What makes Amazon unique as an advertising platform has always been its data: a closed ecosystem of purchase intent, browsing behavior, and commerce signals that no other player in the market can fully replicate. Two announcements in May 2026 made that advantage even stronger, and they did it in opposite directions at the same time.
One move sends Amazon data to inventory that doesn’t belong to you. Another is bringing in a new type of audience from the outside. Together they make amazons CTV proposition the most responsive.
Data Out: Amazon’s Audience on Netflix
On April 13, Amazon introduced the ability to use Amazon’s audience to list Netflix in the US. EMEA followed on 18 May, making this live for UK advertisers now.
Amazon’s audience draws on purchasing behavior, browsing patterns, and streaming signals from the Amazon ecosystem. Amazon puts the estimate at billions of data points, with ownership matching saying it covers 90% of US households. Consumers can reach Netflix viewers based on what they’ve bought, browsed, and shown ad-hoc, in an inventory that resides outside of Amazon-owned properties. These brands have not been on CTV’s third-party list for the past twelve months.
Netflix isn’t just CTV’s inventory. It’s a high attention, premium environment, large screen viewing at a true scale, and was previously unattainable through Amazon’s commercial data layer. The ability to find a consumer buying running shoes on Amazon and reach them on Netflix using the same intent signals is a logical extension of what DSP can do.
Targeting is interesting. Measurement is what changes the argument.
Amazon DSP has always had a structural advantage in rendering. When a brand uses Amazon commerce data to reach someone who is actively browsing or shopping in the right category, and that person later makes a purchase on Amazon, the full journey is traceable: signal, exposure, purchase, all in one ecosystem. Direct TV shopping is new, and still growing – and the future nature and scale of this is currently unknown. The loop is longer, the path less direct. But Amazon Marketing Cloud connects CTV impressions to Amazon sales results: product page views, add-to-cart events, purchases. If this functionality is available across Netflix and other 3P CTV inventory (which we believe is on the way) the closed loop that was previously only available on Amazon’s inventory will extend to Netflix.
For brands that sell on Amazon, that changes the way you think about CTV investments. Not just an access vehicle with a vague definition, but a trackable step on a measurable journey. You can understand how Netflix’s perception actually contributed to the drop in purchases, not nearly and not with a modeled attribute, but with modeled identity data. That’s a very different conversation to have about CTV’s budget.
Data in: LinkedIn to Amazon DSP
On May 7, Amazon DSP announced that it has integrated LinkedIn professional data into its CTV shopping stack. Marketers can now target LinkedIn’s billion-plus member base using signals like role, rank, and industry, attributes that have had no effective way to build a distribution list until now. Currently based in the US only, with no confirmed UK launch date.
This is a different type of movement. The Netflix announcement expands Amazon’s data out into a new asset. The LinkedIn integration brings a type of audience to Amazon’s ecosystem that wasn’t there before.
Senior B2B professionals have historically been one of the most difficult audiences to reach programmatically at scale, especially in leading geographies. LinkedIn has identity data. Until now there has been no reliable way for high-quality, high-quality CTV. Amazon DSP is the way. For B2B marketers, this is a professional identity directed to the big screen, in careful viewing areas, without relying on inefficient proxies created by third-party signals. If this capability reaches the UK, it opens up a channel category that has never meaningfully existed for B2B buyers before.
Where Argument has limitations
For products that don’t sell on Amazon, the valuation case is weak. The closed loop depends on Amazon’s purchase data. Without you, you’re back to third-party attribution, tags, conversion APIs and room integrations that are clean, useful but not quite as powerful. It is worth checking this carefully against your specific category and sales area before treating the AMC ratio as the main reason to buy.
LinkedIn’s platform, when it comes to the UK, will further expand the argument for advertisers who don’t rely on Amazon for sales. Professional ownership aimed at premium broadcast installations has historically been unavailable, and CTV tends to lean towards being more of a B2C channel by default. That changes when LinkedIn data reaches the UK audience through Amazon DSP, especially for marketers trying to reach top decision makers at a higher level.
What does this mean together
Amazon’s data play, already a very compelling differentiator in its advertising stack, has become powerful in two ways at once.
Netflix’s announcement makes CTV more relevant than ever to Amazon consumers. Extensive awareness campaigns that close the loop back to Amazon sales. LinkedIn’s announcement enables CTV to target an audience it previously could not reach at scale. A new type of buyer who gets access to premium inventory for streaming with real accuracy.
UK broadcast reached 38% of total TV viewing by 2025 per BARB, while live TV sits at 45% but the gap is narrowing fast, especially among 16-34s. US programmatic CTV is already a $37 billion market growing 14% year over year per eMarketer; IAB UK puts the UK market at £2.31 billion by 2026, up 15%. This is not a revolutionary station. It’s a channel that has arrived, and Amazon has just given its shoppers more advanced tools to navigate it.
What we are watching
We’ve been using Amazon Audiences on Netflix since the EMEA launch, and early results are encouraging. The next phase is to stress test AMC’s measurement loop in practice: connecting Netflix impressions to Amazon shopping results and making sure the data matches the promise. We will share what we find.
The LinkedIn platform, when we confirm the UK launch date, will be eligible to proceed immediately. The window before this becomes common practice is likely short.
Bottom line
The question for 2026 is not whether to buy CTV. Most brands already have a position on that. The tough question is what audience infrastructure sits beneath your purchase, and whether it connects to results or just moderates them.
