Prime Day 2026 is in the books, and the data is telling a more complicated story than "sales were up."
We pulled the numbers on what actually moved this year:
Sales performance by category — where growth was real vs. where it was inflated by discounting
Advertising costs — CPC and ACoS trends during peak vs. the rest of the year
Category winners and losers — which verticals outperformed, which underdelivered
We broke it all down in our Prime Day 2026 Results Report. No fluff, just the data sellers and brands need to make real decisions.

Here's the part that makes this year different: Amazon has confirmed its Holiday 2026 deal calendar and inventory deadlines and the first one lands soon. Submit your Prime Big Deal Days promotions by August 5 to lock in the $50 early-submission discount, and get inventory to Amazon's facilities by September 16 (Amazon-optimized shipment splits — the option most sellers use) to keep your Prime badge for the event.
That's less than a month away. This analysis gives you the data to plan for it with confidence instead of guesswork.
