Microsoft Advertising this month extended LinkedIn profile targeting into connected TV campaigns, opening a third buy-side activation path for a supply architecture that already runs through Microsoft Monetize, Microsoft's sell-side platform. The update gives advertisers the option of buying LinkedIn-fused CTV inventory directly inside Microsoft Advertising, in addition to the two demand-side platforms - Amazon DSP and The Trade Desk - that LinkedIn formally enabled one week earlier.

The announcement was made by Product Liaison Navah Hopkins during the SEM Stories event on May 14, 2026. According to Hopkins, advertisers can now target connected TV audiences using LinkedIn profile attributes tied to a user's profession, including industry, job function, company category, and other professional identity signals.

Hopkins framed the feature as a way to build "really meaningful" audience lists that are less dependent on click-based intent signals, repeatedly emphasizing during the session the convergence of brand and performance marketing.

The architecture being extended is not new in its core mechanics. It is the same supply pipeline that LinkedIn detailed in its May 7, 2026 Pressroom announcement, with one critical addition: Microsoft Advertising itself now sits alongside Amazon DSP and The Trade Desk as a buy-side activation point. The piece that does not change is Microsoft Monetize, which functions as the structural pivot of the entire arrangement.

Microsoft Monetize is the pivot, not the DSPs

The targeting is not built on IP address matching or device-level household graph identifiers in the manner of some CTV vendors. According to LinkedIn's Help Center documentation on CTV Ads via DSP, the company has partnered with Microsoft's Monetize Supply-Side Platform to provide access to buying through external DSPs. Microsoft Monetize - originally built as AppNexus SSP before AT&T rebranded it as Xandr Monetize in 2019, then absorbed into Microsoft following the 2022 acquisition - sits at the center of the supply flow.

LinkedIn's documentation describes the data flow in three precise steps. First, the platform builds a curated audience segment using approved professional facets based on members' setting preferences. Second, it creates a private marketplace deal, or PMP, in Microsoft Curate - the curation layer that sits on top of Microsoft Monetize - which includes LinkedIn audiences and CTV inventory from premium publishers. Third, that PMP deal is delivered into the buyer's DSP account, where it can be activated.

In effect, every CTV campaign that combines LinkedIn audiences with streaming inventory under this program flows through Microsoft Monetize on the supply side. The DSP is interchangeable. The SSP is not. Amazon DSP can be swapped for The Trade Desk, and now for Microsoft Advertising itself, but Microsoft Monetize remains constant in every configuration. The LinkedIn audience graph, packaged into Deal IDs inside Microsoft Curate, never leaves Microsoft-controlled SSP infrastructure before it reaches a DSP.

That structural detail matters because Microsoft owns LinkedIn and operates Microsoft Monetize. No other SSP in the broader programmatic CTV ecosystem can package Microsoft Monetize's CTV inventory with LinkedIn's professional graph at the deal level, because no other SSP has access to that data. PPC Land documented this dynamic on May 7, 2026, describing the arrangement as a structural advantage that exists solely because of the corporate relationship between Microsoft Monetize and LinkedIn - both Microsoft assets, deployed together to preserve the SSP's relevance inside an ecosystem where the DSPs are mostly owned by competitors.

How the targeting actually works

The audiences flowing through the LinkedIn PMP deals are tied to member preferences and professional attributes that members themselves declare on the platform - job title, industry, seniority, function, company - not behavioral inferences or third-party cookies, and not household-level matching via IP address.

LinkedIn writes in its documentation that DSP activation uses a Deal ID and approved audience criteria, with security controls designed to protect data in transit and at rest, and access restricted to authorized systems and personnel. The PMP mechanism is what allows LinkedIn to honor member preferences while exposing the audience signals to outside buyers: the buyer never sees individual member data, only the audience segment encoded inside the Deal ID.

Activation requires a Deal ID, and LinkedIn notes that generating the Deal ID can take up to five business days. The buyer must provide their DSP Seat Name and Seat ID to the LinkedIn representative before the Deal ID is generated.

The targeting attributes named publicly across the LinkedIn and Microsoft announcements include job title, industry, seniority, function, company category, and broader professional identity signals. LinkedIn's May 7 Pressroom post specified job title, industry, and seniority as the three attributes flowing into the Amazon DSP integration. Today's Microsoft Advertising update adds job function and company category to the publicly named list, alongside what Hopkins described as professional identity signals.

Three DSP activation paths

The architecture now supports three distinct buy-side activation routes.

The first route is Amazon DSP, formalized on May 7, 2026 through the joint LinkedIn and Amazon announcement. David Roter, Senior Director and Head of Global Agencies and Video Solutions at LinkedIn, framed the partnership as expanding "how advertisers can buy LinkedIn CTV Ads, while still reaching the buyers that matter most to deliver measurable business outcomes at scale." Chris Conetta, Director of Omnichannel Supply at Amazon Ads, described the integration as combining "LinkedIn's audiences with the scale and impact of streaming TV inventory" for full-funnel CTV strategies inside Amazon DSP.

The second route is The Trade Desk, named alongside Amazon DSP in LinkedIn's Help Center documentation as one of the two external DSPs supporting CTV Ads via DSP. Customers with an existing Trade Desk account can also access additional iSpot measurement integration specifically tied to that pathway.

The third route, formalized through Hopkins' announcement today, is Microsoft Advertising itself. By layering LinkedIn profile targeting onto Microsoft Advertising's CTV inventory, Microsoft brings the same supply pipeline that flows through Microsoft Monetize into its own demand-side product. This is the route that closes the loop after Microsoft shut down its Xandr-derived DSP earlier in 2026.

Microsoft announced on May 14, 2025 that it would discontinue Microsoft Invest, the demand-side platform inherited through the Xandr acquisition, effective February 28, 2026. The programmatic buyers who used Microsoft Invest were directed toward Amazon DSP, which was named the preferred transition partner. What Microsoft retained internally was the Microsoft Advertising platform - its native ad product, distinct from the shuttered Invest DSP - plus Microsoft Monetize on the supply side. Today's update reconnects the LinkedIn data layer to that native Microsoft Advertising surface, without reviving Microsoft Invest.

Amazon DSP integrated Microsoft Monetize into its Certified Supply Exchange program on October 7, 2025. That move gave Microsoft Monetize preferred-partner status inside Amazon's ecosystem, five months after Microsoft confirmed the shutdown of its DSP. The LinkedIn data integration announced on May 7 sat on top of that supply-side foundation. The Microsoft Advertising activation announced today extends the same foundation back into Microsoft's own product.

Eligibility, spend minimums, and creative requirements

The CTV Ads via DSP program is in testing for the external-DSP routes, and LinkedIn's published documentation outlines tight constraints around who can use it. The feature is currently available to limited LinkedIn managed accounts with a dedicated representative, and eligibility must be confirmed through that representative.

Geographic targeting through the DSP pathways is restricted to the United States. Language support is limited to English. The minimum spend is set at 50,000 US dollars over a 30-day period, and the minimum audience size required to activate a deal is one million members.

For advertisers committing to the larger CTV Select program - which routes inventory exclusively through NBCUniversal or Paramount - the budget threshold rises to 100,000 US dollars per ad set, with a recommended run time of two to three months and a fixed-rate CPM rather than the bidded rate used in general CTV Ads. NBCUniversal inventory under CTV Select includes channels such as NBC, Peacock, Bravo, and CNBC. Paramount inventory includes Paramount+, Pluto TV, CBS, MTV, Showtime, and Comedy Central. Live sports events are not eligible for CTV Select, though video-on-demand sports inventory is.

LinkedIn's Campaign Manager direct CTV route, which predates the DSP integration, additionally covers Canada alongside the United States and requires the Connected TV Only ad set toggle to be enabled, with maximum delivery as the bidding strategy.

On the creative side, LinkedIn's published specifications require video assets to be delivered in MP4 format at a 16:9 aspect ratio, with dimensions of 1920 by 1080 pixels recommended and 1280 by 720 pixels accepted. Bit rates between 15 and 40 Mbps are recommended, with 1.2 Mbps the minimum threshold. Audio must be delivered at 2-channel, -23 integrated LUFS, using PCM or AAC codec at a minimum of 192 Kbps and a 48 kHz sample rate. Video duration ranges from 6 seconds to 60 seconds, with 6, 15, 30, 45, or 60 second cuts recommended. Frame rates must be constant at 23.98, 24, 25, 29.97, or 30 fps. The maximum file size is 500 MB, and the codec is H.264.

LinkedIn notes in its documentation that some inventory might not accept 45 or 60 second ad formats, a constraint that reflects the variable specifications of individual streaming publishers in its network.

Measurement and reporting layers

The measurement architecture is layered across multiple providers. According to LinkedIn's documentation, advertisers running CTV Ads through a DSP get delivery metrics - impressions, reach, frequency, CPM, CPV, and spend - centralized inside the DSP. A separate iSpot integration, available only when buying through The Trade Desk, provides audience reach verification with real-time reach, impression, and frequency comparison against linear TV and other CTV buys. Kantar handles Brand Lift measurement for upper-funnel impact assessment, while LinkedIn itself provides custom reporting for additional signals.

The documentation flags a specific operational requirement: when iSpot is used for measurement, the LinkedIn deal must be kept as a separate line item inside the DSP campaign structure. Ad serving is supported through CM360 and Innovid VAST tags routed through the DSPs.

For CTV Ads via DSP campaigns, LinkedIn representatives provide advertisers with a wrap report that includes the professional demographic reporting that would normally surface in Campaign Manager. That step is necessary because the DSP routes do not flow back into LinkedIn's native dashboard the way Campaign Manager-originated campaigns do.

What this means for Microsoft Monetize

The deeper context for the announcement involves what Microsoft Monetize must accomplish commercially. After the Xandr DSP shutdown on February 28, 2026, the SSP no longer has a captive demand source. It now competes inside Amazon DSP against every other supply-side platform integrated into the Amazon ecosystem, including supply paths Amazon controls directly. Inside The Trade Desk, it competes against every SSP wired into the OpenPath system and the broader Trade Desk inventory pool. Inside Microsoft Advertising's own platform, the competitive pressure is lower, but the inventory still flows through the same Monetize pipes.

The LinkedIn data layer is what differentiates Microsoft Monetize from the rest. Microsoft owns LinkedIn, and no other SSP in any DSP ecosystem can pair Microsoft Monetize's CTV inventory with LinkedIn's professional graph at the deal level. That is a structural advantage rooted in corporate ownership, not in technology that could be replicated by an independent SSP.

LinkedIn's first-party attributes are declared by members themselves rather than inferred from behavioral signals. That distinguishes them from licensed firmographic data and from contextual segments built on content consumption patterns. The trade-off is that the integration is constrained to the audiences LinkedIn can package under its member settings.

The Hopkins announcement at SEM Stories adds a second commercial layer. By bringing the same supply architecture into Microsoft Advertising's own product, Microsoft now has a route for selling LinkedIn-targeted CTV inventory that does not depend on Amazon or The Trade Desk to execute the buy. For advertisers who prefer to stay inside Microsoft's ecosystem - or who already run Microsoft Advertising search and audience campaigns - the new path consolidates targeting under one interface.

Why this matters for the marketing community

Connected TV has historically been treated as a brand-heavy channel with weaker attribution than search or shopping campaigns. The professional-graph layer changes the targeting equation for B2B advertisers in particular, because it makes streaming inventory addressable along dimensions that programmatic CTV has not previously supported at scale.

The broader market context underlines the stakes. LinkedIn ads delivered a 113% return on ad spend for B2B marketersin 2024, according to Dreamdata's LinkedIn Ads Benchmarks Report 2025, which analyzed 23 million sessions and more than 220,000 customer journeys. The same data set showed LinkedIn capturing 39% of total B2B advertising budgets by the second half of 2024, up from 31% in the first half.

CTV spending sits inside a separate growth curve. Industry projections cited by PPC Land in coverage of Microsoft's Premium Streaming launch on August 4, 2025, place connected TV advertising spending at 33.35 billion US dollars in 2025, with CTV's share of media budgets projected to double from 14% in 2023 to 28% in 2025. Research published alongside that coverage indicated that 72% of marketers planned to increase programmatic advertising investment in 2025.

The combination - heavy budget growth on CTV and on LinkedIn separately - creates the commercial logic for fusing the two. Whether the fusion materially shifts where CTV budgets land is an open question. Innovid expanded its own LinkedIn CTV integration on July 21, 2025, enabling advertisers to execute LinkedIn CTV campaigns alongside social, digital, and traditional CTV channels through a single platform interface. That partnership focused on workflow consolidation at the campaign management layer. The current arrangement operates one layer below, inside the supply infrastructure of Microsoft Monetize, with the DSPs serving as buy-side endpoints rather than as the source of differentiation.

The brand safety question sits inside a broader market context. The CTV Ads documentation references first- and third-party automated and manual checks on bid requests, block lists, allow lists, IAB category exclusions, and custom DoubleVerify profiles available by request. Those controls operate inside the LinkedIn Audience Network architecture and extend to CTV.

Open questions

Several elements of the architecture remain unspecified. Microsoft Advertising has not disclosed the full list of LinkedIn targeting attributes exposed through the Microsoft Advertising route, and whether they match the externally available set or extend further. The integration through external DSPs is US-only, and neither LinkedIn nor Microsoft has published a roadmap for expansion into Canada, the UK, or other markets where LinkedIn already runs CTV campaigns directly through Campaign Manager. Pricing detail beyond the 50,000 US dollar minimum for the DSP routes is not addressed.

Account-based marketing - the targeting of specific named companies - is a likely next test case for the architecture, given that LinkedIn's graph supports company-level segmentation natively but the announcements do not confirm whether that segmentation is available through every DSP pathway. The measurement question is partially answered through iSpot, Kantar, and the DSP-native reporting layers, but cross-platform attribution remains a function of what advertisers can build themselves.

For Microsoft, the strategic question runs deeper. Microsoft Monetize must demonstrate that the LinkedIn data layer generates enough B2B demand across all three DSP endpoints to justify its commercial position. If demand materializes inside Microsoft Advertising and not inside the external DSPs - or vice versa - the architecture will tilt accordingly. The three-route design hedges against a single point of failure on the buy side, but it also requires Microsoft Monetize to satisfy three sets of buyer expectations simultaneously.

Timeline

Summary

Who: Microsoft Advertising, with Product Liaison Navah Hopkins announcing the update at the SEM Stories event. The supply-side architecture sits on Microsoft Monetize, Microsoft's SSP (the former Xandr/AppNexus platform). LinkedIn provides the audience data layer, also owned by Microsoft. Three demand-side platforms now activate the resulting deals: Amazon DSP, The Trade Desk, and Microsoft Advertising itself.

What: An expansion of LinkedIn profile targeting into connected TV campaigns, with the Microsoft Advertising platform added as a third buy-side activation path alongside Amazon DSP and The Trade Desk. Targeting attributes include industry, job function, job title, company category, seniority, and broader professional identity signals. The targeting is delivered through PMP deals generated inside Microsoft Curate on top of Microsoft Monetize, with audience data flowing from LinkedIn's first-party member graph rather than from IP-based household matching or third-party cookies. Activation requires a Deal ID, which can take up to five business days to generate. Minimum spend is 50,000 US dollars over a 30-day period through the external DSP routes, and the minimum audience size is one million members.

When: The Hopkins announcement was made today at the SEM Stories event. The supporting LinkedIn programmatic CTV announcement was published on May 7, 2026. The Help Center documentation describing CTV Ads via DSP, CTV Select, and CTV Ads specifications was last updated 7 days ago.

Where: Geographic eligibility through the DSP pathways is restricted to United States audiences. Language support is limited to English. LinkedIn's Campaign Manager direct CTV route additionally covers Canada, but the external DSP pathways are US-only. Microsoft Monetize operates on the supply side across more than 100 countries, though the LinkedIn-fused product runs only in the US for now.

Why: Microsoft Monetize lost its captive DSP when Microsoft Invest was shut down on February 28, 2026. To stay commercially relevant inside Amazon DSP and The Trade Desk - the two external DSPs now serving the buyers who used to run on Microsoft Invest - Microsoft Monetize must offer something competing SSPs cannot replicate. LinkedIn's professional graph is that asset, accessible only through Microsoft-owned infrastructure. Bringing the same architecture back into Microsoft Advertising closes the loop on the buy side, giving Microsoft a native demand product for the supply it controls without rebuilding the Invest DSP. For advertisers, the targeting fills a gap in programmatic CTV, where job-level professional segmentation has historically been unavailable at scale.
