Short seller Muddy Waters Research announced a short position in SoFi Technologies on Tuesday, accusing the $24 billion fintech company of inflating its financial results through aggressive accounting practices and at least $312 million in unrecorded debt. SoFi shares dropped more than 4% intraday before recovering to close down 1.3% at $17.37.
In a report published on its website, Muddy Waters called SoFi “a financial engineering treadmill, not a healthily growing origination business.” The firm, founded by activist short seller Carson Block, alleged that SoFi shareholders face constant dilution so management can hit bonus targets through questionable loan valuations and off-balance-sheet structures that disguise borrowings as revenue.
What Muddy Waters Claims About SoFi’s Financials
The most striking allegation involves SoFi’s personal loan charge-off rate. Muddy Waters calculates the actual rate at approximately 6.1%, more than double the 2.89% the company reports publicly. The short seller claims SoFi manipulates this metric by disposing of loans before they reach charge-off status and parking defaulted loans in unconsolidated entities.
The report also targets SoFi’s reported EBITDA of $1.054 billion, alleging it is inflated by roughly $950 million. According to Muddy Waters, that inflation comes from manipulated charge-off rates, subsidized seller-financed sales, unrecorded borrowings, an off-balance-sheet lending structure that books borrowing proceeds as fee income, and capitalized marketing expenses excluded from the headline metric.
Muddy Waters further claims that SoFi’s student loan business exists primarily “to generate fair value gains for management bonuses, not for strategic or economic reasons.” The report also alleges that SoFi management has locked in $58 million through instruments economically equivalent to stock sales while publicly claiming not to have sold shares.
SoFi Fires Back and CEO Puts His Own Money on the Line
SoFi wasted no time responding. The company called the report “factually inaccurate and misleading,” saying the allegations reflect “a fundamental lack of understanding” of its financial statements and business model in the competitive fintech landscape. SoFi said it may pursue legal action against Muddy Waters and highlighted that the short seller disclosed plans to profit from short positions tied to the report’s publication.
The company pointed to its regulatory oversight as evidence of financial integrity. SoFi operates as a bank holding company supervised by the Federal Reserve, with a nationally chartered bank regulated by the Office of the Comptroller of the Currency. Its financial disclosures comply with U.S. GAAP and SEC regulations.
After the market closed, CEO Anthony Noto bought 28,900 shares at an average price of $17.32, putting roughly $500,000 of his own money into the stock. SoFi shares rose 1% in after-hours trading on the news of the insider purchase.
Why This Matters for the Broader Fintech Market
SoFi has been one of the more prominent fintech success stories in recent years. Founded in 2011 as a student loan refinancing platform, the company obtained a bank charter in 2022 and has since grown into a one-stop digital financial services provider offering lending, investing, banking, and insurance products. Total deposits reached $37.5 billion, and the company recently announced a new Mastercard stablecoin deal alongside record profits.
The timing of the Muddy Waters report adds another layer of complexity. Fintech companies that rely on fair-value accounting and off-balance-sheet structures have faced growing scrutiny from regulators and investors alike. If the allegations carry weight, they could prompt wider examination of how digital lenders report loan performance and structure their balance sheets. If they do not, the episode still underscores the vulnerability of high-growth fintech stocks to short seller campaigns that can move markets in hours.
The full Muddy Waters report is available on the firm’s website. For now, the market will be watching whether SoFi follows through on its legal threats and whether its next earnings report addresses the specific metrics the short seller has challenged.
