Cyber Monday is blowing out expectations.

This year's online shopping holiday is on track to become the largest U.S. online shopping day in history, according to data from Adobe Analytics.

As of this morning at 10 am ET, $840 million was spent online shopping, that marks a 16.9% year-over-year increase. Overall web traffic is higher 12% year-over-year.

"Cyber Monday is expected to make history again as the biggest U.S. online shopping day of all time, driving a billion dollars more than last year. As consumers make their way back to work, they are poised to be hitting the buy button all day, as most big discounts will end by midnight. A lot more of this will be happening on smartphones as well, where smoother buying experiences through auto-fill capabilities are helping drive the growth we see in mobile," said Tamara Gaffney, Strategic Insights Engagement Group Director, Adobe.
