Key Takeaways
- Major payment networks Visa, Mastercard, and American Express have declined 18â23% from peak valuations amid stablecoin competition and proposed regulatory changes
- Mastercard’s acquisition of BVNK for as much as $1.8 billion marks the industry’s largest stablecoin-focused transaction
- Visa introduced cryptocurrency command-line infrastructure enabling AI agents to execute payments, while tap-to-pay adoption reaches 80% of in-person purchases
- Stripe unveiled the Machine Payments Protocol with blockchain partner Tempo, supported by $500M in recent capital
- Wall Street forecasts continued earnings expansion in the low-teens range for payment processors in 2026, anticipating collective revenue of $163 billion
The traditional payment processing giantsâVisa, Mastercard, and American Expressâhave experienced significant market corrections from their all-time peaks. Visa shares have retreated 19%, Mastercard is down 18%, and American Express has fallen 23%. The decline stems from two primary catalysts: President Trump’s proposal to impose a 10% ceiling on credit card interest rates, and mounting anxiety that stablecoin technology could disrupt established payment infrastructure.
Stablecoin-based settlement systems offer merchants accelerated transaction finality and substantially reduced processing fees compared to conventional card networks. This competitive threat has triggered investor concern. However, the incumbent payment processors aren’t standing idleâthey’re aggressively adapting their strategies.
Mastercard reached an agreement to purchase BVNK, a stablecoin infrastructure provider, in a deal valued at up to $1.8 billion. The transaction represents the payment industry’s most significant stablecoin acquisition to date. Keefe, Bruyette & Woods analyst Sanjay Sakhrani characterized it as “a critical, long-term strategic move” that establishes Mastercard as a connector between conventional payment systems and stablecoin settlement networks.
Visa hasn’t remained on the sidelines either. The company’s contactless payment technology, which incorporates stablecoin capabilities, now represents 80% of all in-person transaction volume. Additionally, Visa unveiled Visa CLI, a command-line interface enabling artificial intelligence agents to execute card-based payments directly through terminal infrastructure.
Artificial Intelligence Agents Enter the Payment Ecosystem
The competitive landscape extends beyond traditional boundaries. This Wednesday, Stripe partnered with blockchain infrastructure company Tempo to introduce the Machine Payments Protocol, an open framework allowing AI agents autonomous payment capabilitiesâcovering API access, data subscriptions, and computational resourcesâby consolidating numerous micro-transactions into single blockchain settlements.
Tempo secured $500 million in funding last October at a $5 billion valuation. The company’s chief executive is Matt Huang, Paradigm’s co-founder, who simultaneously serves on Stripe’s board of directors.
Initial protocol adopters include Anthropic, OpenAI, DoorDash, Shopify, Revolut, alongside both Visa and Mastercard. The dominant card networks are participating as ecosystem partners, transcending their competitive relationship.
Morgan Stanley estimates agentic commerce could capture $385 billion of U.S. e-commerce transactions by decade’s end. Stablecoin payment volume surged to $33 trillion throughout 2025, representing 72% annual growth.
Critical Implications for Payment Processors
A February 2026 analysis from Citrini Research highlighted a fundamental challenge: AI agents optimized for cost efficiency could detect the 2â3% interchange fees imposed by Visa and Mastercard, then circumvent them entirely by utilizing stablecoin networks where transaction costs measure mere fractions of a cent.
Visa handles $17 trillion in annual payment volume. Current valuations place Mastercard and Visa at approximately 24 and 22 times forward earnings respectively, significantly below their historical valuation multiples. American Express commands roughly 16 times forward earnings.
Financial analysts have actually modestly increased 2026 earnings projections. Consensus expectations point to combined earnings per share growth in the low-teens range, driven by approximately 10% revenue expansion to $163 billion collectively.
Stripe facilitated $1.9 trillion in payment processing during 2025 and completed its 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.”
