Fintech news: Circle's Q2 2026 shows USDC at $73.3 billion

There is a particular kind of company that sits where fintech meets monetary policy: one whose revenue depends less on how many people use its product than on what interest rates are doing to the money held behind it. Circle Internet Group, the issuer of the USDC stablecoin, is that kind of company. Its second-quarter 2026 results, released on August 5, 2026 and furnished to the SEC, were among the more revealing pieces of fintech news of the summer because they showed both forces at work at once.

The headline figures

USDC in circulation stood at $73.3 billion at the end of the quarter, up 19% from a year earlier. Average USDC in circulation during the quarter was $76.5 billion, up 25%. Total revenue and reserve income came to $701 million, a 7% increase. Net income from continuing operations was $48 million, which the release described as an improvement of $530 million from the prior-year quarter. Adjusted EBITDA rose 8% to $143 million.

The reserve return rate, the yield Circle earns on the assets backing USDC, was 3.5%, down 66 basis points from a year earlier.

Usage grew faster than revenue

The gap between those numbers tells the main story. Average circulation grew 25%, but revenue and reserve income grew only 7%. The difference is largely explained by the lower reserve return rate. Circle is holding more money on behalf of USDC holders, but earning less on each dollar.

Activity on the network grew much faster still. The release put USDC onchain transaction volume at $14.8 trillion for the quarter, up 151% from a year earlier. That figure measures how much USDC moved, not how much Circle earned, and the contrast with revenue growth highlights how loosely usage and income are connected in the stablecoin business model.

For a stablecoin issuer, adoption and revenue can move in different directions, and the interest-rate cycle decides which one wins.

The payments network

The more forward-looking numbers came from the Circle Payments Network, the company’s effort to build a payments business on top of USDC. The release reported annualized transaction volume of $14.7 billion on the network, up 76% from the prior quarter, and 175 enrolled financial institutions, up 29% from the prior quarter.

Those figures are small relative to USDC’s onchain volume, but they describe a different kind of activity: institutions using stablecoins to move money for payments rather than for trading. For a company whose income is closely tied to interest rates, a payments business with its own fee economics would be a way to diversify.

The release also discussed Arc, a blockchain platform Circle is developing, citing more than 100 ecosystem builders and a scheduled public mainnet launch date of September 16, 2026.

Guidance

For full-year 2026, Circle guided to other revenue of $310 million to $330 million, an RLDC margin of 41.7% to 43.7%, and adjusted operating expenses of $570 million to $585 million. The other revenue line is the one to watch for evidence that non-interest income is becoming a larger share of the business.

Why this fintech news matters

For fintech companies and banks building on stablecoins, Circle’s results provide a read on demand for regulated dollar tokens. Growth in circulation and in enrolled institutions suggests rising institutional use. For policymakers working through GENIUS Act rulemakings, the numbers illustrate the scale of activity the new rules will govern.

For investors and analysts, the quarter underscored the sensitivity of stablecoin economics to rates. A falling reserve return rate can offset strong growth in balances, which is why diversification efforts such as the payments network and other revenue sources matter to the company’s model.

What to watch

Subsequent quarters will show whether Circle Payments Network volume continues to grow at a high rate, whether other revenue tracks the guided range, and how the reserve return rate moves with interest rates. The Arc mainnet launch date fell after the quarter, and the company’s later disclosures will indicate how that platform develops.
