Hook
The 2025 10-K filing by Circle was meant to showcase a triumphant year: USDC supply surged 72%, reaching $753 billion in circulation. Yet buried in the fine print was a figure that should chill every stakeholder: $1.4 billion in distribution costs — a staggering 51% of total revenue. The number tells a story not of thriving adoption, but of a company that must pay ever-increasing tolls to keep its stablecoin in the hands of users. And when you follow the money, you realize the real beneficiaries are not Circle’s shareholders, but its distribution partners and a new breed of protocols that have learned how to extract value from the reserve income.
Context
USDC has long been positioned as the compliant, transparent rival to Tether’s opaque dominance. Circle’s partnership with Coinbase, formalized in August 2023 with a three-year agreement, was supposed to be the engine for growth. Coinbase, the largest US exchange, became the primary on-ramp and off-ramp for USDC, earning a significant split of the reserve yield in return. The model worked while interest rates stayed high — Circle earned over $2.7 billion in reserve income in 2025, and the distribution costs seemed a price worth paying for dominance. But cracks are forming. New competitors — Open USD, a consortium backed by Visa and Mastercard, and Hyperliquid, a decentralized derivatives platform — have started to offer alternative economic structures that challenge the very foundation of USDC’s business model. The 2026 August agreement renewal with Coinbase is now a looming liability rather than a pillar of strength.
Core
Let’s dissect the $1.4 billion. Circle’s revenue grew 64% from 2024 to 2025, but distribution costs rose by nearly 50%. This means the marginal revenue from each new USDC dollar is being increasingly consumed by the cost of acquiring and retaining that dollar. The 39% net margin, flat year-over-year, masks a deteriorating cost structure. Why? Because the growth itself is being subsidized by an ever-larger payout to Coinbase. If you look at the flow: every time a user mints USDC, Circle takes the fiat deposit, invests it in Treasuries, and shares the yield with Coinbase. In 2025, the share was roughly 51 cents per dollar of revenue. That’s not a partnership; that’s a tax.
Now consider the threat from Hyperliquid. The exchange’s August 2025 AQAv2 framework allowed it to redirect approximately 90% of the reserve income generated by USDC held on its platform to itself. By using its native token (HYPE) and leveraging yield-bearing assets, Hyperliquid effectively turned USDC into a zero-yield asset for the user while extracting almost all the economic value. Auditing the narrative, not just the numbers. This is not a technical hack — it’s an economic one. Hyperliquid maintains USDC liquidity (because users still need the stablecoin to trade), but the profit flows to the protocol, not to Circle. The $1.4 billion distribution cost is already inflated; if other major protocols (dYdX, Uniswap, even Binance) replicate this model, Circle’s reserve income could be squeezed even further, potentially halving its effective revenue from USDC held on-chain.
Then there’s Open USD. Announced in early 2025, this consortium — comprising over 140 entities including Visa, Mastercard, and a handful of banks — offers a fundamentally different value proposition: share the reserve yield with all participants after deducting management fees. For Coinbase, which already earns a cut of USDC revenue, Open USD represents an alternative where it could keep an even larger share of the yield, since it would not have to split with Circle. The pressure point table from the original analysis makes this clear: Coinbase controls concentrated distribution, Open USD offers an alternative cooperative model, and Hyperliquid’s AQAv2 extracts ~90% of economic income. The 2026 August re-set is the lightning rod.
The metrics that matter most: the marginal value of each new USDC dollar is declining. In 2025, to grow supply by $315 billion (from $438B to $753B), Circle had to increase distribution costs by $4.8 billion. This implies an incremental cost of about 1.5% of the new supply — but that marginal cost is rising as the low-hanging fruit (retail users via Coinbase) are already captured. The next wave of growth requires deeper penetration into DeFi, where protocols like Hyperliquid will demand their own cuts. Where code meets chaos, truth emerges. The real question: can Circle sustain a model where it keeps only 39% of the revenue it generates, with that percentage poised to shrink?
Contrarian Angle: The Hidden Strength?
However, not all signs point to doom. Circle’s regulatory moat — the recent OCC approval to establish a national trust bank — is a genuine barrier. Open USD, while promising, lacks the same level of regulatory clarity and audited reserves. Hyperliquid’s model, while clever, is not easily replicable: it requires a strong native token to incentivize liquidity and complex smart contracts to route yield. Most protocols lack the governance structure and user base to pull this off. Moreover, the majority of USDC supply still sits on centralized exchanges like Coinbase, where AQAv2-style extraction is not possible. Circle’s treasury and custody partnerships with BlackRock and BNY Mellon provide institutional trust that neither Open USD nor Hyperliquid can match—yet.
But the contrarian view must also acknowledge the timeline. If the Fed cuts rates significantly in 2026 — a scenario many economists foresee — Circle’s reserve income will shrink, while the distribution costs (tied to supply, not yield) may not fall as fast. The margin would compress dramatically. If the Coinbase agreement is renewed on even slightly less favorable terms (e.g., Circle pays 55% instead of 51%), the net margin could drop to 30% or below. And if rates remain low, the entire revenue base collapses. The supposed strength of regulatory compliance becomes a cost center, not a profit center.
Takeaway
USDC’s 2025 growth was a mirage — a $1.4 billion illusion of strength. The real story is a company paying increasingly high tolls for distribution, while its partners and competitors design mechanisms to extract the value Circle creates. The August 2026 Coinbase re-set is the moment of truth. If Circle cannot reduce its distribution cost — either by renegotiating with Coinbase or by bypassing it — then every new USDC dollar will bring diminishing returns. The architecture of trust, rebuilt line by line, now depends on whether Circle can reclaim its margins before the next Fed move or the next protocol copycat strikes. Watch the yield correlations, monitor the governance proposals on Hyperliquid, and most importantly, follow the discussions between Circle and Coinbase. Because in this game, the toll collector wins — and right now, Circle is not the collector. It’s the one paying.
