Mainstream Adoption of Stablecoins and Agentic Commerce by Payment Giants

Major payment networks like Visa and Mastercard are moving from pilot programs to large-scale migrations of existing portfolios onto stablecoin rails, while simultaneously building trust infrastructure for AI-driven 'agentic' commerce.

What changed

Recent developments show a significant shift toward the practical integration of stablecoins within major card networks. In September 2026, SoFi Technologies and Mastercard announced that they migrated SoFi’s entire $25 billion card portfolio to SoFiUSD, a bank-issued stablecoin on Mastercard's network. Additionally, Visa reported that nearly half (46%) of consumers in the Asia Pacific region are open to using stablecoins by 2031. On the infrastructure side, Mastercard has introduced new trust and intelligence services specifically designed to support agentic commerce, while Visa is actively testing stablecoin settlement for faster cross-border flows in partnership with Lloyds.

Why it matters

These developments provide strong evidence for the thesis that payment incumbents are absorbing blockchain innovation rather than being replaced by it. The migration of SoFi’s $25 billion portfolio to a bank-issued stablecoin (SoFiUSD) is a critical turning point; it demonstrates that stablecoins are no longer just experimental tools but are becoming viable replacements for traditional settlement layers within existing card programs. This validates the "absorption" narrative by showing how large-scale, established portfolios can be migrated to blockchain rails without discarding the underlying card network infrastructure.

Furthermore, Visa's finding of high consumer openness in Asia (46%) suggests a massive, untapped market for stablecoin-integrated products. This indicates that the demand for faster, 24/7 settlement is already present at the consumer level, providing a clear incentive for Visa to integrate these rails to maintain its dominance.

Mastercard’s shift toward "trust" and "intelligence" in agentic commerce addresses the primary hurdle for AI-driven transactions: how an autonomous agent can be trusted to spend money. By building these safeguards, Mastercard is positioning itself as the essential gatekeeper for automated commerce, ensuring that even if transaction methods change (from human-clicked buttons to AI-agent execution), the payment network remains the central clearinghouse.

Opposing sources and risks

Several factors could challenge this narrative or slow its momentum. The rapid growth of India's Unified Payments Interface (UPI) poses a threat from alternative, non-card-based rails that may gain traction in emerging markets. Additionally, the rise of "Pay-by-Bank" systems offers an alternative to card networks for domestic transactions. On a macro level, the push for sovereign digital currencies (like the Digital Euro) and potential regulatory hurdles regarding stablecoin usage could create friction or force a pivot toward state-backed alternatives rather than private stablecoins.\n

What to watch

  • The growth of RLUSD as it scales its role in institutional settlement compared to USDC.
  • The pace of implementation of KYA (Know Your Agent) identity standards across Mastercard and Visa networks.
  • Growth in volume for custom stablecoins processed via PayPal's PYUSDx platform.
  • Comparative growth rates between stablecoin settlement volumes and UPI transaction volumes.
  • The rate at which "Pay-by-Bank" transactions grow relative to stablecoin-integrated card transactions.
  • Adoption rates and transaction volumes of USDC on MoneyGram-issued Visa cards.
  • Adoption rates and transaction volumes for AgentCard and similar merchant-facing tools.
  • Specific growth metrics for SoFiUSD volume within the Mastercard network.
