Analysts at investment bank Mizuho have revised their assessment of Circle Internet Group, the issuer of the USDC stablecoin. The company's stock price target was lowered from $45 to $43 while maintaining an "underperform" rating. This decision reflects growing expert concern about the structural challenges that Circle's business model may face in the medium term.

The key pressure factor — autonomous AI agents

The focus of analysts' attention was a new class of threats related to the development of autonomous AI agents. As intelligent systems gain increasing autonomy in conducting transactions, a fundamental question arises: will the dominance of traditional stablecoins as a settlement instrument for machine payments persist?

AI agents capable of initiating and executing operations without direct human involvement are creating demand for a new type of payment infrastructure. This creates a competitive field where stablecoin issuers may face pressure from alternative solutions — both programmable payment protocols and internal corporate settlement systems.

What this means for Circle's business model

Circle's economics traditionally rely on income from the reserves backing USDC, as well as on expanding the stablecoin's share of payment turnover. If a significant portion of transaction flow in the AI agent segment shifts to competing infrastructures, this could limit the issuer's revenue growth potential and weaken its position in the "money for machines" narrative.

The $2 reduction in the price target while maintaining a negative rating signals that the market is not yet pricing in a premium for Circle's leadership in the new payment paradigm. Investors should closely monitor how the company adapts USDC to autonomous agent settlement scenarios.

Cryptalist analysis: The revision of Circle's valuation reflects a broader trend — the market is beginning to reassess the resilience of stablecoin issuers' business models amid the emergence of the agent economy. Cryptalist's position is that USDC's ability to integrate into machine payment infrastructure will become the decisive factor in the company's long-term value, and the current price target correction is an early signal of risk reassessment rather than the final point in the sector's valuation.
