Amazon is recalibrating its relationship with the agencies and adtech firms that helped build its retail-media dominance. While Amazon insists agencies remain central, many intermediaries say rising data costs and tool duplication echo earlier platform playbooks from Google and Meta—centralize strengths, limit external dependencies, and scale in-house automation. The result is a more controlled, AI-driven ecosystem that may reduce tooling diversity while boosting Amazon’s own ad stack. For marketers, the challenge will be balancing Amazon’s convenience and scale with the flexibility, transparency, and customization offered by independent partners.

The Trade Desk posted another strong quarter, with revenue up 18% to $739 million and EBITDA margins above 40%, but CEO Jeff Green’s focus remains philosophical. On the Q3 call, Green said the company’s “AI-first” Kokai platform and new tools—Open Ads, Deal Desk, Audience Unlimited, and Trading Modes—position TTD as the infrastructure layer of an open, transparent internet. CTV now accounts for half of total revenue, with Disney and Hearst partnerships lifting publisher yields by 23%. Yet Green acknowledged the open web’s challenges, calling the vision “more aspirational than factual” as walled gardens tighten control.

AppLovin beat expectations again, delivering a blowout quarter that affirmed its place among the most profitable players in adtech. Even as the company faces ongoing scrutiny over data practices and an SEC probe, its financial momentum appears unaffected. AppLovin is proving that controversy doesn’t always kill momentum. Its ability to execute quarter after quarter suggests marketers may be more pragmatic than moralistic, following results over rhetoric.

Pinterest reported Q3 2025 revenue of $1.1 billion, up 17% YoY and slightly ahead of forecasts, as global user growth and AI-driven ad features continue to lift engagement. Monthly active users climbed 12% to 600 million, with international markets up 16% and driving most of the gains. Yet softer Q4 guidance spooked investors, sending shares down 20%. CFO Julia Donnelly cited “moderating ad spend” among US retailers facing tariff pressures. Globally, Pinterest’s AI tools—visual search, generative creative, and shoppable feeds—are strengthening its position as the web’s most frictionless bridge between inspiration and purchase. Consistency remains Pinterest’s quiet advantage.

StackAdapt is overhauling programmatic out-of-home advertising with tools that let buyers see exactly where their ads will appear. The new platform experience includes real-world map views, screen previews, and venue-level pricing, solving one of OOH’s biggest pain points: visibility. VP of Inventory Development Gregory Joseph said the update responds directly to advertiser demand for proof of placement and transparency. As agencies push for unified reporting across CTV, mobile, and OOH, StackAdapt’s approach gives digital buyers the data and validation they expect. For advertisers, it marks a turning point—OOH can finally be planned, measured, and optimized alongside digital media.

Reddit COO Jen Wong told EMARKETER that the platform has evolved from explaining itself to advertisers to proving it can deliver results. “We’ve shown Reddit can drive real business outcomes,” she said, noting that nine of fifteen verticals grew ad spend by at least 50% YoY. Wong emphasized discovery as Reddit’s next frontier—especially in underexposed sectors like parenting and sports—and said product improvements will make communities easier to find. With ad revenues projected to climb 46.6% in two years, Reddit’s opportunity is one of scale and visibility, driven by authenticity and high-intent engagement.

Reddit’s Q3 earnings confirmed what advertisers have suspected: the platform’s community-driven ad model can scale profitably. Revenue jumped 68% to $585 million, crushing Wall Street estimates, while EPS of $0.80 easily beat forecasts. Global daily actives climbed 19% to 116 million, though US user growth slowed to 7%, down from 12% last quarter. Data licensing revenue rose 7% as Reddit continues to defend its content from unauthorized AI scraping—a fight central to its long-term strategy. For advertisers, Reddit’s results underscore its strength as a high-intent, performance-focused channel—even as slower domestic user growth raises questions about future expansion.

WPP cut its full-year outlook after Q3 organic revenue fell 5.9% to £2.46 billion, its steepest quarterly decline since 2020. New CEO Cindy Rose said the company “hasn’t gone fast enough” to meet client needs and outlined a turnaround focused on AI, operational efficiency, and simplifying its agency network. WPP’s slump reflects broader challenges facing holding groups in the AI era: proving value through speed, integration, and measurable results as brands increasingly turn to self-serve, platform-driven ad solutions.

At the Marketecture conference, MiQ’s global VP of strategy and partnerships, Moe Chughtai, said advertisers are finally connecting platforms like Meta, YouTube, and TV through clean room technologies that enable unified measurement. Traditional marketing mix models are being replaced by one- to three-month measurement cycles that allow for real-time optimization and smarter KPI alignment. The result: advertisers can move beyond isolated reporting and toward integrated, cross-platform performance strategies that strengthen confidence in ROI.

Elon Musk plans to sell paid placements within Grok’s AI-generated answers, marking his first major advertiser pitch since Linda Yaccarino’s departure. Grok, X’s in-house AI assistant built by xAI, will integrate ads directly into responses, offering brands high-intent, context-driven targeting. The move comes as X’s global ad revenues, projected at $2.26 billion in 2025, remain roughly half of pre-Musk levels. Musk says Grok will eventually automate the full ad-buying process, from creative grading to personalization, aiming to improve efficiency and performance. With user growth declining in every major region, the strategy hinges on whether brands trust Musk’s AI-led vision enough to re-engage.

The Trade Desk (TTD) posted Q2 revenues of $694 million, up 19% YoY and above expectations, driven by strength in connected TV and premium open-web inventory. However, cautious Q3 guidance cited slower advanced adtech adoption among large brands, macroeconomic budget pressures, and tariff-related spending risks. Shares fell nearly 40% in a day. For advertisers, the story underscores the open web’s importance as an alternative to walled gardens, with US programmatic open-web spend forecast to reach $48.8 billion by 2027. TTD’s future growth hinges on CTV, cross-channel targeting, and clean-room data collaboration to deliver premium inventory at scale.
