Incumbents Secure Infrastructure for Stablecoin Adoption

Mastercard and Visa are aggressively acquiring underlying payment infrastructure and testing cross-border settlement to integrate stablecoins into their core systems, reinforcing the thesis that they are absorbing rather than being displaced by crypto rails.

What changed

Major institutional moves indicate a shift toward ownership of the foundational layers for digital assets. Mastercard completed the acquisition of BVNK on August 3, 2026, for up to $1.8 billion—more than double its previous valuation—to secure control over the infrastructure layer. Simultaneously, Visa is testing stablecoin settlement in partnership with Lloyds Bank specifically to facilitate faster cross-border flows. Furthermore, Mastercard has introduced new trust and intelligence services designed to support "agentic commerce," providing a framework for AI agents to conduct transactions safely.

Why it matters

The acquisition of BVNK by Mastercard is a critical move toward infrastructure ownership; by owning the "pipes" rather than just the "lanes," Mastercard ensures that if stablecoins become a primary settlement method, they remain the gatekeepers of the transaction flow. This reduces the risk of disintermediation because it moves the integration from an external partnership to an internal capability. Visa’s testing with Lloyds provides empirical evidence that stablecoins can solve specific friction points in traditional cross-border payments—namely speed and cost—thereby validating their utility as a functional replacement for legacy settlement systems. Finally, Mastercard's focus on agentic commerce trust directly supports the integration of AI into the payment stack; by building safety protocols for autonomous agents, they are preparing to capture the next wave of automated commerce that will rely on stablecoin rails for 24/7 execution.

Opposing sources and risks

Some analysis suggests that the rapid growth and adoption of stablecoins could eventually pose a direct threat to the dominance of Visa and Mastercard. If these networks fail to successfully integrate these assets or if regulatory hurdles create a fragmented landscape, they may lose market share to more nimble, decentralized alternatives.

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.
