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.

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.

Amazon Prime Day is usually met with competing sales from other retailers, and this year is no different. Walmart’s summer sale is back this year, competing with Prime Day and running for an extra two days.
