Visa (V) and Mastercard (MA) Battle Stablecoin Disruption With Bold 2026 Strategies

Key Takeaways

• Payment network stocks have declined 18–23% from peak levels amid concerns over stablecoins and proposed interest rate regulations
• Mastercard completed its biggest-ever crypto acquisition, buying BVNK for a maximum of $1.8 billion
• Visa introduced crypto-enabled innovations including an AI-focused payment tool and expanded contactless payment adoption to 80% of in-person sales
• Stripe unveiled the Machine Payments Protocol with blockchain partner Tempo, supported by $500 million in capital
• Wall Street forecasts low-teen percentage earnings expansion for card issuers in 2026, with aggregate revenue reaching $163 billion

The major payment card networks have experienced significant declines from their all-time peaks. Visa has retreated 19%, Mastercard 18%, and American Express 23%. The downturn stems from two primary catalysts: President Trump’s floated proposal to impose a 10% ceiling on credit card interest rates, plus mounting anxiety that stablecoin technology threatens the card industry’s business model.

Stablecoin technology enables retailers to complete payment settlements more rapidly and economically compared to conventional card infrastructure. This competitive threat has rattled market participants. However, instead of maintaining a defensive posture, the payment giants are proactively adapting their strategies.

Mastercard announced its acquisition of BVNK, a stablecoin technology provider, in a transaction valued at as much as $1.8 billion. This represents the most significant stablecoin-related transaction on record. Keefe, Bruyette & Woods analyst Sanjay Sakhrani characterized the deal as “a critical, long-term strategic move” that establishes Mastercard as a connector between conventional payment systems and emerging stablecoin infrastructure.

Visa has similarly taken action. The company’s contactless payment technology, which integrates stablecoin capabilities, now represents 80% of all in-person transaction volume. Additionally, Visa introduced Visa CLI, a command-line interface enabling artificial intelligence agents to execute card-based payments directly through terminal systems.

Artificial Intelligence Systems Enter the Payment Ecosystem

This development extends beyond traditional competition. This week, Stripe partnered with blockchain venture Tempo to introduce the Machine Payments Protocol, an open framework allowing AI systems to autonomously purchase services — including API access, data subscriptions, and computational resources — by consolidating numerous micro-transactions into single blockchain-based settlements.

Tempo secured $500 million in financing at a $5 billion valuation last October. Its chief executive is Paradigm co-founder Matt Huang, who simultaneously serves on Stripe’s board of directors.

Initial partners supporting the protocol encompass Anthropic, OpenAI, DoorDash, Shopify, Revolut, plus both Visa and Mastercard. The competing card networks are functioning as partners in this initiative, not merely rivals.

Morgan Stanley estimates agentic commerce could represent $385 billion of U.S. online retail by 2030. Stablecoin payment volume reached $33 trillion throughout 2025, representing 72% annual growth.

Implications for Payment Infrastructure

A February 2026 analysis from Citrini Research highlighted a specific risk: AI agents, optimized to minimize expenses, might detect the 2–3% interchange fees imposed by Visa and Mastercard and circumvent them by utilizing stablecoins, where processing costs measure fractions of a cent.

Visa handles $17 trillion in annual volume. Mastercard and Visa currently command forward earnings multiples of approximately 24 and 22 times respectively, substantially beneath their historical valuation premiums. American Express trades at roughly 16 times forward earnings.

Analysts have modestly increased 2026 profit projections. They anticipate combined earnings per share for the sector to expand in the low-teen percentage range, driven by approximately 10% revenue growth toward $163 billion.

Stripe handled $1.9 trillion in payment volume during 2025 and purchased stablecoin technology firm Bridge for $1.1 billion, strategically positioning itself to control payment infrastructure rather than compensate card networks for system access.
