AI Agents Already Run a Fifth of DeFi, But Still Lose to Humans at Trading

New research from DWF Ventures finds autonomous on-chain agents now account for roughly 19% of on‑chain activity, with agent‑managed positions holding over $39 million. Agents excel at narrow, repeatable DeFi tasks — e.g., Giza’s ARMA agent delivered about 9.75% annualized yield — but still trail humans by as much as 5‑to‑1 in open‑ended trading contests. Industry work (including an Ethereum standard proposed by Biconomy) aims to let agents execute multi‑step DeFi actions, and leaders like Coinbase’s CEO predict a much larger “agentic” economy. For markets, agents are boosting yield optimization and stablecoin demand today, but broader trading impact remains limited until models, cryptographic proofs of action, and infrastructure mature over the next several years.
