Circle processed $32 trillion in USDC transfers, yet 95% of its revenue relies entirely on interest rates
Adjusted USDC switch quantity reached $32 trillion in 2026 by Coin Metrics’ August measurement, with every greenback of provide turning over 741 instances at an annualized charge. Those figures sign attain and settlement depth. Circle’s second-quarter revenue, nevertheless, remained dominated by yield on the property backing USDC.
For the three months ended June 30, reserve earnings provided $667.7 million of Circle’s $701.3 million in whole revenue and reserve earnings, or 95.2%. Transaction revenue was $5.3 million. Volume is a utilization sign; balances and yields nonetheless decide most of Circle’s revenue base.
Arc, Circle’s blockchain infrastructure scheduled for a Sept. 16 public mainnet launch, is the corporate’s clearest try and construct a direct charge floor round some of that exercise. Its take a look at is whether or not visitors can develop into retained recurring revenue.
How USDC switch quantity is generated
Coin Metrics described the $32 trillion as adjusted USDC transfer volume in 2026 through its August analysis, not shopper funds, distinctive financial settlement or a full-year whole. Its annualized velocity estimate measures how usually provide strikes relative to its dimension.
The composition of that motion issues. Coin Metrics’ bottom-up evaluation examined uncooked switch quantity by tagged lending contracts, decentralized exchange pools and recognized change wallets. On Base, 69% of USDC volume concerned DEX liquidity provision and 23% concerned flash loans. On Ethereum, flash loans accounted for 65%.
Those classes symbolize actual crypto-market demand. Liquidity rebalancing, collateral motion and arbitrage make markets operate, whereas producing monumental gross transfers with out a matching improve in internet capital moved, purchases made or charges collected by Circle. A liquidity place that’s repeatedly rebalanced could transfer the identical {dollars} many instances, whereas a flash mortgage is borrowed and repaid inside one transaction.
Coin Metrics additionally handled its tagged shares as lower-bound estimates. About 8% of Base quantity and 33% of Ethereum quantity remained outdoors the recognized classes, and that residual might embody funds, bridging, treasury exercise and different settlement. It can’t safely be relabeled as business funds.
The result’s a greater studying of USDC’s velocity: the stablecoin is deeply embedded in crypto’s monetary plumbing, however headline switch quantity just isn’t a revenue ledger.
Circle’s personal Q2 exercise metric reinforces the hole. The firm stated USDC onchain transaction volume rose 151% year over year to $14.8 trillion, whereas period-end circulation elevated 19% to $73.3 billion. Total revenue and reserve earnings rose 6.6% to $701.3 million.
The Coin Metrics and Circle quantity measures are usually not interchangeable. Coin Metrics experiences adjusted switch quantity; Circle’s submitting defines its determine as native and canonically bridged USDC processed throughout supported chains apart from Solana. Both present scale, however neither implies that Circle fees a toll on each switch.
| Signal | Reported end result | What it exhibits |
|---|---|---|
| 2026 adjusted USDC switch quantity | $32 trillion by Coin Metrics’ August measurement | Onchain motion, not shopper funds |
| Annualized adjusted-supply velocity | 741x | How continuously provide turns over |
| Circle Q2 USDC onchain quantity | $14.8 trillion, up 151% | Company-defined community exercise |
| Q2 reserve earnings | $667.7 million, 95.2% of whole | Interest and dividends on reserve property |
| Q2 transaction revenue | $5.3 million | Usage-, volume- or event-driven revenue |
| Q2 distribution, transaction and different prices | $412.5 million | Costs that sit between gross revenue and working leverage |
The SEC filing exhibits the place Circle’s development translated into revenue. The firm attributed about $147.4 million of year-over-year reserve-income enchancment to a 25.2% improve in common each day USDC circulation. A 66-basis-point decline in common yields offset about $113.9 million of that acquire, leaving reserve earnings up roughly $33.5 million.
That bridge explains why circulation issues extra to present revenue than velocity. More USDC excellent expands the reserve base that earns interest. The identical USDC transferring lots of of instances doesn’t robotically create lots of of revenue occasions for Circle.
The submitting additionally separates reserve earnings from retained economics. Circle recorded $410.4 million of distribution and transaction prices in the quarter, together with $324.6 million of Coinbase-related distribution prices, and $412.5 million when different prices have been included. The Coin Metrics switch whole doesn’t straight drive these prices. Their scale nonetheless exhibits why gross reserve earnings can’t be learn as working margin.
Rates stay the bigger near-term sensitivity. Holding circulation and reserve allocation fixed, Circle modeled a 100-basis-point transfer from June’s common yield as altering reserve earnings by about $737 million and distribution and transaction prices by about $360 million over the next 12 months. That was a hypothetical sensitivity, not steerage, however its scale exhibits how far Circle stays from a revenue combine pushed primarily by transaction charges.
Arc’s monetization take a look at
Arc is Circle’s clearest try and carry extra financial exercise onto infrastructure it helps function. Circle’s newest Aug. 5 statements positioned Arc in non-public mainnet with greater than 100 builders and scheduled public mainnet for Sept. 16. As of these statements, the general public launch had not occurred.
Arc’s design offers the experiment a direct connection to USDC utilization. Its gas and fee system denominates transaction charges in USDC, making a dollar-denominated cost every time the community processes exercise. That is a extra seen charge floor than abnormal USDC transfers throughout third-party chains.
Recurring Circle revenue from Arc stays unproven. Arc’s documentation doesn’t set up how a lot gas-fee revenue Circle will retain, and Circle’s Aug. 5 record of builders and potential integrations doesn’t show transaction quantity, business demand or margin after the scheduled public launch. The necessary post-launch sign shall be whether or not exercise seems in Circle’s transaction and repair revenue relatively than solely in community statistics.
The ARC Token presale is a separate financial occasion. Circle agreed to promote 807.5 million tokens for about $242.2 million, however the Q2 filing recorded the proceeds as deferred revenue, not acknowledged quarterly revenue. The potential token is tied to a doable later transition from proof of authority to proof of stake or delegated proof of stake, whose timing and phrases stay conditional.
Treating the presale as proof that Arc has already diversified Circle’s working revenue would due to this fact confuse financing and future efficiency obligations with recurring community economics.
Arc doesn’t have to displace reserve earnings instantly to matter. It wants to indicate that Circle can seize a repeatable share of exercise that USDC already permits elsewhere.
That creates a concrete scorecard after Sept. 16: whether or not public mainnet launches as scheduled, what sorts of transactions dominate, whether or not functions generate sustained exercise outdoors mechanical liquidity loops, and whether or not Circle begins reporting materials development in transaction or subscription and repair revenue. Retained economics will matter as a lot as gross charges.
USDC’s $32 trillion year-to-date switch whole demonstrates attain and liquidity. Coin Metrics’ decomposition exhibits why that quantity shouldn’t be mistaken for funds revenue. Until Arc or one other Circle product turns extra of that motion into sturdy charges, Circle’s enterprise will proceed to be ruled primarily by what number of USDC are excellent, what their reserves yield and the way a lot of that earnings stays after distribution prices.
