How Does Circle Make Money? USDC Revenue Structure & Coinbase Distribution Deal [2026 Update]
W Insights · Series Part 2 · The Battle for Digital Dollar Dominance in the AI Era (5-part series)
USDC revenue structure is anchored by one striking fact — 96% of Circle’s revenue comes from US Treasury interest. We dissect the S-1 filing to reveal how Coinbase walks away with 54% of USDC revenue through the distribution agreement.
In Part 1, we saw that the stablecoin market has grown to roughly $317B. Now the question is: how exactly does Circle, the issuer behind USDC and 25% of that market, make money?
“They earn fees from issuing USDC, right?” — that’s only half the picture. Circle’s business model is unusually clean. In one line: “a company that uses USDC issuance as a pretext to invest in US Treasuries and pocket the interest.” And more than half of that interest flows to Coinbase. This is the heart of the USDC revenue structure.
1. The Striking Fact: 96% of Circle’s Revenue Is US Treasury Interest — The Core of USDC Revenue Structure
Circle’s FY2025 total revenue: $2.747B (~$3.85B KRW equivalent). Break it down and the structure becomes obvious:
- Reserve Income: $2.637B (96%)
- Other Revenue: $110M (4%)
So 96% of Circle’s revenue is not from USDC issuance fees — it comes from investing the dollars received during USDC issuance into US short-term Treasuries (T-bills) and collecting the interest. Let’s unpack what that actually means.
Circle’s Actual Business Mechanism
When a company deposits $100M and receives 100M USDC, Circle does not hold the $100M in a sock drawer. It places over 90% into US short-term Treasuries (T-bills) and overnight repurchase agreements (repos), both managed by BlackRock and BNY Mellon. These yield roughly 4% per year — so on $100M alone, Circle clears about $4M annually in interest.
USDC holders receive nothing. They just swap $1 for 1 USDC. That spread — the gap between “digital dollar paying no interest to users” and “Circle’s interest-bearing reserves” — is Circle’s profit. Same structure as a bank, really: banks pay depositors almost nothing and earn interest by lending or holding bonds.
2. Why Coinbase Takes Half of USDC Revenue
Here’s the second uncomfortable fact about USDC revenue structure. Circle’s enormous interest income — roughly 54% flows automatically to Coinbase. In FY2025, around $1.30B (~$1.8 trillion KRW) was distributed to Coinbase. How did this structure get built?
The Fateful Partnership Born in 2018
USDC launched in 2018 through Centre Consortium, a joint venture between Circle and Coinbase. In August 2023, the consortium dissolved, but in its place came the Distribution Agreement. The asymmetry of that agreement now shapes everything.
The two key clauses:
- USDC held on the Coinbase platform → 100% of the resulting interest income goes to Coinbase.
- USDC circulating elsewhere (Binance, Bybit, ordinary wallets) → reserve interest is split 50/50.
On first read it sounds like a one-sided deal. But Circle’s leadership had no real choice. For USDC to grow, it needed distribution rails, and Coinbase was the largest regulated exchange in the US — most retail and institutional USDC custody flows through Coinbase wallets. Without that distribution deal, USDC would have struggled to dent USDT’s market share and reach today’s scale. The USDC revenue structure is essentially renting Coinbase’s distribution and paying a heavy share back to the landlord.
Why It Still Isn’t a Losing Deal for Circle
From Circle’s perspective, this is not pure loss. Coinbase is distributing USDC globally on Circle’s behalf without Circle paying for the channel. Think franchise economics: running 100 corporate stores requires staggering capex, but signing 100 franchisees and taking a revenue share keeps headquarters lean.
Same for Circle. By giving away half of revenue, Circle secures global USDC distribution without paying for infrastructure, marketing, or compliance personnel one branch at a time. That’s why operating margins stay strong. The Q4 EBITDA margin hitting 54% is a direct consequence of this structure.
3. Coinbase’s USDC Share Has 4×’d in 4 Years
The asymmetry of the contract has gotten worse over time. The share of USDC held on Coinbase platform has surged from ~5% to 22% in four years. What this means:
- 2022: Coinbase USDC share 5% → distribution $248M
- 2023: 12% → $691M
- 2024: 20% → $908M
- 2025: 22% → ~$1,300M
As more USDC parks on Coinbase, 100% of the interest on that pile flows to Coinbase. And Coinbase has been actively accelerating the trend by paying users a “USDC Rewards” yield (around 4% APY) to keep USDC on platform — handing a slice of interest back to depositors while pulling more USDC into custody.
Korean investors evaluating Circle must internalize this point. The more USDC succeeds, the more Coinbase revenue grows. Some analysts treat Coinbase stock (COIN) as an alternative play on USDC growth. In 2024, Coinbase’s USDC-related revenue alone hit $908M — about 13.8% of Coinbase’s total revenue. Read about it directly on SEC EDGAR’s Circle S-1 filing.
4. Is Circle Really Just a “Short-Term Treasury ETF in Disguise”? Structural Risk
Now we get to the biggest risk in the USDC revenue structure. If 96% of revenue is US Treasury interest, then in plain terms Circle’s revenue line is tied to the Federal Reserve’s policy rate.
Why does this matter now? Because by 2026 the market is pricing in Fed rate cuts in the second half of the year. A 0.5% cut already implies roughly $220M of revenue pressure for Circle. This is the single most important variable in Part 5 (Investment Conclusion).
That’s why some analysts label Circle “a short-term Treasury ETF wrapped in USDC packaging.” A company’s fundamentals being more sensitive to an external macro variable (the Fed funds rate) than to its product or service competitiveness raises a fair question: can a business like that ever justify a P/E multiple of 100×, the way a true SaaS platform might?
5. Three Moves Circle Is Making to Reduce Dependence
Circle’s leadership knows this structural risk. The diversification push is already in motion along three lines:
① Arc Blockchain — Layer-1 Infrastructure
A Layer-1 blockchain Circle built in-house. The testnet launched in October 2025 with 100+ participating institutions including Goldman Sachs, Deutsche Bank, Visa, and Mastercard. The mainnet is expected in 2026, and any transaction fees generated there become a new revenue stream — not tied to Fed rates.
② Circle Payments Network (CPN)
A stablecoin-based payments network. As of February 2026, 55 financial institutions have joined and annualized transaction volume reached $5.7B. Korean integrations like Hana Bank have joined the network. CPN transaction fees feed Circle’s new revenue lines.
③ EURC, USYC and New Product Lines
Euro-pegged EURC (€389M circulating, 3.8× year-over-year growth) and US Treasury tokenized USYC ($1.7B). USYC in particular is Circle’s pre-emptive bet on the RWA (Real World Asset tokenization) market.
Combined “Other Revenue” surged from $15M in FY2024 to $110M in FY2025 — +633%. Still only 4% of total revenue, but this is where Circle’s 5-year future is being built. Part 4 will dig into each of these in detail.
6. Frequently Asked Questions (Q&A) — USDC Revenue Structure
Q1. Do USDC holders earn interest?
Not directly. Circle’s business model is precisely not paying USDC holders interest and keeping the spread. Some exchanges like Coinbase do pay users a “USDC Rewards” yield to attract custody, but that comes from the exchange’s own pocket.
Q2. Does the Coinbase distribution deal make Circle stock unattractive?
Not necessarily. Even after the distribution payment, FY2025 Revenue-Less-Distribution-Costs (RLDC) was $1.083B — up 42% year-over-year, with strong operating margins. But anyone valuing Circle must explicitly model the Coinbase share rather than looking at gross revenue.
Q3. If rates fall, is Circle stock automatically a sell?
Short term, possibly. Long term, growth in USDC circulating supply can offset rate pressure. For example, a 1% rate cut paired with 30% growth in USDC circulation roughly keeps revenue flat. So Circle investors need to watch both the Fed path and USDC circulation growth.
Q4. Is Coinbase stock a better play on USDC than Circle?
If you’re looking for pure USDC exposure, the answer leans toward Coinbase — USDC revenue is only 13.8% of Coinbase’s revenue, so there’s diversification. But Coinbase carries exchange-volume volatility as its own risk. Holding both is essentially a diversified bet on the USDC ecosystem.
“We are heavily dependent on a small number of distribution partners. A material change in any single partner’s economics or relationship could materially impact our revenue and earnings.”
Circle Internet Financial S-1, Risk Factors
Behind the “stablecoin issuer” label, the USDC revenue structure is essentially “a short-term Treasury fund plus a Coinbase distribution lien.” When rates stay elevated and Coinbase keeps cooperating, the model is powerful. But it can fall apart if either of those legs weakens. In Part 3, we will dive into Circle’s FY2025 financials line-by-line: quarterly revenue trend, cost structure, the 412% surge in EBITDA — and the $70M one-off loss from IPO expenses.
