Amazon’s unparalleled advantage in the advertising landscape has long been rooted in its proprietary data – a closed ecosystem encompassing purchase intent, browsing behavior, and granular commerce signals that no other platform can fully replicate. Two significant announcements made in May 2026 have dramatically amplified this advantage, each operating in a distinct yet complementary direction. These strategic moves not only extend Amazon’s influential data into previously inaccessible inventory but also introduce entirely new audience segments into its advertising fold, collectively rendering Amazon’s Connected TV (CTV) proposition more addressable than ever before.
The first, a landmark expansion, sees Amazon’s rich data venturing beyond its own digital properties to enrich inventory it does not own. The second, a strategic influx, ushers in a novel audience type from an external powerhouse. Together, these developments signify a profound evolution in how advertisers can leverage Amazon’s capabilities to connect with consumers across a wider spectrum of digital experiences.
Data Expansion: Amazon Audiences Unlocking Netflix’s Premium Inventory
On April 13, 2026, Amazon initiated a groundbreaking capability, enabling advertisers to apply Amazon Audiences to Netflix inventory within the United States. This rollout was subsequently extended to the EMEA region on May 18, making the powerful targeting tools immediately available to UK advertisers.
Amazon Audiences represents a sophisticated aggregation of consumer insights derived from across the entire Amazon ecosystem. This includes detailed shopping behaviors, intricate browsing patterns, and nuanced streaming signals. Amazon estimates the sheer scale of this data to be in the trillions of data points, with identity matching capabilities that reportedly cover approximately 90% of U.S. households. This empowers advertisers to precisely target Netflix viewers based on their demonstrated purchase history, browsing activities, and explicit commercial intent signals, all within a streaming environment that exists entirely outside of Amazon’s owned platforms. Crucially, these sophisticated commerce-derived signals were not available for use on third-party CTV inventory just twelve months prior to these announcements.
Netflix is not merely another piece of CTV inventory; it represents a highly coveted environment characterized by high viewer attention, premium content, and large-screen viewing experiences at a significant scale. Historically, this premium environment remained largely out of reach for Amazon’s proprietary commerce data layer. The ability to identify a consumer actively researching or purchasing running shoes on Amazon and then effectively reach that same individual on Netflix, utilizing the identical purchase intent signals, constitutes a meaningful and impactful extension of Amazon’s Demand-Side Platform (DSP) capabilities.
The Measurement Revolution: Bridging the Gap Between Intent and Outcome
While the targeting capabilities are undoubtedly compelling, it is the transformative impact on measurement that truly redefines the advertising argument. Amazon DSP has historically held a structural advantage in attribution. When a brand utilizes Amazon’s commerce data to reach an individual actively browsing or purchasing within a relevant product category, and that individual subsequently completes a purchase on Amazon, the entire consumer journey is meticulously traceable. This encompasses the initial signal, the ad exposure, and the final purchase, all contained within a single, unified ecosystem.
The advent of direct purchasing through the television is a nascent and still scaling development, with its future state and ultimate scale remaining largely unknown. The consumer journey in this context becomes longer and less direct. However, Amazon Marketing Cloud (AMC) is now instrumental in connecting CTV impressions to tangible in-Amazon retail outcomes, such as product page views, add-to-cart events, and ultimately, purchases.
For Netflix, this closed-loop measurement capability is not yet fully realized. Impression-level data from Netflix does not currently flow directly into AMC. However, industry observers anticipate this functionality to be a key part of Amazon’s future roadmap. Should this integration occur, the closed-loop measurement that was previously confined to Amazon’s owned inventory could be extended to encompass Netflix viewership, offering unprecedented visibility into the impact of CTV advertising.
This distinction is critical for advertisers when scoping Netflix buys. The targeting argument, leveraging Amazon’s rich commerce data to reach the right individual on a premium streaming platform, stands firmly on its own merits. However, the complete closed-loop measurement argument, as it currently exists, does not extend to Netflix inventory. Nevertheless, the prospect of such comprehensive measurement is generating significant excitement within the advertising community.
Data Influx: LinkedIn’s Professional Data Powers Amazon DSP
In a parallel but distinct strategic maneuver, Amazon DSP announced on May 7, 2026, its integration with LinkedIn’s professional data. This partnership allows advertisers to now target Amazon’s extensive CTV buying stack using granular professional attributes from LinkedIn’s colossal member base of over one billion individuals. These attributes include job role, seniority level, and industry sector – data points that previously lacked a viable and scalable route into streaming inventory. This integration is currently live in the United States, with no confirmed launch date for the UK market at present.
This LinkedIn integration represents a different order of strategic move compared to the Netflix announcement. While the Netflix partnership extends Amazon’s existing data outward into new inventory, the LinkedIn integration brings an entirely new and highly valuable audience type into Amazon’s advertising ecosystem, one that was previously underserved or inaccessible.
Senior B2B professionals have historically posed a significant challenge for programmatic advertising at scale, particularly within premium digital environments. LinkedIn possesses the definitive identity data for this demographic. Until this integration, credible and high-scale routes into premium CTV environments for this audience were limited. Amazon DSP now provides that critical pathway. For B2B advertisers, this signifies the ability to execute professional identity targeting directly on the big screen, within high-attention viewing environments, without resorting to broad job-function proxies derived from less precise third-party signals. When this capability becomes available in the UK, it will unlock a significant new channel category for B2B buyers that has not been effectively accessible before.
Navigating the Limitations: Measurement Nuances for Non-Amazon Sellers
It is important to acknowledge the limitations of these advancements, particularly for brands that do not directly sell their products on Amazon. For these businesses, the measurement case, while still strong in terms of targeting precision, is slightly different. The closed-loop attribution model is fundamentally dependent on Amazon’s purchase data. In the absence of direct Amazon sales, advertisers must rely on more traditional third-party attribution methods, ad tags, conversion APIs, and clean room integrations. While these tools remain valuable, they do not offer the same seamless, end-to-end visibility as Amazon’s internal attribution system. Advertisers should carefully consider their specific category and sales environment before making AMC measurement the primary rationale for their media buys.
This point 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 through Amazon DSP rests on the unparalleled targeting precision and the premium quality of the viewing environment, rather than on closed-loop measurement that directly ties back to Amazon sales outcomes. Nonetheless, this targeting precision alone represents a very compelling proposition.
The forthcoming LinkedIn data layer, once it reaches the UK market, will further enhance the argument for advertisers who do not rely on Amazon for their sales. Professional identity targeting on premium streaming inventory has historically been unavailable at any meaningful scale, and CTV often defaults to being a predominantly B2C channel. This paradigm is set to shift significantly as LinkedIn’s data becomes accessible to UK audiences via Amazon DSP, particularly for advertisers aiming to reach senior decision-makers with a high degree of precision.
The Synergistic Impact: A Unified Vision for CTV Dominance
The confluence of these two strategic moves solidifies and amplifies Amazon’s data-driven advantage, already the most potent differentiator in its advertising stack. The Netflix announcement strategically extends Amazon’s most powerful 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 high-attention viewing environments, offering a potent combination for brand building.
Concurrently, the LinkedIn integration dramatically enhances CTV’s addressability by enabling targeting against audiences that were previously out of reach at scale. This opens up a vast new segment of premium streaming inventory to precise targeting, catering to a whole new category of buyers, particularly within the B2B sector.
The broader context of CTV’s growth underscores the significance of these advancements. In the UK, streaming services accounted for 38% of total TV-set viewing in 2025, according to BARB data, rapidly closing the gap with live TV, which stood at 45%. This trend is particularly pronounced among younger demographics. In the United States, programmatic CTV has already emerged as a substantial market, valued at $37 billion and experiencing a robust 14% year-on-year growth, as reported by eMarketer. The IAB UK estimates the UK market to be worth £2.31 billion in 2026, projecting a 15% increase. This data clearly indicates that CTV is not merely a channel in transition; it has unequivocally arrived. Amazon, with these strategic enhancements, has equipped its advertisers with the most sophisticated and powerful tools available for navigating this rapidly evolving landscape.
Key Developments Under Watch
The industry is keenly observing the practical implementation and results of these new capabilities. Early performance data from the EMEA launch of Amazon Audiences on Netflix inventory has been encouraging, with early scale results meeting expectations. The next critical phase will involve rigorous stress-testing of the AMC measurement loop in practice. This will entail meticulously connecting Netflix impressions to in-Amazon purchase outcomes and validating that the data accurately reflects the promised attribution capabilities. Detailed findings from these tests are expected to be shared, providing crucial insights for the broader advertising community.
The LinkedIn data layer, once its UK launch date is confirmed, is expected to be a high-priority integration for many advertisers. The window of opportunity before this capability becomes a widely adopted standard practice is anticipated to be relatively short, making swift adoption a strategic imperative for those seeking to gain an early advantage.
The Bottom Line: Audience Infrastructure as the Deciding Factor
For the advertising landscape in 2026, the fundamental question is no longer whether to invest in CTV. For most brands, a strategic position on this channel has already been established. The more pertinent and complex question revolves around the audience infrastructure underpinning these CTV buys. Specifically, advertisers must assess whether their chosen infrastructure truly connects to measurable outcomes or merely approximates them. Amazon’s recent dual announcements have significantly bolstered the former, offering advertisers a more robust and data-rich foundation for their CTV strategies, whether their focus is on direct commerce sales or sophisticated professional targeting. The ability to leverage precise intent data on premium streaming platforms, coupled with the introduction of entirely new, high-value audience segments, fundamentally reshapes the potential of CTV advertising.
