Online spending is expected to surge to $23.8 billion across U.S. retailers during a 96-hour Amazon Prime Day event this week, according to an Adobe Analytics forecast released on Monday, as shoppers seek strong discounts on back-to-school gear ranging from apparel to electronics.

MarketWatch polling suggests interest in Amazon’s super-sized Prime Day is muted. BofA analysts say the longer event suggests Amazon has more capacity to offer discounts, despite tariff fears.

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.
