How to think about Prime Day 2026

Amazon officially confirmed this week that Prime Day 2026 is happening in June. No exact dates yet, but rumor is it will be a 4-day event starting June 23rd.

Amazon Prime Day is a big event in ecommerce: last year it generated $24.1 billion in US online sales, a 30% increase over 2024. Amazon will try to top that again, as they do every year.

How to think about Prime Day as a CPG brand

I have written about Prime Day prep in past editions, and I am not going to repeat the tactical checklist here. A lot is written out there about the operational playbook, and the things that matter every year still hold up: inventory readiness, account health, planning and execution of deals, advertising. What I want to focus on this time is how to think about Prime Day as a decision maker, because value of tactical execution is less if the strategic decisions behind it are off.

The most important thing I can tell you about Prime Day is that it is one event in a twelve-month calendar. It is not a standalone sprint. It is a moment inside a marathon, and how you approach it should be consistent with how you are running the rest of the year. Brands that treat Prime Day as an isolated sales spike tend to over-invest in short-term volume and under-invest in the things that make the rest of the year work: organic ranking momentum, steady but growing S&S enrollment, tweaking product pages for better conversions, refining advertising effectiveness.

With all the hoopla Amazon does to advertise Prime day to both customers and sellers it is tempting to think about it as ‘How do we maximize Prime Day sales’.

To me a better framing is: ‘How does Prime Day serve our goals for the year’. Because that’s a marathon type of question, and longevity on Amazon trumps short term sale spikes.

Start with the goal

Before you decide what promotions to run or how much budget to allocate, be clear about what you want Prime Day to accomplish for your business. The goal shapes everything downstream, and different goals lead to very different execution plans:
• Accelerate hero SKUs: if your top sellers have strong organic momentum, Prime Day is a chance to pour fuel on what is already working. Aggressive deals and ad spend focused on important keywords and right part of the funnel on products that are already converting well can push organic rankings to a level that carries weeks or months beyond the event.
• Acquire new customers: Prime Day brings a surge of shoppers who have never tried your brand. If customer acquisition is the goal, your promotion structure should prioritize trial-friendly offers, first-purchase incentives, i.e discounts.
• Move excess or aging inventory: monthly and long-term storage fees often outweigh the cost of discounting inventory to sell through. If you are sitting on aging inventory, Prime Day is a natural liquidation moment. The fee math usually makes this an easy decision.
• Launch a new product: the traffic surge gives new products more visibility than they would get in a normal week. If you have a product that is launch-ready, Prime Day can compress the timeline for building initial reviews and ranking signals.

These goals are not mutually exclusive, but they do compete for budget and attention. Pick one or two and build the plan around those.

Read your current numbers before you commit

Your goal for Prime Day should be informed by where your business actually is right now, not where you wish it were. A few questions worth asking before you lock in a plan:

Inventory

Do you have enough stock to support an aggressive push without risking a stockout in the weeks that follow? A great Prime Day followed by two weeks of out-of-stock on your hero SKU is a net negative. You don’t want to be more aggressive with ads during Prime Day if you run out of stock and lose ranking gained during Prime Day. Prime Day FBA and AWD inventory cutoff is June 5th, and May 27th respectively.

Margins

Margins: can your unit economics absorb the promotion you are planning? Prime Day deals, higher ad bids, and potential coupon stacking can compress margin to a point where volume growth is actually unprofitable. Run the numbers on your promotion structure against your current COGS and fees before you commit.

Here also keep in mind that Amazon recently changed how it calculates reference prices, effective mid-May. If you have been running promotions frequently, your Typical Price baseline may now be lower than you expect, which means the discount required to qualify for Prime Day deals will be deeper. Review your reference pricing in Seller Central before you commit to a deal structure, because the math may have shifted since the last time you checked.

Ad budget

Bids go up in every category during Prime Day, sometimes 100% + above normal levels. Your existing daily budget will run out earlier in the day, which means your campaigns go dark during peak shopping hours. Size the budget to the event, not to a normal week.

Ad campaigns of course need to align with Prime Day goals and SKUs you want to promote during the event. Input of PPC manager obviously is required here.

Category dynamics

In some CPG categories, Prime Day drives genuine trial and incremental volume. In others, it mostly pulls forward purchases that would have happened in the following weeks anyway. Some categories, like supplements typically run a lot more PD discounts than let’s say Grocery. Consider your competitive landscape, because you will be next to them in search results, and shoppers will be making comparisons based on what they see.

Define success before, measure after

Unless this is your first Prime Day (in that case success is to participate and document the results) define what success looks like before Prime Day starts, not after. If your goal was new customer acquisition, track repeat purchase rate , New to Brand customers, Subscribe and Save enrollment in the weeks that follow. If your goal was to accelerate a hero SKU, track organic keyword ranking and brand share movement in Brand Analytics for the month after.
The metrics that matter most for CPG brands on Prime Day are often the ones that take longer to show up:
• Subscribe and Save enrollment rate: the highest-leverage outcome for any CPG brand, because it converts a one-time Prime Day buyer into recurring revenue
• Repeat customer rate: available about a week after the event, this tells you whether Prime Day brought you customers or deal-seekers
• Brand share movement in Brand Analytics: did Prime Day shift your share of search and purchase in your key terms?
• Conversion rate during and after: a meaningful lift in conversion that sustains beyond the event tells you the momentum is real

Document what worked, what did not, and what surprised you. Spend some time browsing your category during the event and write down observations about competitor deals, creative approaches, and anything that sparks an idea. Your future self, and your team, will thank you for having this written down when you are planning for Fall Prime Big Deals Days in October and the next Prime Day after that.

Now what

June is close. If you have not started planning, you are not behind yet, but you will be soon. There is still time to send additional shipments to FBA. And the good news is that planning here does not mean a 20-page strategy document but running through the questions and goals above, and have functional experts (mostly catalog and PPC manager) on the same page.
