Amazon’s ad revenue growth decelerates due to Prime Day tweaks
Amazon's Q3 ad revenue grew 12% YoY to $19.6B, down from 22% YoY last year. The deceleration was attributed to Prime Day timing changes and NBA streaming. Amazon's stock fell post-earnings, missing expectations. CEO Andy Jassy dismissed concerns about AI agents impacting ad revenue. Amazon forecasts high-teens ad growth in Q4, slower than last year's 22%.
