Circle’s USDC business has two connected parts: reserve income and distribution sharing. Assets backing USDC generate income for Circle, while agreements with Coinbase and other approved partners direct part of that income toward platforms that help circulate and support the stablecoin. The amount Circle keeps therefore changes with USDC in circulation, reserve yields, platform balances and partner incentives.
Circle’s core USDC business model
USDC is designed to be backed by reserve assets. Those assets produce income, which Circle reports as reserve income. Reserve income was 95% to 99% of Circle’s total revenue in each of 2022, 2023 and 2024, according to Circle’s 2025 SEC filing. That makes the economics closer to an asset-yield and distribution business than to a conventional software subscription model.
The engine has two variables:
- How much USDC is outstanding. More tokens in circulation generally mean a larger reserve base capable of generating income.
- What the reserves earn. Changes in market yields can raise or reduce income even when circulation is unchanged.
Circle does not keep every dollar of reserve income. It pays distribution costs to Coinbase and may pay negotiated amounts to other approved participants. A useful conceptual formula is:

The payment base is then divided under contractual rules. Circle retains an issuer portion, platform-related allocations are made, approved ecosystem participants may receive negotiated payments, and Coinbase receives 50% of the residual payment base after those deductions. The exact amounts can change from day to day as balances, yields, expenses and contracts change.
What drove Circle’s 2024 reserve-income increase?
Circle reported that reserve income increased by $230.5 million, or 16.1%, in 2024 compared with 2023. The company attributed the increase to both circulation and yield rather than to one factor alone.
| 2024 change driver | Circle’s attribution | Underlying change |
|---|---|---|
| Higher average USDC circulation | $139.9 million | Average daily circulation rose 9% |
| Higher average reserve yields | $89.9 million | Average yields increased by 25 basis points |
| Total reserve-income increase | $230.5 million | 16.1% year-over-year increase |
The two contributions are not interchangeable. Circulation growth can continue to support income even if rates fall, while a higher-yield environment can lift income without equivalent growth in USDC usage. Conversely, a decline in market yields can reduce reserve income even when the token supply expands.

How the payment waterfall works
Circle and Coinbase describe a waterfall rather than a single fixed commission. The starting point is daily reserve income after specified third-party reserve-management fees and expenses. The remaining payment base is allocated in stages.
| Stage | Recipient or basis | What it means |
|---|---|---|
| 1. Netting expenses | Payment base | Daily reserve income is reduced by specified third-party reserve-management fees and expenses. |
| 2. Issuer allocation | Circle | Circle retains a portion for issuing and administering USDC. |
| 3. Platform allocations | Circle and Coinbase | Allocations are tied to the amount of USDC held on the respective platforms. |
| 4. Negotiated participant amounts | Approved ecosystem partners | Contracts can direct portions of the remaining economics to other distributors or strategic participants. |
| 5. Residual split | Coinbase | Coinbase receives 50% of the residual payment base after the preceding deductions. |
“50%” does not mean Coinbase receives half of gross reserve income. The percentage applies to the residual after the issuer portion, platform allocations, negotiated payments and specified expenses. Because those deductions are not a single public universal amount, a reader cannot calculate Coinbase’s payout from USDC supply alone.
Circle records payments to Coinbase as distribution costs. Those costs are therefore an expense of building and maintaining USDC distribution, not a separate reserve asset or a reduction in the number of USDC tokens outstanding.

Why Coinbase receives a share
Circle’s 2025 annual filing says Coinbase supports USDC usage across key products, including on-ramps and off-ramps. In exchange, Circle makes payments tied principally to net reserve income from USDC. The arrangement gives Coinbase a financial reason to make USDC available, liquid and useful to its customers.
The contract also includes strategic elements beyond the daily revenue split. Circle’s filing says Coinbase received a minority equity stake in Circle and a perpetual license for certain stablecoin trademarks, subject to termination rights in specified circumstances. Those rights align the companies commercially, but they do not turn Coinbase’s payout into a fixed interest rate or guarantee a particular annual amount.
Platform balances matter because the agreement is sensitive to where USDC is held. Circle’s earlier disclosure states that the greater the proportion of USDC in circulation held on Coinbase’s platform, the greater the proportion of reserve income payable to Coinbase. If more USDC is held on Circle’s platform or elsewhere, Coinbase’s share is smaller under that balance-linked mechanism.
For December 31, 2023, Circle reported approximately 2% of USDC on Circle’s platform, 12% on Coinbase’s platform (based on Coinbase information) and 86% outside both platforms. These percentages describe that date and the stated measurement basis; they are not a permanent market-share forecast.
How much did Circle pay Coinbase?
| Year | Coinbase-related distribution costs recorded by Circle | Qualification |
|---|---|---|
| 2024 | $924.5 million | Reported in Circle’s 2025 Form 10-K; includes the contractual distribution-cost economics for that year. |
| 2025 | $1.4 billion | Reported in Circle’s 2025 Form 10-K; the higher figure reflects the year’s reserve-income, balance and incentive conditions. |
These are accounting figures for Coinbase-related distribution costs, not a claim that Coinbase received 50% of Circle’s total revenue. They also should not be read as a fixed annual fee: the payment base and contractual allocations vary with reserve income, platform balances and other deductions.
Circle said 2024 distribution costs increased alongside higher reserve income, greater Coinbase on-platform balances and new strategic distribution incentives. That combination illustrates an important trade-off: stronger USDC distribution can enlarge the income pool while also increasing the amount shared with the distributors that created that growth.

Do other exchanges, wallets and fintechs get paid?
Yes, Circle’s filings say approved participants may receive a portion of the residual payment base to encourage stablecoin circulation. The commercial terms are not necessarily uniform. A wallet, exchange, fintech or payment platform can have a negotiated contract with different eligibility rules, rates, minimums or incentive periods.
Circle’s 2024 disclosure identified a $60.25 million upfront, one-time Binance fee within other distribution incentives. That payment is distinct from recurring Coinbase-related distribution costs and should not be treated as a standard fee paid to every exchange or wallet.
Circle’s official 2026 company article provides additional current context: it reports approximately $1.4 billion of first-half revenue, approximately $819 million paid to USDC distribution partners and transaction costs, more than 150 partners with an economic interest in USDC growth, and a five-year Binance commercial agreement that includes a $100 million investment in Circle. These figures are Circle’s own company-reported claims and should be distinguished from audited SEC financial-statement figures. The first-half period and the article’s accounting presentation should be checked before comparing them directly with a full-year distribution-cost line.
The existence of a partner program does not mean every platform earns reserve income automatically. Payment depends on approval, contract language, qualifying balances or activity and the applicable payment-base formula.
Why Circle’s earnings are sensitive to interest rates and circulation
When USDC circulation grows
A larger average daily supply generally expands the reserve base. If yields and expenses are unchanged, that can increase reserve income. It can also increase partner payouts when contracts use platform balances or residual sharing, so Circle’s net benefit is less than the gross increase in reserve income.
When reserve yields rise
Higher average yields increase income on the existing reserve base. Circle attributed $89.9 million of its 2024 reserve-income increase to a 25-basis-point rise in average yields. This is the rate-sensitive side of the model and can reverse when market yields decline.

When reserve yields fall
A later Circle filing described declining average yields as an offset to circulation-driven growth. In that environment, USDC can continue gaining supply while reserve income grows more slowly—or falls—because each dollar of reserves earns less.

Distribution costs can increase faster than revenue if more USDC sits on partner platforms or if Circle commits new incentives. The result may be excellent adoption but weaker net economics for Circle in the short term.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to evaluate Circle’s USDC economics
Readers comparing stablecoin business models should separate the following questions rather than focus on a single headline revenue number:
- What assets generate the reserve yield? Asset type, maturity and liquidity affect both income and risk.
- How dependent is revenue on reserves? Circle’s 95%–99% share for 2022–2024 indicates very high dependence on reserve income during those years.
- How are distributors paid? Check whether payments are based on balances, transaction activity, a residual split, fixed incentives or negotiated terms.
- How transparent are reserves and partner costs? Look for audited filings, definitions of reserve income and separate disclosure of distribution expenses.
- How sensitive is the model to rates and supply? A model can benefit from either higher yields or greater circulation, but the two drivers have different durability and risks.
- Is there non-reserve revenue? Transaction, infrastructure or other service fees can diversify an issuer whose income otherwise depends heavily on reserves.
This framework also prevents a common mistake: comparing one issuer’s gross reserve income with another issuer’s revenue after partner payouts. The accounting bases must match before the comparison is meaningful.
What the model means for users and observers
For a USDC user, reserve income is not a separate interest payment credited to the token balance. The economic benefit appears inside Circle’s issuer business and is shared, in part, with distribution partners. Holding USDC does not by itself entitle a user to Circle’s reserve yield under the arrangements described in these filings.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsFor a platform, distribution can be valuable even when the platform does not issue USDC. Supporting deposits, withdrawals, trading pairs and payments can qualify the platform for negotiated economics, while greater balances can affect the allocation formula. The trade-off is that partner revenue depends on contractual terms and on the continued scale of USDC activity.
For an analyst, the most informative measures are average daily circulation, average reserve yield, reserve-income growth, Coinbase-related distribution costs, other incentive payments and the proportion of USDC held across relevant platforms. Looking at only quarter-end supply can miss the daily averages that drive the payment base.
Key limitations when interpreting the figures
- Contract details are not one universal schedule. Coinbase’s residual split and other partners’ negotiated terms operate within different agreements.
- Company-reported figures have different evidentiary status. SEC filing numbers are financial-statement disclosures; figures from Circle’s 2026 article are management’s own current claims.
- Dates matter. The 2% Circle, 12% Coinbase and 86% outside-platform snapshot applies to December 31, 2023, not every period.
- One-time payments can distort a year. The $60.25 million Binance fee in 2024 was described as upfront and one-time.
- Gross and net figures are different. Reserve income precedes reserve-management expenses and partner distributions; Circle’s retained economics come later in the waterfall.
The bottom line on Circle’s USDC revenue sharing
Circle primarily makes money from the income generated by assets backing USDC. In 2022–2024, that reserve income supplied 95%–99% of total revenue. Circle then uses a contractual waterfall: it keeps an issuer portion, allocates amounts linked to platform balances, pays approved participants under negotiated arrangements and gives Coinbase 50% of the residual payment base after specified deductions. The model expands when USDC circulation or reserve yields rise, but partner costs can rise at the same time. Understanding both sides of that equation—reserve earnings and distribution sharing—is essential to interpreting Circle’s USDC profitability.
