SoFi Bank, N.A. held $46.8bn of deposits on 30 June. That is enough for 47th place among all United States banks in the Federal Deposit Insurance Corporation's annual Summary of Deposits, published this week — and the first time a bank that began life as a financial technology company has appeared in the top 50 at all.

The milestone is narrow and the arithmetic behind it is not. SoFi was founded in 2011 to refinance student loans for graduates of selective universities. It had no charter, no insured deposits and no ability to hold the loans it made. Two years ago, in June 2024, its bank held $22.9bn. The figure has roughly doubled since.

What $22.3 million bought

The pivot has a date and a price. In February 2022 SoFi completed the purchase of Golden Pacific Bancorp, a three-branch bank in Sacramento, for $22.3m. It was not buying a franchise. It was buying a national bank charter, and with it the right to take insured deposits.

That distinction is the whole story, and it is a funding-cost story rather than a customer-acquisition one. Before the charter, SoFi financed its lending the way non-banks do: warehouse lines from other banks, priced above what a depositor would accept for the same money. After it, the loans could sit against deposits.

SoFi's own second-quarter filing puts a number on the difference. The average rate it pays on deposits runs 156 basis points below the rate on its warehouse facilities — an annualised interest-expense saving the company quantifies at roughly $712.6m. Against GAAP net revenue of $1.218bn for the quarter and net income of $156.6m, that is not a line item. It is the business model.

Two numbers that do not match, and why

Readers comparing figures will find two. The FDIC's Summary of Deposits shows $46.8bn at SoFi Bank, N.A. SoFi Technologies' own results release for the same date reports total deposits of $45.5bn, up $5.3bn on the quarter. Both are correct. The Summary of Deposits is a branch-level survey of the insured depository itself, filed to a specific regulatory definition; the earnings release consolidates the holding company and nets certain items against it. The gap is about 3 per cent and it is definitional, not a discrepancy.

The underlying growth is the same in either frame. Deposits rose by more than $5bn in a single quarter. Membership reached 15.8 million, up 35 per cent year on year, with 24.4 million products open, up 42 per cent. Net interest margin was 5.98 per cent — a figure most regional banks would need a specialist lending book to reach.

The rate is the price of entry, not the advantage

It is tempting to read the deposit growth as bought. SoFi does price near the top of the retail market: its published rates, current as of late May, show 3.10 per cent on savings for customers with qualifying direct deposit or $5,000 of deposits every 31 days, 0.80 per cent without, and 4.50 per cent on the first $20,000 for holders of the $10-a-month SoFi Plus subscription.

Those are competitive rates. They are not, on their own, an explanation, because paying up for deposits is the oldest and least defensible strategy in banking and it has bankrupted people for two centuries. What makes it work here is what sits on the other side of the balance sheet. A deposit is only worth paying 3.10 per cent for if the assets it funds yield considerably more, and SoFi's assets — personal loans, student refinancing, home lending — do. Regional banks defending their deposit bases with software are trying to hold onto funding that supports a much thinner spread.

The direct-deposit condition is the other half. A savings balance chasing yield leaves for the next quarter-point. A paycheque arriving every fortnight does not. SoFi has priced the two differently on purpose.

What the same report says about everyone else

The Summary of Deposits carried a second number worth more attention than the first. Between July 2025 and June 2026 the count of US banks fell by 182 — the largest annual decline since 2020. There are now 4,249. In 1994 there were 13,002; in mid-2007, on the eve of the crisis, 8,605.

So a fintech entered the top 50 in the same year that 182 chartered banks left the industry altogether. The two facts are not unrelated. The cost of running a small depository — compliance, technology, deposit competition from anyone with an app — has risen faster than the revenue a community bank can generate from a branch network. The charter that was expensive to obtain and modest in value forty years ago is now cheap to buy secondhand and enormously valuable to whoever can put a national distribution channel behind it.

Chime is doing the opposite, deliberately

The obvious question is who follows. Chime, which opens new checking accounts faster than most of the largest US banks, announced this month that it would acquire Stride Bank. But it has said it intends to keep assets below $10bn for the foreseeable future — the threshold above which the Durbin amendment caps debit interchange revenue.

That is a different calculation, and a rational one. For a business whose revenue comes largely from card interchange, crossing $10bn means giving up a substantial share of it. For SoFi, whose revenue comes from a lending spread, the threshold is irrelevant and scale is the point.

Which is the useful lesson in the ranking. There is no single fintech-becomes-a-bank strategy. There is a choice between earning on payments, which argues for staying small, and earning on a spread, which argues for getting as large as the deposit base will allow. SoFi made the second choice in 2022 and is now 47th on the list. Whether it belongs there will be settled by credit performance in the next downturn, not by the Summary of Deposits.

The $46.8bn deposit figure, the 47th-place ranking, the June 2024 comparison of $22.9bn, the Golden Pacific purchase price and the bank-count figures are from American Banker's report of 22 September 2026 on the FDIC's annual Summary of Deposits, which is published at fdic.gov and covers branch-level deposits at more than 4,200 insured institutions as of 30 June 2026. Consolidated deposits of $45.5bn, the $5.3bn quarterly increase, net interest margin of 5.98 per cent, the 156-basis-point funding gap and the $712.6m annualised saving, membership of 15.8 million, products of 24.4 million, GAAP net revenue of $1.218bn and net income of $156.6m are from SoFi Technologies' second-quarter 2026 earnings release of 29 July 2026, filed on Form 8-K. Advertised savings rates are from SoFi's published rate page, current as of 28 May 2026. Chime's agreement to acquire Stride Bank and its stated intention to hold assets below $10bn are as reported by American Banker in September 2026. The reconciliation of the bank-level and consolidated deposit figures, and the reading of the funding-cost gap, are our own; SoFi has not commented on the ranking.
