Upstart Holdings (UPST) Could Be 29% Undervalued On UMI Reading Of 1.50

Why Upstart Holdings’ latest UMI reading matters for investors

Upstart Holdings (UPST) has released its August 2026 loan origination figures alongside an updated Upstart Macro Index, or UMI, reading of 1.50, signaling default risk above the company’s long run baseline.

For Upstart Holdings, the latest UMI reading comes against a weak share price backdrop, with the stock closing at US$28.52 and recording a year-to-date share price decline of 37.78%, alongside a 1-year total shareholder return decline of 56.70%. This points to fading momentum despite the modest 1-day share price gain of 1.24% as investors digest higher perceived default risk and its implications for growth and valuation.

For Upstart Holdings, the sharp share price decline alongside improving revenue and net income raises a simple question: Are investors reassessing the fundamentals, or has sentiment moved further than the business justifies, given current valuation markers ahead?

Most Popular Narrative: 28.9% Undervalued

Based on the most followed narrative, Upstart Holdings’ fair value of $40.13 sits well above the last close at $28.52, which frames the current debate around the stock.

The implementation of Model 19, featuring the Payment Transition Model (PTM), has improved underwriting accuracy, which is likely to enhance loan approval rates and reduce default risks, positively impacting revenue and net margins.

Want to understand why this narrative still points to upside despite a weak share price chart and a UMI at 1.50? The story leans heavily on faster top line expansion, fatter margins over time, and a future earnings profile that looks very different to today. Curious which specific revenue and profit assumptions sit underneath that $40.13 fair value figure.

Using an 8.91% discount rate, the narrative aggregates analyst expectations on future revenue growth, profitability and valuation multiples into a single fair value anchor. It also reflects model updates where higher projected growth is tempered by lower assumed profit margins and a reduced future P/E, which together still support a fair value above the current share price. Investors weighing the latest UMI reading against this narrative may want to focus on how sensitive those assumptions are to default trends and funding conditions over the next few years.

Result: Fair Value of $40.13 (UNDERVALUED)
