Visa has added Polygon as a settlement chain in its stablecoin program, giving fintech issuers another route to settle card payment flows beyond bank hours. The move targets a key gap in card payments, where user transactions feel instant but issuer settlement can still depend on banking calendars.
Card networks process authorizations in real time, yet settlement between issuers, acquirers, and payment networks often moves later through fiat systems. These include ACH, Fedwire, SEPA, or local payment providers.
That delay creates working-capital pressure for fintech issuers, especially program managers and sponsor-bank-backed firms with large card volumes. Many must cover the timing gap through prefunding or collateral.
With prefunding, an issuer places expected weekend volume into a Visa-held account before banks close. With collateral, an issuer keeps a standing balance available if settlement fails.
Polygon’s addition gives Visa partners access to a chain already used for high-volume USD payment activity. According to data cited by Polygon Labs from Allium and Dune, Polygon recently led USD-based stablecoin payment activity.
The figures show 34% of all USD-based stablecoin transfers happened on Polygon. The share was more than double BNB, the next chain in line.
Polygon also handled 54% of all USDC transfers and 36% of global USDC transactions. Its weekly active stablecoin users reached 3.19 million, while stablecoin supply hit $3.62 billion.
Polygon gives Visa partners a route to settle stablecoin payment flows during weekends and holidays. Instead of waiting for fiat systems to reopen, issuers can use stablecoins while card activity continues. Settlement can be completed in seconds, with finality after confirmed blocks. That can reduce the need for large weekend prefunding balances.
It can also help collateral stay closer to the current exposure rather than a larger weekend estimate. For stablecoin-native fintechs, existing USDC or supported stablecoin balances can support Visa settlement.
For fiat-native fintechs, the process needs conversion, custody, settlement, and reporting. Polygon is positioning its Open Money Stack around that workflow.

Polygon Labs cited throughput above 2,600 transactions per second, roughly five-second finality, and lower fee volatility for institutional payment use. These points matter for firms managing peak periods and reconciliation.
The chain also processed 178.1 million USD-based stablecoin transactions in March. That included 19.8 million peer-to-peer payments, up 46% month over month.
Visa joins Stripe, Revolut, Mastercard, BlackRock, and Flutterwave among firms using Polygon for settlement or payment activity. For Visa partners, the addition creates another settlement option built around stablecoins, cost control, and continuous payment flows.
Visa’s addition of Polygon gives fintech issuers a faster stablecoin settlement route for card payment flows beyond normal banking hours. With strong USDC activity, low fees, and payment-focused infrastructure, Polygon strengthens its role in helping issuers manage weekend, holiday, and high-volume settlement needs.
