Amazon’s unparalleled advantage in the advertising landscape has long been its proprietary data, a closed ecosystem rich with purchase intent, browsing behaviors, and commerce signals that competitors struggle to replicate. In May 2026, two significant announcements dramatically amplified this strength, expanding Amazon’s reach and audience capabilities in opposing yet complementary directions, solidifying its position as the most addressable Connected TV (CTV) advertising platform.
The first move strategically extended Amazon’s powerful audience data beyond its owned properties, integrating it into external inventory. Concurrently, the second initiative broadened Amazon’s addressable audience by incorporating a novel and highly valuable demographic from an entirely new source. Together, these developments represent a pivotal evolution in how brands can connect with consumers through the television screen.
Data Expansion: Amazon Audiences Unleashed on Netflix
On April 13, 2026, Amazon initiated a groundbreaking expansion by enabling advertisers to leverage Amazon Audiences on Netflix inventory within the United States. This capability subsequently rolled out to EMEA markets on May 18, making it immediately accessible to UK advertisers. This integration marks a significant departure, allowing Amazon’s rich behavioral data to inform ad targeting on a platform previously outside its direct data influence.
Amazon Audiences are meticulously curated from a vast spectrum of consumer activities across the Amazon ecosystem, encompassing shopping habits, browsing patterns, and streaming behaviors. Amazon reports its data encompasses trillions of data points, with identity matching capabilities that reportedly cover 90% of U.S. households. Advertisers can now target Netflix viewers based on their demonstrated purchase history, browsing interests, and expressed commercial intent, all within an advertising environment entirely independent of Amazon’s owned digital properties. This level of granular, commerce-driven targeting on third-party CTV inventory was virtually non-existent just twelve months prior.
The strategic significance of integrating with Netflix cannot be overstated. Netflix represents a highly desirable CTV inventory: it boasts high viewer attention, offers a premium viewing environment, and delivers large-scale reach on the big screen. Crucially, this premium inventory was previously inaccessible to Amazon’s powerful commerce data layer. The ability to identify a consumer actively researching or purchasing, for instance, running shoes on Amazon, and then precisely target them on Netflix with the same intent signals represents a profound enhancement to the capabilities of Amazon’s Demand-Side Platform (DSP).
The Measurement Revolution: Closing the Loop on CTV
While the targeting capabilities are undoubtedly compelling, it is the implications for measurement that fundamentally alter the advertising paradigm. Amazon DSP has historically possessed a structural advantage in attribution. When a brand utilizes Amazon’s commerce data to reach an individual demonstrating intent within a relevant category, and that individual subsequently makes a purchase on Amazon, the entire consumer journey is traceable within a single ecosystem—from initial signal to ad exposure to final purchase.
The advent of direct purchasing through the television screen, while still nascent and scaling, introduces new complexities. The consumer journey becomes longer and less direct. However, Amazon Marketing Cloud (AMC) is designed to bridge this gap by connecting CTV impressions to in-Amazon retail outcomes, such as product page views, add-to-cart events, and completed purchases. This sophisticated analytics suite provides advertisers with a critical link between their CTV investments and tangible e-commerce results.
For Netflix inventory, 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 is a forthcoming development on Amazon’s roadmap. Should this integration occur, the closed-loop measurement framework, which was previously confined to Amazon’s owned inventory, could extend to encompass Netflix, offering an unprecedented level of insight into the effectiveness of CTV campaigns.
Advertisers must remain cognizant of this measurement nuance when planning Netflix buys. While the targeting precision and the ability to reach relevant audiences on a premium streaming platform are strong selling points, the direct, closed-loop measurement to Amazon outcomes is not yet available. Nevertheless, the potential for this integration fuels considerable excitement within the advertising industry.
Data Influx: LinkedIn’s Professional Data Enters Amazon DSP
In a complementary yet distinct strategic move, Amazon DSP announced on May 7, 2026, its integration with LinkedIn’s professional data. This partnership allows advertisers to target the vast network of over one billion LinkedIn members using professional attributes such as job role, seniority level, and industry sector. These granular professional signals, previously lacking a viable pathway into programmatic CTV advertising, now offer a new dimension for reaching high-value business audiences. This capability is currently live in the United States, with no confirmed launch date for the UK.
This integration represents a significant expansion of Amazon’s audience capabilities, bringing a previously untapped demographic into its advertising ecosystem. While the Netflix integration extends Amazon’s existing data outward, the LinkedIn partnership inward-introduces entirely new audience segments.
Senior B2B professionals have historically presented a significant challenge for programmatic advertising at scale, particularly within premium environments. LinkedIn possesses the essential identity data, but credible, high-scale routes into high-quality CTV inventory have been limited. Amazon DSP now provides precisely this pathway. For B2B advertisers, this translates to professional identity targeting on the big screen, within high-attention viewing environments, eliminating the reliance on imprecise job-function proxies derived from third-party signals. The eventual rollout of this capability in the UK is poised to unlock a significant new channel for B2B marketing that has, until now, been largely inaccessible.
Navigating the Nuances: Limitations and Strategic Considerations
While the advancements are substantial, it is crucial for brands to understand the current limitations, particularly concerning measurement. For brands that do not conduct sales directly on Amazon, the closed-loop measurement case is inherently weaker. Without direct Amazon purchase data, attribution reverts to traditional third-party methods, ad tags, conversion APIs, and clean room integrations. While these tools are valuable, they do not offer the same seamless, end-to-end traceability as AMC within Amazon’s ecosystem. Therefore, advertisers should carefully assess their specific sales environment and product category before relying solely on AMC measurement as the primary rationale for a CTV buy.
This applies equally to Netflix inventory. The attribution narrative for Netflix advertising currently sits outside the AMC closed loop. The primary rationale for investing in this inventory, at present, rests on the exceptional targeting precision and the premium quality of the viewing environment, rather than direct closed-loop measurement back to Amazon outcomes. However, even without this direct link, the value proposition remains exceptionally compelling.
The forthcoming integration of LinkedIn data in the UK will further strengthen the argument for advertisers who do not rely on Amazon for sales. Professional identity targeting on premium streaming inventory has historically been unavailable at a meaningful scale, and CTV often defaults to a predominantly B2C channel. The integration of LinkedIn’s data through Amazon DSP, particularly for advertisers seeking to reach senior decision-makers at scale, promises to fundamentally alter this dynamic.
The Synergy of Innovation: A New Era for CTV
The dual announcements of May 2026 collectively amplify Amazon’s already formidable data advantage, reshaping its advertising stack in two critical directions simultaneously.
The Netflix integration extends Amazon’s most potent targeting data into the most premium CTV environments it has ever accessed. This enables broad awareness campaigns to be built upon genuine commerce intent, delivered within environments characterized by high viewer attention. Concurrently, the LinkedIn integration unlocks CTV targeting for audiences that were previously beyond reach at scale. This opens up premium streaming inventory to a new category of buyers with unprecedented precision.
The evolving media consumption landscape underscores the significance of these developments. In the UK, streaming accounted for 38% of total TV-set viewing in 2025, according to BARB, with live TV at 45%, but the gap is rapidly closing, particularly among younger demographics (16-34s). In the U.S., programmatic CTV is already a substantial $37 billion market, projected to grow by 14% year-on-year, according to eMarketer. The UK market, valued at £2.31 billion in 2026, is experiencing a similar surge of 15%, as reported by IAB UK. CTV is no longer a nascent channel; it has definitively arrived. Amazon’s recent innovations have equipped advertisers with the most advanced tools available to navigate this rapidly expanding and increasingly influential medium.
Forward-Looking Perspectives: What’s Next
Industry observers and agencies are actively assessing the practical implications of these advancements. Early indications from agencies that have begun running Amazon Audiences on Netflix inventory since the EMEA launch are encouraging, with initial scale results proving positive. The next critical phase involves rigorous stress-testing of the AMC measurement loop in real-world scenarios, focusing on the accurate connection of Netflix impressions to in-Amazon purchase outcomes and the validation of data promises. Findings from these evaluations are anticipated to provide further clarity on the platform’s efficacy.
The LinkedIn layer, upon confirmation of its UK launch date, is expected to be a priority for swift adoption. The window of opportunity before this capability becomes a standard offering in the market is likely to be short, making proactive planning essential for early movers.
The Defining Question for 2026: Infrastructure Beneath the Buy
The overarching question for advertisers in 2026 is no longer whether to invest in CTV. Most brands have already established a position on that strategic front. The more complex and critical question now revolves around the audience infrastructure underpinning CTV buys. Specifically, advertisers must determine whether their chosen infrastructure directly connects to measurable outcomes or merely approximates them. Amazon’s latest strategic moves undeniably position its platform at the forefront of providing outcome-driven solutions for the evolving CTV landscape.
