Circle CEO Says AI Agents Are Already Choosing USDC for Payments

Circle CEO Jeremy Allaire said machine-to-machine transactions are increasingly being settled in USDC, arguing that autonomous systems have effectively begun selecting their preferred form of digital money.

According to CoinMarketCap, Allaire said that “the machines have already chosen their money,” pointing to agent-to-agent transactions being settled overwhelmingly in USDC. The statement places the stablecoin at the center of an emerging discussion around how artificial intelligence agents could conduct payments without direct human involvement.

The claim focuses on transactions between autonomous software agents, rather than conventional consumer payments. As AI systems become capable of performing tasks independently, payments between those systems are increasingly being discussed as a potential use case for digital currencies and stablecoins.

USDC Positioned as Machine Payment Currency

Allaire’s comments specifically identify USDC as the dominant settlement asset in agent-to-agent transactions, according to the CoinMarketCap post.

USDC is a dollar-denominated stablecoin issued by Circle. Unlike cryptocurrencies whose market values can fluctuate significantly, stablecoins are designed to maintain a relatively stable value against an underlying asset, in this case the U.S. dollar.

That characteristic is particularly relevant to automated transactions, where software needs predictable settlement values when exchanging funds for services, data or other digital resources.

Allaire’s statement therefore frames USDC not simply as a cryptocurrency used by human customers, but as a payment instrument being adopted by autonomous software systems.

AI Agents Open a New Payments Use Case

The emergence of autonomous AI agents has created a new potential category of digital transactions. An agent can be designed to perform tasks, interact with other software and, in some implementations, initiate transactions based on predefined instructions.

Agent-to-agent payments would allow one system to compensate another without requiring a person to manually authorize every individual transaction. Such a model could be relevant to automated software services where transactions are frequent, small or triggered by machine-generated activity.

However, the CoinMarketCap post does not provide transaction volumes, a specific measurement period or independent data supporting the claim that agent-to-agent settlements are overwhelmingly conducted in USDC. Allaire’s statement is therefore best understood as a characterization of current activity rather than a comprehensive industry-wide measurement.

Circle’s Stablecoin Strategy

The comments also highlight the broader role that Circle is seeking for USDC as digital payments expand beyond traditional human-to-human transactions.

For stablecoins to function in autonomous payment systems, software must be able to identify counterparties, execute transfers and verify settlement while operating within applicable technical and financial constraints. The CoinMarketCap post does not provide details on which AI agents or platforms are involved in the transactions referenced by Allaire.

Allaire’s remark nonetheless identifies a specific direction for the stablecoin market: payments increasingly initiated and settled by software rather than directly by people. The extent to which that activity develops into a measurable segment of digital payments will depend on actual transaction data and adoption across AI platforms.

For now, the central claim from Circle’s CEO is that machines are already using USDC for agent-to-agent settlement, making autonomous payments an emerging use case to watch.
