This Formula Makes Every Trade Safer

SoFi went live with something it says no nationally chartered U.S. bank had done before. On September 22, 2026, SoFi Technologies and Mastercard announced that stablecoin settlement is now live across SoFi Bank, N.A.’s debit and credit card program, bringing settlement through SoFiUSD to Mastercard’s global payments network following a partnership the companies announced in March. As part of the launch, SoFi Bank is migrating its entire $25 billion card program to stablecoin settlement of transactions using SoFiUSD, which the company describes as the first stablecoin issued by a nationally chartered bank.

The stock was trading around $16.97 at Monday’s close before the announcement dropped, down roughly 48% from its November 12, 2025 high of $32.73. Shares climbed about 5% on the news Tuesday. The pre-market read of +4.36% going into Wednesday suggests the market is still working out what this is worth, which is the right instinct. The announcement is real. The revenue model behind it is real too, though early. The valuation case depends entirely on scale.

What SoFiUSD Actually Is and How It Earns

SoFiUSD is a fully reserved U.S. dollar stablecoin issued by SoFi Bank and offered on a public blockchain. SoFi first launched SoFiUSD for institutional use in December 2025 and expanded availability to members in the SoFi app on May 27, 2026. It is designed to hold a value of $1 and can be redeemed one-to-one for U.S. dollars, with reserves backed 1:1 by cash or cash equivalents, primarily held as cash balances at the Federal Reserve.

The revenue mechanics are more straightforward than they sound. CEO Anthony Noto has framed the payoff as running through two lines: fee-based revenue from SoFi’s technology business, and net interest income from leaving that cash at the Federal Reserve and earning overnight interest on it. Every dollar of SoFiUSD in circulation is a dollar parked in SoFi Bank’s reserves, earning overnight interest. At $25 billion in annualized card volume, the float income becomes material at any rate above zero.

On top of the float, interchange economics remain intact. SoFi’s pitch is that merchants do not need to hold stablecoins, build new infrastructure, or change how they operate. Through SoFi’s Big Business Banking platform, the company says merchants can receive settlement funds instantly into a SoFi Bank account and withdraw cash around the clock at zero cost. That framing is deliberate: SoFi is not asking merchants to enter crypto. It is asking them to receive dollars faster, a far easier sell.

The Galileo Multiplier

The single-bank launch is the proof point. The real bet is Galileo. SoFi has said Galileo, its technology platform, is expected to extend SoFiUSD settlement to other issuing banks, turning a single-bank implementation into a broader distribution rail and giving other banks a pathway to stablecoin settlement without building proprietary blockchain infrastructure. Galileo has said it supports over 160 million accounts. If even a fraction of those migrate to SoFiUSD settlement, the float income scales well beyond SoFi’s own card program.

The white-label model can generate recurring technology and custody fees from partner institutions, similar to banking-as-a-service economics. That is the structural shift investors are pricing: from lender to infrastructure issuer.

Bull / Base / Bear

• Bull: Galileo converts several large issuing bank clients to SoFiUSD settlement within four quarters. Float income and technology fees move the needle on the Technology Platform segment. Analyst consensus, currently a Hold at an average target near $20, gets revised upward materially. SOFI re-rates toward prior highs.
• Base: SoFi’s own $25 billion card program runs smoothly on-chain. Float income adds a modest but growing contribution to net interest income. Galileo signs one or two partner banks by mid-2027. The stock recovers gradually as the market gains conviction in execution.
• Bear: SoFi says it is in active discussions with large merchants across the U.S. regarding stablecoin-based settlement arrangements, but no signed contracts have been announced. If merchant and bank adoption stalls, the stablecoin operation becomes a cost center dressed as a strategy pivot, and the stock stays range-bound well below its 2025 peak.

What Investors Should Watch

SoFi’s next earnings date is estimated for October 27, 2026, though the company has not confirmed it. That report is the first chance management has to quantify what SoFiUSD contributes to Technology Platform revenue and to net interest income. Any specific dollar figure attached to float income will move the stock. Equally important: whether Galileo announces a named bank client migrating to SoFiUSD settlement. A named second participant migrating to SoFiUSD within two quarters is the falsifiable trigger for the network-effect thesis.

Bottom Line

SoFi has built something structurally interesting. A bank that issues its own settlement currency earns on the float, keeps interchange, and can license the infrastructure to every bank running on Galileo. The architecture is sound. SoFi Bank received conditional federal charter approval in January 2022 with conditions stating that the bank would not engage in crypto-asset activities or services unless it received a prior written determination of no supervisory objection from the OCC. The fact that SoFi is now issuing a stablecoin used for settlement on a major card network shows how quickly the perimeter is moving. The regulatory window is open. What determines whether SOFI at $17 is cheap or fairly valued is not the announcement itself. It is whether Galileo signs the next bank before the next earnings call.
