Circle, the company that issues the USDC stablecoin, raised $222 million in a presale of its ARC token to fund its own blockchain, reported May 11, 2026. The raise put a $3 billion fully diluted valuation on the project, with a16z crypto leading at $75 million and a backer list that reads like a Wall Street guest book: BlackRock, Apollo, Intercontinental Exchange, Standard Chartered Ventures, ARK Invest, and others. The chain is called Arc. The point of it is the part most readers will miss: Circle wants to keep the settlement fees that today run through Ethereum.
What Circle actually raised, and for what
The $222 million came from selling ARC tokens before the network is live. That is the first thing to hold onto. A presale token is not something you can trade on an exchange today, and the $3 billion valuation is a fully diluted figure, a paper number that prices the whole future supply, not cash in the door.
The money funds Arc, which Circle describes as a public Layer 1 blockchain built for institutional finance. A Layer 1 is a base blockchain in its own right, the way Ethereum or Solana are, rather than a layer that settles on top of one. Arc's distinguishing feature is the fee token. Most chains charge gas in their own volatile native coin, ether on Ethereum. Arc charges in USDC, the dollar-pegged stablecoin Circle already issues. The network is pitched with sub-second finality, opt-in privacy controls aimed at compliance, and full compatibility with the EVM, the Ethereum software standard that lets existing apps port over with little rework. Circle says the public testnet went live in October 2025.
Why this matters
Every time a stablecoin moves on Ethereum, someone pays a fee in ether, and that fee accrues to Ethereum, not to the company that issued the coin. USDC is one of the largest stablecoins, and a large share of its transaction volume settles on Ethereum. Building Arc is Circle's move to capture that flow. Put the settlement on a chain Circle controls, price the gas in Circle's own dollar token, and the fees that today leak out to the Ethereum fee market stay closer to home.
The backer list is the tell. a16z crypto's $75 million is the anchor, but the names behind it, BlackRock, Apollo, the exchange group that owns the NYSE, point at who Arc is for. This is not a chain chasing retail traders. It is institutional plumbing, built so the firms that already move money for a living can settle it on rails that look like the regulated systems they know.
What it does not tell you
The valuation is the easiest figure to over-read. $3 billion fully diluted is not money raised and not a market price; it is the headline number from a private sale of a token that does not yet trade. ARC has no live market, so there is no price action to read and no liquidity to lean on. Anyone framing this as a $3 billion company is reading the paper figure, not a tape.
Beyond that, several specifics rest on the reporting and on Circle's own framing rather than on a working network. Sub-second finality, opt-in privacy, and the EVM compatibility are described features of a chain still in testing, not measured results from a live mainnet. Reports differed on the exact backer roster, and the timeline to a public mainnet is the gap that matters most: a funded testnet is not a chain handling institutional settlement at scale.
What we are watching
The mainnet date and the first real settlement volume on it. A presale and a marquee cap table tell you who is betting; they do not tell you whether issuers and trading desks actually route USDC through Arc once it is live. The other thing to watch is the response from Ethereum's side, where the fees Circle is aiming at currently land. If Arc pulls even a slice of USDC settlement onto its own chain, the question stops being who funded it and becomes how much flow it can take.
