Circle Internet Group, Inc. rode a wave of accelerating stablecoin use this week, publishing fourth-quarter and full-year 2025 results that underline how quickly dollar-denominated digital cash is being woven into real-world finance. In a short, bullish message on X, the company said “momentum is building in internet-native finance,” pointing to a trio of eye-catching metrics: $75.3 billion in USDC in circulation, $11.9 trillion in onchain USDC transaction volume for the quarter, and $770 million in total revenue and reserve income that together paint a picture of fast adoption.
Those headline figures come from Circle’s formal earnings release, which shows a 72% year-over-year increase in USDC in circulation and an astonishing 247% jump in onchain transaction volume for Q4’25 versus Q4’24. Reserve income, the bulk of Circle’s revenue that comes from investing the assets backing USDC, rose sharply, helping the company report $770 million in total revenue and reserve income for the quarter, up 77% from a year earlier. Adjusted EBITDA surged as well, reflecting strong operating leverage in the business.
Circle’s management framed these gains as more than just accounting wins. CEO Jeremy Allaire described the quarter as another step toward building what the company calls an “Economic OS for the internet,” infrastructure that, the company says, will power everything from faster cross-border payments to new possibilities around agentic AI.
From Testnet to Mainnet
The release also highlighted several product and commercial milestones that show that vision: Arc, Circle’s public testnet, has drawn more than 100 participants and is showing near-100% uptime and sub-second finality; the Circle Payments Network has enrolled dozens of financial institutions and is generating billions in annualized transaction volume; and the firm is seeing growth across other digital assets it supports, like EURC and a relaunched USYC.
Partnerships and institutional adoption have been key themes. The earnings package lists recent commercial wins and collaborations that map Circle’s reach into traditional finance and fintech: Visa Inc. announced that U.S. issuers and acquirers can now settle with USDC, enabling settlement outside normal banking hours; Intuit struck a multi-year deal to integrate USDC payments and infrastructure across its products; and Circle said it is working with Polymarket to make USDC the settlement asset for prediction markets.
On the public-sector front, the company noted that the Government of Bermuda plans steps toward becoming the first fully onchain national economy using Circle’s infrastructure. The release also pointed to a regulatory milestone: in December, Circle received conditional approval from the Office of the Comptroller of the Currency to establish a national trust charter, a move the company says strengthens the legal scaffolding around USDC and its broader platform.
That regulatory progress, alongside growing enterprise deals, may be helping explain why investors reacted positively to the results. Circle’s stock jumped in early trading after the report, as analysts and traders digested the combination of top-line growth and operational momentum. But the picture is complex. While the company’s operating metrics and adjusted profits showed strong expansion, Circle reported a net loss for the full fiscal year, largely tied to a one-time, IPO-related stock-based compensation charge.
Management provided forward-looking guidance as well, flagging a multi-year 40% compound annual growth target for USDC in circulation and specific ranges for other revenue and margin metrics in fiscal 2026. Investors and industry watchers will now be watching whether the Arc mainnet launch and continued integration with banks and platforms can sustain the breakneck growth the quarter captured.
