Stablecoins Set to Fuel Autonomous AI Payments Boom

BlackRock's Digital Assets Research team has made a bold prediction about the future of payments in the age of autonomous AI. In a paper titled The Machine-Native Economy: How digital assets connect intelligence, commerce, and compute, published on September 22, 2026, the researchers argue that stablecoins will become the payment rails for these intelligent systems.

The existing financial infrastructure is seen as fundamentally mismatched for the high-frequency, low-cost machine-to-machine payments generated by autonomous AI. Traditional systems like ACH and credit card networks are slow, expensive, and cumbersome, making them unsuitable for real-time transactions between algorithms buying GPU time or data access.

BlackRock's report highlights the explosive growth of stablecoins, with a circulating supply exceeding $300 billion as of September 2026. Adjusted transaction volume topped $11 trillion in 2025 alone, with an annual compounding rate of roughly 80%. In contrast, ACH volume grew at about 8.5% per year over the same period.

The report also touches on the emergence of a new digital asset class: assets tied to tokenized computing capacity. While regulations and market standards for this segment are still in their infancy, 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.
