Circle (issuer of USDC) just closed a $222 million funding round for its Arc stablecoin infrastructure project, valuing it at $3 billion.
The round landed roughly 45 minutes ago and is already generating strong discussion as another major institutional signal for stablecoin/RWA growth.
The raise was specifically a presale of the ARC token, the native token of Circle’s new Arc public blockchain.
Andreessen Horowitz led the round with a $75 million investment. Other participating investors include Apollo Funds, ARK Invest, BlackRock, Bullish, General Catalyst, Haun Ventures, Intercontinental Exchange, IDG Capital, Janus Henderson Investors, Marshall Wace, SBI Group, and Standard Chartered Ventures.
What Is Arc?
Institutional finance is the primary target market for Arc, which Circle has built as a public blockchain.
CEO Jeremy Allaire has described it as an operating system for economic activity, one that goes well beyond stablecoins and payments alone.
In an exclusive interview with CNBC, Allaire framed it in expansive terms: “Blockchain infrastructure is becoming as important as mobile operating systems or cloud platforms.
We want to build an operating system that has many, many stakeholders in it major companies who are running the infrastructure with us and who ultimately help to govern it.”
Alongside the funding announcement, Circle published the ARC Token whitepaper today, which outlines how the native token could support governance, security, and network operations across the Arc ecosystem.
A Broader Platform Play
This raise signals that Circle is moving well beyond its core USDC business. On the developer side, Circle is building what it calls “The Agent Stack” a suite of new products including a Circle CLI (command line interface), Agent Wallets, and an Agent Marketplace.
These tools are designed to let developers and merchants create, fund, and monetize agent-driven activity in USDC across multiple blockchains and payment protocols.
Allaire put it plainly: “We’re becoming a broader internet platform company.
We’re entering the operating system business and we’re doing it by building this multi-stakeholder distributed model with a token, with a distributed network.”
Strong Financials as a Backdrop
The raise comes on the back of a strong Q1 2026 for Circle. USDC in circulation hit $77 billion at quarter end up 28% year-over-year while onchain transaction volume reached $21.5 trillion, a 263% surge.
Total revenue and reserve income came in at $694 million for the quarter, up 20%, and Adjusted EBITDA grew 24% to $151 million.
Circle also reported continued expansion of its Circle Payments Network (CPN), with $8.3 billion in annualized transaction volume based on trailing 30-day activity as of March 31, 2026.
In April, the company added Managed Payments, a product that lets financial institutions launch stablecoin payments without having to directly manage digital assets.
Why It Matters
The investor lineup here reads like a who’s who of both traditional finance and crypto-native capital. BlackRock, Apollo, ICE, Standard Chartered, and Janus Henderson sit alongside a16z, ARK, and Haun Ventures. That mix is telling.
It reflects a growing consensus that stablecoin infrastructure is no longer a niche bet; it is rapidly becoming core financial plumbing.
Arc’s positioning as a public blockchain purpose-built for institutional use, paired with a token designed for governance and network coordination, puts Circle in direct competition with both general-purpose blockchains and permissioned enterprise chains.
The $3 billion fully diluted valuation on this presale alone suggests the market is taking that ambition seriously.
