Amazon’s long-held competitive advantage in advertising has consistently stemmed from its unparalleled access to proprietary data. This closed ecosystem, rich with purchase intent, browsing behavior, and crucial commerce signals, offers a depth of insight that few other platforms can replicate. Two significant announcements in May 2026 have not only solidified this advantage but have strategically expanded its reach in complementary directions, fundamentally reshaping Amazon’s Connected TV (CTV) advertising proposition. These moves, one pushing Amazon’s data outward into unowned inventory and the other drawing entirely new audience segments inward, have collectively made Amazon’s CTV offering the most addressable it has ever been.
Expanding Reach: Amazon Audiences Debut on Netflix
In a landmark development for the digital advertising landscape, Amazon rolled out the capability to apply its powerful Amazon Audiences to Netflix inventory. Initially launched in the US on April 13, 2026, this integration expanded to EMEA markets, including the UK, on May 18, 2026, making it immediately accessible to advertisers in these regions.
Amazon Audiences represent a sophisticated fusion of data points drawn from across the Amazon ecosystem. This includes granular shopping behavior, detailed browsing patterns, and valuable streaming signals. Amazon estimates the scale of this data to be in the trillions of data points, with an identity matching capability that reportedly covers approximately 90% of US households. For advertisers, this translates into the unprecedented ability to reach Netflix viewers based on their explicit purchase history, browsing activities, and demonstrated commercial intent – all within inventory that lies entirely outside Amazon’s owned properties. This level of granular commerce-driven targeting on third-party CTV inventory was simply not feasible twelve months prior.
The strategic significance of integrating with Netflix cannot be overstated. Netflix represents a highly coveted CTV inventory due to its inherent characteristics: it commands high viewer attention, offers a premium viewing environment, and delivers content at a genuine, large-scale viewership level. Crucially, this premium inventory was previously inaccessible to Amazon’s deep commerce data layer. The ability for an advertiser to identify a consumer actively searching for, for instance, running shoes on Amazon and then retarget them on Netflix with the same intent signals represents a substantial enhancement of the Amazon Demand-Side Platform’s (DSP) capabilities.
The Measurement Evolution: Closing the Loop
While the targeting advancements are undeniably compelling, it is the evolution in measurement capabilities that truly transforms the advertising argument. Amazon DSP has historically enjoyed a structural advantage in attribution. When brands leverage Amazon’s commerce data to target individuals exhibiting relevant behaviors, and those individuals subsequently make a purchase on Amazon, the entire customer journey is seamlessly traceable within a single ecosystem – from initial signal and ad exposure to the final purchase.
The advent of direct purchasing through television screens, while still nascent and scaling, introduces a new dimension. The customer journey becomes longer and less direct. However, Amazon Marketing Cloud (AMC) is engineered to bridge this gap, connecting CTV impressions to measurable in-Amazon retail outcomes such as product page views, add-to-cart events, and completed purchases.
For Netflix inventory, this closed-loop measurement system is not yet fully realized. Impression-level data from Netflix does not currently flow directly into AMC. However, industry observers widely believe this integration is on the product roadmap. Should this materialize, it would extend the powerful closed-loop measurement paradigm, previously confined to Amazon’s owned inventory, to encompass Netflix.
It is imperative for advertisers to understand this nuance when planning Netflix buys. While the targeting proposition – leveraging Amazon’s rich commerce data to connect with the right audience on a premium streaming platform – is robust and stands independently, the closed-loop measurement back to Amazon retail outcomes is not yet available. Nevertheless, the potential is undeniably exciting.
Bringing New Audiences In: LinkedIn Integration on Amazon DSP
In a parallel yet distinct strategic move, Amazon DSP announced on May 7, 2026, its integration with LinkedIn’s professional data, further bolstering its CTV buying stack. This integration allows advertisers to target LinkedIn’s expansive member base of over one billion individuals. The targeting capabilities include granular professional attributes such as job role, seniority level, and industry sector – signals that have historically lacked a viable, high-scale route into streaming inventory. This functionality is currently live in the US, with no confirmed UK launch date at present.
This LinkedIn integration represents a different strategic thrust compared to the Netflix announcement. While the Netflix move extends Amazon’s existing data outward into new inventory, the LinkedIn integration effectively brings a previously inaccessible audience type into Amazon’s ecosystem.
Targeting the Professional Elite on the Big Screen
Senior B2B professionals have long presented a formidable challenge for programmatic advertising at scale, particularly within premium environments. LinkedIn possesses the definitive identity data for this demographic. Until now, credible and high-scale routes into premium CTV inventory for these audiences have been limited. Amazon DSP is now poised to become that critical conduit. For B2B advertisers, this integration signifies the ability to execute professional identity targeting directly on the big screen, within high-attention viewing environments, without resorting to imprecise job-function proxies derived from third-party signals. The anticipated arrival of this capability in the UK promises to unlock a new and previously non-existent channel category for B2B buyers.
Navigating the Nuances: Limitations and Considerations
While the advancements are profound, it is important to acknowledge the limitations and scope them appropriately against specific advertising objectives. For brands that do not conduct sales directly on Amazon, the measurement case, while still valuable, is inherently less robust than for those that do. The coveted closed-loop measurement relies on Amazon’s proprietary purchase data. In its absence, advertisers are relegated to more traditional attribution methods, such as third-party tracking, conversion APIs, and clean room integrations. While these tools are effective, they do not offer the same integrated, end-to-end visibility as Amazon’s native system. Therefore, it is crucial for brands to carefully assess their specific category and sales environment before positioning AMC measurement as the primary rationale for their Amazon DSP buys.
This caveat also applies to the Netflix integration. The attribution story for Netflix inventory currently sits outside the direct AMC loop. The compelling case for advertising on Netflix via Amazon DSP rests firmly on the precision of its targeting capabilities and the premium quality of the viewing environment, rather than on closed-loop measurement of Amazon retail outcomes. Nonetheless, this remains a very persuasive proposition for advertisers.
The LinkedIn data layer, upon its eventual launch in the UK, will further enhance the argument for advertisers whose sales are not directly tied to Amazon. The ability to target professionals based on their identity on premium streaming inventory has historically been unavailable at a meaningful scale. CTV, by default, often skews towards being a predominantly B2C channel. This paradigm shift is set to occur with the integration of LinkedIn’s data into Amazon DSP for UK audiences, particularly benefiting advertisers seeking to reach senior decision-makers at scale.
The Synergistic Impact: A Doubled Data Advantage
The combined effect of these two strategic initiatives significantly amplifies Amazon’s already formidable data-driven advertising proposition. The Netflix announcement effectively extends Amazon’s most potent targeting data into the most premium CTV environment it has ever accessed. This enables broad awareness campaigns, built upon genuine commerce intent, to be executed within environments that capture high viewer attention. Concurrently, the LinkedIn integration opens up CTV to previously unreachable audiences at scale, ushering in a new category of buyer with access to premium streaming inventory and precise targeting.
The growth trajectory of CTV viewership is undeniable. In the UK, streaming accounted for 38% of total TV-set viewing in 2025, according to BARB, with the gap to live TV’s 45% rapidly narrowing, especially among younger demographics (16-34s). In the US, programmatic CTV is already a substantial $37 billion market, projected to grow by 14% year-on-year, as reported by eMarketer. The UK market, valued at £2.31 billion in 2026, is experiencing a similar upward trend with a 15% growth rate, according to IAB UK. This is not merely a channel in transition; it is a fully established and rapidly expanding media landscape. Amazon, through these strategic integrations, has equipped its buyers with the most advanced and powerful tools for navigating this dynamic environment.
Future Watch: Key Developments on the Horizon
Industry watchers are keenly observing the practical implementation and long-term impact of these integrations. Early results from running Amazon Audiences on Netflix inventory since the EMEA launch have been encouraging in terms of scale. The critical next step involves rigorous stress-testing of the AMC measurement loop in practice. This includes validating the connection between Netflix impressions and in-Amazon purchase outcomes, and confirming that the data delivered matches the promised capabilities. Comprehensive findings from these evaluations are anticipated to be shared.
The LinkedIn layer, once a UK launch date is confirmed, will represent a significant opportunity that warrants swift action. The window of time before this becomes a commonplace offering in the market is likely to be relatively short, making early adoption a potential strategic advantage.
The Bottom Line: Audience Infrastructure as the New Benchmark
As 2026 progresses, the fundamental question for advertisers is no longer whether to invest in CTV, as most brands have already established a presence in this space. The more pertinent and challenging question revolves around the audience infrastructure underpinning these CTV buys. The critical differentiator will be whether this infrastructure connects directly to measurable outcomes or merely approximates them. Amazon’s recent strategic moves have significantly raised the bar, offering a more direct and data-rich pathway to demonstrable results within the burgeoning CTV landscape.
