Coinbase CEO: AI Agents May Outnumber Humans in Transactions On September 20, 2026, Coinbase CEO Brian Armstrong @brian_armstrong said in an interview with The Wolf Of All Streets @scottmelker that AI agents may eventually outnumber humans in transactions. He said existing payment systems are not well suited to the speed, global reach and small payments required by agents, creating demand for new financial infrastructure. Coinbase is building toward that future through Base, USDC and the x402 protocol.
