The Adobe Analytics report predicts spending on Cyber Monday to rise 5.2 per cent as cash-strapped punters seek to save cash before Christmas.
Adobe Analytics, which measures e-commerce by analyzing transactions at websites, has access to data covering purchases at 85 per cent of the top 100 internet retailers in the United States.
Cyber Monday sales fell 1.4 per cent last year as retailers spread out promotional deals across weeks from as early as October to better manage inventories amid widespread product shortages.
Most supplies though expect a return to big spending because users have been sitting on their cash because of rising inflation.
Mastercard Chief U.S. Economist Michelle Meyer said: "With holiday promotions kicking off long before the Thanksgiving weekend, consumers have been shopping strategically for the season's best deals."
US shoppers spent $9.12 billion online on Black Friday, according to Adobe Analytics. However, with sporadic rain in some parts of the country, brick-and-mortar stores and malls saw less humans in the street.
