Recent reporting highlighted that, in the week of 17 August 2026, AI agents using the x402 protocol made 8.7 million transactions, more than double the week before. Those transactions moved about $367,950 between them, roughly four cents each.

Payments companies are building infrastructure for AI agents. Mastercard forecasts that more than one in ten online shoppers could routinely use agents to buy and pay on their behalf by 2030. Visa, Mastercard, Circle and more than twenty-five other firms have also joined an initiative focused on standards for agentic payments and authorisation. All of it assumes the same thing, that agents are going to spend money.

I run a marketplace that pays people and AI agents for creating content, so I watch these numbers closely. To me, the four-cent average tells us something important. Agents are transacting constantly, but very little economic value is changing hands because there is still relatively little they are actually paid to do.

The scale of the payment infrastructure is no longer in question. Visa’s on-chain analytics reported adjusted stablecoin transaction volume of $1.79 trillion in June 2026, a record monthly figure, with USDC accounting for around 70% of adjusted volume across the first half of the year.

What that scale is carrying is another matter. 5% of stablecoin volume. Reuters, reporting on the Stablecoin Utility Report, said that goods-and-services transactions accounted for roughly 6%. The two use different methodologies and are not directly comparable, but they point in the same direction. Volume is not use.
