Prime Day is getting a four-day stretch this year, but don’t let the extra promo time fool you—Amazon is still playing its favorite game: “hurry up and prep… but we’re not telling you the date.” Amazon Prime Day 2025 Deadlines are here.
What we do know is this: if you want your products Prime badge-ready (and shelf-ready), Amazon wants your inventory in by June. And not just in spirit—we’re talking cartons, labels, inbound shipping plans—the whole fulfillment love language.
The Clock Is Ticking (Even If You Don’t Know the Date Yet)
Amazon hasn’t announced exactly when Prime Day will land, but it’s a safe bet we’re looking at mid-July. That means sellers have to prep like they’re racing a ticking clock that refuses to tell time.
Here’s the breakdown of Amazon Prime Day 2025 Deadlines:
- May 23 – Last call for Lightning Deals and Prime-Exclusive Best Deals
- June 9 – Inventory due if you selected minimal shipment splits
- June 18 – Inventory due if you chose Amazon-optimized shipment splits
- Using Amazon’s Partnered Carrier? Your goods better be ready for pickup 14 days before those deadlines
FBM Sellers, You’re Not Forgotten… Just Left Guessing
If you’re fulfilling orders yourself, there’s still no confirmed Prime Day date, which makes staffing up a little tricky. But planning for a mid-July spike isn’t a bad move. If your team’s got flexible arms (and schedules), now’s the time to stretch.
The Real Prime Day Work Happens Behind the Scenes
Running deals is only half the equation. The rest is about logistics. Getting your inventory in on time, avoiding stockouts, and making sure your warehouse isn’t doing the panic shuffle come July.
Things you can do right now (without needing a crystal ball):
- Audit your bestsellers – What’s moving fast? What’s low? What’s got Prime potential?
- Build your FBA shipments now – Even if you’re still finalizing promos, start prepping boxes.
- Tighten up your multichannel flow – If you’re selling on Amazon and Shopify and elsewhere, now’s not the time for order chaos.
