SoFi Bank goes live settling Mastercard cards in SoFiUSD stablecoin

SoFi Technologies and Mastercard said stablecoin settlement is now live across SoFi Bank, N.A.’s debit and credit card program, with the bank migrating its entire card book—expected to process more than $25 billion in annualized volume—to settlement in SoFiUSD. The September 22 Business Wire / FT company announcement frames SoFi Bank as the first nationally chartered U.S. bank to go live with bank-issued stablecoin settlement on Mastercard’s global payments network, following a partnership first announced in March. Transactions, the companies said, are live on the blockchain today.
Marketplace Watch cares because this is settlement plumbing, not a new NFT mint page. Merchants accepting SoFi-issued cards still collect as they always have; Mastercard’s network routes settlement through SoFiUSD on-chain. SoFi CEO Anthony Noto said merchants do not need to hold stablecoins, build new infrastructure, or change how they operate—settlement funds can land in a SoFi Bank account via Big Business Banking and withdraw to cash around the clock at zero cost, in the company’s telling. Mastercard Global Head of Digital Commercialization Sherri Haymond called the move a shift “beyond exploration to implementation” inside a live production environment while keeping Mastercard’s trust and scale expectations.
SoFiUSD is issued by SoFi Bank, N.A., an OCC-regulated nationally chartered bank, described as fully redeemable 1:1 for U.S. dollars and supported by reserves consisting primarily of cash. It is positioned for institutional use and SoFi members. Solana Compass same-cycle coverage adds chain mix detail the FT wire does not lead with: of roughly $332 million SoFiUSD in circulation as of late August 2026, about $232.6 million (~70%) sits on Solana and roughly $100 million (~30%) on Ethereum. Mastercard added Solana to its stablecoin settlement network in June 2026 alongside Arbitrum, Base, Canton, Ethereum, Polygon, Tempo, and XRPL—SoFi’s card program now rides that multi-chain settlement stack.
Expansion language is as important as the day-one claim. SoFi said it is in active discussions with large U.S. merchants—from multinational retailers to tech platforms—about stablecoin-based settlement arrangements beyond the bank’s own cards. SoFi and Mastercard also plan to explore SoFiUSD settlement for cross-border payments, remittances, and other money-movement cases, and Solana Compass notes Galileo (SoFi’s payments-tech subsidiary) as a path to extend the rail to other issuers. Other early Mastercard stablecoin-settlement participants named in ecosystem coverage include ARQ, CBW Bank, Cross River, Lead Bank, and Nuvei—SoFi’s “first nationally chartered bank live” claim is about charter tier, not about being the only network participant.
For NFT and crypto desks, the signal is bank-issued dollars clearing plastic volume on public chains—especially Solana’s share of SoFiUSD—rather than a collector marketplace redesign. Cite the live go-live, the $25B annualized card-program figure, SoFiUSD’s bank issuance and 1:1 redemption language, merchant no-hold UX, the March partnership → six-month build, and the ~70/30 Solana/Ethereum supply split from Solana Compass. Do not invent merchant SoFiUSD wallets, DTC share equivalence, or guaranteed Galileo client adoption.
Context against other Solana payment headlines: Visa’s USDC-on-Solana settlement program has been cited near a $7 billion annualized run rate in mid-2026 secondary coverage, while SoFiUSD’s late-August float (~$232.6M on Solana) is smaller—but it arrives as OCC-bank paper clearing tens of billions in card volume rather than as a DeFi-native stablecoin float. That distinction is why Marketplace Watch logs the Mastercard go-live even when SoFiUSD remains a fraction of Solana’s broader stablecoin supply (USDC alone was cited near $8.09 billion on Solana in the same Solana Compass wrap).
Bottom line: SoFi Bank is live settling its $25B+ Mastercard card program in bank-issued SoFiUSD—with ~70% of SoFiUSD supply on Solana in late-August figures—turning stablecoin settlement from a pilot talking point into production card rails.
