Circle's 7-cents-per-dollar margin is the prize. Mizuho put the first bank price tag on what AI shopping agents do to a stablecoin issuer. In [a Monday research note](https://www.theblock.co/news/business/2026-10-27-mizuho-cuts-circle-price-target-431826), the brokerage cut [Circle Internet Group](https://theinference.org/markets/companies/circle) (CRCL), the company behind the USDC stablecoin, to $43 from $45 with an Underperform rating [1]. Circle's shares closed down 7% at $79.84 on Monday, leaving Mizuho's target implying 46% more downside. [1] ## Where a balance sits decides who collects The mechanism is the float. Circle earns reserve interest on USDC in circulation, and where a balance sits decides who collects. As of the second quarter, only 17% of USDC sat on Circle's own platform earning no yield, 30% sat on [Coinbase](https://theinference.org/markets/companies/coinbase), and 53% sat on other platforms, per Mizuho's report. [1] When an agent chooses where balances rest, it chooses Circle's revenue. *Chart: **Only 17% of USDC sits on Circle's platform, and it earns no yield** Pie chart splitting USDC in circulation by where it is held: 53% on other platforms, 30% on Coinbase, 17% on Circle's own platform.* *Share of USDC in circulation by where balances are held, Q2 2026. Holdings on Circle's platform earn no yield. Source: Mizuho research report via The Block, October 27, 2026. [1]* ## Agents steer holders out of USDC The analysts said AI personal assistant engines, including [Meta](https://theinference.org/markets/companies/meta)'s Muse, pose a "marked risk" to medium-term revenue. In their simulation, agents steer holders toward higher-yielding FDIC-insured alternatives such as [SoFi](https://theinference.org/markets/companies/sofi) savings accounts, and even when users insist on staying in crypto, the agents "seem to prefer other platforms." [1] Mizuho sizes a $4 billion to $9 billion hit to USDC's market cap, a 10-20% medium-term cut to reserve revenue, and cuts 2027 forecasts to $101 billion of USDC in circulation, $4.1 billion of reserve revenue and $603 million of adjusted EBITDA. [1] The stakes are real: Circle kept [roughly 7 cents of net profit per revenue dollar](https://theinference.org/article/circle-keeps-7-cents-per-dollar-of-revenue-and-its-cfo-just-sold-1-35-million-of-stock-at-90) on $1.4 billion of first-half revenue, with $36 trillion settled on USDC. [1] ## The other camp bought the same stock Bernstein [raised its Circle earnings estimates](https://cryptobriefing.com/bernstein-cuts-coinbase-target-raises-circle-outlook/) on USDC supply growth while keeping Outperform. [2] Ark Invest [bought 65,615 Circle shares for about $5.2 million](https://cryptobriefing.com/ark-invest-buys-circle-internet-group-shares/), adding to a top ARKK holding. [3] Circle reports Q3 on November 4. The reserve-revenue line is where the agent argument gets its first receipt. ## Takeaway Mizuho's cut is the first bank model of AI agents steering stablecoin balances toward yield; Circle's thin margin means who holds the float decides the stock. ## Sources 1.
