Circle’s Q3 2026 Earnings: Can Stablecoin Issuers Make Money Moving Dollars?
World's second largest stablecoin firm, Circle, dropped Q3 2026 earnings this week.
It grew stablecoin circulation to $73.3 billion, up 8% YoY, but reserve income fell 8%. Yet total revenue increased 17%.
Are stablecoin issuers discovering a new business model?
It has two very different sources of income.
1.Reserve Income | $658M, down 8% YoY
Stablecoin issuers earn money on the reserves backing the stablecoin by investing them across different short term instruments. Reserve income remains the biggest contributor to topline, accounting for 76% of Circle's revenue, but its economics depend on two factors:
- Interest rates: Largely outside Circle's control. A 100bps reduction in reserve yield would reduce annualised gross reserve income by approximately $733M at current average circulation.
- USDC supply: Growth requires paying for distribution. Circle incurred $409M in distribution and transaction costs, including $331M under its agreements with Coinbase. Coinbase held 31% of USDC in circulation at the end of Q3 2026, up from 24% a year earlier. Circle retains approximately 38% of gross reserve income.
Circle renewed its five-year partnership with Binance, which invested $100M in Circle and receives monthly incentives linked to USDC balances.
Despite average USDC circulation increasing 8%, reserve income declined as yields fell from 4.15% to 3.54%.
2.Other Revenue | $207M, up 627% YoY
The standout was $182M from one-off Arc token sales, more than offsetting the decline in reserve income.
➡️ But this raises a bigger strategic question: can Circle diversify away from an interest-rate-sensitive reserve model towards recurring ecosystem monetisation? Two developments are worth watching.
Tazapay | Monetising Global Payments
Circle Payments Network reached $41B in annualised payment volume, growing 15.2x YoY.
Its planned acquisition of Tazapay adds local banking and payout connectivity across 100+ markets, connecting USDC settlement with real-world fiat payments. This gives Circle a potential route to monetising payment flows beyond the interest income earned on circulating USDC.
Arc | Monetising Programmable Settlement
Arc newly launched blockchain processed over $30B in USDC transaction volume since launch. Beyond blockchain settlement, Circle is developing an agentic commerce stack enabling AI agents to discover services, execute payments and settle autonomously using USDC. These capabilities create opportunities for recurring network and service revenue, although the economics remain unproven.
The Bigger Picture
Circle pays to attract and retain USDC balances, while monetary policy largely determines what it earns on those reserves. Other revenue reached 24% of the quarterly total, but excluding the one-off Arc token sale, it accounted for just 3%.
The test for Tazapay and Arc is whether they can turn growing payment and settlement volumes into recurring fees large enough to cushion a fall in reserve income.
If Circle wants to earn more from moving dollars, who will capture the revenue from each payment, and who will bear the cost of delivering fiat around the clock?
