BURLINGAME, Calif.: Upstart Holdings, Inc. (NASDAQ: UPST), the leading artificial intelligence (AI) lending marketplace, today published its monthly origination volume for August 2026 and its latest Upstart Macro Index (UMI) reading. For historical data and more information, see upstart.com/volume and upstart.com/umi.

Monthly Origination Volume

September 3, 2026 UMI

The current UMI is 1.50, in line with the August 3, 2026 UMI. For reference, a UMI of 1.50 is approximately 50% above what Upstart would expect in a normal economy (a UMI of 1.0). UMI has remained above 1.0 since early 2022, reflecting a sustained period of elevated default risk relative to Upstart's long-run baseline, but remains below the series' peak of 1.68, reached in 2024.

About Upstart Origination Volume

“Originations” refers to Transaction Volume, Dollars, one of the key operating metrics Upstart reports in its quarterly and annual filings with the Securities and Exchange Commission (“SEC”). Transaction Volume, Dollars is defined as the total principal amount of loan originations (or committed amounts for HELOCs and draws for Cash Line) facilitated through Upstart’s marketplace during the periods presented.

“Origination days” represent the effective number of funding days in a month, based on a 24-hour funding window starting and ending at approximately 5:00 p.m. Eastern Time. Each business day counts as 1.0 day in Upstart’s calculation. Weekend days and bank holidays are weighted at 0.55 days to reflect lower application activity and are rolled forward to the next business day, when those loans are typically funded. If month-end falls on a weekend or bank holiday, originations from that period are attributed to the following month.

“Originations, Dollars per day” is calculated as total “Originations” divided by the number of “Origination days” in the applicable period. See upstart.com/volume for more information.

About UMI

The Upstart Macro Index (UMI) estimates the impact of the macroeconomy on credit losses for Upstart-powered loans. The UMI is a simplified representation, using Upstart's personal loan data, of the full suite of models and techniques Upstart has developed for assessing macroeconomic risk in lending. These may be used to different extents in the underwriting of each loan product, with personal loans generally using them most fully.

Upstart regularly recalibrates its underwriting model based on its latest read of macroeconomic conditions, and the published UMI is a close proxy for that read. Each new UMI reading is meant to give investors and capital partners a view into two things: (1) the macroeconomic risk assumptions currently factored into the pricing and approval of new loans, and (2) a directional sense of how Upstart's existing loans are performing - which depends largely on the actual risk level assumed when those loans were originally underwritten. See upstart.com/umi for more information.
