- Mastercard’s acquisition of BVNK for a potential $1.8 billion marks the industry’s biggest stablecoin transaction
- Visa introduced crypto-enabled CLI tools for artificial intelligence payment systems while expanding tap-to-pay coverage to 80% of in-person sales
- Stripe unveiled the Machine Payments Protocol with Tempo blockchain, supported by $500M capital infusion
- Wall Street forecasts continued double-digit profit expansion for card issuers through 2026, targeting $163 billion in collective revenue
The payment processing industry’s leading players have witnessed dramatic valuation corrections from all-time peaks. Visa has retreated 19%, Mastercard declined 18%, while American Express experienced the steepest drop at 23%. The downturn stems from twin pressures: President Trump’s proposal to cap credit card interest rates at 10%, combined with mounting anxiety over stablecoin technology potentially undermining traditional card network business models.
Stablecoin technology enables retailers to complete transaction settlements more rapidly and economically compared to conventional card processing systems. This capability has triggered investor apprehension. However, the established payment processors aren’t remaining passive—they’re aggressively adapting to stay competitive.
Mastercard announced plans to purchase BVNK, a stablecoin technology provider, in a transaction valued at up to $1.8 billion. This represents the stablecoin sector’s most significant acquisition to date. 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 infrastructure and emerging stablecoin networks.
Visa hasn’t stayed on the sidelines either. The company’s contactless payment technology, integrated with stablecoin capabilities, currently represents 80% of all in-person transaction volume. Additionally, Visa introduced the Visa CLI, a command-line interface enabling artificial intelligence systems to execute card-based payments autonomously through terminal access.
Artificial Intelligence Systems Enter the Payment Ecosystem
The competitive landscape expanded significantly this week. On Wednesday, Stripe partnered with blockchain venture Tempo to introduce the Machine Payments Protocol, establishing an open framework allowing AI agents to autonomously purchase services—including API access, data subscriptions, and computing resources—by consolidating numerous micro-transactions into singular blockchain settlements.
Tempo secured $500 million in financing at a $5 billion valuation last October. The company’s chief executive is Matt Huang, Paradigm’s co-founder, who simultaneously serves on Stripe’s board of directors.
The protocol’s initial ecosystem participants include Anthropic, OpenAI, DoorDash, Shopify, Revolut, alongside both Visa and Mastercard. The traditional card networks are functioning as partners in this innovation, not merely rivals.
Morgan Stanley’s research indicates agentic commerce could capture $385 billion of U.S. electronic commerce by 2030. Stablecoin transaction volumes reached $33 trillion throughout 2025, representing 72% annual growth.
What’s at Risk for Payment Networks
A February 2026 analysis from Citrini Research highlighted a specific vulnerability: AI agents, optimized for cost efficiency, may detect the 2–3% interchange fees imposed by Visa and Mastercard and circumvent them by utilizing stablecoins, where transaction expenses measure mere fractions of cents.
Visa handles $17 trillion in annual payment volume. Current market valuations place Mastercard and Visa at approximately 24 and 22 times forward earnings respectively, significantly beneath their traditional premium multiples. American Express currently commands roughly 16 times forward earnings.
Financial analysts have marginally increased 2026 profit projections. Expectations call for aggregate earnings per share across the sector to expand in the low-teens percentage range, driven by approximately 10% revenue expansion toward $163 billion combined.
Stripe processed $1.9 trillion in transactions throughout 2025 and completed the acquisition of stablecoin infrastructure provider Bridge for $1.1 billion, strategically positioning itself to control payment infrastructure rather than compensate card networks for network access.
Huang acknowledged that “agentic payments is very early, and we still are figuring out the best way to structure these.”
