AI agent economy will outpace the human economy, Coinbase CEO Brian Armstrong says

Coinbase CEO Brian Armstrong has predicted that AI-powered agents will ultimately generate more commercial activity than the entire human economy, pointing to a wave of machine-to-machine transactions already reshaping how digital services are bought and sold.

In a recent statement, the Coinbase chief executive argued that companies including Amazon, Google, and Circle are accelerating the development of infrastructure that allows AI agents to independently buy services, process payments, and manage digital interactions without relying on conventional banking systems.

The remarks come as the Ai agent economy gains momentum through blockchain-based payment networks, stablecoins, and automated cloud infrastructure. Coinbase, through its Base blockchain ecosystem and related AI-focused payment tools, is positioning itself at the center of what Armstrong describes as the next major phase of internet commerce.

Ai agent economy gains support from major technology firms

The Ai agent economy is increasingly attracting support from some of the world’s largest technology companies as businesses race to establish infrastructure capable of supporting autonomous machine payments.

According to Armstrong, the shift is no longer a theoretical concept but an active transformation already underway across the technology sector.

“The volume of commerce between autonomous AI agents will surpass the scale of the human economy,” — Brian Armstrong.

Armstrong explained that AI systems do not require traditional financial tools such as passports, bank accounts, or payment cards. Instead, they rely on blockchain networks and programmable digital assets to conduct transactions automatically.

Coinbase has emerged as a key player within the Ai agent economy through its Ethereum layer-2 network Base. The company has also launched Agentic.market, a marketplace designed to help AI agents discover services and transact with one another, alongside the x402 open payment protocol.

According to Armstrong’s earlier comments referenced in the report, cryptocurrency remains “the only viable form of money for machines,” largely because blockchain systems allow automated payments to occur without centralized financial intermediaries.

The expansion of these systems suggests that the Ai agent economy is evolving beyond experimentation into an increasingly functional commercial ecosystem.

Ai agent economy powered by stablecoins and automated payments

The rapid growth of the Ai agent economy is being fueled by growing adoption of blockchain payment standards such as Coinbase’s x402 protocol.

Amazon Web Services has reportedly integrated automated billing tools that enable third-party AI agents to independently purchase additional cloud computing capacity using microtransactions. This allows AI-driven systems to scale operations dynamically without requiring manual human approval for each transaction.

Meanwhile, Circle Internet Group reportedly recorded more than $100 million in transaction volume within four months through its Agent Stack platform, which focuses on AI-driven financial operations.

“Corporate integration of the x402 standard is already advancing on all fronts,” — U.Today report.

Competitors are also moving aggressively into the sector. Google Cloud and Solana Labs introduced Pay.sh, a marketplace where AI agents can independently discover, test, and purchase APIs using stablecoins without requiring user registrations.

Industry data cited in the report highlights the accelerating scale of the Ai agent economy. The x402 protocol has reportedly processed more than 169 million transactions worth over $50 million.

Coinbase’s Base network currently accounts for approximately 82.1% of all AI agent payment activity, supporting around 250,000 daily active AI agents while recording infrastructure growth of 400% year-over-year.

The report also noted that machine-driven transactions remain heavily concentrated in stablecoins, with approximately 99.8% of payments conducted using USDC.

Ai agent economy could reshape internet business models

The rise of the Ai agent economy is beginning to challenge traditional models of online commerce built around direct human participation.

Rather than relying solely on business-to-business or business-to-consumer interactions, the emerging system enables AI programs to autonomously purchase services from other AI systems in real time. These transactions can involve fractions of a cent and occur thousands of times per second.

“Replacing traditional B2B and B2C models is an economy where one AI script purchases a microservice from another AI script,” — U.Today report.

Supporters of the Ai agent economy argue that this model could dramatically increase efficiency across cloud computing, software distribution, digital advertising, and financial services. Critics, however, continue to raise concerns around security, accountability, and regulatory oversight as autonomous systems gain greater control over financial decision-making.

Coinbase’s growing involvement suggests the company sees machine-to-machine payments as a major long-term opportunity tied to both blockchain infrastructure and stablecoin adoption.
