Circle and Stripe Bet on Stablecoin Payments for AI Agents

Circle Internet Group, issuer of the dollar-backed stablecoin USDC, still derives most of its revenue from interest earned on cash and U.S. government securities held in reserve. That leaves the company exposed to lower interest rates and swings in digital-asset demand, making revenue diversification strategically important. Circle is betting that autonomous AI agents will need programmable, always-on money to buy data, computing power and digital services, potentially creating a machine-to-machine payments market that card-based infrastructure was not designed to serve.

On Aug. 5, 2026, Circle reported second-quarter USDC circulation of $73.3 billion, up 19% from a year earlier, while onchain transaction volume surged 151% to $14.8 trillion. Revenue rose 7% to $701.3 million and adjusted EBITDA increased 8% to $143 million. Circle had launched Circle Agent Stack on May 11, adding Agent Wallets, an Agent Marketplace and gas-free Nanopayments, as it seeks to turn autonomous-agent activity into a new stablecoin market and a source of transaction-based revenue.

USDC is a fully reserved stablecoin issued by a regulated affiliate of Circle Internet Group and redeemable 1:1 for U.S. dollars. Cross-border payments in Africa have long faced high costs and lengthy settlement times because of fragmented currencies and infrastructure. Sasai Fintech, part of Cassava Technologies, has established operations spanning business payments, personal remittances and mobile wallets.

Circle announced on March 24, 2026, that its affiliate would collaborate with Sasai Fintech to explore integrating USDC and Circle's onchain infrastructure into African payment corridors. Potential uses include business payments, cross-border transfers, remittance services and consumer wallets. The companies have not disclosed any investment amount, launch markets or timetable. Their goal is to reduce costs, transaction friction and settlement times.
