Quick Summary
- Major payment networks Visa, Mastercard, and American Express have experienced 19–23% declines from peak valuations, driven by stablecoin disruption concerns and Trump’s rate cap proposal
- Mastercard made history with a $1.8 billion acquisition of stablecoin infrastructure provider BVNK
- Visa rolled out crypto-enabled CLI tools for AI-driven payments and expanded tap-to-pay functionality to 80% of in-person transaction volume
- Stripe partnered with blockchain firm Tempo to introduce the Machine Payments Protocol, supported by $500M in capital
- Wall Street forecasts low double-digit earnings expansion for payment processors in 2026, with aggregate revenue expected to reach $163 billion
The traditional payment processing giants—Visa, Mastercard, and American Express—have experienced substantial stock price corrections from their all-time peaks. Visa shares have retreated 19%, Mastercard has fallen 18%, and American Express has declined 23%. The dual catalysts behind this downturn include President Trump’s proposal for a 10% ceiling on credit card interest rates and mounting anxiety over stablecoin technology potentially disrupting the established card network business model.
Stablecoin technology enables retailers to complete payment settlements more rapidly and economically compared to conventional card processing networks. This competitive threat has rattled investor confidence. However, instead of remaining passive, the payment industry leaders are aggressively pursuing strategies to stay ahead of the disruption curve.
Mastercard struck a deal to purchase BVNK, a stablecoin infrastructure provider, in a transaction valued at up to $1.8 billion. This represents the most substantial stablecoin acquisition on record. Keefe, Bruyette & Woods analyst Sanjay Sakhrani characterized the move as “a critical, long-term strategic move” that establishes Mastercard as a connector between conventional payment systems and stablecoin infrastructure.
Visa hasn’t remained on the sidelines either. The company’s contactless payment technology, which incorporates stablecoin functionality, now represents 80% of all in-person payment transactions. 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
The narrative expands significantly from this point. This past Wednesday, Stripe partnered with blockchain venture Tempo to unveil the Machine Payments Protocol, an open framework allowing AI agents autonomous payment capabilities for services—including API requests, data subscriptions, and computing resources—consolidating numerous micro-transactions into single blockchain-based settlements.
Tempo secured $500 million in funding last October at a $5 billion company valuation. The firm’s chief executive is Matt Huang, Paradigm co-founder, who maintains a board position at Stripe.
Initial adoption partners for this protocol encompass Anthropic, OpenAI, DoorDash, Shopify, Revolut, alongside both Visa and Mastercard. The two payment network leaders are working cooperatively in this space, transcending their typical competitive relationship.
Morgan Stanley forecasts that agentic commerce could capture $385 billion of U.S. online retail by 2030. Stablecoin payment volume reached $33 trillion throughout 2025, representing 72% annual growth.
What’s at Risk for Payment Processors
A February 2026 analysis from Citrini Research highlighted a specific vulnerability: AI agents, optimized for cost efficiency, may detect the 2–3% interchange charges levied by Visa and Mastercard and circumvent them by utilizing stablecoins, where transaction expenses measure mere fractions of a cent.
Visa handles $17 trillion in annual payment volume. Both Mastercard and Visa currently command forward price-to-earnings multiples of approximately 24 and 22 respectively, significantly compressed from their historical valuation premiums. American Express trades near 16 times forward earnings.
Interestingly, analysts have modestly increased 2026 profit projections. They anticipate consolidated earnings per share for these companies to expand in the low-teens percentage range, supported by roughly 10% revenue growth toward $163 billion collectively.
Stripe handled $1.9 trillion in payment volume during 2025 and completed the acquisition of stablecoin infrastructure provider Bridge for $1.1 billion, strategically positioning itself to control the underlying infrastructure rather than compensating card networks for transaction access.
Huang acknowledged that “agentic payments is very early, and we still are figuring out the best way to structure these.”
