Circle prices Arc at $3 billion by selling 7.4% of its token supply for $222 million
Arc's mainnet went live on September 16 with USDC as its gas token and BlackRock, Visa and Mastercard among the validators, and Circle's product chief says the growth has to come from AI agents; shifting Ethereum's existing users across would not grow the market.
The Investor · Invest desk
What happened
- Circle launched Arc, a Layer-1 blockchain built for stablecoins and AI agents, with USDC as the native gas token instead of a separate fee currency and sub-second deterministic finality.
- The ARC token has a fixed initial supply of 10 billion, and a private presale of 740 million tokens at $0.30 each raised $222 million, pricing the project at roughly $3 billion post-sale.
- BlackRock, Visa and Mastercard are among the institutional validators supporting the network from launch.
Why it matters
- Who has to decide decision Circle says it will not build the applications itself, so whether Arc carries traffic is a decision now sitting with third-party developers and enterprises.
- What it limits constraint The cheapest early volume available to any new chain is activity that already runs elsewhere, and Circle's stated test for growth excludes exactly that.
- Who's exposed exposure Arc collects its fees in USDC, so a presale buyer's return depends on what the ARC token itself reprices to.
- What it sets up precedent A validator set that includes an asset manager and two card networks sets the institutional bar competing stablecoin chains will be asked to match.

Circle aims USDC at about 40 emerging markets from a 25% share of stablecoinsConfirmed3 publishers
740 million tokens out of a fixed initial supply of 10 billion is 7.4% of the stock [3][15]. The $222 million Circle raised therefore puts a 30-cent mark on the 9.26 billion tokens still unsold, about $2.78 billion of notional [16]. The $3 billion headline number is that private clearing price times the full supply [17].
Gas is the commercially important part of the design. Arc charges gas in USDC and did not mint a separate fee currency [2], and settlement is sub-second and deterministic through what Circle calls its Malachite consensus engine [7]. Crypto Briefing describes the result as a built-in demand loop, since every agent transaction generates USDC gas fees and reinforces USDC's utility [18]. Circle runs the second-largest stablecoin by market capitalisation [8].
Nikhil Chandhok, Circle's chief product and technology officer [11], said at the September 16 mainnet launch: "If all we did was we took activity from Ethereum and moved it to ARC we didn't really grow the market." [10] His argument is that Ethereum already serves its existing user base. What it does not serve is agents that need to transact autonomously, build reputations and settle in stable value at software speed [13].
The first version of this has agent transactions arriving in volume. The primitives have had a run: the Agent Stack's provenance proofs, reputation systems and nanopayments shipped in May 2026, roughly seven months after the public testnet [6][14]. The second version, and the one the launch evidence supports better, has the early volume coming from the validators themselves. BlackRock, Visa and Mastercard were validating at launch [4], and settlement flows of that kind already clear somewhere else today. A third has neither arriving in size, leaving Arc as a venue for USDC that Circle routes itself.
On what has been published, institutional stablecoin settlement is the market Arc is underwritten against. The validator names exist on day one; agent demand is a forecast. Arc's core thesis is explicitly that the next wave of onchain activity comes from machines rather than humans trading on decentralised exchanges [5]. What would change my mind is a count of agent-initiated transactions reported separately from the validators' own settlement volume. Crypto Briefing applied a similar test to the token, writing that buyers at $0.30 will want to see "real network activity, not just validator logos" [19].
What to watch
- A secondary market print for ARC against the 30-cent presale price, and any unlock schedule for the 9.26 billion tokens Circle did not sell.
- Whether BlackRock, Visa or Mastercard move settlement volume across Arc, or only run validators on it.
- Any sign Circle begins shipping agent applications itself, against Chandhok's infrastructure-provider positioning.

Ranked by verification strength, evidence, and original report placement.
- [1]
Circle launched Arc, a Layer-1 blockchain built from the ground up for stablecoins and AI agents.
- [2]
Arc uses USDC as its native gas token rather than minting a separate fee currency, so every transaction is denominated in a dollar-pegged stablecoin.
- [3]
The ARC network token has a fixed initial supply of 10 billion, and Circle completed a $222 million private presale of 740 million tokens at $0.30 each, pricing the project at roughly $3 billion post-sale.
- [4]
BlackRock, Visa and Mastercard are among the institutional validators supporting the Arc network at launch.
- [5]
Arc's core thesis is that the next wave of onchain economic activity will come from AI agents transacting at machine speed, verifying their own work and building reputations onchain, not from humans swapping tokens on decentralised exchanges.
- [6]
Circle's Agent Stack, which gives AI agents primitives including provenance proofs, reputation systems and nanopayments, rolled out in May 2026 after a public testnet went live in October 2025.
- [7]
Arc offers sub-second deterministic finality through what Circle calls its Malachite consensus engine, with transactions settling in under a second and no probabilistic ambiguity about confirmation.
- [8]
Circle controls the world's second-largest stablecoin by market capitalisation.
- [9]
Chandhok positioned Circle as an infrastructure provider that is not developing applications directly; third-party developers and enterprises are expected to build the AI agent applications on top of the Agent Stack.
- [10]
Nikhil Chandhok said during the Arc mainnet launch on September 16: "If all we did was we took activity from Ethereum and moved it to ARC we didn't really grow the market."
- [11]
Nikhil Chandhok is Circle's Chief Product and Technology Officer.
- [12]
Because gas on Arc is denominated in USDC, network transaction fees are not paid in the ARC token.
- [13]
According to Chandhok, Ethereum already serves its existing user base well enough, and what it does not serve is the emerging category of AI agents that need to transact autonomously, build reputations and settle payments in stable value at software rather than human speed.
- [14]
About seven months separated Arc's October 2025 public testnet and the May 2026 Agent Stack rollout.
- [15]
The 740 million tokens sold in the presale are 7.4% of Arc's fixed initial supply of 10 billion.
- [16]
The 9.26 billion ARC tokens not sold in the presale carry about $2.78 billion of notional value at the same $0.30 price.
- [17]
The roughly $3 billion post-sale price is the $0.30 presale price applied to the entire 10 billion initial supply.
- [18]
Crypto Briefing writes that making USDC the native gas asset creates a built-in demand loop, because every AI agent transaction on Arc generates USDC gas fees, which reinforces USDC's utility and potentially drives more USDC adoption.
- [19]
Crypto Briefing writes that the $222 million presale at a $3 billion valuation sets a high bar, and that early token buyers at $0.30 "are going to want to see real network activity, not just validator logos."
