This Cyber Monday may not be the first holiday shopping occasion, but it is looking like it will be a record breaker.

Software company Adobe is predicting that Cyber Monday will break $3 billion in sales for the first time ever this year, with mobile devices expected to drive the majority of shopping traffic also for the first time.

Adobe has predicted that mobile users will account for 51 percent of shopping traffic, and that this year shoppers will be more likely to find discounts through display ads and social media. Just under 30 percent of purchases are expected to be made via mobile devices, with iOS devices driving 22 percent of sales. Android devices are expected to account for seven percent of sales. Apple Pay is expected to account for three percent to four percent of sales revenue where the mobile payment option is available.

A total of $3 billion in predicted sales will represent a 12 percent year over year growth for Cyber Monday earnings.

According to Adobe, Cyber Monday’s online sales figures are expected to trump those from Thanksgiving Day and Black Friday, which totaled $1.73 billion and $2.74 billion, respectively.

Adobe’s figures from last week show that mobile shopping continued to grow on Thanksgiving and Black Friday, accounting for more than a third of sales.

Mobile devices – particularly iPhone and iPads – played a prominent role in driving online sales, Adobe said. On Thanksgiving Day, mobile traffic surpassed desktop for the first time with 57 percent of visits (43 percent via smartphones) and drove 37 percent of online sales (22 percent via smartphones), for a total of $639 million in sales.

“US consumers have turned into digital shopping ninjas this holiday season as retailers continue to adjust to a huge influx of smartphone shoppers,” said Adobe Digital Index principal analyst Tamara Gaffney. “Heading into Cyber Monday, online only retailers will take center stage and we are still calling for Cyber Monday to be the largest online day of the year, breaking the $3 billion mark and representing 12 percent YoY growth.”

Adobe’s Thanksgiving and Black Friday report is based on aggregated and anonymous data from visits to 4,500 websites and measurements from 80 percent of all online transactions from the top 100 retailers in the United States.
