Circle is mounting a public defense of its USDC business model as stablecoin competitors move to offer distribution partners a larger share of reserve income. The debate intensified after Coinbase, Circle's largest distribution partner, backed Open USD alongside Stripe and BlackRock, sharpening a contest over how issuers balance partner incentives, operating expenses, and profitability.

Kash Razzaghi, Circle's Chief Commercial Officer, laid out the company's first-half 2026 financial figures on October 16. Circle's revenue came to approximately $1.4 billion, with $819 million paid out in distributor payments and fees, according to Circle's blog post and accompanying SEC disclosures. The breakdown offers a detailed public view of how a major stablecoin issuer divides revenue between partner payouts and operating costs — the trade-off now driving competition across the sector.

The tension did not go unnoticed among market observers:

Circle defends USDC economics while Coinbase—its largest USDC partner—backs Open USD, which passes reserve income to partners after a fee. If revenue-sharing matters, that's a loud signal. 💸 #Crypto #CryptoNews

USDC Economics Reflect Infrastructure and Redemption Costs

According to Circle's breakdown, 59 cents of every revenue dollar went to distribution partners and fees. Another $473 million — roughly 34 cents per revenue dollar — was spent on compliance, liquidity, licensing, banking, and product development, a figure that includes about $214 million in stock-based compensation and related expenses.

Razzaghi characterized these outlays as necessary to build the infrastructure that allows USDC to operate across financial institutions, payment channels, and blockchains. He noted that any issuer must maintain banking connections, licensing, and liquidity to make redemptions possible, and that such expenses are required regardless of how issuers compensate their partners.

"Redemption, compliance, and resilience costs do not simply go away if the issuer chose not to pay for them," Razzaghi wrote. The statement speaks to the financial problem confronting all stablecoin issuers as new networks promise participants a greater share of reserve revenue.

USDC Economics Evolve as Rivals Share Revenue

Open USD was introduced in June 2026 by Coinbase, Stripe, and BlackRock, according to the project's launch announcement. The model is designed to give businesses the ability to mint and redeem stablecoins for free while distributing reserve revenue among participants, minus a management fee. The network's OUSD token is now live, adding another competitor to the market.

The approach departs from the way most stablecoin issuers structure relationships with distribution partners. Reserve income — the yield earned on the assets backing a stablecoin — has long anchored issuer economics, funding operations and, at times, being shared with the businesses involved in promoting the tokens. Because that yield comes from interest earned on reserve assets, the income available to issuers — and to share with partners — moves with prevailing interest rates.

Circle, for its part, did not specifically mention Open USD in its blog post published on October 16, 2026. Instead, the company outlined partner participation in USDC economics through the balances partners hold on their platforms, claiming that partners that bring in and grow USDC balances earn a share of the reserve income those balances generate.

The Paxos-operated Global Dollar Network, which issues the USDG stablecoin, likewise shares reserve income among participants. Taken together, these models give exchanges, fintech firms, and payment businesses a wider set of options when selecting stablecoin partners.

Transaction Volume Strengthens Circle's Case

Circle reported more than $36 trillion in USDC on-chain transaction volume during the first six months of 2026. The company additionally noted that USDC was involved in over $315 billion of minting and redemptions, averaging approximately $1.7 billion per day. In June 2026, USDC accounted for about 77% of transaction volumes across all stablecoins worldwide, up from 60% a year earlier.

Those figures frame Circle's rationale for its distribution spending and infrastructure investment, which the company credits for USDC's market positioning. According to Circle, more than 150 partners have an interest in promoting USDC, spanning exchanges, wallets, banks, fintech companies, payment solutions, and enterprises.

In its second-quarter earnings report, Coinbase disclosed that the average value of USDC stored across its products reached a record $20 billion, growing 44% year over year. Nevertheless, Coinbase's position as one of Open USD's biggest partners shows that a distribution partner can hold a stake in a competing stablecoin without severing its ties to USDC.

The overlap extends beyond Coinbase. In September 2026, Binance committed to invest $100 million in Circle over the next five years, conditioned on receiving a fee tied to USDC stored through Circle's wallet solution.

Circle Highlights Payments and Redemption Infrastructure

Circle said standard USDC redemptions remain free for customers and typically settle within two business days through standard banking rails. Beyond standard transactions, Circle also offers free, near real-time redemptions of USDC to eligible users via the Circle Payments Network and other qualifying Circle Platform services, according to the company's terms.

Fast transactions, however, require payment liquidity outside banking hours. According to Circle, maintaining that liquidity is necessary to process payments and redemptions at different points in the day.

The competition now extends beyond stablecoin availability to partner revenue, redemption speed, and operating costs. Circle's USDC continues to post large-scale transaction volumes and maintains an established distribution network, while Open USD and USDG offer alternative approaches to reserve-income sharing. Businesses evaluating these networks will weigh financial incentives against liquidity, compliance, and settlement needs as the market develops. Disclosures of the kind cited here, from both issuers and distribution partners, will provide a running record of how balances and revenue-sharing terms shift across competing networks.
