SoFi's Deposits Hit $45.5 Billion, Up 33-Fold Since It Became an Actual Bank

SoFi Technologies didn't just build an app. It built a bank, and the deposit numbers show it.

According to Crypto Briefing, SoFi's deposits sat at $1.2 billion on March 31, 2022. By March 31, 2026, that figure hit $40.2 billion. By the end of Q2 2026, deposits reached approximately $45.5 billion, a roughly 33-fold increase in four years.

The turning point was SoFi's completed acquisition of Golden Pacific Bancorp, which closed in early 2022 and handed the company a national bank charter, as reported by The Motley Fool. Before that deal, SoFi funded loans through securitized debt and warehouse credit lines, the same expensive, third-party route most fintech lenders still use.

Why a Charter Changes the Math

A bank charter lets a company take FDIC-insured deposits and lend directly against them. NPR's Indicator team laid out the prize structure plainly: deposit insurance from the FDIC, access to the Federal Reserve's discount window, and a Fed master account that lets a bank move money directly through the central banking system.

Without a charter, fintechs like Upstart and Affirm have to pay a bank partner a fee or split interest income just to get a loan funded, according to The Motley Fool. That eats into margins on every single loan.

SoFi doesn't have that problem anymore. Deposits now make up 94% of SoFi's total liabilities, which stood at $42.9 billion as of Q1 2026, up from just 17% four years earlier, per Crypto Briefing. The company reported a net interest margin of 5.94% in Q1 2026, and net interest income climbed from $252 million in 2021 to more than $2.2 billion in 2025.

That funding advantage also buys flexibility. Seeking Alpha reported SoFi sold or transferred $4.1 billion in Q2 2026 loans, with personal-loan execution reaching 106.5% of principal value, and closed loan securitizations totaling roughly $1.4 billion at spreads of 91 and 86 basis points. Upstart and Affirm, without a deposit base to fall back on, don't have the same option to hold loans when it's profitable or sell them when premiums are strong.

The Charter Rush Is Accelerating

SoFi isn't alone anymore. NPR reported that the Office of the Comptroller of the Currency approved 14 bank charter applications in 2026 through August, double the number for all of 2025. Regulators, per NPR, have eased requirements that used to make charters nearly impossible for fintechs to obtain.

Mercury, a startup-focused fintech run by CEO Immad Akhund, filed for a charter last year and got conditional approval from one of the three agencies it needs sign-off from in April, according to NPR. Michele Alt of the Klaros Group, which advises fintechs through the charter process, told NPR the payoff is real but the scrutiny that comes with it is heavier too.

Seeking Alpha also flagged that competitors are closing in on SoFi's head start, pointing to Chime's $590 million acquisition of Stride as validation that the deposit-funded model works, and a sign rivals are racing to copy it.

The Crypto Wrinkle

SoFi is now stretching its bank charter into digital assets. American Banker reported that SoFi is partnering with Payward, the parent company of Kraken, connecting Kraken's institutional customers to SoFi's dollar settlement network for round-the-clock clearing outside normal banking hours. SoFi will also put its SoFiUSD stablecoin on Kraken's trading platforms and use Kraken Prime as a digital-asset liquidity source.

Leo D'Acierno, a senior advisor at Simon-Kucher, told American Banker that SoFi is "betting on a vision of core banking fully integrated with digital assets." Coin Bureau founder Nic Puckrin told the outlet the relationship between regulated banks and crypto firms is becoming "symbiotic," with each side needing what the other has.

A federally chartered, deposit-taking bank plugging FDIC-backed infrastructure into crypto exchanges and stablecoins raises the stakes if something goes wrong. Deposit insurance and Fed discount window access exist to protect the traditional banking system, not to backstop crypto trading platforms. Whether the OCC's faster charter approvals in 2026 come with commensurate oversight of these crypto tie-ins is a fair question none of the current reporting answers.

No regulator has announced a specific investigation into the SoFi-Kraken arrangement, and no source in this record raises a formal objection to it. The arrangement is new business activity under an existing charter, not a novel license.

What happens next is straightforward to track: SoFi trades at roughly 21 times projected 2027 earnings, according to Seeking Alpha, a multiple that assumes continued growth in institutional adoption of its settlement network and its stablecoin. Whether that bet on crypto-bank integration pays off, or whether it invites the kind of regulatory pushback that slowed fintech charters for most of the last decade, is still an open question heading into 2027.
