Shoppers spent $4.2 billion during Amazon.com’s Prime Day sale, up 33 percent from a year ago, according to estimates from Wedbush Securities analyst Michael Pachter.
The online retailer doesn’t disclose revenue from the 36-hour event that began Monday. Pachter based his estimate on information the company did release, including that it shipped more than 100 million products and that small and mid-sized businesses sold over $1 billion worth of goods in the first 24 hours.
