BlackRock predicts stablecoins will become the payment rails for autonomous AI
A new research paper from the world's largest asset manager argues that AI agents need programmable money, and stablecoins are first in line to provide it.
BlackRock’s Digital Assets Research team published a paper titled “The Machine-Native Economy: How digital assets connect intelligence, commerce, and compute” during the week of September 22, 2026. The core argument is straightforward: autonomous AI systems need to pay for things, existing financial plumbing cannot handle that job, and stablecoins can.
Why legacy payment rails struggle with machine-to-machine transactions
BlackRock’s paper identifies traditional systems, including ACH and credit card networks, as fundamentally mismatched for the low-cost, high-frequency, machine-to-machine payments that autonomous AI systems will generate. The settlement times, fees, and intermediary requirements that are tolerable for human-initiated commerce become structural bottlenecks when the counterparty is an algorithm buying GPU time or data access in real time.
The report also floats the possibility that an entirely new digital asset class could emerge, specifically assets tied to tokenized computing capacity. Regulations and market standards for that segment are still taking shape.
The numbers behind the thesis
Stablecoin circulating supply crossed $300 billion by September 2026. Adjusted transaction volume topped $11 trillion in 2025 alone. Since 2020, stablecoin transaction volume has compounded at roughly 80% annually. Over the same period, ACH volume grew at about 8.5% per year.

According to a TRM Labs analysis cited in the report, AI agents currently account for somewhere between 0.6% and 7.5% of activity across leading payment protocols. Analysts project cloud industry revenues from Amazon, Microsoft, and Google to reach roughly $1.1 trillion by 2030. Cumulative investment in AI infrastructure between 2025 and 2030 could exceed $5 trillion.
What investors and market participants should watch
The stablecoin market is not monolithic. Tether’s USDT and Circle’s USDC dominate by volume, but the AI-payments use case could create demand for stablecoins optimized for specific characteristics, such as programmability depth, cross-chain interoperability, or compliance features that enterprise AI deployments require. BlackRock’s paper acknowledges that standards and rules for tokenized compute markets are still forming, and stablecoin legislation in the US has been a slow-moving process.
