Holiday update: Amazon commands 38 percent of the market following Cyber Weekend.

New data from Slice Intelligence shows 38 percent of holiday spending is with Amazon in the week following Cyber Weekend. Other merchants like BestBuy and Target have seen their share of the market decline slightly as spending tailed off after Cyber Monday. 

Electronics are the top category this holiday season as nearly one quarter of all online revenue being generated by tech purchases. Share of the category peaked Thanksgiving Day when 40 percent of all the dollars spent online were on electronics products.

While the electronics category is generating the most revenue, it isn't the fastest growing. Appliance sales are the fastest growing this holiday with sales up 56 percent compared to this time in 2015. Similarly, pet supply purchases are also over 50 percent larger this holiday season.
