Amazon has officially confirmed Prime Big Deal Days for October 6–7, 2026, and extended the U.S. seller deal submission deadline to September 22. This is a hard cutoff for participating in one of Amazon’s largest promotional events — if you’re planning to run deals during the event, you need to lock in your promotions before that date.
Key Dates & Eligibility
- Event dates: October 6–7, 2026
- Deal submission deadline (U.S. sellers): September 22, 2026
- Requirement: Eligible inventory with margins that can support promotional pricing
Planning Considerations for Sellers
- Inventory: Ensure you have sufficient stock of eligible ASINs to avoid stockouts during the event — Prime Big Deal Days typically see elevated volume.
- Margin math: Promotional deals reduce your per-unit profit. Model the discount depth Amazon is likely to request and confirm your costs allow a healthy margin at that price point.
- Submission readiness: Review your eligible catalog now so you can move quickly when you prepare submissions; last-minute errors can disqualify deals.
