SoFi launched SoFiUSD. It’s live on Mastercard’s network, and the company wants $25 billion in annualized transaction volume out of it.
That’s a big number for a stablecoin program that’s basically just getting started. SoFiUSD is built to handle settlement on SoFi’s card program, using blockchain rails instead of the traditional back-end plumbing that most card issuers still rely on. The idea is faster, cheaper transactions — fewer friction points between the moment a user swipes and the moment money actually moves. Whether it delivers on that in practice is still unclear, but the target volume alone puts this in a different league from most stablecoin pilots. Most fintech stablecoin experiments stay small, stay quiet, and fade out. SoFi is going the other direction, at least on paper.
What SoFiUSD Actually Does
The stablecoin isn’t a consumer-facing product in the traditional sense. It’s a settlement layer. When a SoFi cardholder makes a transaction, SoFiUSD handles the back-end settlement on Mastercard’s network rather than going through conventional clearing processes. That’s the pitch: blockchain efficiency grafted onto an existing, massive payments infrastructure. Mastercard’s network is one of the largest on earth, which is kind of the point — you don’t get to $25 billion in annualized volume on a small network.
SoFi didn’t disclose specific operational details about how the settlement mechanics work at a technical level. No word on custody arrangements, reserve structure, or exactly how SoFiUSD maintains its peg. Those details matter, and they’re not out yet. For now, the company has confirmed the service is live and that it’s tied to the card program’s volume ambitions.
The Mastercard angle is worth sitting with for a second. Partnering with a legacy payments giant to run a stablecoin settlement layer is a pretty deliberate signal. It’s not a crypto-native play. SoFi isn’t trying to pull users onto a new blockchain wallet or convince anyone to hold a volatile asset. It’s taking stablecoin infrastructure and plugging it into something people already use every day — a debit or credit card. That’s a different bet than most of what the stablecoin market has tried before.
The $25 Billion Target and What It Means
Twenty-five billion dollars in annualized transaction volume would be significant for any stablecoin program, full stop. The broader stablecoin market has grown sharply in recent years, with major players processing hundreds of billions in monthly volume across chains. But most of that activity is concentrated in crypto-native use cases — trading, DeFi, cross-border transfers. Stablecoin settlement embedded directly in a consumer card program at this scale is a different animal.
If SoFi hits anywhere close to that target, it would put SoFiUSD among the more consequential stablecoin deployments in mainstream finance. Not the largest by raw volume, but notable for where the volume comes from — everyday card spending by retail users, not crypto traders.
And that’s probably what SoFi is banking on. The company has spent years building a financial services platform aimed at a younger, digitally comfortable demographic. Adding stablecoin settlement to its card program fits that positioning. It’s a tech upgrade that users may never notice directly but that could make the product faster and cheaper to run.
The Mastercard partnership gives SoFi reach it couldn’t build on its own. Mastercard’s acceptance network spans millions of merchants globally. Running SoFiUSD across that infrastructure, even for a subset of transactions, means the stablecoin has a real-world use case from day one — not a theoretical one.
What’s Still Unknown
Plenty, honestly. SoFi and Mastercard haven’t said much about how user adoption will be tracked, what happens if the stablecoin mechanism runs into stress, or whether additional features are coming. The $25 billion figure is a target, not a guarantee. It’s unclear what timeline they’re working against to hit it.
There’s also the broader regulatory picture. Stablecoin legislation in the U.S. has been a moving target for years. Any large-scale stablecoin program operating on a major card network will draw scrutiny eventually. SoFi didn’t address that directly.
No details on user-facing features, either. Whether cardholders will see any difference in their experience — faster refunds, lower fees, something else — hasn’t been spelled out. The companies say more details are forthcoming as the program unfolds.
For now, SoFiUSD is live, Mastercard’s network is the venue, and $25 billion is the stated ambition.
Frequently Asked Questions
What is SoFiUSD and how does it work?

Why It Matters
The launch of SoFiUSD on Mastercard's network represents a significant move towards the integration of blockchain technology in mainstream payment systems, potentially reshaping how transactions are processed in the financial sector. If successful, achieving the targeted $25 billion in annual transaction volume could not only validate the use of stablecoins for everyday transactions but also encourage other financial institutions to explore similar initiatives, thereby accelerating the adoption of digital currencies in retail environments. This development underscores the growing trend of fintech companies leveraging blockchain to enhance transaction efficiency and reduce reliance on traditional banking infrastructure.
