Amazon Prime Big Deal Days: The Return of the 2-Day Format
The two-day format is back – and that’s more commercially significant than it might appear.
This year’s four-day Prime Day created a flatter demand curve that was harder to read and harder to optimise around.
Budgets got spread thin, demand signals were less decisive, and the events that normally define peak event performance – the sharp open, the strong close – were diluted across four days.
Two days changes that dynamic, because shopper intent concentrates, demand spikes are sharper and the media performance data that comes out of it is cleaner and more useful as a benchmark.
And for brands with strong preparation in place, a compressed window is an advantage, not a constraint – because it rewards decisiveness over reactivity.
Our take
The brands that performed best in October will have been the ones who’ve already made their decisions – on promotional depth, budget deployment, content readiness and stock position – rather than the ones still optimising as the event opens.
There’s also a broader strategic case for treating Prime Big Deal Days seriously regardless of category: the data it generates on conversion, competitive share and media efficiency is some of the most useful you’ll get before Black Friday.
That means the brands that read it well going in will be the ones now better placed to act on it coming out…
Amazon DSP now connects to ChatGPT
Amazon’s programmatic reach just extended into conversational AI.
Amazon has announced a partnership with OpenAI enabling advertisers to expand their Amazon DSP campaigns with a conversational ad experience on ChatGPT, with select US advertisers currently testing the integration as part of a pilot.
This is a DSP-only development – it doesn’t affect Sponsored Products or Sponsored Brands – but the strategic direction it signals is significant.
Amazon is steadily building its DSP into a unified programmatic layer that reaches audiences well beyond its own platform, whether through Netflix, LinkedIn CTV or now ChatGPT. And this integration enables advertisers to engage with customers as they explore options, compare choices and make decisions within ChatGPT’s conversational environment.
Our take
This is a US pilot and UK timelines aren’t confirmed, but the trajectory is clear – Amazon’s retail media infrastructure is becoming the access point for a growing range of high-quality audience environments.
For brands already running DSP, understanding what those environments offer – and building the creative and targeting strategies to use them properly – is worth starting now rather than when they arrive.

Seller Assistant gets Persistent Memory and 24/7 Workflows
Amazon’s agentic AI is starting to act, not just advise…
Amazon has significantly expanded Seller Assistant, introducing persistent memory that retains context across pricing patterns, inventory cycles and growth goals, alongside new 24/7 automated workflows that monitor market conditions and execute routine tasks – with seller-defined guardrails and full audit trails.
The more commercially interesting development is the plugin launch, which brings Seller Assistant’s intelligence into third-party AI tools including Amazon Quick and Anthropic’s Claude, allowing external AI to access real-time Amazon data including listing contributions, inventory levels and sales analytics; and to act on the business directly, not just surface information.
With hundreds of thousands of active users and a 90% recommendation acceptance rate, Amazon’s signal is clear: agentic AI that acts on a seller’s behalf, not just with them, is the direction the platform is moving.
Our take
For established brands, this raises the bar on how Amazon operations are managed and what oversight looks like.
The efficiency gains are real, but so is the risk of accepting AI-generated recommendations without the commercial context to evaluate them properly.
And a team that can interrogate what the AI is recommending – and why – will use these tools far more effectively than a team that just that defaults to acceptance.
Germany joins the UK on Amazon Reference Pricing Rules
If you’re operating across EU markets, your pricing compliance picture just got more complex…
From 9 September 2026, Amazon Germany has updated its RRP validation requirements to match changes already in effect in the UK since June, with other EU marketplaces set to follow.
RRPs now need to be validated against 90 days of Featured Offer transaction data on Amazon, or evidence of the same price at another reputable retailer, with unsupported reference prices suppressed from listings.
For brands operating solely in the UK, this is a confirmation of rules already in place.
But for multi-market brands? It’s a flag that the same pricing discipline now needs to apply consistently across your European catalogue – and that promotional strategies relying on inflated reference prices are increasingly untenable at a platform level, not just in individual markets.
Our take
The brands most exposed here are those running promotional strategies that rely on resetting reference prices, or where RRP has drifted from actual transaction data across markets.
With EU rollout underway, now is the time to audit your reference pricing position across all active marketplaces, particularly heading into a promotional quarter where discount visibility directly affects conversion.
Seller Central just got a whole lot more ambitious
What Amazon’s new multichannel Seller Central tools signal about where the platform is heading…
Amazon has launched multichannel selling tools in Seller Central, connecting orders, listings, profitability and analytics across eBay, Shopify, TikTok and Walmart – alongside Amazon – in one single workspace.
The rollout is currently US-based, with UK and wider availability to follow.
The practical pitch is operational efficiency: instead of logging into four separate dashboards and reconciling data by hand at month end, brands see every order from every channel in one place, manage listings centrally and track profitability across all of them together.
But the more strategically interesting detail is in what Amazon explicitly says its ambition is: to become the single place where brands manage their entire business, not just their Amazon listings. That’s a significant statement of intent from a platform that many established brands have deliberately kept as one channel among several.
Our take
For brands already managing meaningful volume across multiple channels, this raises a question worth sitting with.
Amazon as a unified operating hub creates real efficiency, but it also means feeding more of your commercial data into Amazon’s infrastructure.
The brands best positioned to use this well will be the ones who have already defined what Amazon’s role is in their wider channel strategy, rather than letting a convenient dashboard make that decision for them.
The Bottom Line
Five updates, one consistent theme: Amazon is tightening the standards it applies to brands at every level: on pricing integrity, operational AI, media infrastructure and peak event execution.
Each of these is a signal to act on, and the brands best positioned going into Q4 are the ones treating them exactly like that as opposed to another development to monitor.
