Brian Armstrong: AI agents will soon out-transact human users

Armstrong envisions a future defined by "Agentic Finance," or AiFi, where software agents autonomously pay for data, computing power, and other digital services without human oversight. Traditional banking systems, designed for human or corporate identity, cannot accommodate the high-frequency, programmable needs of these entities. By leveraging stablecoins like USDC and low-cost settlement layers such as Base, Armstrong believes machines can execute global, instant payments that power a machine-to-machine marketplace.

Coinbase is aggressively building toward this shift, launching tools like the Agentic.market and x402 protocol support to facilitate machine commerce. These systems allow websites and APIs to request micro-payments during internet interactions, which wallets then sign and settle. While Coinbase reports that agents already utilize these tools to procure resources, the broader economic impact remains speculative. Independent researchers have recently flagged security vulnerabilities and concentrated transaction patterns in x402-based systems, suggesting the technology is still in its infancy. Meanwhile, regulators, including the Bank of England, are beginning to scrutinize the risks posed by autonomous financial actors that operate outside existing oversight frameworks.
