Quarterly Altcoin Spotlight: Circle Bets Its Future on Payments Infrastructure Beyond USDC

Circle is no longer just a stablecoin issuer — it is building the payments infrastructure layer that could redefine how dollars move on the internet. The company generated $2.75 billion in revenue during 2025, representing 64 percent year-over-year growth with a three-year compound annual growth rate of 53 percent. But the overwhelming majority of that revenue — 95.2 percent in Q2 2026 — comes from interest earned on USDC reserves, not from transaction fees or software subscriptions. That concentration is the central tension in the investment case: Circle has one of the strongest distribution positions in all of crypto, but its business model remains tethered to the interest rate cycle rather than to the payment volumes flowing through its rails.
