TRM Labs examined $52.7 million across 198.9 million settlements on Coinbase’s x402 protocol since May 2025. After filtering out self-payments and anomalous flows to isolate $25.62 million in likely commerce, the firm estimated that AI agents generated only 0.6%–7.5% of the value. The report notes that ordinary scripts can mimic agent behavior by repeating single-service payments, making it difficult to distinguish true autonomous activity from automated tasks without conclusive modeling.

The study highlights significant gaps in accountability, as on-chain agent registries remain voluntary and underutilized. Despite low current usage, major entities continue investing in infrastructure; Binance launched an x402 payment layer with Agent OS, while Amazon introduced AgentCore Payments with Coinbase and Stripe. USDC accounted for 99.6% of settled value, underscoring stablecoin dominance in this emerging market structure.
