It also said customers ordered over 180 million items over the five days starting with Thanksgiving through Cyber Monday.
Amazon did not say how many items it sold on Cyber Monday alone. It also did not release revenue generated over the holiday weekend, or any other data that could provide insight into how well its fourth quarter is going. We won't have a full sense of how Amazon performed this quarter until it reports earnings after the new year.
Investors are expected to closely watch the results of Amazon's holiday sales after the company delivered fourth quarter guidance that missed Wall Street expectations. In its third-quarter earnings report, Amazon said it expected revenue for the holiday season to range from $66.5 billion to $72.5 billion, below the consensus estimate of $73.79 billion.
The company also said Tuesday that small and medium-sized businesses worldwide grew sales over 20 percent on Black Friday year-over-year, but it did not provide specific figures.
