Visa disclosed an infrastructure expansion aimed at blockchain lenders issuing stablecoin-linked cards, granting those issuers access to the network's transaction data rails to underwrite loans against on-chain collateral. The move follows 18 months of pilot programs with partners including Fold, Coinbase Card, and BlockFi successor entities, where users spend stablecoins at point-of-sale while issuers extend credit denominated in USD or crypto. Visa's head of crypto product told CNBC the company sees "material velocity" in the cohort—users spending $2,400 monthly on average versus $1,100 for standard rewards cardholders—and wants to standardize the underwriting layer before competitors move.
The new offering packages Visa's existing fraud scoring, merchant-category analytics, and cross-border spend signals into an API bundle that blockchain lenders can query in real time. Issuers using the service will pay a per-query fee and a percentage of loan origination volume, creating a third revenue stream for Visa beyond interchange and network fees. The company estimates 12 million stablecoin-linked cards will be active globally by year-end 2027, up from 1.8 million today, with median spending 40% higher than legacy plastic due to younger demo skew and cross-border use cases. That velocity matters: Visa earns 0.13% on every dollar processed, and stablecoin users transact 22 days per month versus 14 days for standard cardholders.
The second-order effect is balance-sheet leverage for blockchain lenders who previously relied on manual underwriting or Chainalysis-style wallet scoring. With Visa's merchant data, a lender can see that a cardholder spends $600 monthly at grocery and gas before advancing a $3,000 line against USDC reserves, reducing default risk and expanding addressable borrowers. Visa piloted the system with three undisclosed partners in Q2 2026; two reported default rates under 1.2%, in line with prime unsecured cards, while origination volume doubled quarter-over-quarter. The company is now opening the API to any regulated issuer with a program manager agreement and on-chain reserve proof, effectively productizing what was bespoke integration. Meanwhile, Mastercard has been silent on equivalent tooling, and Discover exited crypto partnerships in 2025 after regulatory pressure.
Allocators should watch for Visa's Q4 2026 earnings call in late October, where management typically discloses new business line contribution. If stablecoin card volume breaks out as a standalone metric—currently buried in "processed transactions"—it signals the segment crossed internal materiality thresholds, likely $8B quarterly run-rate. Also watch for partnership announcements with Stripe, which processes 60% of stablecoin card settlements but has no lending arm; a joint venture would bypass traditional credit bureaus entirely. Finally, monitor whether Visa negotiates carve-outs in upcoming state-level stablecoin regulations, particularly in New York and Texas, where lawmakers are drafting reserve-transparency rules that could require real-time API hooks—infrastructure Visa now controls.
The company is building the underwriting layer for a payments category that did not exist 36 months ago, charging rent on both the transaction and the credit decision, at a moment when USDC supply sits near $200B and Circle's IPO roadshow emphasizes merchant acceptance as the next unlock.
