Analysts at Adobe expect consumers will have spent up to $13.5 billion by the end of Cyber ​​Monday – marking the biggest online shopping day ever.

According to Adobe Analytics, it would surpass the record set just days earlier on Black Friday, when shoppers spent a record $10.8 billion online.

The calculations are based in part on spending tracked through early Monday evening. As of 6:30 p.m. ET, consumers had already spent about $8.7 billion, according to Adobe.

And it wasn’t even peak shopping time yet.

Peak online spending was expected between 8 p.m. and 10 p.m. ET. Adobe estimates that consumers would spend about $15.7 million per minute.

“Although early competitive discounts led to record spending on Thanksgiving and Black Friday, many consumers still consider Cyber ​​Monday the best day to get the best deals of the season,” said Vivek Pandya, senior analyst at Adobe Digital Insights.

“The day started well,” he said, “and with spending expected to increase in the evening hours, Adobe expects Cyber ​​Monday to retain its place as the biggest e-commerce day of the year.”

Cyber ​​Monday spending trends

Must-have items driving shoppers to fill their virtual shopping carts on Cyber ​​Monday include: Bluetooth headphones and speakers, computers and laptops, electric scooters and bikes, card and board games, gaming consoles and video games, stuffed animals and dolls , skin care products, clothing, gift cards, jewelry, smartwatches, patio heaters and televisions.

And many people bought these coveted items via their smartphones.

Although people typically shop from their work computers throughout the weekday, driving desktop-based sales, shoppers are becoming more comfortable with smaller screens, Adobe said.

This led to an increase in purchases on mobile devices.

On Cyber ​​Monday, 54.8% of daytime and afternoon online sales were made through a mobile device, accounting for $4.76 billion in sales. This corresponds to an increase of 9.6% since 2023.

Another notable trend this year is the increase in pay-later, Adobe noted.

“Buy now, pay later” options accounted for about $1 billion in spending on Cyber ​​Monday, Adobe reported. A survey found that most BNPL purchases were electronics, clothing, video games and groceries.

Two big influencers in online shopping this year have been social media influencers – whose content is seven times more effective at converting sales than social media posts alone – and chatbot recommendations, which consumers are increasingly turning to for product recommendations and as a source for offers, according to Adobe.

Online spending during Cyber ​​Week (the five-day period including Thanksgiving, Black Friday and Cyber ​​Monday) is expected to reach $40.6 billion, up 7% from 2023.

This represents 16.9% of expected spending for the entire holiday season in 2024.
