Magnite eyes 36% CTV growth and Google antitrust shift as revenue drivers

Magnite reported 36% year-over-year growth in second-quarter connected television contribution ex-TAC, which now represents 51% of its business mix. The company's CTV expansion is driven by programmatic adoption and partnerships with Netflix, Disney, Roku, and Warner. Senior Vice President Nick Kormeluk said potential remedies from Google's ad-tech antitrust trial could benefit Magnite's desktop and mobile web advertising business. He estimated Google holds roughly 60% market share in the relevant segment, whilst Magnite has 6% to 8% overall and approximately 15% of the non-Google supply-side platform market. Management raised its margin outlook above 37% and committed to allocating at least 50% of free cash flow towards share buybacks under a $200 million authorisation. The company has not included any potential antitrust remedy benefits in its forecasts.

Magnite targets CTV growth with Walmart, Samsung partnerships and AI ad tools.

Magnite targets CTV growth with Walmart, Samsung partnerships and AI ad tools. August 15, 2026 Key points. * Magnite is targeting connected-TV growth through partnerships with major platforms and media companies, including Disney, Roku, Fox and Netflix, while positioning itself as a key programmatic access point for CTV inventory. * New opportunities with Walmart and Samsung could expand future revenue: Walmart is using Magnite to distribute its user data across inventory sources, while Samsung selected Magnite to provide ad-serving technology for its TV home screen. Neither contributed revenue as of the second quarter. * Magnite is developing AI-driven advertising tools, including Magnite Orchestration, to automate buyer, seller and mediation workflows. Management raised its EBITDA-margin guidance to at least 37% and is also reducing infrastructure costs through a hybrid on-premises and cloud model. * MarketBeat previews the top five stocks to own by September 1st. Magnite NASDAQ: MGNI is positioning itself as a key infrastructure provider for programmatic connected-TV advertising as streaming platforms, television manufacturers and commerce-media businesses seek technology partners to manage inventory, data and demand, according to Head of Investor Relations Nick Kormeluk. Speaking at BofA Global Research's small- and mid-cap executive insights event, Kormeluk described Magnite as a supply-side platform that helps publishers sell digital advertising inventory by connecting it with demand from advertisers. The company operates across connected TV, mobile applications and web, digital out-of-home and other channels, though Kormeluk emphasized the company's CTV opportunity. CTV relationships and market concentration. Kormeluk said connected-TV inventory is more concentrated than traditional open-web advertising, with about 30 large global partners representing roughly 80% of global inventory. He said Magnite has relationships with all of those partners except YouTube and has become a primary access point for buyers seeking CTV inventory. He said the company's relationships with partners including Disney, Roku, Fox and Netflix have expanded over time. Rather than serving solely as another bidder for inventory, Magnite seeks to provide technology for ad serving, mediation, demand generation, yield management, identity and audience creation. "We have shown that we are that partner that can execute and bring people to the programmatic market," Kormeluk said. Kormeluk also said the company's CTV relationships have created a "halo effect" in its broader digital-video-plus, or DV+, business. He cited commerce-media partners including United Airlines, Pinterest, Best Buy, Redfin, RE/MAX, Expedia and PayPal, saying Magnite now has 21 partners relying on it exclusively as their programmatic partner. Walmart and Samsung opportunities. Among recent partnerships, Kormeluk discussed Walmart's expanding advertising ambitions following its Vizio acquisition plans and its announced purchase of demand-side platform Vibe. He said Walmart has tapped Magnite to help make its user data available not only on Vizio inventory but also across other inventory sources. Discover more Space stocks report Stock ratings screener Kormeluk said the opportunity with Walmart was not contributing to Magnite's results as of the second quarter and characterized it as a future growth opportunity. He also highlighted Magnite's win to provide ad-serving technology for Samsung's television home screen. Kormeluk said Samsung had historically sold that inventory through direct sales and insertion orders rather than through an ad server. Magnite won the business through a request-for-proposal process, he said. Samsung has the largest global installed base of smart TVs, according to Kormeluk, who added that home-screen advertising can account for as much as 30% of advertising revenue for other TV original equipment manufacturers. He said the Samsung home-screen opportunity similarly had not contributed revenue in the second quarter. Data, curation and AI workflows. Kormeluk said data activation is increasingly shifting toward the supply side because CTV publishers have greater control over user identifiers and data matches than publishers in the fragmented open-web market. Magnite does not charge publishers directly for using their first-party data, he said, but the data can help generate higher CPMs by improving advertisers' ability to target desired audiences. Magnite can also help partners monetize data beyond their owned-and-operated properties. Kormeluk cited LG's automatic content recognition data as an example, saying Magnite can help sell that data for use across non-LG inventory and share the resulting revenue with the partner. The company is also developing agentic advertising capabilities through products including Magnite Orchestration. Kormeluk said the technology is intended to reduce friction in advertising workflows that have traditionally relied on APIs and manual configuration. He said the platform can support buyer agents, seller agents and mediation agents while also providing infrastructure for privacy protections, payment workflows and inventory monetization. Magnite is targeting agency spending still conducted through insertion orders, which Kormeluk described as a process that can take weeks to develop, test and refine. He said Magnite's tools can complete comparable testing and creative refinements in minutes. Growth priorities and margin outlook. Kormeluk said Magnite's core operating priority is to grow advertising spend and revenue rather than pursue take-rate expansion. He said the company aims to add services and inventory opportunities for publishers while maintaining a cost structure that makes outsourcing to Magnite more attractive than building technology internally. He said the company has raised its EBITDA-margin guidance three times during the year, most recently to at least 37%. Kormeluk said Magnite's second-quarter top-line beat of $10 million translated into an $8 million EBITDA beat, which he said reflected the company's expected high incremental flow-through once revenue growth exceeds 10%. Magnite is also focused on reducing its cost per impression, he said. The company has moved portions of its CTV infrastructure to a hybrid model, using on-premises systems for predictable volume and cloud capacity for demand spikes. Kormeluk said the company has reduced cost per impression by strong double-digit percentages annually. On investor concerns, Kormeluk said the main question centers on the outlook for DV+. Open-web advertising faces pressure, while mobile app, streaming, audio, digital out-of-home and commerce media have healthier trends, he said. He characterized the near-term DV+ outlook as generally flat, while arguing that faster-growing parts of the business should become a larger portion of the mix over time. About Magnite (NASDAQ:MGNI).

Ad decisioning is migrating to the supply side.

Ad decisioning is migrating to the supply side. Senior reporter covering martech platforms, attribution, and CMO strategy. For a decade, the ad tech pitch from the supply side was simple: bring inventory, let the demand-side platform decide who buys it. That division of labor is breaking down. Across CTV and open web supply, sell-side platforms are pulling the actual buying decision, not just the auction, onto their own infrastructure, and Magnite's second-quarter earnings show why the shift is accelerating now rather than later. The auction was never the valuable part. Magnite reported second-quarter revenue of $192.8 million, up 11% year over year, with CTV contribution ex-TAC climbing 36% to $97.1 million, beating the company's own guidance range. CEO Michael Barrett used the earnings call to frame those numbers as evidence of a structural move rather than a cyclical one. "We are uniquely positioned between supply and demand, and with our agentic offerings we believe we will benefit from serving as vital infrastructure for the future of digital advertising," Barrett told investors. The mechanism behind that claim is SpringServe, Magnite's ad server for streaming and CTV, which the company has spent the past year turning from a passive delivery system into an active one. SpringServe now handles inventory packaging and audience routing itself, using AI models to decide which impression serves which campaign at which price, work that used to sit exclusively on the demand side inside a DSP's bidding logic. Orchestration, not just optimization. In June, Magnite layered a second piece on top: Magnite Orchestration, infrastructure built specifically so autonomous buying agents can communicate and coordinate with the supply side directly, rather than routing every decision through a human trader or a DSP's own agent layer. Barrett was careful to draw a line around what this is not: "We are introducing products that are DSP-like," he said, "but in no way, shape or form are trying to replace the DSP." The distinction matters less to advertisers than the practical effect: more of the decision about which impression is worth what now happens on infrastructure Magnite owns. That infrastructure is increasingly stitched to commerce data the DSP side can't easily replicate. Magnite has built integrations with Fanatics, CVS Media Exchange, Best Buy, PayPal Ads and Walmart Connect, pairing first-party retail signals directly with its own inventory before a bid ever reaches an exchange. Publishers, in other words, are no longer just selling impressions. They're selling impressions pre-packaged with the audience data needed to price them well, a job that used to belong entirely to the buy side. The rest of the supply side is making the same bet. Magnite is not moving alone. PubMatic's agentic push with Optable follows the identical logic: give publishers the tooling to act on their own first-party data instead of handing it upstream. And the pressure is coming from both directions at once, since DSPs are simultaneously rebuilding themselves around AI agents that promise to do a media planner's job in a chat window. Every layer of the stack is trying to own the decision at the same moment, and the supply side has one advantage the buy side does not: it sits closest to the first-party data an agent actually needs to be accurate. None of this means the DSP disappears. Magnite's own CTV contribution ex-TAC, while up sharply, is still a fraction of what flows through the demand side industry-wide, and Barrett's insistence that Magnite isn't "trying to replace the DSP" is as much a hedge against antagonizing his platform's biggest customers as it is a technical description. What's changing is where the profitable, differentiated work happens. Auction mechanics are increasingly commoditized; deciding which impression, at which price, for which audience, backed by proprietary data, is where the margin is moving. The trade-off buyers should weigh. There is a real cost to this consolidation, and it is worth naming rather than assuming away. When a supply-side platform owns both the inventory and the decisioning logic that prices it, the transparency buyers have spent years demanding from DSPs does not automatically carry over. A platform that packages its own audience data with its own inventory and prices both in one motion has less incentive to show its work than an independent auction did. Marketers who welcomed SSP-side AI for the efficiency gain should also expect to push harder for auditability, because the black box did not disappear, it just moved one layer closer to the publisher. Get the week's best tech coverage. Free. Read by thousands of HR, tech, and business leaders. What it means for the marketing leader. For a brand or agency buying CTV and programmatic inventory, this shift changes what to ask a supply-side partner. It's no longer enough to ask which publishers a platform represents. The better question is whose first-party data and decisioning logic sits behind the inventory before it ever reaches a bid request, because that logic increasingly determines price and performance before the DSP gets involved. Marketers who treat SSPs as a passive pipe are going to find pricing and targeting decisions being made upstream of their own media plan, by systems they never evaluated. It also raises a measurement question worth asking now rather than after a quarter of murky reporting: if a supply-side platform's own AI is choosing which impression serves a campaign, buyers need transparency into that logic, not just the price it produces. That scrutiny is exactly the kind CTV measurement has been building toward, as show-level CTV reporting becomes the baseline expectation rather than a differentiator. How to evaluate a supply-side partner now. Ask three things before the next upfront or programmatic RFP: what first-party data sources feed the platform's decisioning models, what visibility you get into why a given impression was priced or routed the way it was, and whether the platform's agentic tools are additive to your DSP's own AI stack or duplicative of it. Supply-side platforms that can't answer the first question clearly are still selling inventory the old way, whatever the marketing deck says. The ones that can are the ones worth building a direct relationship with, because the decision that used to happen exclusively in your DSP is, increasingly, already made by the time your bid request arrives.
