Circle Raises $222M Arc Token Presale at $3B Valuation, Unveils Agent Stack for AI-Driven USDC Payments

USDC News

Circle has rolled out Agent Stack, a developer suite engineered to let autonomous AI agents hold balances, route payments, and contract other software services using USDC. The launch bundles agent-specific wallets, a command-line interface, an agent marketplace, and a nanopayments protocol capable of pushing transfers as small as $0.000001 with zero gas friction. The stack is purpose-built for machine-to-machine commerce that conventional banking rails cannot serve. CEO Jeremy Allaire framed AI agents themselves as the customer base, not just human developers, signaling a structural pivot in how stablecoin infrastructure is monetized across the emerging agentic economy on blockchain networks.

Circle simultaneously closed a $222 million token presale for its Arc network, pricing the layer-1 at a $3 billion fully diluted valuation. Andreessen Horowitz led with a $75 million commitment, joined by BlackRock, Apollo Funds, ARK Invest, Intercontinental Exchange, Standard Chartered Ventures, SBI Group, and Janus Henderson. The round makes Circle the first publicly listed company to conduct a token presale, and the buyer roster reads as a who's-who of institutional capital looking to position around tokenized finance. ARC tokens were sold at $0.30 each under a Regulation D-style private placement exempt from registration under the US Securities Act of 1933.

The Arc whitepaper, published the same day, describes ARC as a native coordination asset supporting governance, security, and validator operations across the network. Total supply is fixed at 10 billion tokens: 60% routes to ecosystem participants who build and contribute, Circle retains 25% to operate validator infrastructure and earn staking income, and the remaining 15% sits in a long-term reserve. Arc will run on a hybrid model that begins with permissioned validators and transitions toward a proof-of-stake consensus mechanism. The chain is EVM-compatible, offers sub-second finality, and will ship a post-quantum signature scheme at mainnet.

Quarterly results reinforced the scale of the franchise underwriting the Arc bet. USDC in circulation climbed 28% year over year to $77 billion, while on-chain transaction volume surged 263% to $21.5 trillion. Total revenue and reserve income reached $694 million, up 20%, and adjusted EBITDA expanded 24% to $151 million. Net income from continuing operations slipped 15% to $55 million as operating expenses jumped 76%, weighed down by post-IPO stock-based compensation and related payroll taxes. The Circle Payments Network ran at an $8.3 billion annualized transaction pace at quarter-end.

Markets responded forcefully to the dual announcement, with Circle shares surging more than 15% intraday and extending gains beyond 50% over the trailing month. Analysts have begun reframing the equity story, arguing that Arc represents a second growth engine that diversifies the issuer away from reserve-yield dependency. Today USDC settles primarily across Ethereum and Solana and leans heavily on distribution partner Coinbase, a structural exposure Allaire has openly signaled he wants to reduce. Owning more of the rail stack would let Circle internalize fees, validator economics, and tokenization flows currently captured by host chains and intermediaries on every exchange integration.

In an unrelated security incident, a whitehat operator returned roughly $190,000 to Arbitrum-based dark pool protocol Renegade after exploiting a faulty deployment contract tied to its V1 pool. Blockaid initially flagged a $209,000 drain involving 27 ERC-20 tokens, including $84,370 in USDC, $27,885 in wrapped Bitcoin, and $23,950 in wrapped Ether. The Renegade team posted an on-chain message offering a 10% bounty in exchange for the rest, and the hacker complied within 45 minutes, citing a desire to protect DeFi users. The team attributed the bug to missing ownership assignment and a faulty April 2025 migration.

USDC's spot dynamics remain anchored to the dollar peg, so directional technicals carry less weight than for volatile assets; current readings for spot, RSI, MACD, and 24-hour range are unavailable. The meaningful signal sits in flows and circulation, where supply expanding 28% to $77 billion and transaction throughput surging 263% to $21.5 trillion mark a clear bullish demand backdrop. Key levels to watch are the $80 billion circulation threshold and Arc mainnet adoption. The bullish thesis is invalidated by sustained net redemptions, a peg deviation beyond 50 basis points, or stalled institutional onboarding around the planned summer Arc launch.
