Adobe Analytics data revealed that strong deals across U.S. retailers on the first day of Amazon Prime Day prompted shoppers to trade up and purchase higher-ticket items.

U.S. consumers spent $7.9 billion at online stores on Tuesday, a 9.9% increase from the comparable day last year.

The first four-day-long Prime Day sale, is expected to generate as much spending as two Black Fridays, Adobe reports today, with AI tools and influencers driving growth.
