"Stablecoins that distribute everything and fund nothing" — Kash Razzaghi, Chief Commercial Officer, Circle Internet Group
Circle Internet Group (NYSE: CRCL) disclosed on October 16 that it retained approximately 7 cents of net profit for every dollar of first-half 2026 revenue, after paying $819 million — 59% of total intake — to distribution partners and transaction costs. The filing lays bare the structural economics of the world's second-largest stablecoin: USDC settled more than $36 trillion in on-chain volume during H1 2026 and captured 77% of global stablecoin transaction volume by June, yet the issuer's net margin sits below 7%.
The disclosure arrives as Circle trades at a $21 billion market capitalization, roughly 15x annualized revenue, while privately held Tether reported $1.5 billion in Q2 2026 profit alone on a supply base 2.5x the size of USDC's. The gap illuminates a fundamental question in stablecoin economics: whether Circle's distribution-dependent model can ever approach the margin profile of an issuer that retains virtually all reserve income.
Circle generated approximately $1.4 billion in total revenue and reserve income during the first six months of 2026. The company disclosed the following allocation per dollar of revenue:
| Allocation | Share | H1 2026 Amount (est.) | |---|---|---| | Distribution partners & transaction costs | 59 cents | ~$819M | | Licensing, compliance, infrastructure, product | 34 cents | ~$473M | | Net profit retained | 7 cents | ~$98M |
USDC's on-chain footprint during the period: more than $36 trillion in settled transaction volume. The issuer processed approximately $315 billion in token issuance and redemptions — roughly $1.7 billion per day. According to Circle, the company's partner network exceeded 150 participants by mid-year.
USDC's circulating supply ended Q2 at $73.3 billion, up 19% year over year, with average circulation hitting an all-time high of $76.5 billion during the quarter.
The largest line item in Circle's cost structure is its revenue-sharing arrangement with Coinbase Global (NASDAQ: COIN). Under the terms renewed in August 2026 and extended through 2029, Coinbase receives 100% of reserve interest income generated by USDC held on its platform and 50% of residual reserve income from USDC circulating elsewhere, after Circle's issuer allocation and other partner deductions.
In 2024, Circle paid Coinbase $908 million — approximately 54% of that year's revenue — for USDC distribution, according to regulatory filings. The H1 2026 figure of $819 million across all partners suggests the annual run rate has grown alongside USDC supply, though the per-dollar cost has remained structurally fixed near 59% since at least fiscal year 2024, according to beancount.io's earnings analysis.
Coinbase held an average of $20 billion in USDC during H1 2026, a 44% year-over-year increase. This concentration means Coinbase's position as the single largest USDC custodian gives it persistent leverage in revenue negotiations. CEO Jeremy Allaire confirmed on Circle's Q2 earnings call (August 5, 2026) that the agreement continues under original terms.
Circle's Q2 2026 earnings, reported August 5, provided granular visibility into the economics:
The year-over-year net income swing of $530 million was almost entirely attributable to a $503.4 million IPO-related stock compensation charge in Q2 2025 that did not recur. Stripping out that one-time item, operational profitability improved modestly.
Adjusted operating expenses rose 23% year over year to $146 million, with compensation at $134 million and IT infrastructure at $16.4 million. Management characterized the quarter as reflecting "the current rate environment and crypto market that has slowed."
The economic difference between the two dominant stablecoin issuers is stark.
| Metric | Tether (USDT) | Circle (USDC) | |---|---|---| | Circulating supply (Sept. 2026) | ~$183.4B | ~$74.2B | | Market share | ~59% | ~23% | | Q2 2026 profit | $1.5B | $48.2M | | Q1 2026 profit | $1.04B | ~$50M (est.) | | 2025 full-year profit | >$10B | $157M | | Revenue-sharing model | Minimal partner splits | 59% to partners | | U.S. Treasury holdings | >$141B | ~$73B (reserves) |
Tether's reserve portfolio — more than $141 billion in U.S. Treasury bills at yields above 4% — generates multi-billion-dollar annual returns. Because Tether does not operate a comparable distribution revenue-share, it captures nearly all reserve yield as profit. Tether remains privately held and does not file with the SEC; its figures are self-reported through quarterly attestations.
Circle's transaction volume advantage — USDC handled $18.3 trillion in on-chain volume during 2025 versus USDT's $13.3 trillion, according to industry data — has not translated into a profitability advantage. Volume leadership and margin leadership diverge because Circle pays for distribution while Tether's exchange integrations impose lower direct costs.
A structural risk visible in Q2 data: Circle's reserve return rate declined 66 basis points quarter over quarter to 3.5%. With the U.S. Federal Reserve holding rates steady through mid-2026 — and market expectations of potential cuts in late 2026 or early 2027 — Circle's single-source revenue dependency on Treasury yields faces headwinds.
At $76.5 billion average circulation and a 3.5% annualized yield, gross reserve income runs at approximately $2.68 billion annually. A 100-basis-point decline in yields would reduce that figure by roughly $765 million — an amount nearly equal to the company's entire H1 distribution costs.
The company's FY2026 guidance update, issued alongside Q2 results, projected other revenue of $310–$330 million (raised from $150–$170 million), RLDC margin of 41.7%–43.7%, and adjusted operating expenses of $570–$585 million. The guidance raise was partly driven by Arc, Circle's programmable wallet platform, which recorded a $242 million token presale recognized as deferred revenue.
Circle launched CPN Managed Payments on April 8, 2026 — a full-stack stablecoin settlement service enabling banks, payment service providers, and enterprises to settle cross-border transactions in USDC without directly managing digital assets. The platform supports payouts across more than 20 blockchains and domestic payment rails.
Other revenue — which includes CPN, blockchain partnerships, and subscription services — grew 41% year over year to $33.6 million in Q2. At $134 million annualized, this line item remains small relative to the $2.67 billion annualized reserve income. Circle's ability to scale non-reserve revenue will determine whether the company can reduce its rate sensitivity.
An additional distribution channel materialized on October 7, when Samsung Electronics America announced USDC transfers would launch in Samsung Wallet during the last week of October 2026. The integration, running on Solana infrastructure with Coinbase Prime as sub-custodian, will make USDC accessible across 82 million U.S. Galaxy devices, with cross-border payouts to bank accounts in more than 60 countries. Samsung said it will charge no fees for wallet-to-wallet transfers.
Circle's stock (CRCL) traded at $81.96 on October 16, down from a 52-week high of $147.44 but above its $31 IPO price from June 2025. The company's IPO raised $1.1 billion, valuing Circle at $6.9 billion. Shares surged 168% on their first trading day; they have since given back a portion of those gains, with the stock down approximately 67% from its peak, according to ValueAddVC analysis.
On the regulatory front, the European Banking Authority classified USDC as a "significant" e-money token under MiCA on October 14 — the first stablecoin to cross that threshold among the EU's 45 MiCA-notified e-money tokens. This designation brings direct EBA supervisory oversight of USDC reserves within the EU.
In the United States, the GENIUS Act stablecoin legislation continues to advance. Circle's disclosure of its cost structure was explicitly positioned as a counter to emerging competitors — Razzaghi characterized rival models as "stablecoins that distribute everything and fund nothing," arguing that compliant stablecoin issuance requires substantial investment in licensing, compliance, and infrastructure that thin-margin entrants may not sustain.
Circle's October 16 disclosure provides the clearest public accounting of stablecoin unit economics available from any major issuer. The numbers confirm what SEC filings had already suggested: USDC is a high-volume, low-margin product whose profitability depends on two external variables — U.S. Treasury yields and the Coinbase distribution agreement.
At 59 cents per revenue dollar flowing to partners, Circle's path to margin expansion is narrow. Non-reserve revenue must scale by an order of magnitude to materially alter the company's cost structure. The CPN launch, Samsung distribution, and Arc platform represent early-stage bets on that diversification.
For the broader stablecoin market, Circle's data establishes a benchmark: compliant, regulated stablecoin issuance in the United States currently generates single-digit net margins. Whether that margin is sufficient to sustain infrastructure investment at scale — or whether Razzaghi's warning about underfunded competitors proves prescient — will become visible as the GENIUS Act framework takes shape and new issuers enter the market.
