Visa and Artemis Propose Card-Stablecoin Split for AI Commerce; x402 Processed $15M

According to a joint report this week, Visa and Artemis argue that card networks and stablecoins should specialize in different payment types rather than compete. The report, "Agentic Payments from the Ground Up," divides AI-driven commerce into macro-commerce—everyday purchases like travel bookings—handled by card networks, and micro-commerce—small, repeated sub-dollar transfers between software programs—powered by stablecoins. Fixed card fees make tiny payments uneconomical, while blockchain settlement costs have fallen to fractions of a cent, better suited for machine-to-machine transactions.

Onchain data supports the split. Since May 2025, x402—co-built by Coinbase, Cloudflare and now managed by the Linux Foundation—has processed approximately $15 million across 109.6 million payments, mostly on Base, Solana and Polygon. Stripe and Tempo's Machine Payments Protocol settled $25,000 across 115,000 payments in its first weeks. Both platforms confirm that individual transfers remain well under one dollar, validating the need for two separate rails.
