Coinbase reported a record $20 billion in average USDC held across eligible products in the second quarter, but the larger balance base did not prevent stablecoin revenue from declining as lower interest rates reduced the economics of those holdings.
The company recorded $292.1 million of stablecoin revenue for the three months ended June 30, down 5% from $308.9 million a year earlier. In its quarterly filing, Coinbase said lower average interest rates reduced stablecoin revenue by $55.9 million year over year, partly offset by higher average USDC balances held by customers in eligible products.
For payments companies, the result separates two measures that are often treated as though they move together: the amount of stablecoin liquidity held on a platform and the revenue that the platform earns from that liquidity. Coinbase expanded its USDC balance base while earning less stablecoin revenue than in the comparable quarter.
USDC balances grew as rates pressured revenue
Coinbase defines its average USDC held in products as corporate USDC balances plus USDC held on behalf of customers in eligible Coinbase products. The company said the quarterly average reached an all-time high of $20 billion, up from $19 billion in the first quarter and $14 billion a year earlier.
Its earnings presentation also said more than 30% of USDC in circulation was held in Coinbase products at quarter-end. Both the record and the circulation share are company-calculated operating metrics, not independently audited measures of payment volume or merchant adoption.
The distinction matters because stablecoin revenue is sensitive to more than balances. Coinbase earns economics connected to USDC through its arrangement with Circle, and the yield available on reserve-linked assets changes with interest rates. A larger balance base can therefore coexist with lower revenue when average rates decline. The filing does not disaggregate how much of the $292.1 million came from individual Coinbase products or payment use cases.
An accounting change narrows what the stablecoin line captures
Coinbase revised its presentation in the first quarter of 2026 so that revenue earned on corporate payment-stablecoin balances appears in corporate interest and other income rather than in stablecoin revenue. The company reclassified the comparable 2025 figures and said the presentation change did not alter total revenue or its arrangement with Circle.
That treatment means the reported stablecoin-revenue line should not be read as the full economic contribution from every stablecoin balance controlled or managed by Coinbase. It primarily captures stablecoin revenue within subscription and services, while income from the company’s own payment-stablecoin cash-equivalent balances is reported elsewhere.
Payments and treasury teams comparing platforms should therefore examine definitions and classification changes rather than relying on a single headline number. Revenue attributed to stablecoins can include balance-linked economics that respond to rates, while transaction, conversion, custody and software revenue may be recorded in other categories.
Stablecoins provided scale, not immunity from a weaker quarter
Coinbase reported $555.1 million in subscription and services revenue, equal to 48% of net revenue, compared with $632.2 million a year earlier. Transaction revenue was $599.2 million, down from $764.3 million. Net revenue was $1.15 billion, and the company recorded a GAAP net loss of $359.5 million.
Independent coverage by Cointelegraph described the quarter as mixed, noting weaker trading activity alongside Coinbase’s broader expansion into derivatives, tokenized assets and payments. Coinbase’s own presentation places stablecoins and payments among its three priorities for 2026 and lists products and updates including custom stablecoins, direct deposit, a card, x402 and a merchant-acceptance suite.
That product list shows the intended breadth of the strategy, but it is not evidence that every capability is available to every customer or that the products operate as one integrated payment system. Coinbase says availability varies by jurisdiction, eligibility, affiliate and applicable approvals.
What payment providers should watch
The quarterly figures make interest-rate exposure a central operating question for stablecoin platforms. Providers that rely on reserve or balance economics may need transaction fees, software revenue or other services to offset lower yields. Customers evaluating those providers should ask how revenue is split among balances, conversion, custody, settlement and merchant services.
Liquidity concentration also deserves attention. Holding more than $20 billion of average USDC across corporate and customer balances can support conversions, settlement and product distribution, but it also increases the importance of custody controls, redemption access, counterparty arrangements and service continuity. The earnings materials do not provide product-level payment volume, merchant count, settlement-time performance or fee data for Coinbase’s payment products.
Coinbase’s Q2 disclosure therefore supports a narrower conclusion than a general claim that stablecoin payments are insulating the business from market cycles. USDC balances on the platform increased materially, but stablecoin revenue still fell as rates moved against it. The next test is whether payment and software activity can produce more revenue that is tied to usage rather than primarily to balance levels and interest rates.
