Coinbase CEO Brian Armstrong believes that artificial intelligence and cryptocurrency are not competing technologies. Instead, he argues that they will work together, with crypto becoming the financial infrastructure that powers the growing world of AI agents.
In a post on X on July 27, Armstrong predicted that autonomous AI agents could eventually carry out more daily transactions than all humans combined. He said these agents will need a way to buy data, software, computing power, and other digital services without requiring constant human approval, and that traditional banking systems are not designed for that type of machine-to-machine economy.
According to Armstrong, blockchain networks and stablecoins provide the ideal solution because they allow fast, global, programmable payments that can be executed automatically. He described the combination of AI and crypto as “Agentic Finance” (AiFi), where AI provides intelligence and crypto provides money and settlement.
Armstrong’s comments were a response to suggestions that crypto companies should shift their focus entirely toward AI. He rejected that idea, saying the two technologies serve different purposes and are stronger when combined.
Coinbase has already begun building products around this vision. The company recently launched tools that allow AI agents to interact with user accounts, execute financial tasks, monitor markets, rebalance portfolios, and perform trades within limits set by users.
The company has also expanded support for x402, a payment protocol designed to enable internet services and websites to request payment automatically during online interactions. Using this system, AI agents can pay for access to digital resources such as data feeds, computing services, and APIs without manual intervention.
At the centre of Coinbase’s strategy are three key technologies:
- x402 for automated internet payments
- Base, Coinbase’s blockchain network, for low-cost settlement
- USDC, the stablecoin used for many transactions
Coinbase says these tools are already being used by AI agents to purchase digital services and complete machine-to-machine transactions. The company has also introduced a marketplace where AI systems can discover and pay for resources such as data, search tools, computing power, and trading services.
Despite the enthusiasm, Armstrong’s prediction remains speculative. There is currently no evidence that AI agents conduct more economic activity than humans, and researchers have raised questions about some of the metrics used to measure adoption. Recent studies have also highlighted potential security risks in machine-payment systems, including concerns about fraud, abuse, and payment verification.
Regulators are paying attention as well. Financial authorities have begun examining how autonomous AI agents might affect markets and payment systems, particularly if automated trading and financial decision-making become more widespread.
Even so, Coinbase continues to position itself at the intersection of AI and crypto. Armstrong’s broader argument is that as AI agents become more capable and independent, they will need a native digital financial system to transact with one another—and he believes cryptocurrency is the technology best suited for that role.
Whether AI agents eventually process more transactions than humans remains to be seen, but Coinbase is clearly betting that the future digital economy will involve both artificial intelligence and blockchain-based payments working together.
