Circle’s $222 million presale of ARC—the native token for its planned Arc blockchain—has reframed how investors value the USDC issuer and sharpened questions about the future of one of crypto’s most profitable alliances, its partnership with Coinbase. The transaction, announced on May 11 and led by a16z Crypto, set a $3 billion fully diluted valuation for Arc and anchors Circle’s push to make AI-driven commerce and on-chain finance a core part of its business alongside stablecoin issuance.

Market Impact

The presale coincided with first-quarter results that underscored Circle’s scale in the stablecoin economy. The company reported $694 million in total revenue and reserve income, up 20% year over year. USDC in circulation climbed 28% to $77 billion, and on-chain transaction volume reached $21.5 trillion, a 263% increase from the prior year. These figures reflect the role of tokenized dollars as core infrastructure for trading, payments, and settlement—and they illustrate why Circle is seeking a broader growth narrative that is not bound to interest-rate cycles.

Historically, Circle’s model has been tied to income earned on the safe assets backing USDC. That model is lucrative when rates are high but leaves open questions about earnings durability as interest income normalizes. Arc is presented as Circle’s answer: a network-level platform that expands the company’s addressable market and creates new revenue touchpoints across payments, tokenized assets, foreign exchange, capital markets, and AI-driven transactions.

AI Integration

Arc is positioned by Circle as an “economic operating system” for the internet—a shared base where stablecoins and financial applications can interact programmatically. The chain is expected to be EVM-compatible and to feature stablecoin-native fees, deterministic sub-second finality, and configurable privacy to meet institutional demands for auditability without revealing every transaction detail on public ledgers.

Chief Executive Jeremy Allaire framed the quarter around the convergence of AI platforms and on-chain money, saying the company is building “trusted infrastructure for AI-native economic activity and a more programmable internet financial system.” That message links Arc with Circle’s Agent Stack, a toolkit meant to enable AI agents to transact with digital dollars. The strategy puts Circle squarely on terrain where Coinbase is already active, with the US exchange positioning its Base network and developer stack as a settlement layer for stablecoins, consumer payments, and agentic transactions.

Technology Use Case

Arc gives Circle its own venue to host the flows USDC already enables across more than 30 blockchains and a wide array of exchanges, wallets, fintech platforms, and institutional systems. In Arc’s architecture, USDC remains the transactional asset while the ARC token is intended to coordinate validators, builders, liquidity providers, exchanges, institutions, and users. If the network gains traction, the metrics that investors watch will broaden beyond USDC supply and reserve income to include on-chain activity, developer adoption, institutional participation, validator engagement, and the extent to which Circle captures value from the infrastructure around USDC.

Circle Payments Network (CPN) and Managed Payments fit into the same blueprint. According to a note shared with CryptoSlate, Clear Street said CPN reached $8.3 billion in annualized total payment volume and approached $10 billion by May 7, with 136 financial institutions enrolled. Managed Payments is intended to reduce friction for banks and payment service providers by handling licensing, liquidity, custody, and compliance burdens. Together with Arc and Agent Stack, these products support Circle’s attempt to be the platform where digital dollars move, settle, and integrate with software, including AI agents.

Industry Response

The investor roster behind the ARC presale highlights how widely Circle’s pitch now resonates. a16z Crypto led with a $75 million commitment, joined by BlackRock, Apollo Funds, Intercontinental Exchange, SBI Group, Janus Henderson Investors, Standard Chartered Ventures, General Catalyst, IDG Capital, Haun Ventures, and Bullish. Clear Street analysts echoed Circle’s message to public markets, writing that the company is “no longer a pure crypto play” and has assembled a Layer 1 network, application layer, and partner ecosystem to serve as critical infrastructure. The firm raised its price target on the stock from $152 to $157, citing Arc, Agent Stack, Circle Payments Network, and regulatory momentum as potential drivers.

Coinbase’s Position

The expansion also complicates the long-standing Circle–Coinbase relationship. Coinbase already describes itself as the distribution engine for USDC, reporting that more than 25% of total USDC in circulation—about $19 billion on average—was held across its products in the first quarter. Coinbase said Base processed 62% of global on-chain stablecoin transaction volume during the period, more than all other chains combined.

Coinbase further reported that more than 90% of on-chain agentic stablecoin transaction volume occurred on Base, positioning the company as a leading platform for agentic commerce. Its x402 protocol processed more than 100 million payments, with over 99% completed in USDC. That stack—USDC as a programmable dollar, Base as a low-cost settlement layer, plus Coinbase Developer Platform, AgentKit, and x402—directly overlaps with the direction in which Circle is steering Arc, Agent Stack, and CPN.

A Partnership Under Strain

For years, Circle issued USDC while Coinbase distributed it across exchange, wallet, and institutional channels—a clean division that helped the stablecoin scale and generated meaningful revenue for both sides. Arc introduces a different incentive structure. As investor Omar Kanji of Dragonfly asked in a public post, how long can the “marriage” stay clean if Circle must prove to public-market investors that it can own more customers, flows, and infrastructure directly?

The overlap is already visible in adjacent products. Coinbase offers cbBTC, a wrapped BTC product used across DeFi, while Circle is preparing cirBTC to integrate with Arc and Circle Mint. While none of this signals an immediate break, it shows the companies moving into similar lanes as they pursue the same flows in tokenization, payments, and stablecoins.

AI Payments Raise the Stakes

The competitive implications are clearest in agentic commerce. AI agents are expected to handle tasks like purchasing data, paying for software, settling invoices, managing subscriptions, and executing business processes. Such activity requires programmable money, low-cost settlement, and infrastructure that can authorize spending without continuous human oversight—conditions that stablecoins and purpose-built networks are designed to meet.

Coinbase is claiming early leadership with Base’s share of agentic stablecoin volume and rapid growth in x402 payments. Circle, for its part, has aligned Arc and Agent Stack with the same opportunity, with Allaire presenting AI platforms and on-chain money as components of a new internet stack. Tom Wan, head of data at Entropy Research, summarized the trajectory: the companies’ business lines are converging across blockchain, tokenization, payments, and stablecoins; a formal split is unlikely given ongoing mutual benefits, but the overlap is set to create more friction over time.

For now, both firms remain commercially aligned around USDC’s growth. Yet Arc gives Circle a venue and a token to organize the economic rules of a network that could sit at the center of AI-native transactions. That prospect—alongside Coinbase’s existing footprint with Base, AgentKit, and x402—sets up a new scoreboard for a partnership that helped define stablecoins’ role in digital markets and may now shape how AI interacts with on-chain money.
