LinkedIn wants to follow its users home.
The professional networking giant, owned by Microsoft, has struck a partnership with The Trade Desk that will allow advertisers to target LinkedIn’s audience data across connected television inventory for the first time. The deal, reported by Business Insider, represents the most ambitious move yet by LinkedIn to extend its advertising business beyond the confines of its own platform and into the fastest-growing segment of digital advertising: streaming TV.
The implications are significant. For years, B2B marketers have been confined to targeting professionals where they work — on LinkedIn’s feed, in its messaging products, across its display network. Now, those same marketers can reach a CFO watching Hulu after dinner or a procurement director streaming a documentary on a Saturday afternoon. The professional context travels with the person.
Here’s what makes this different from the dozens of other data partnerships that populate the ad-tech industry: LinkedIn’s first-party data is arguably the most valuable professional identity graph on the planet. More than a billion members have self-declared their job titles, company affiliations, industries, seniority levels, and skills. That data isn’t inferred from browsing behavior or modeled from purchase patterns. People type it in themselves, then update it when they get promoted.
The Trade Desk, for its part, has been aggressively positioning itself as the demand-side platform of choice for the CTV era. The Ventura, California-based company has built integrations with virtually every major streaming publisher and has been vocal about its ambition to become the primary buying platform for advertisers shifting budgets from linear television. Adding LinkedIn’s audience segments to its targeting capabilities gives The Trade Desk something no other DSP can currently offer: precision B2B targeting on the big screen.
The partnership works through a data-clean-room arrangement, according to the Business Insider report. LinkedIn audience segments are made available within The Trade Desk’s platform, but individual user data isn’t shared directly. Advertisers select the professional attributes they want to target — say, IT decision-makers at companies with more than 5,000 employees — and The Trade Desk matches those segments against its CTV inventory. No personally identifiable information changes hands in the open.
That architecture matters. A lot.
Privacy regulations have been tightening globally, and the advertising industry has been scrambling to find targeting methods that deliver precision without running afoul of GDPR, state-level privacy laws in the U.S., or the broader cultural backlash against surveillance advertising. Clean rooms have emerged as the industry’s preferred solution, allowing two parties to match their data sets without either side seeing the other’s raw information. LinkedIn and The Trade Desk are betting that this structure will satisfy both regulators and the enterprise clients who tend to be especially cautious about how their data is used.
The timing of this deal isn’t accidental. CTV advertising spending in the United States is projected to surpass $30 billion in 2026, according to estimates from eMarketer. And B2B advertisers, historically slow to adopt television as a channel, have been increasingly curious about streaming as a way to reach professional audiences outside of work hours. The problem has always been targeting. Linear TV offered broad demographic reach but nothing approaching the professional specificity that B2B campaigns require. CTV changes that equation — but only if the data layer is sophisticated enough.
LinkedIn has been quietly building its off-platform advertising capabilities for several years. The company launched its LinkedIn Audience Network in 2017, allowing advertisers to extend campaigns to third-party apps and websites. But CTV is a different animal entirely. The creative formats are different. The measurement challenges are different. And the competitive dynamics are different — LinkedIn is entering a space where giants like Google, Amazon, and Meta have been investing heavily.
But LinkedIn has something those companies don’t. Google knows what people search for. Amazon knows what they buy. Meta knows who their friends are. LinkedIn knows where they work, what they do there, and how senior they are. For a category of advertising that is fundamentally about reaching the right person at the right company with the right message, that’s an extraordinarily powerful data set.
Penry Price, LinkedIn’s vice president of marketing solutions, told Business Insider that the partnership reflects advertiser demand. “Our customers have been asking for ways to reach professional audiences across more touchpoints,” Price said. The CTV integration with The Trade Desk is the most direct answer to that request LinkedIn has offered to date.
The Trade Desk CEO Jeff Green has been making the case for years that CTV will eventually absorb the majority of television advertising budgets. In the company’s most recent earnings call, Green pointed to the accelerating shift of ad dollars from linear to streaming and argued that programmatic buying — the automated, data-driven purchasing of ad inventory that is The Trade Desk’s core business — would be the primary mechanism through which that shift occurs. The LinkedIn partnership strengthens that argument by adding a data layer that no competitor can easily replicate.
There are skeptics. Some ad-tech analysts have questioned whether B2B advertisers will actually spend at the scale necessary to make CTV a meaningful channel for LinkedIn’s business. Television advertising, even in its streaming form, requires significant creative investment. A 30-second spot costs real money to produce, and B2B marketers have traditionally been more comfortable with white papers, webinars, and display ads than with video storytelling. The gap between having the targeting capability and actually deploying it at scale could be wider than LinkedIn anticipates.
Others have raised questions about measurement. CTV advertising has long struggled with attribution — proving that a specific ad impression led to a specific business outcome. For B2B marketers, where sales cycles can stretch months or years and involve multiple decision-makers, the attribution challenge is even more acute. LinkedIn will need to demonstrate not just that it can deliver ads to the right professionals on their TVs, but that those impressions actually influence purchasing decisions.
Still, the strategic logic is hard to argue with. LinkedIn generated more than $5 billion in advertising revenue in Microsoft’s fiscal year 2025, making it one of the largest B2B advertising platforms in the world. But growth on the core platform is subject to the same pressures facing every social media company: there are only so many ad units you can show in a feed before the user experience degrades. Extending LinkedIn’s data into CTV opens an entirely new pool of inventory without requiring LinkedIn to create any of it. The streaming publishers provide the content. The Trade Desk provides the buying infrastructure. LinkedIn provides the audience intelligence. Everyone gets a cut.
Microsoft’s broader advertising ambitions are relevant context here. The company has been aggressively expanding its ad business across multiple surfaces — Bing, Microsoft Start, Xbox, and the recently integrated Netflix ad tier, which Microsoft powers. LinkedIn’s CTV push through The Trade Desk adds another dimension to that strategy, though it operates somewhat independently given LinkedIn’s distinct brand and sales organization.
The competitive response will be worth watching. Oracle’s advertising division, which once offered B2B data targeting through its Data Cloud, shut down that business in 2024. Bombora and other B2B intent-data providers have partnerships with various DSPs, but none can match LinkedIn’s scale or the self-reported nature of its data. Demandbase and 6sense offer account-based advertising capabilities, but their CTV offerings are nascent compared to what LinkedIn and The Trade Desk are assembling.
And then there’s Amazon. The e-commerce giant has been building its own DSP with CTV capabilities, powered by its vast trove of purchase data. Amazon doesn’t have LinkedIn’s professional data, but it has something arguably just as powerful for certain categories: it knows what businesses buy through Amazon Business, its rapidly growing B2B procurement platform. If Amazon decides to make that data available for CTV targeting, LinkedIn could face a formidable competitor in precisely the space it’s trying to claim.
For now, though, LinkedIn and The Trade Desk have the field largely to themselves. The partnership is expected to be available to advertisers in the second half of 2026, with an initial rollout focused on the U.S. market. International expansion will follow, though the timeline depends on regulatory approvals and data-transfer agreements in various jurisdictions.
The deal also signals something broader about the direction of digital advertising. The era of walled gardens — where platforms kept their data locked inside their own buying systems — is giving way to a more interconnected model where data owners and media buyers collaborate through privacy-safe infrastructure. LinkedIn keeping its data within a clean room while making it accessible through The Trade Desk’s platform is a template that other data-rich companies are likely to follow.
So what does this mean for the CMO at a mid-market SaaS company trying to reach enterprise buyers? It means that for the first time, she can run a television campaign with the same kind of professional targeting she’s used to on LinkedIn. She can serve a 30-second brand spot to VPs of engineering at Fortune 500 companies while they’re watching streaming content on their living room TVs. She can measure whether those impressions correlate with increased engagement on her LinkedIn company page or her website. And she can do all of it through a single buying platform.
That’s a meaningful expansion of what’s possible in B2B marketing. Whether it translates into meaningful revenue for LinkedIn and The Trade Desk depends on execution — on how well the targeting performs in practice, on how accurately the clean-room matching works at scale, on how quickly B2B creative agencies adapt to producing television-quality content for their clients.
The pieces are in place. The question is whether the market is ready to use them.
