The law firm of Kirby McInerney LLP announces that a class action lawsuit has been filed on behalf of investors who acquired Upstart Holdings, Inc. (“Upstart” or the “Company”) (NASDAQ:UPST) securities during the period of May 14, 2025 through November 4, 2025, inclusive (“the Class Period”).
The lawsuit alleges that (i) Model 22, the Company’s latest iteration of its AI model, frequently overreacted to negative macroeconomic signals in performing its risk-separation processes; (ii) accordingly, Model 22’s overall accuracy and propensity to increase loan approval rates was overstated; and (iii) Model 22’s overly conservative assessment of credit and macroeconomic conditions was having a significant negative impact on Upstart’s revenue results, rendering the Company's previously issued FY 2025 revenue guidance unreliable and/or unrealistic.
On November 5, 2025, Upstart disclosed that it missed third-quarter expectations and blamed the disappointing results on Model 22, which they revealed had “overreact[ed]” to macroeconomic signals in the quarter, reducing borrower approvals and conversion rates. The Company also acknowledged that they had “knowingly” calibrated their AI model to be “more conservative on the credit side in earlier parts of the quarter”, and that the negative impacts of Model 22’s “overresponsive[ness]” to macroeconomic signals in the quarter would continue to negatively impact revenues in Q4 2025, resulting in Upstart negatively revising FY 2025 financial guidance. On this news, the price of Upstart shares declined by $4.49 per share, or approximately 9.7%, from $46.24 per share on November 4, 2025 to close at $41.75 on November 5, 2025.
