Prime Big Deal Days performance and platform updates 👇
Record days across the board. 5 brands had their highest sales day ever on Amazon. One beat its previous best day by 45%, and another by 175%. Several more set their biggest days of 2026, including one brand that beat its entire 4-day June Prime Day total in just 2 days.
Growth without losing efficiency. Against last year’s event, ad sales across the agency rose 42%, ROAS improved, and cost per click fell 13%. Two of our record-setting brands stayed under a 10% TACoS.
Rank gains last beyond the event. One brand climbed to #2 in a highly competitive category. Another’s hero product reached its best rank ever, moving from a 90-day average of #86 to #23.
Some brands did it without deals. At least one brand set an all-time record with no promotions running, on strategy and visibility alone.
Platform updates in the last few weeks:
🔶 Walmart "Marty" officially live in accounts - your Al-powered advertising assistant, here to help you launch campaigns, get insights and find answers.
🔶 Out-of-Stock Protection is now generally available on Walmarts Display Auction: Ads now only show when the advertised product is in stock in-store or online, so spend on out-of-stock items stops without anyone having to pause campaigns.
🔶 Review Requests (beta): a new ad product that invites verified buyers to leave a review. You only pay when they leave a rating or review, which could matter for low-review launches.
🔶 Marketing Stream v2 + new Reporting API (v1) are now generally available: full ad data now lands in S3 automatically, and one report can combine ad products and accounts, with standardized metric names across Amazon Ads.
🔶 Inventory Management Unified APIs are now generally available: one programmatic way into DSP deals, publishers, supply and deal performance.
