Your entire machine-payment ecosystem now runs nearly totally on a single stablecoin. Greater than 98% of all settlements made by AI brokers up to now yr have been processed in Circle’s USDC, in accordance with a brand new report from crypto funding agency Keyrock — a focus that researchers say carries dangers the trade has largely ignored.
One Stablecoin To Rule Them All
Keyrock researcher Ben Harvey, writing in collaboration with Coinbase and blockchain agency Tempo, stated the dependence on one issuer’s infrastructure, regulatory standing, and reserve administration creates a systemic publicity that no person within the house is publicly discussing.
A regulatory problem towards Circle, a de-peg occasion, or perhaps a extended outage would go away the agent economic system with no various settlement possibility. Harvey stated that threat warrants critical consideration as transaction volumes proceed to develop.
In a single yr, machine funds have developed from idea to reside ecosystem, with brokers settling 176M transactions.

The numbers behind the report are hanging. From Might 2025 via April 2026, AI brokers settled over $70 million throughout 176 million transactions — a mean deal dimension of about 31 cents.
That determine alone explains why conventional cost networks have been by no means going to work right here. A typical processing payment of roughly 30 cents per transaction makes something under a greenback utterly unworkable on rails constructed for shopper bank cards. An agent paying three cents to name a climate API can not route via Visa.
Why Conventional Rails Had been Left Behind
Stablecoins crammed that hole not as a result of they have been chosen however as a result of nothing else might do the job. The economics of legacy cost infrastructure merely collapse at sub-dollar volumes, and crypto rails carry no fastened per-transaction payment that will eat the complete worth of a microtransaction.
By the tip of the primary quarter of 2026, greater than 104,000 brokers had been registered throughout 15 or extra directories and registries worldwide.
Harvey described the shift as going from idea to a developed ecosystem in simply 12 months. Incumbents seem to have taken discover — the report says greater than $8 billion has been deployed in acquisitions by established gamers seeking to stake a place in what’s rising as a brand new cost stack constructed round autonomous software program fairly than human customers.

A Market Constructed On One Basis
AI brokers are already getting used to construct Web3 functions, launch tokens, commerce, and work together autonomously with protocols and companies.
A CoinGecko survey of two,632 crypto customers carried out final April discovered 87% have been prepared to let AI brokers handle at the least 10% of their crypto portfolio.
Circle CEO Jeremy Allaire has predicted that billions of brokers will function with stablecoins on customers’ behalf inside 5 years.
