SoFi projects $25 billion a year of Mastercard settlement through a $300 million stablecoin
SoFi Bank began settling its Mastercard debit and credit card program in its own SoFiUSD stablecoin on September 22, projecting more than $25 billion a year. The revenue case depends on outside banks buying the service through SoFi's Galileo platform, and none has publicly committed.
The Investor · Invest desk
What happened
- SoFi says it is the first US national bank to run live stablecoin settlement across Mastercard's network, a claim that comes from the company itself.
- SoFiUSD is regulated by the Office of the Comptroller of the Currency, fully reserved in cash or cash equivalents, and redeemable one-for-one for dollars.
- Merchants on the card program receive ordinary dollars and never have to hold or handle SoFiUSD.
- SoFiUSD reached about 15 million SoFi app users in May 2026, two months after SoFi and Mastercard formed their settlement partnership.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint Paying merchants in dollars means the card program cannot build merchant balances of SoFiUSD, so circulation has to grow through app users or the direct merchant deals SoFi plans.
- exposure App users holding SoFiUSD own a bank-issued dollar token with no FDIC cover, a difference from a deposit that the issuer's status as a bank makes easy to miss.
- precedent If SoFi's first-mover claim holds, an OCC-regulated national bank has stablecoin settlement in production on Mastercard, giving other regulated banks a working model to copy or to buy through Galileo.
Spread over a calendar year, more than $25 billion of projected volume [1] comes to at least $68.5 million of card settlement a day [16]. Against the roughly $300 million of SoFiUSD outstanding at the end of the second quarter [7], that is about 23% of the tokens in existence moving every day, or the whole float turning over some 83 times a year [17][18]. Crypto Briefing notes that circulation and settlement volume measure different things, since the same dollars can be used repeatedly [10]. The circulation figure is also 84 days older than the launch [19].
With merchants paid in dollars and cardholders seeing no change [8][9], the token has one job in the card program: the leg between SoFi and Mastercard, where settlement on Ethereum and Solana can run around the clock [6]. The $25 billion is therefore a forecast of spending on SoFi's own debit and credit cards [20].
If that volume arrives and circulation stays near $300 million, SoFi has moved its own settlement onto a token it issues, and any gain shows up in its cost base. The report does not include fees, cost savings, or what, if anything, SoFi earns on the cash and cash equivalents behind the token [4]. If outside banks sign up through Galileo, as SoFi intends [13], the token becomes a product SoFi sells to other lenders. If the volume falls short, the caveat is already on record: $25 billion is a projection for a program that has only just gone live [2].
I think the near-term gain is in SoFi's own settlement costs. In my view the nearly 5% rise in the shares on the day [15] priced the Galileo pitch more than the card program. The counter-case is fair. A bank weighing Galileo will want to see a working program before it signs, and in six months SoFi has gone from a partnership agreement with Mastercard in March to a live program in September [11][3]. This view is wrong if a named outside bank signs a Galileo settlement contract within the next few quarters.
What to watch
- SoFiUSD circulation in SoFi's next quarterly report, set against the roughly $300 million at the end of the second quarter.
- The first named large US merchant to sign a direct SoFiUSD arrangement, after SoFi reported interest from several without detailing any.

Claim ledger
Ranked by verification strength, evidence, and original report placement.
- [1]
SoFi projects the card program will process more than $25 billion in transactions each year.
- [2]
The $25 billion figure is a projection, not a track record, and the program has only just gone live.
- [3]
On September 22, 2026, SoFi Bank began settling its debit and credit card program with SoFiUSD on Mastercard's global network.
- [4]
SoFiUSD is fully reserved, regulated by the Office of the Comptroller of the Currency, and redeemable 1:1 for US dollars; its reserves consist of cash or cash equivalents.
- [5]
SoFiUSD is not FDIC-insured and does not carry the same protection as a standard bank deposit; users holding it need to grasp that it lacks FDIC coverage even though it comes from a bank.
- [6]
SoFiUSD lives on public blockchains, starting with Ethereum and Solana, allowing settlement around the clock and supporting programmable payments.
- [7]
By the end of Q2 2026, SoFiUSD had roughly $300 million in circulation.
- [8]
Merchants never have to hold or handle SoFiUSD directly; they receive ordinary fiat currency.
- [10]
Circulation is how many tokens exist at a given moment, while settlement volume is how much value flows through them over a year, so the same dollars can be used repeatedly.
- [11]
SoFi and Mastercard formed a strategic partnership in March 2026 to enable stablecoin settlement on Mastercard's network.
- [12]
In May 2026, two months after the March partnership, SoFiUSD became available to around 15 million SoFi app users.
- [13]
SoFi intends to offer its stablecoin settlement services to other banks through Galileo, its technology platform, and plans to pursue direct arrangements with merchants.
- [14]
Other banks have not yet publicly committed to using Galileo for stablecoin settlement.
- [16]
More than $25 billion a year is at least about $68.5 million of card settlement per day.
- [17]
Daily settlement of about $68.5 million is about 23% of the roughly $300 million of SoFiUSD in circulation at the end of Q2 2026.
- [18]
Settling $25 billion a year on a $300 million float implies the float turns over about 83 times a year.
- [19]
The $300 million circulation figure, measured at the end of Q2 2026 (June 30), is 84 days older than the September 22 launch.
- [20]
Because merchants receive fiat and cardholders see no change, the projected $25 billion is transaction spending on SoFi's own debit and credit cards settled through SoFiUSD.
- [21]
SoFi claims the launch makes it the first national bank in the US to run live stablecoin settlement across Mastercard's network.
- [22]
SoFi reported interest from large US merchants in possible partnerships; none of those arrangements have been detailed publicly.
