Circle Internet Group (NYSE: CRCL) reported second-quarter FY26 revenue of $701 million, a 7% year-over-year increase, driven by growth in USDC circulation despite lower reserve return rates.

The company ended the quarter with $73.3 billion in USDC circulation, up 19% YoY. Average circulation reached an all-time high of $76.5 billion during the period, supporting robust transaction volumes even as broader digital asset market capitalization declined approximately 40% YoY.

Financial Performance

Total revenue and reserve income rose sequentially as average circulation hit record levels, though this was partially offset by a decline in the reserve return rate to 3.48%, down 66 basis points YoY reflecting lower SOFR rates. Other revenue increased 1.4 times YoY to $34 million, driven by blockchain partnerships, though it declined $8 million quarter-over-quarter due to moderating digital asset market conditions and a strategic pivot toward ARK development.

Revenue less distribution cost margin expanded 3 percentage points YoY to 41.2%, driven by a strategy to increase USDC held on Circle's platform, which grew 106% YoY to $12.4 billion. Adjusted operating expenses rose 23% YoY to $146 million, reflecting continued investment in product development, go-to-market infrastructure, and AI capabilities.

What the Numbers Show

USDC circulation growth decoupled from broader crypto market trends. While total digital asset market capitalization fell roughly 40% YoY, USDC circulation grew 19% over the same period. This divergence suggests increasing adoption of USDC in non-crypto markets, such as payments and settlement, rather than reliance on speculative trading activity or DeFi collateral demand.

Strategic Developments

Circle secured an OCC National Trust bank charter and a limited purpose trust charter from New York, establishing a federally supervised foundation for its digital asset services. The company also renewed its strategic partnership with Coinbase, ensuring USDC remains central across Coinbase's products.

Key operational milestones include:

• ARK mainnet launch scheduled for September 16, supported by a $242 million token presale.
• Partnerships with DTCC for tokenized securities and BlackRock for deploying BUIDL on ARK.
• Circle Payments Network (CPN) annualized total payment volume reached nearly $15 billion on a trailing 30-day basis at quarter-end, rising to $23 billion by July 31.

Guidance and Outlook

Circle raised its full-year other revenue guidance to $310–$330 million, up from $150–$170 million, largely due to anticipated ARK revenue. The company expects to recognize $180 million of ARK-related revenue in 2026. Full-year revenue less distribution cost margin guidance was increased to 41.7%–43.7%. Adjusted operating expense guidance of $570–$585 million remains unchanged, with management expecting results at the higher end of the range.

Circle Internet Group, Inc. (NYSE: CRCL) launched the public mainnet of Arc, an open Layer 1 blockchain designed for financial markets. The network integrates natively with Circle’s platform, including USDC, which has more than $74 billion in circulation.

Arc is secured by a founding validator cohort comprising institutions that run global finance. This group includes BlackRock, Visa, Mastercard, Standard Chartered, ICE, Galaxy, MoneyGram, SBI Group, Sumitomo Corporation, Worldpay, and The Depository Trust & Clearing Corporation (DTCC). More than 100 institutional and ecosystem builders are live on day one.

Design and Infrastructure

Arc distinguishes itself through six design choices aimed at onchain finance:

• Gas in dollars: Fees are paid in USDC, eliminating the need for a volatile native token.
• Sub-second finality: Deterministic, instant settlement ensures finality.
• Opt-in privacy: Confidential transactions and balances with view keys are in development.
• Issuers and interoperability: Supports USDC, EURC, and tokenized real-world assets, with Circle StableFX providing 24/7 cross-currency settlement.
• Agentic economic activity: Designed from genesis for AI agents as economic actors.
• Institutional security: Includes post-quantum signatures and deterministic consensus built to financial market standards.

Circle StableFX enables programmable FX trading with near-instant settlement. The Circle Payments Network is now integrated natively into Arc, moving money across borders for a fraction of a cent and settling in near real time. Active or onboarding local stablecoins include USDC, EURC, AUDD, AUDF, BRLA, CADD, CHFAU, EURAU, GBPA, JPYC, KRW1, MXNB, QCAD, SEKAU, TRYB, wARS, wBRL, wCLP, wCOP, wMXN, wPEN, and ZARU.

Agentic Economy Integration

Agents already perform economic tasks using Circle’s products, such as executing trades and managing payments. USDC accounts for 98.8% of agent-driven transaction volume. Since the Circle Agent Stack launched in May 2026, the majority of agent-to-agent payments settling over the x402 standard have settled in USDC.

Key tools for this ecosystem include:

• Circle Agent Stack: Provides policy-controlled Agent Wallets, Nanopayments via Circle Gateway, and an emerging Agent Marketplace.
• Arc Portal: Allows users to fund agent wallets, set spend limits, and delegate onchain tasks.
• AgentVM: Designed for agents to work with sensitive data in a protected environment while maintaining immutable records.

Institutional Participation

Beyond validators, more than 100 builders are live or exploring Arc. These include global banks like BNY, HSBC, Societe Generale, and State Street; asset managers such as Bitwise, Janus Henderson, and New York Life Investment Management; and payment firms including JCB, Thunes, and Global Payments.

Digital asset exchanges Binance, Coinbase, Kraken, and Robinhood provide access to Arc. Custody providers Anchorage, BitGo, Fireblocks, and Zodia Custody support institutional-grade security. Onchain trading protocols Aero, fomo, Uniswap, and 1inch anchor trading infrastructure, while Aave and Morpho support credit markets.

Markets and Assets

Aero, fomo, and Uniswap anchor Arc's day one trading infrastructure. Circle's USYC (a tokenized money market fund), BUIDL (a tokenized treasury fund tokenized by Securitize), private credit funds, and cirBTC give these markets high-quality, liquid, productive assets to trade, lend, and post as collateral.

Developer Ecosystem and Roadmap

Arc’s testnet processed more than 700 million transactions in under a year. The network is fully EVM-compatible, allowing existing Solidity contracts to work immediately. Circle released Arc Studio, an onchain coding agent, and Arc App Kits, a unified SDK for core fund flows.

The roadmap includes Network Sectors for privacy, payments targeting more than 100,000 transactions per second, and agent identity. Circle completed the genesis mint of the ARC token, creating an initial supply of 10 billion tokens. ARC serves as a coordination mechanism for security and governance, though network fees remain payable in USDC. A transition from Proof of Authority toward Proof of Stake is planned for 2027.

What the Numbers Show

The dominance of USDC in agent-driven activity highlights a concentration risk and dependency for the agentic economy. With USDC accounting for 98.8% of agent-driven transaction volume, the success of Arc’s “agentic” value proposition is tightly coupled with the continued adoption and regulatory stability of Circle’s specific stablecoin rather than a diverse multi-token ecosystem.
