State of Agentic Commerce: July 2026

Welcome to the first issue of State of Agentic Commerce, a monthly read on where this market actually is, written from the seat we sit in. Merit indexes the open agentic commerce ecosystem through x402scan and mppscan, so we watch the on-chain activity as it happens. Here is the short version for July 2026: the protocols are compounding, the builders are showing up, and stablecoins just went mainstream.

The numbers this month

Agentic payments are no longer a demo. Over the last 30 days, agents settled 13.5 million payments over x402 and another 503,632 over MPP, almost all of them for fractions of a cent. Here is where the two open protocols stand as of July 1.

Two things stand out. First, x402 is now a mature, high-frequency network: 185.9 million lifetime payments, and its recent seven-day pace is running hotter than its own monthly average, so the curve is still bending up. Second, MPP is the fastest-ramping protocol in the space. Roughly 38 percent of every MPP transaction ever recorded happened in the last 30 days alone. When more than a third of a protocol's entire history lands in a single month, that is not a trend, that is a takeoff.

The average payment sizes are the other tell. Around seven cents on x402 and eleven cents on MPP. This is the micropayment economy the web could not build in 1997, when card fees made sub-dollar payments impossible. Agents are now transacting below a dime, at scale, every day.

Builder energy

The activity we can measure is matched by the energy we can feel. Resource registrations on x402scan keep climbing as more API providers list what they will sell to agents. A lot of that is hobbyist energy right now, people wiring up a paid endpoint as a weekend project, and that is exactly the shape early ecosystems take before they compound.

The bigger signal is that serious API providers want in. They are excited to sell AI-native goods and services directly to agents, whether that is through open protocols or their own storefronts. Exa, for example, has moved into a vendor marketplace version of this, selling directly to agents through a more closed setup. I think that is good for the ecosystem overall. However sellers choose to reach agents, the fact that they are racing to do it at all tells you where demand is heading.

The stablecoin turn: Open USD

The month's biggest headline came from outside our world. On June 30, a consortium called Open Standard announced Open USD, a dollar-backed stablecoin governed by its members rather than a single issuer. The partner list is the story: more than 140 companies, including Visa, Mastercard, Stripe, American Express, Coinbase, BlackRock, Google Cloud, BNY, IBM, DoorDash, and Fireblocks.

The design is notable. Instead of one company owning the reserve economics, participating institutions can mint and redeem Open USD without volume limits and share the reserve income across the network after costs. Minting and redemption are zero-fee, and the token is planned to launch on Solana, Polygon, Aptos, and Stellar later this year. It is led by Zach Abrams, who previously co-founded Bridge, the stablecoin infrastructure company Stripe acquired in 2024.

You do not need a Merit opinion to see why this matters. When Visa, Mastercard, and BlackRock put their names on a shared stablecoin, the argument about whether stablecoins are a serious payment rail is over. People are finally catching on that stablecoins are simply a better digital payment method. As sales channels shift and agents become the ones transacting, it makes far more sense to rebuild on newer, simpler financial infrastructure built for agents and developers than to force the old rails to do a job they were never designed for. Open USD is one large, institutional expression of that same realization.

What we are watching

Three things we will track into next month:

1. Whether MPP's ramp holds or accelerates now that it has a full month of momentum.
2. Whether more established API providers follow Exa in building agent-facing storefronts.
3. Whether the Open USD consortium ships on schedule, and what settling agent payments in a bank-and-card-backed stablecoin does to volume across the open protocols.

That is the state of agentic commerce for July 2026. We will be back next month with the numbers, and what they mean.
