Bernstein: Circle, Coinbase Top Picks for Stablecoin AI Growth

• Bernstein identifies Circle and Coinbase as the primary investment proxies for capturing the growth of the stablecoin market.
• The rise of agentic machine payments, where software and AI autonomously conduct transactions, is highlighted as a major future growth driver.
• USDC has reached all-time highs in supply and volume, currently leading the industry in transaction volume despite being second in total market capitalization.

The Shift Toward Autonomous Machine Payments

In a recent report led by analyst Gautam Chhugani, Bernstein emphasized that stablecoins are uniquely positioned to power the "agentic machine economy." This emerging sector involves transactions that are initiated, authorized, and settled entirely by autonomous software or devices without human intervention. Unlike traditional automated billing, these payments are programmatic, allowing AI agents to negotiate prices and settle trades in real-time.

Several major players are already building the necessary infrastructure for this transition:

• Coinbase has developed the x402 agent payments protocol to integrate financial transfers into the internet's HTTP layer.
• Circle has launched specialized nano-payments infrastructure tailored for autonomous agents.
• Stripe recently introduced its Machine Payments Protocol (MPP) on the Tempo blockchain following its acquisitions of Bridge and Privy.

Technical Advantages of Stablecoin Rails

Bernstein analysts argue that stablecoins are superior to traditional banking systems for machine-led commerce because they are programmable and borderless. By embedding logic such as escrow or revenue splitting directly into the currency, agents can execute complex financial tasks without waiting for manual bank confirmations or navigating the SWIFT network.

Furthermore, high-throughput blockchains enable microtransactions that would be economically unfeasible in legacy systems. Coinbase’s x402 protocol has already processed roughly $25 million in volume over the last 30 days, while Stripe’s MPP recorded $5,000 during its debut week. While these figures are nascent, they demonstrate the functional viability of the technology.

Market Outlook and USDC Performance

Regardless of the speed at which AI payments scale, Bernstein maintains a bullish outlook on the stablecoin sector due to its "hyper-growth" in traditional finance applications. This includes cross-border business settlements, consumer remittances, and new neo-banking services.

USDC is currently at the forefront of this expansion. The stablecoin's supply and transaction volumes are hitting record levels, driven by a new wave of fintech companies building exclusively on stablecoin rails. The analysts conclude that the investment case for stablecoins is now diverging from the broader, more volatile crypto market, establishing the asset class as a stand-alone pillar of modern financial services.
