Your competitors just told you how they'll behave in November. Were you paying attention?

Most retailers treat Prime Day as noise. It's actually a dress rehearsal for Black Friday—and one of the clearest reads on competitor behavior you'll get all year.

Every summer, Amazon hosts an event that generates billions in revenue, dominates headlines, and sends retail teams into reactive overdrive. Most retailers treat Prime Day as a distraction—something to manage around, respond to if necessary, and move on from once the noise dies down and trading returns to normal.

If that sounds familiar, it's worth reconsidering.

What Prime Day actually is—if you're paying attention—is a dry run for Black Friday conditions. Compressed demand, heightened price sensitivity, a consumer base actively scanning for the best deal across every channel. And while that's playing out, your competitors are making real pricing decisions under genuine commercial pressure—and those decisions are visible if you're paying attention.

The two signals that matter

There's a lot of noise in the retail calendar. The skill isn't collecting more of it—it's knowing which signals actually drive action.

How your competitors price. Watch what happens to a competitor's shelf price during Prime Day and you start to see how they make decisions. Did they move early and hold, or shift repeatedly across the event? Did they protect certain lines while discounting others? The pattern of those moves—not just the fact of them—tells you whether there's a pricing strategy behind the activity or whether someone is reacting to a dashboard and hoping for the best. That distinction doesn't change in November. If anything, it gets more pronounced.

What Amazon's bestseller rankings are actually telling you. During Prime Day, Amazon's category bestseller lists shift in real time and they're publicly visible. What rises to the top isn't just what Amazon is pushing—it's what consumers are actively choosing when they have options and intent. A product climbing the rankings is worth understanding: is it a traffic driver pulling people into a category, or does it suggest a line that's been sitting and needed a discount to move? That context shapes how you read your own category plan going into Q4.

The challenge isn't finding these signals—both are visible without needing special access or tools you don't already have. It's building the habit of reading them commercially, quickly, and routing what you learn to the people finalising autumn plans before those plans get locked. Most retailers do debrief Prime Day—but by the time learnings have been collated and shared, the window to act on them has already closed.

What competitors' Prime Day behavior is actually telling you

Watch how a competitor behaves during Prime Day and you're watching how they make decisions under pressure. What they actually do when they choose to compete.

A competitor who moves early, holds position for most of the event, and finishes where they started is a competitor who has modeled the trade-off in advance and is executing against a plan. They know their elasticity. They're not reacting—they're managing.

A competitor who shifts price repeatedly across the event, continually discounting as the days go on, is a competitor operating without that clarity. They're making it up as they go.

That distinction matters enormously for November. Black Friday is longer, more intense, and carries significantly more margin risk than Prime Day. Retailers who couldn't hold discipline over the summer won't find it in November—the pressure is greater and the cost of getting it wrong is higher. If you can read which competitor is which now, you can decide where to compete aggressively, where to hold, and where the opportunity to take share actually exists.

That's not a minor planning advantage. It's the difference between entering the most critical trading period of the year with a strategy versus entering it with hope.

What most businesses do with this (and what they should do instead)

The honest answer is: not enough, and not fast enough.

Prime Day learnings get collated. Sometimes they end up in a post-event review. Often that lands in early August, after holidays and handovers have diluted the urgency. By September, it's background context at best—something that shapes the mood in planning meetings but rarely changes the hard decisions.

The retailers who get more out of it are the ones treating Prime Day as the opening act of Q4 planning, not a footnote to it. They're connecting what they saw in the market over those few days to the inventory and pricing decisions that are about to get locked in for autumn, while there's still time to change something.

That's not complicated in principle. But it requires acting on what you learn while it's still relevant.

What the data from 100 retail leaders is already showing us

We've been speaking to 100 retail leaders across the United Kingdom (UK) about how their organizations actually make merchandising decisions—where the intelligence lives, how quickly it moves, and where it gets stuck.

The findings land in July. But even before that, a pattern has emerged clearly enough to share now. The retailers who are most confident going into Golden Quarter aren't the ones with the most data. They're the ones who have built the shortest path between signal and decision. They've reduced the time between something changing in the market and a response being authorized and executed.

And they've done it not by hiring more analysts, but by changing what their technology is responsible for. The monitoring, the pattern recognition, the scenario modeling—that authorized work now runs continuously, not periodically. Which means their commercial teams spend less time building the picture and more time acting on it.

That shift sounds incremental. The competitive effect of it is anything but.

The question worth sitting with

Pay attention during Prime Day. Your competitors will tell you, through their pricing decisions and their category performance, exactly how they intend to approach the most important trading period in retail.

The question isn't whether you'll see the signal. It's what you'll actually do with it.

If the honest answer is "not enough, not fast enough"—that's the conversation worth having.
