Mizuho downgraded Circle Internet Group (CRCL) from Neutral to Underperform on July 14, slashing its price target from $85 to $50. The bank also cut its 2027 adjusted EBITDA forecast for Circle to $699 million, roughly 25% below the Wall Street consensus of $941 million and well below the firm's prior estimate of $1.09 billion. Circle shares were trading near $61.73 on Monday, already down sharply from a 52-week high of $262.97. JPMorgan separately lowered earnings estimates for both Circle and Coinbase the same day, citing the Hyperliquid revenue-sharing deal and weaker crypto trading volumes as the primary drivers.

The Cost of Keeping Partners Happy

Circle's business is built on what analysts call "float capture": the company backs every USDC token with U.S. Treasury securities and money market instruments, and retains a portion of the yield those reserves generate. After sharing income with distribution partners, Circle keeps roughly 38 cents of every dollar earned. Mizuho now estimates Circle's combined distribution and transaction costs have risen to 73% of revenue, up from a prior estimate of 64%.

A major driver of that increase is a May 2026 agreement with Hyperliquid, the largest on-chain perpetual futures exchange by trading volume. Hyperliquid's trading volume exceeded $150 billion in July 2026, representing approximately 11.5% of Binance's volume, which gives a sense of the counterparty's scale and its ability to negotiate favorable terms. Under the deal, USDC became Hyperliquid's Aligned Quote Asset (AQA), its formally designated primary settlement currency. Coinbase serves as the treasury deployer for the USDC held on the Hyperliquid platform, while Circle retained only minting and cross-chain responsibilities. That structural split matters: it explains both the lopsided economics and Coinbase's later dual role as an Open USD backer. The economic terms are harsh for Circle: Hyperliquid captures up to 90% of the reserve income generated by the roughly $6 billion in USDC held on its platform. Compass Point estimates the arrangement redirects between $135 million and $160 million in annual reserve income away from Circle and Coinbase, reducing their combined EBITDA by $60 million to $80 million per year.

JPMorgan analysts described the situation as a "prisoner's dilemma." In a note on Monday, Kenneth Worthington and his team wrote: "We think the change in the Hyperliquid relationship showcases the [prisoner's dilemma] challenge inherent in partnership structures." Circle and Coinbase must accept punishing revenue-sharing terms or risk losing market share to Tether (USDT) or a competing stablecoin. Neither outcome is good for shareholders.

Open USD Adds a Structural Threat

Compounding the near-term pressure is a longer-term competitive challenge. On June 30, a consortium of more than 140 companies, including Visa, Mastercard, Stripe, BlackRock, BNY, U.S. Bank, and Coinbase, announced Open USD (OUSD), a new dollar-pegged stablecoin issued by an independent entity called Open Standard. Open Standard is led by Zach Abrams, co-founder of Bridge, the payments infrastructure company acquired by Stripe for $1.1 billion. That acquisition explains Stripe's presence in the consortium and establishes Abrams's standing within the payments ecosystem. Unlike Circle, which retains a significant share of reserve yield, Open Standard's model passes nearly all of that yield through to minting partners and distributors.

Mizuho analysts wrote that Open USD "could fundamentally alter Circle's business model, which relies on retaining a large portion of the treasury yield." The new stablecoin is expected to launch later in 2026 on Solana, Stellar, Base (Coinbase's Layer 2 network), and Polygon. Notably, Coinbase, which is Circle's largest USDC distributor and due to renew its revenue-sharing agreement with Circle in August 2026, is also an Open USD backer. Coinbase's overlapping roles as Circle's biggest distribution partner, an Open USD consortium member, and the operator of one of Open USD's launch chains represent precisely the kind of competitive threat that Mizuho's analysis highlights.

OCC Approval Offers Little Relief

Circle did secure a meaningful regulatory milestone on July 10, when the U.S. Office of the Comptroller of the Currency approved the company to establish First National Digital Currency Bank, N.A., operating as Circle National Trust. The federal charter allows Circle to provide regulated custody for digital assets and to manage USDC reserves under federal oversight. Circle shares jumped 11% on the news. Mizuho acknowledged the approval but said it "doesn't solve USDC growth or stablecoin competition risks," and the stock subsequently erased much of those gains following the downgrade.

Why Emerging Markets Are Exposed

The pressure on Circle's margins has implications well beyond U.S. equity markets. USDC's circulating supply has fallen from roughly $80 billion in March 2026 to approximately $73 billion as of July, a $7 billion decline. That contraction does not reflect Circle-specific problems alone: the broader stablecoin market contracted by approximately $10 billion since May 2026, driven by softer crypto trading activity across the sector. Even so, USDC accounted for approximately 70% of stablecoin transaction volume in the first half of 2026, outpacing USDT on that measure despite holding only about 24% of total stablecoin market capitalization.

That transactional footprint is especially significant in Africa and South Asia. Nigeria ranks first globally in stablecoin adoption according to a 2026 BVNK survey, with 48% of Nigerian crypto users holding USDC and 59% holding USDT, making both stablecoins widely held but with USDT carrying the larger share in that market. The same survey found that 95% of Nigerian and South African respondents prefer to receive payments in stablecoins over local currency, a figure that reflects how deeply inflation concerns have embedded stablecoins in everyday financial life. Nigeria, Kenya, and South Africa together account for 12% of global USDC peer-to-peer usage, and stablecoins represent roughly 43% of crypto transaction volume across Sub-Saharan Africa. In India, approximately 5.7 million wallet addresses have interacted with USDC, primarily through freelance and gig-economy payouts.

Fintech startups across these regions use USDC on Solana and Base to route remittances at near-zero cost. If Circle curtails distribution incentives to protect margins, those payment rails could shift toward USDT or, eventually, Open USD once it reaches full deployment. Cassava Technologies' Sasai Fintech, an existing Circle partner, has been identified in analyst research as a potential migrant to Open USD once it launches, illustrating how the competitive threat extends to named African partners. The IMF documented in June 2026 that USDC has become embedded in Nigeria's cross-border trade infrastructure, adding a layer of systemic relevance that goes beyond speculative trading.

What Comes Next

The August renewal of the Coinbase revenue-sharing agreement will be the most immediate test of Circle's ability to retain favorable terms with its most important partner. Open USD's launch timeline and the pace of USDC supply recovery will determine whether Monday's analyst downgrades reflect a temporary correction or the beginning of a structural re-rating. For Circle, the question is whether a federally chartered trust bank and a 70% share of global stablecoin transaction volume recorded in the first half of 2026 is enough leverage to hold its economic position together.
