SoFi vs Upstart: Which fintech stock is the better long-term buy after 37% plunge?

SoFi Technologies and Upstart, two fintech stocks, have each fallen approximately 37% to 38% in 2026 amid market volatility and economic uncertainty. SoFi faces scrutiny after short-seller Muddy Waters released a critical report alleging financial engineering and inflated profits, claims the company denies and plans to contest legally. CEO Anthony Noto subsequently purchased $500,000 worth of shares. Despite this controversy, SoFi posted strong fundamentals with 38% adjusted revenue growth in 2025 and a projected 30% increase in 2026. Its customer base has expanded 161% over three years to 13.7 million members, and adjusted net income jumped 112% last year. Upstart operates an AI-powered lending platform that analyses over 2,500 variables for credit risk assessment, bypassing traditional FICO scoring and serving more than 100 lending partners.

ROSEN, NATIONAL TRIAL ATTORNEYS, encourages Upstart Holdings, Inc. investors to secure counsel before important deadline in Securities Class Action - UPST. Foto: adobe.stock.com New York, New York-(Newsfile Corp. - April 10, 2026) - WHY: Rosen Law Firm, a global investor rights law firm, announces a class action lawsuit on behalf of purchasers of securities of Upstart Holdings, Inc. (NASDAQ: UPST) between May 14, 2025 and November 4, 2025, inclusive (the "Class Period"). A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than June 8, 2026. SO WHAT: If you purchased Upstart securities during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement. WHAT TO DO NEXT: To join the Upstart class action, go to https://rosenlegal.com/submit-form/?case_id=58653 or call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected] for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than June 8, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved, at that time, the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers. DETAILS OF THE CASE: According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that: (1) Model 22 frequently overreacted to negative macroeconomic signals in performing its risk-separation processes; (2) accordingly, Model 22's overall accuracy and propensity to increase loan approval rates was overstated; (3) Model 22's overly conservative assessment of credit and macroeconomic conditions was having a significant negative impact on Upstart's revenue results, rendering Upstart's previously issued full year 2025 revenue guidance unreliable and/or unrealistic; and (4) as a result, defendants' public statements were materially false and misleading at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages. To join the Upstart class action, go to https://rosenlegal.com/submit-form/?case_id=58653 or call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected] for information on the class action. No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.

Upstart sued by investors over AI model that 'overreacted' to economic signals

A class of investors has sued fintech Upstart and several executives, alleging they made false statements about the company's AI model and business prospects between May and November 2025. The lawsuit, filed in the US District Court for the Northern District of California, claims executives misrepresented the accuracy of Model 22, which debuted in May 2025. After twice raising revenue projections to $1.055 billion based on the model's purported performance, Upstart missed its third-quarter estimate in November and slashed its full-year forecast to $1.035 billion. Executives then acknowledged the AI model had "overreacted" to macroeconomic signals, reducing borrower approvals. Upstart's stock fell 9.71% the following day. The investors noted that during this period, three executives sold shares worth a combined $15 million.
