USDC (USDC)

USD Coin (USDC) is a dollar-pegged stablecoin issued by Circle Internet Group, a publicly traded financial technology company. Launched in September 2018 through a consortium called Centre, founded jointly by Circle and the cryptocurrency exchange Coinbase, USDC is generally regarded as the leading example of a "regulated" or "compliance-first" stablecoin, distinguished from rivals chiefly by its reserve composition, its custody arrangements with mainstream financial institutions, and its practice of publishing monthly attestations audited by a Big Four accounting firm.¹² As of July 2026, USDC had a circulating supply of approximately $73 billion, making it the second-largest stablecoin behind Tether's USDT, while capturing a majority share — roughly 70% in the first half of 2026 — of adjusted stablecoin transaction volume as tracked by Visa's Allium analytics platform, and had processed more than $90 trillion in cumulative onchain transaction volume since launch.³⁴⁵

Overview

Circle describes USDC as "fully reserved," meaning each token in circulation is backed by an equivalent value of cash and short-duration U.S. government securities held in segregated accounts on behalf of USDC holders, rather than by the kind of more varied asset mix — including commercial paper, secured loans, gold, or Bitcoin — that some competing stablecoins have used at various points in their history.⁶⁷ The large majority of USDC's reserves are held in the Circle Reserve Fund (ticker USDXX), an SEC-registered government money market fund managed by the asset manager BlackRock, with the remainder held as cash deposits at a small number of major global banks.¹⁷ Unlike some other major stablecoins, USDC generally does not offer a native yield to token holders; instead, interest earned on the underlying reserve portfolio accrues to Circle itself, forming the substantial majority of the company's revenue.⁸

USDC is issued natively on more than thirty blockchain networks, including Ethereum, Solana, Base, Avalanche, and Arbitrum, and Circle operates a Cross-Chain Transfer Protocol (CCTP) that allows USDC to move between supported chains by burning tokens on the source chain and minting an equivalent, natively issued amount on the destination chain, rather than relying on third-party bridge contracts that have historically been a common source of exploits in the broader crypto industry.¹⁹ This native, protocol-level interoperability is frequently cited by developers as an advantage over "wrapped" versions of other stablecoins that rely on external bridges, since a wrapped asset's peg depends on the continued security of the bridge holding the underlying collateral, whereas CCTP transfers always resolve to genuine, Circle-issued USDC on the destination chain.⁹

History

Founding and early years (2013–2018)

Circle was founded in October 2013 in Boston by Jeremy Allaire and Sean Neville, with early venture funding from investors including Accel Partners, General Catalyst, and Jim Breyer.¹⁰¹¹ Allaire was already a serial internet entrepreneur by that point, having previously co-founded the software company Macromedia (maker of the Flash multimedia platform) and later founded the video-technology company Brightcove, which itself went public in 2012.¹² The company initially focused on consumer-facing payments and a peer-to-peer crypto wallet product rather than stablecoin issuance, and in September 2015 became the first company to receive a BitLicense from the New York State Department of Financial Services, at the time widely regarded as one of the most difficult cryptocurrency licenses to obtain.¹³¹¹ Circle progressively narrowed its focus toward stablecoin infrastructure over the following years; Sean Neville stepped down as co-CEO in 2019, leaving Allaire as sole chief executive.¹⁰¹³

USDC itself launched in September 2018 under the governance of Centre, a consortium initially envisioned as a broader industry standard-setting body but which, in practice, came to include only Circle and Coinbase as formal members.¹³¹² Circle and Coinbase shared revenue generated from USDC's reserve interest according to the proportion of USDC each company held or distributed.¹³

Growth, SPAC attempt, and a first regulatory test (2020–2023)

USDC's circulating supply grew rapidly alongside the broader decentralized finance boom, expanding from under $1 billion in 2020 to more than $50 billion by 2022.¹³¹² Visa announced in March 2021 that it would accept USDC for transaction settlement, an early and significant instance of mainstream payments infrastructure integrating a stablecoin directly.¹⁴ In July 2021, Circle announced plans to go public through a $4.5 billion merger with a special-purpose acquisition company, Concord Acquisition Corp, a deal that was revised to a $9 billion valuation in early 2022 before being terminated altogether in December 2022 amid deteriorating crypto-market conditions following the collapses of Terra/Luna, Celsius, and FTX, as well as delays in SEC review.¹⁰¹¹

In late 2022, Circle restructured USDC's reserve management, moving custody of a substantial majority of reserves — previously held largely at the Bank of New York Mellon — into the newly created Circle Reserve Fund, managed by BlackRock and invested in short-dated U.S. Treasuries and Treasury repurchase agreements.¹⁰ That December, Circle also partnered with the United Nations High Commissioner for Refugees to distribute USDC to Ukrainian refugees, who could convert the tokens into local currency, an early example of the token's use in humanitarian and cross-border payment contexts.¹⁰

USDC's most severe test to date came on March 10, 2023, when Silicon Valley Bank (SVB) was seized by regulators; Circle disclosed that $3.3 billion of USDC's roughly $40 billion in reserves — about 8% of the total — was held at SVB at the time of its failure.¹⁰¹⁵ USDC's price fell as low as approximately $0.87–$0.88 over the following weekend as investors redeemed a net $6 billion from the token in a matter of days, before recovering fully to its dollar peg once U.S. regulators announced that all SVB depositors, including Circle, would be made whole.¹⁵¹⁶ USDC's circulating supply nonetheless continued declining in the aftermath, falling to roughly $24 billion by late 2023 as confidence in the token took months to rebuild, while rival stablecoin USDT — which had no direct U.S. banking exposure of this kind — gained substantial market share during the same period.¹⁶

Consolidation and renewed growth (2023–2024)

Centre was formally wound down in August 2023, with Circle assuming full operational responsibility for USDC and Coinbase taking a minority equity stake in Circle itself as part of a revised, more evenly split revenue-sharing arrangement.¹³¹² Circle spent much of 2023 and 2024 in what several industry analysts characterized as a rebuilding phase, cutting staff, divesting non-core investments, and narrowing its business focus almost entirely to stablecoin infrastructure; the company returned to solid profitability during this period, reporting $1.45 billion in revenue and $268 million in net income for 2023, followed by $1.68 billion in revenue and $156 million in net income for 2024.¹⁰¹⁷ In February 2024, Circle discontinued support for USDC on the Tron network, and by April 2024, data from Visa's analytics showed USDC had overtaken USDT in stablecoin transaction volume for the first time, even though USDT continued to lead by total circulating supply.¹⁰ Circle also entered a partnership with Binance in December 2024 to promote USDC adoption and encourage the exchange to hold USDC as part of its own reserves.¹⁰

Initial public offering (2025)

Circle filed confidentially for an initial public offering in early 2025 and publicly filed its S-1 registration statement in April 2025, having reportedly declined acquisition interest from both Coinbase and Ripple Labs, including a Ripple bid valued at $4 billion to $5 billion that Circle's board considered too low.¹²¹⁷ Circle listed on the New York Stock Exchange under the ticker CRCL on June 5, 2025, pricing its IPO at $31 per share — above its initially marketed range — and raising approximately $1.05 billion; shares opened at $69, closed the first day at $83 (a gain of roughly 168%), and traded as high as $103.75 during the session, later reaching an intraday peak near $290 in the weeks that followed.¹⁷¹⁸ The offering was widely described as the most significant U.S. crypto-industry public listing since Coinbase's own 2021 debut, and made Allaire a billionaire on paper.¹⁷ Analysts noted that Circle's distribution costs remained substantial even after the IPO, with the company paying more than $1 billion in total distribution fees in 2024 alone, including roughly $900 million to Coinbase, a structural cost that stood in contrast to Tether's comparatively lean distribution model.¹⁷

In July 2025, the United States enacted the GENIUS Act, establishing the country's first comprehensive federal licensing framework for "payment stablecoins."¹⁹ Because Circle's reserve, custody, and disclosure practices already closely resembled the framework's requirements, Circle was widely regarded as well-positioned to qualify for federal licensure under the new law, and CEO Jeremy Allaire — who had lobbied for stablecoin-specific legislation since at least 2023 — publicly welcomed the law's passage as validating Circle's longstanding, compliance-oriented strategy.¹⁹²⁰

Institutional integration and continued growth (2025–2026)

Through late 2025 and into 2026, Circle deepened its integration with traditional financial institutions. USDC's circulating supply grew roughly 80% over the two years to early 2026, reaching approximately $73–75 billion, with quarterly onchain transaction volume reported at nearly $12 trillion by the end of 2025.¹¹¹² In late June and early July 2026, Standard Chartered became the first global systemically important bank to offer institutional clients integrated USDC minting and redemption without requiring a separate Circle account, and BNY Mellon expanded its relationship with Circle to make USDC the first stablecoin available on its Digital Asset Custody platform.²¹ On July 10, 2026, the U.S. Office of the Comptroller of the Currency granted Circle approval to establish a national trust bank, Circle National Trust, providing fiduciary digital-asset custody services under direct federal supervision — part of a broader wave of similar national trust charters granted to crypto infrastructure companies including BitGo, Ripple, Paxos, and Crypto.com around the same period.²² By that point, Visa's analytics showed USDC capturing approximately 70% of adjusted stablecoin transaction volume in the first half of 2026, versus roughly 25% for USDT, even though USDT continued to lead by total circulating market capitalization.⁵²²

This division of Circle's development into a wallet-and-payments phase followed by a narrower stablecoin-infrastructure focus has since been cited by industry observers as an early, and ultimately successful, pivot toward a more durable and regulator-friendly business model than the company's original consumer-payments ambitions.¹¹

Reserves, technical design, and business model

USDC's reserves are held separately from Circle's own corporate operating funds, primarily within the Circle Reserve Fund — a 2a-7 registered government money market fund holding cash, short-dated U.S. Treasuries, and overnight Treasury repurchase agreements — with the remainder held as cash deposits at a small number of large global banks.¹⁷ Circle publishes monthly attestation reports prepared by Deloitte & Touche confirming that reserve assets meet or exceed the value of outstanding USDC, a more frequent cadence and a higher-tier accounting firm than some competing stablecoin issuers use for their own disclosures.²¹¹ The USDC smart contract includes a blacklist function allowing Circle to freeze tokens held at specific addresses, a capability the company has used in response to U.S. Treasury Department sanctions — most notably against the Tornado Cash mixing service in 2022 — and in cases involving reported stolen funds; Circle has described this as a documented compliance capability rather than a hidden one.²

Because USDC does not pass reserve interest through to token holders, Circle's revenue is derived almost entirely from the interest income generated by its reserve portfolio — a structure that leaves the company's earnings closely tied to prevailing U.S. interest rates and exposed to any decline in short-term rates, a risk factor Circle has itself disclosed to investors.¹²¹⁷ This revenue arrangement is split substantially with Coinbase under the companies' post-Centre agreement, making distribution costs one of the largest single expenses in Circle's business.¹⁷

Market history

USDC has generally traded very close to its $1.00 peg, with an all-time high of $1.04 recorded shortly after launch in November 2018 and an all-time low of approximately $0.877 recorded during the March 2023 Silicon Valley Bank crisis, the only period in the token's history in which it deviated substantially from its peg.²³²⁴ USDC's market share relative to USDT has fluctuated considerably over time, generally rising during periods when confidence in stablecoin transparency and regulatory compliance is high, and falling during periods of stress that affect USDC specifically (such as the SVB episode) or benefit less U.S.-banking-dependent competitors.¹⁶ As of July 2026, USDC's circulating supply stood at roughly $73 billion, with a corresponding market capitalization near that figure and reserves reported to modestly exceed outstanding supply.³⁴

Positive contributions and institutional standing

USDC's history has been shaped substantially by a deliberate strategy of prioritizing regulatory engagement and transparency well before such compliance was commercially necessary, including Circle's early pursuit of licenses across dozens of jurisdictions, its shift toward conservative, Treasury-heavy reserves ahead of most competitors, and Allaire's public, multi-year advocacy for federal stablecoin legislation in the United States.¹¹¹⁹²⁰ That strategy has since been credited with positioning Circle favorably as regulatory frameworks including the GENIUS Act in the U.S. and MiCA in the European Union came into force, culminating in Circle's 2026 approval for a national trust bank charter and a growing list of integrations with systemically significant banks such as BNY Mellon and Standard Chartered.¹⁹²² USDC's practical use cases have also expanded meaningfully beyond crypto trading, including its role in humanitarian remittance efforts such as the 2022 partnership distributing funds to Ukrainian refugees, and its adoption by major payment networks, including Visa and Mastercard, for institutional settlement.¹¹⁰¹⁴ Supporters of Circle's approach have argued that USDC's relatively slower growth and higher compliance costs compared with less-regulated competitors reflect a genuine trade-off in favor of durability and institutional trust, a proposition that gained considerable market validation once USDC overtook USDT in monthly transaction-volume share during 2026.⁵¹⁷

Criticism and risks

USDC's 2023 depegging during the Silicon Valley Bank collapse remains the most significant blemish on its transparency-focused reputation, illustrating that even a stablecoin with comparatively conservative, bank-custodied reserves carries real counterparty risk tied to the health of the traditional banking institutions where those reserves are held — a risk that, in Circle's case, was realized and required a federal regulatory intervention (the FDIC's backstop of SVB depositors) to fully resolve.¹⁵¹⁶ Circle's heavy reliance on distribution partners, and the substantial share of USDC-related revenue paid out to Coinbase under their revenue-sharing arrangement, has also been cited by analysts as a structural drag on Circle's margins relative to issuers such as Tether that do not rely on comparable third-party distribution deals.¹⁷ More broadly, because Circle's revenue is drawn almost entirely from reserve interest income, some analysts have flagged the company's earnings as unusually sensitive to future interest-rate declines, a dynamic that contributed to a sharp, double-digit-percentage drop in Circle's stock price when a large competing "open" stablecoin initiative was announced in mid-2026.²⁵ The blacklist and freeze functionality built into USDC's smart contract, while broadly framed by Circle as a necessary sanctions-compliance tool, has also drawn recurring criticism from parts of the cryptocurrency community as evidence of meaningful centralization inconsistent with the permissionless ethos of public blockchains more broadly — a critique that applies to most major regulated stablecoins, not uniquely to USDC.²

Circle's dependence on favorable interest-rate conditions and continued institutional partnerships also means that, unlike Tether — which has diversified into Bitcoin, gold, and a range of unrelated corporate investments — Circle's business model remains comparatively concentrated around a single core product, a trade-off that supporters characterize as commendable focus and critics characterize as limited diversification against future shifts in the regulatory or interest-rate environment.¹²¹⁷
