After years of USDT dominance, Circle’s USDC has taken the lead in meaningful on-chain activity.
This marks the first time since 2019 that USDC has surpassed Tether’s USDT in adjusted transaction volume.
Blockchain analytics firm Allium reported a record $1.8 trillion in total stablecoin transfer volume for February 2026. USDC accounted for $1.26 trillion (about 70%) while USDT handled $514 billion (Cointelegraph, citing Allium, March 7, 2026).
Mizuho Securities backed the shift in a March 13 note: year-to-date adjusted volume reached USDC $2.2 trillion versus USDT $1.3 trillion, giving USDC about 64% of combined adjusted flows (Bitcoin.com, citing Mizuho).
Key Takeaways
- USDC handled $1.26 trillion of February 2026's record $1.8 trillion stablecoin transfer volume, about 70%, against $514 billion for USDT (Cointelegraph, citing Allium).
- Mizuho counted $2.2 trillion of USDC adjusted volume versus $1.3 trillion for USDT through March 13, 2026, about a 64% share (Bitcoin.com).
- The lead did not hold: USDT carried 84% of stablecoin payment value from January to September 2026 (Allium Q3 2026).
- USDC supply peaked at about $79.6 billion on March 18, 2026 and was about $71.3 billion on October 27, 2026 (DefiLlama).
- Total stablecoin supply ended September 2026 at $305 billion, just 0.4% above January (Allium).

→ Keep in mind that adjusted volume removes wash trading and internal cycling to reflect genuine economic use in payments, settlements, DeFi, and institutional transfers.
Here are the five key reasons behind USDC’s decisive momentum:
1. Post-GENIUS Act Regulatory Clarity and Institutional Preference
On February 25, 2026, the Office of the Comptroller of the Currency (OCC) proposed its GENIUS Act rule, covering licensing, capital, reserves, redemption and oversight for issuers, with comments due May 1 (OCC). The OCC has since finalized the rule, effective January 18, 2027 (OCC).
This clarity has accelerated adoption by corporations, fintechs, and institutions that prioritize auditability and regulatory alignment.
USDC’s transparent monthly attestations and full reserve reporting give it a measurable compliance premium, making it the preferred rail for treasury management, B2B settlements, and enterprise workflows.
USDT retains strength in retail and offshore venues but faces headwinds among regulated entities.
2. Explosive Growth in Real-World Use Cases and Payments Velocity
USDC is winning where money actually moves the economy. Corporate and fintech players are replacing slow, expensive bank wires with near-instant, low-cost USDC settlements.
February’s record transfers highlight higher velocity: despite trailing in total supply, USDC processes significantly more genuine economic activity across payments, cross-border remittances, payroll, real estate, and tokenized asset transfers.
Data shows stablecoin B2B and payment volumes surging dramatically, with USDC capturing the majority of adjusted flows in sectors demanding clean liquidity. On high-performance networks like Solana and Ethereum Layer-2s, USDC’s speed and cost advantages amplify this edge.
In contrast, a large portion of USDT activity remains tied to retail trading, derivatives, and internal cycling.
3. Strong Supply Growth and Fresh Minting Momentum
USDC supply climbed to a 2026 high of about $79.6 billion on March 18, 2026 (DefiLlama), in line with Allium's count of Circle's reserve balance peaking at $79.2 billion on March 17 (Allium).
Arkham data showed more than $3 billion of USDC minted in the first week of March alone, with large issuances on Solana (Cointelegraph).
At the time, USDT supply was flat at about $184 billion (Cointelegraph), so the volume lead came from turnover, not size. For the size gap in more detail, see USDT is 2.5x bigger than USDC and moves 3x less.

4. Enterprise and Fintech Partnerships Favoring Transparency
Major players including Visa, Stripe, PayPal (via PYUSD expansion), BlackRock, and others have deepened integrations with USDC for settlements and treasury operations.
Circle’s focus on regulated partnerships and global payment rails has translated into higher real turnover.
Mizuho analysts cited the volume shift when raising Circle's (CRCL) 12-month price target to $120 from $100 (Bitcoin.com).
5. Perception and Compliance Edge in a Bifurcating Market
Both issuers support blacklisting for sanctions compliance, but USDC benefits from more frequent, detailed public reporting and a perception of tighter alignment with U.S. standards.
The GENIUS Act’s emphasis on federal oversight and attestations is widening this gap, rewarding the issuer seen as lower-risk for regulated counterparties.
USDT continues to dominate global retail liquidity and emerging-market remittances, but the “adjusted” metric highlights where institutional and economic activity is concentrating.
What’s Expected Next: The 2026 Outlook for USDC vs USDT
The rivalry is entering a new phase defined by velocity, legitimacy, and regulatory alignment rather than raw supply alone.
USDC’s Path:
Analysts expect the volume lead to hold or widen in coming quarters if institutional adoption and payments growth continue.
Sustained minting, deeper enterprise integrations, and full GENIUS Act implementation, now that the OCC rule is final, could push USDC toward greater parity in overall market share.
Watch for further supply gains and expanded use in RWAs, tokenized Treasuries, and cross-border corporate flows. A multi-chain strategy (Ethereum, Solana, and beyond) will likely amplify velocity.
Tether’s Response:
The January 27, 2026 launch of USAT (USA₮) represents Tether’s direct counterpunch.
Positioned for U.S. institutions and regulated flows, USAT starts small but carries Tether’s vast global network and liquidity advantages. Early listings on major exchanges signal scaling ambitions.
Tether’s strategy appears bifurcated: legacy USDT for retail, emerging markets, and high-liquidity trading; USAT for compliant U.S. and institutional use. Success will depend on how quickly USAT captures share from USDC in regulated corridors.
Broader Market Dynamics:
Supply growth has stalled rather than accelerated. Allium counts total stablecoin supply at $305 billion at the end of September 2026, only 0.4% above the start of the year (Allium Q3 2026). Expect continued divergence between the two coins depending on which metric you use.
A potential equilibrium may emerge, with multiple compliant issuers coexisting. Regulatory milestones (OCC final rules, parallel regimes in Europe via MiCA, and Asia) will shape competitive intensity.
Key Risks and Variables:
Faster-than-expected USAT adoption, shifts in reserve requirements, macroeconomic factors affecting Treasury demand, or changes in enforcement could alter trajectories. Geopolitical tensions may further boost stablecoins as a USD proxy.
The data confirms a structural shift is underway. Institutions are voting with real flows.
The dollar’s digital future is being decided in trillions of on-chain dollars and 2026 will reveal whether USDC’s momentum becomes lasting dominance or sparks a new era of intense, regulated competition.
Update, October 2026: Did the USDC Lead Hold?
Not on most measures. Allium's Q3 2026 report found that USDT carried 84% of stablecoin payment value from January to September 2026, with Tron settling two-thirds of it (Allium, October 15, 2026). For September alone, Visa Onchain Analytics data showed USDT at $182 billion of transfer volume (84% share) and USDC at $32.6 billion (15%) (AMBCrypto, citing Visa).
Supply moved the same way. USDC fell from its March high to about $71.3 billion on October 27, 2026, while USDT held about $182.1 billion (DefiLlama). Allium notes that Circle's revenue tracks that supply, because reserve interest is 94% of it (Allium).
The February flip still happened, but it was a raw transfer and adjusted-volume story driven by exchange and institutional flows. Allium screens out exchange, DeFi, infrastructure, automated and mint and burn flows, leaving just 2.5% of $97.9 trillion in raw 2026 transfers as end-user volume (Allium Q3 2026). On that end-user basis, USDT leads. Our USDT vs USDC guide explains why the two coins serve different users.
USDC vs USDT Volume: Dated Data Points, 2026
| Period | Metric (source) | USDC | USDT |
|---|---|---|---|
| February 2026 | Raw transfer volume (Allium via Cointelegraph) | $1.26T (about 70%) | $514B |
| Jan 1 to Mar 13, 2026 | Adjusted volume (Mizuho via Bitcoin.com) | $2.2T (about 64%) | $1.3T |
| September 2026 | Transfer volume (Visa Onchain Analytics via AMBCrypto) | $32.6B (15%) | $182B (84%) |
| Jan to Sep 2026 | Share of stablecoin payment value (Allium Q3) | n/a | 84% |
| October 27, 2026 | Supply (DefiLlama) | $71.3B | $182.1B |
| Sources | Cointelegraph, Bitcoin.com, AMBCrypto, Allium, DefiLlama |
The metrics are not interchangeable: raw transfer volume counts every on-chain move, adjusted volume strips some noise, and payment value keeps only end-user payments. USDC wins the first two in early 2026; USDT wins the last.
FAQ
Did USDC overtake USDT in volume in 2026?
Yes, on some measures and for part of the year. USDC led February 2026 raw transfer volume with about 70% and led Mizuho's adjusted volume count through mid-March, but USDT led stablecoin payment value from January to September.
Why did USDC volume rise so fast in early 2026?
Exchange and institutional flows, heavy minting in March and growing use on Solana and Ethereum layer 2s pushed USDC turnover far above its share of supply.
Which stablecoin is bigger, USDT or USDC?
USDT. On October 27, 2026 USDT supply was about $182.1 billion against about $71.3 billion for USDC, according to DefiLlama.
Why do volume figures for USDC and USDT disagree?
Raw transfer volume, adjusted volume and payment value filter different flows. Raw totals include exchange, DeFi and automated transfers, while payment value keeps only end-user payments, where USDT dominates.
