrastructure, treating it as a settlement layer to bypass cross-border friction.
