Circle minted ten billion tokens and called them a digital commodity, a day after the Senate declined to define one

What happened

Circle Internet Group announced the public mainnet launch of Arc on 16 September 2026, describing it as an open layer one blockchain purpose-built for financial markets, real-time money movement and agentic economic activity. The release says Arc goes live with more than 100 applications and more than 100 institutional and ecosystem builders, and it sets out six design choices. The first is the one that defines the network: 'Gas in dollars. Fees are paid in USDC, with no volatile native token required.' The others are sub-second deterministic finality, opt-in confidential transactions with view keys described as in development for network-wide release, a home for USDC, EURC and tokenized real-world assets with Circle StableFX settling across currencies, a design for artificial intelligence agents as economic actors, and post-quantum signature support. Circle then minted a native token anyway. Under the heading The Road Ahead, the release says the company 'completed the genesis mint of ARC token this week in the U.S., creating the full initial supply of 10 billion tokens', which it says makes Circle 'the first publicly traded company to mint a network token for a new layer-one blockchain'. The description of what the token is reads: 'ARC is designed to serve as a digital commodity intended to act as the native coordination mechanism for security, utility, and governance on Arc, with network fees remaining payable in USDC.' The next sentence is the qualifier: 'This initial mint is not a commitment to publicly launch ARC, but an important technical milestone in the Arc roadmap as the network explores a future transition from Proof of Authority toward Proof of Stake in 2027.' The validator cohort is eleven institutions alongside Circle: BlackRock, the Depository Trust and Clearing Corporation, Galaxy, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, Visa, and Worldpay, now part of Global Payments. The release says the rollout from that cohort will be phased, and that these firms 'are not simply connecting to Arc; they will participate in the operation of the network itself, securing a public blockchain built to meet institutional needs'. Michael Blaugrund, vice president for strategic initiatives at ICE, is quoted saying that as a founding validator ICE 'is applying our experience securing critical market infrastructure in support of Arc itself'. Robbie Mitchnick, global head of digital assets at BlackRock, is quoted more carefully: 'Purpose-built blockchains can help accelerate adoption of digital asset use cases, and Arc appears clearly well positioned to serve stablecoin and payment use cases at scale.' The wider list runs to global banks including BNY, HSBC, Societe Generale and State Street; asset managers and real-world asset issuers including Bitwise, BlackRock, Janus Henderson, New York Life Investment Management with Centrifuge, Maple and ProShares; exchanges including Binance, Coinbase, Kraken and OKX; custodians including Anchorage, BitGo, Copper and Fireblocks; and lending markets anchored by Aave and Morpho, with Stani Kulechov of Aave Labs quoted announcing 'a new Aave V4 market on Arc'. Aero, fomo and Uniswap are named as the day one trading infrastructure, and Circle's USYC, BlackRock's BUIDL as tokenized by Securitize, private credit funds and cirBTC as the collateral. Two figures in the release carry no source and are Circle's own. It says USDC 'accounts for 98.8% of agent-driven transaction volume', without giving the population that percentage is taken from, and that the Arc testnet 'processed more than 700 million transactions in under a year'. USDC in circulation is given as more than $74bn, which Circle's transparency page puts at $74.2bn as of 14 September. The disclaimer at the foot of the release says Arc was launched by Arc Network Services LLC and is operated by a permissioned validator set, that the company 'provides software services only and does not offer regulated financial or advisory services', and that Arc 'has not been reviewed or approved by the New York State Department of Financial Services or any other regulatory authority'.

Why it matters

The phrase to stop on is digital commodity. It is not marketing language; it is the operative category in H.R. 3633, whose own long title is a system of regulation for the offer and sale of digital commodities divided between the Securities and Exchange Commission and the Commodity Futures Trading Commission. The Senate declined to take that bill up on Monday afternoon. On Tuesday morning a New York Stock Exchange-listed company said it had minted ten billion units of something it describes in those words. With no statute, the term has no legal content in the United States beyond what the agencies make of it, and the first mover in filling that vacuum is an issuer describing its own asset rather than a regulator describing a class of them. The qualifier is the interesting half. A genesis mint that is 'not a commitment to publicly launch' creates the entire supply of an asset while declining to distribute or offer it, which keeps the company clear of the questions an offering would raise and leaves the supply sitting with the minter. Meanwhile the network runs on Proof of Authority, so the token secures nothing yet; the release says a move towards Proof of Stake is being explored for 2027. So Arc today is a chain whose fees are paid in a regulated dollar stablecoin, whose blocks are produced by a named and permissioned set of large financial institutions, and whose native token exists in full but does nothing. That is an unusual object, and the ordering of it matters: the supply was fixed before the mechanism that gives it a purpose. The validator list is the part that changes the picture of who runs public infrastructure. A depository and clearing corporation, two card networks, an exchange operator, a global bank and a money transmitter producing blocks is not the same as those firms using a chain, and it makes the set of people who can censor or reorder transactions on Arc identical to a subset of the institutions that already clear and settle in the existing system. Circle frames this as institutional trust meeting open innovation, and cites the GENIUS Act as the regulatory clarity that lets banks use a public chain. The other reading is that the permissioned validator set is what makes it usable by them, in which case the openness is at the application layer and the settlement layer has the same gatekeepers as before, with a new operator in the middle whose disclaimer says it provides software only. And gas in USDC ties the economics of the network to the issuer's balance sheet rather than to a floating token. Every transaction on Arc is demand for a liability of Circle's, which converts throughput into stablecoin float and therefore into reserve income, without exposing users to the fee volatility that a native gas token brings. It is a coherent design and it is also a vertical one: the network, the unit of account, the settlement asset, the cross-currency layer and the payments network are all products of the same company, and the tokenized money market fund posted as collateral on it is too.

What is not settled

What ARC is for, legally and economically, is unresolved by design. The release says the mint is not a commitment to launch and that Proof of Stake is being explored rather than scheduled. Nothing published says who holds the ten billion, whether any will ever be distributed, on what terms, or what happens to the holding if the transition does not happen. A fixed supply with no circulation and no function is not yet a market, and the questions a reader would want answered, allocation, lockups, and whether the company or an affiliate holds it, are not in the document. Whether an agency accepts the characterisation is a separate matter. Calling an asset a digital commodity does not make it one, and with the bill that would have allocated jurisdiction stalled, the SEC and the CFTC will each reach their own view about a token minted by a listed issuer to coordinate security and governance on a chain it launched. The disclaimer that Arc has not been reviewed or approved by any regulatory authority is accurate and is not a safe harbour. The validator arrangement is announced rather than documented. The release says the rollout from the founding cohort is phased and does not say how many of the eleven are producing blocks today, what the governance perimeter it refers to actually is, how a validator is added or removed, or what obligations Arc Network Services LLC owes to users. For firms subject to operational resilience rules, participating in the operation of a public network is a supervisory question, and none of the eleven has published anything on how it is treated. The privacy and scale claims are forward-looking on the page itself. Opt-in confidential transactions are described as in development for network-wide release, and the payment sector targeting more than 100,000 transactions a second sits on a roadmap alongside a privacy sector and an agent sector. The testnet figure of more than 700 million transactions is Circle's and unaudited, and there is no independent measurement of what mainnet does. Finally, the agent statistic, 98.8 per cent of agent-driven transaction volume, is the kind of number that will be quoted widely and is unsourced where it is published.
