Microsoft Advertising is closing the Xandr DSP, layoffs pending🔒
Source: Digiday
May 14th, 2025

Summary: Microsoft Advertising will sunset its DSP, Microsoft Invest (formerly known as Xandr) by February 28, 2026, per a company blog post. Microsoft’s embrace of AI is behind the decision; the company says the demand-side platform (DSP) model doesn’t align with its future vision of "more private and personalized advertising experiences for a conversational and agentic world." Layoffs are part of the move.
Microsoft is consolidating its buy-side capabilities into the into the Microsoft Advertising Platform, a more simple, self-service buying tool (not too dissimilar from Google Ads and Meta Ads Manager). As part of its strategic shift to AI, Microsoft has integrated generative AI into its ad tools with Copilot.
Microsoft will continue to provide access to its ad inventory through third-party DSPs and will continue to prioritize its sell-side tech for publishers Microsoft Curate and Microsoft Monetize.
The Xandr DSP has a notable history, originating as AppNexus🔒before being acquired by AT&T in 2018 and rebranded as Xandr. Microsoft then acquired Xandr from AT&T in 2021.
Opinion: When Microsoft cites "a conversational and agentic world" as incompatible with "the industry's current DSP model," they're essentially declaring the death of complex programmatic UIs. The future of media buying won't involve humans meticulously adjusting bid parameters in DSP dashboards. It will be AI agents having conversations with other AI agents to execute campaigns.
The economics make this pivot inevitable. Transparent DSPs operate on razor-thin margins with high operational costs and fierce competition. Meanwhile, black-box solutions like Google's Performance Max and Meta's Advantage+ (and the soon-to-be-launched Microsoft PerformanceAdvantageMax+++Turbo) already deliver fantastic performance with minimal human intervention. Because their promise is performance and ease-of-use, they are able to justify obscuring cost and taking high margins. Microsoft is simply the first major player with the courage to admit that continuing to invest in traditional DSP infrastructure makes little business sense when the entire industry is racing toward AI-powered automation. (To be fair, it's convenient courage, as Xandr has been losing market share and clout in the DSP sector for a while.)

This decision becomes even clearer when you consider Microsoft's booming $20B ad business—much of it driven by LinkedIn's walled garden. Why pour resources into a struggling open web DSP when your fastest-growing ad revenue streams don't even rely on it? LinkedIn's success demonstrates that controlled environments with proprietary data and simplified buying interfaces are where the real money is.
What's telling is Microsoft's decision to retain their publisher-focused tools like Curate and Monetize, which will enable them to continue monetizing the open web using their data. This signals where the real value lies in tomorrow's ecosystem: controlling premium inventory access (supply) rather than facilitating its purchase (demand). In a post-cookie, agentic-AI world, where third-party data is less valuable and algos / UIs become increasingly commoditized, the moat comes from being the gatekeeper to quality inventory and first-party data, not necessarily the buying layer.
For the industry, this temporarily accelerates consolidation around the remaining major DSPs—The Trade Desk, Amazon, Google DV360, Yahoo, and other incumbents will absorb Invest’s displaced enterprise business. But the bigger story is how quickly we're returning to black-box buying models that DSPs were supposed to replace—just with "AI" as the new justification for opacity.
Buyers, beware!

Two Final Q1 Earnings Reports!
Walmart (👍): Revenue was up 2.5% to $165.6B, missing estimates. Global ad revenue grew 50%, and its US retail media arm, Walmart Connect, grew 31%. Ads are offsetting margin pressure from tariffs and inflation. The retailer affirmed its cautious full-year guidance. Shares closed slightly lower.
Dentsu (👍): Net organic revenue was up 0.2%, driven by strength in Japan. The Japanese agency holding company believes it will bottom-out in H2 before returning to growth this year, but warned of macro economic challenges (yup, tariffs). Dentsu affirmed its 2025 full-year guidance of 1% organic revenue growth. Shares rose by single digits.

The Legality Of RTB In Europe Has Been Settled, And Nobody’s A Winner - After years of legal battles, a Belgian appeals court has finally settled the GDPR case targeting the IAB Europe's Transparency & Consent Framework (TCF). The court affirmed that IAB Europe is a joint data controller, which means it must get consent alongside other vendors when collecting data for ad targeting. The court ruled that TC Strings (the annoying consent pop-ups) constitute personal data and upheld a previous $281,000 finle. The good news for publishers and ad tech companies using TCF is that they don't need to change their current practices because the ruling only applies to an older version of the framework which has since been updated. Here’s Tony Katsur, Head of the IAB Tech Lab, with helpful clarification.
No. The TCF is not illegal. Anyone peddling that narrative is either grossly misinformed or a liar. The ruling from the Belgian Market Court yesterday confirmed several things the industry anticipated and has remedied or is prepared to remedy:

DoubleVerify Sues Adalytics, Alleging Defamation🔒- At issue is an Adalytics report from March claiming that DoubleVerify's pre-bid filters sometimes fail to block even self-disclosed bot traffic. DoubleVerify says the implication that advertisers are being charged for invalid impressions is false and misleading. DoubleVerify contends that the report was published with "actual malice" to intentionally harm its reputation and promote Adalytics' own commercial services. Adalytics maintains its research is in the public interest and intends to vigorously defend its work. The lawsuit follows other critical reports from Adalytics and rebuttals from DoubleVerify, including DV previously publishing its own analysis to debunk Adalytics' methodologies and threatening legal action against Adalytics collaborator, CheckMyAds. Adalytics is also facing a separate defamation lawsuit from Colossus SSP, the subject of a separate Adalytics report. Let’s … not sue each other?

Chase’s Ad Business Drove $12B in Customer Spend Last Year🔒- The financial giant's advertising arm, Chase Media Solutions, drove $12B in customer spend by serving 18B targeted "Chase Offers" through its app and website. That's a 31% year-over-year increase in attributed purchases by its 71M digital banking users. Built from the 2022 Figg acquisition, Chase's platform operates on a pay-per-conversion model. To stand out in the crowded commerce media landscape, Chase Media Solutions emphasizes its ability to leverage spending insights from across multiple retailers—unlike single-retailer platforms—and target offers for both online and in-store sales. Plans are underway to further personalize these deals and expand their promotion into Chase's physical branches and ATMs. It is also exploring major sponsorships through its Madison Square Garden billboard in New York.
Netflix upfront focuses on new ad tools powered by audience data and AI🔒- Netflix detailed the US rollout of the Netflix Ads Suite, its in-house tech designed to give marketers global reach and precise targeting. Ad chief Amy Reinhard announced new clean room integrations with partners like LiveRamp, Experian, and Acxiom, and confirmed the platform will now leverage its extensive viewing history for ad selection and develop its own brand lift metrics. The initiative also introduces new formats, including shoppable mid-rolls and AI-powered dynamic product placement within hit shows. Netflix's ad tier, launched in late 2022, now has 94M global monthly active users. The streamer is betting that its vast data assets can make its ad business as compelling as its content.
Cable Megadeal: Charter to Buy Cox In $34.5 Billion Merger - This major acquisition will see Charter Communications take over Cox Communications, creating a new cable giant. Charter is the nation's second largest cable company, and Cox has 6 million subscribers. Charter CEO Chris Winfrey will lead the combined company, which will adopt the Cox name while continuing to use Spectrum as its consumer-facing brand; Cox CEO Alex Taylor will become board chairman. The deal aims to provide significant scale in broadband and video to compete more effectively with tech giants and streamers. The transaction is expected to close in 2026 pending regulatory approvals. Executives say they face a difficult regulatory environment, so all eyes will be on government approval.
