Stagwell has deepened its partnership with The Trade Desk in a deal specifically designed to boost its agentic AI capabilities, moving in the opposite direction of other major holding companies that are souring on the DSP. The deal positions Stagwell to embed TTD's programmatic infrastructure more deeply into AI-driven media buying workflows. (Digiday, April 28)
Impact · This signals a strategic divergence among holding companies on whether DSP relationships should be commoditized or elevated into competitive differentiators. Agencies outside the Big 6 may find opportunity in taking strong tech-partner positions rather than hedging. For brands evaluating agency partners, DSP alignment is becoming a proxy for AI readiness and media buying philosophy.
Action · Audit your agency's current DSP strategy and assess whether your Trade Desk, DV360, and Amazon DSP allocations reflect a deliberate competitive thesis — or just legacy inertia. If you're at a mid-size agency, evaluate whether a deeper single-DSP partnership could accelerate your AI capabilities faster than a neutral stance.
Pinterest launched audience extension on CTV via TV Scientific, letting advertisers buy Pinterest audiences on third-party properties. Meta and Pinterest showcased CTV API integrations at Miami's ad tech conference. Separately, Albertsons began injecting retail media first-party data into YouTube advertising, following a similar Kroger-DV360 pact in March. IAS launched Total TV, offering show-level, genre, and rating transparency across Disney, Paramount, and Amazon Prime Video. (Marketing Dive, Digiday, April 27-28)
Impact · CTV is rapidly becoming the channel where social intent data, retail purchase data, and streaming inventory converge. Agencies can now layer Pinterest shopping intent or Albertsons purchase behavior onto CTV buys — a fundamentally different planning model than traditional TV. IAS's measurement push addresses the transparency gap that has slowed CTV adoption for performance-focused brands.
Action · Build a CTV test plan this quarter that combines at least two data layers — e.g., Pinterest audience extension plus retail media signals — and measure incremental lift against your standard CTV buys. Use IAS Total TV benchmarks to establish show-level performance baselines.
Adthena launched ChatGPT AdBridge, a tool that repurposes existing Google Ads accounts into ready-to-run ChatGPT campaigns. The tool addresses a core problem: advertisers currently have no standardized way to set up, manage, or measure ads within ChatGPT's conversational interface. Coverage from both Search Engine Land and Digiday describes advertisers as 'flying blind' on ChatGPT ads. (Search Engine Land, Digiday, April 27)
Impact · This is the first major tooling play for ChatGPT advertising — the equivalent of early Google Ads Editor for a new channel. Agencies that move early will define best practices and accumulate performance data before competitors. However, the tool's Google Ads dependency means campaigns will initially mirror search intent patterns rather than conversational ones, creating an optimization gap agencies can exploit.
Action · Run a pilot conversion of one client's top-performing Google Ads campaign through Adthena's ChatGPT AdBridge. Document performance differences versus Google to begin building proprietary benchmarks before the market matures.
Netflix is thriving on third-party DSPs and the company faces a strategic decision on whether to build its own ad tech platform. The streaming giant's programmatic expansion is creating new scale opportunities for advertisers already buying through existing DSP infrastructure. (Digiday, April 28)
Impact · For agencies, Netflix's DSP approach matters because it determines workflow complexity and data access. If Netflix stays on third-party DSPs, agencies benefit from consolidated buying. If Netflix builds proprietary ad tech, agencies face another walled garden with unique measurement, creative specs, and buying requirements — the Disney+ and Peacock playbook.
Action · Track Netflix's ad tech hiring and partnership announcements over the next 90 days. If your agency manages significant CTV budgets, scenario-plan for both outcomes: continued DSP access vs. a proprietary Netflix buying platform requiring dedicated team expertise.
A new study found that more than three in four people (77%) use AI for shopping-related activities, but trust drops sharply when actual spending is involved — nearly 1 in 3 consumers won't let AI spend money on their behalf. (Search Engine Land, April 27)
Impact · This trust gap defines the near-term ceiling for AI commerce. Agencies building AI-powered shopping experiences or recommending agentic commerce solutions to clients must design for a handoff moment — AI assists discovery and consideration, but humans close the transaction. Brands that force full AI autonomy risk cart abandonment and trust erosion.
Action · Review any client AI commerce or conversational shopping initiatives and ensure the UX includes a clear human-confirmation step before purchase. Use the 77% adoption figure in client presentations to justify AI investment while the trust data to argue for hybrid human-AI checkout flows.
Pattern
WHAT TO WATCH (30-90 DAYS): 1) Netflix ad tech decision: Monitor for engineering hires, patent filings, or partnership announcements that signal whether Netflix will build proprietary ad tech or remain DSP-agnostic. A decision either way will reshape CTV buying workflows by Q4. 2) Holding company DSP realignment: Stagwell's Trade Desk bet is the leading indicator — watch for WPP, Publicis, or Omnicom to announce competing exclusive DSP or AI partnerships in the next 60 days. The era of DSP-neutral positioning may be ending. 3) ChatGPT advertising measurement standards: Adthena's tool creates the first scalable on-ramp, but without agreed-upon KPIs, the channel remains experimental. Watch for OpenAI to release official ad reporting APIs or measurement partnerships by mid-summer. 4) Retail media + CTV convergence: The Albertsons-YouTube and Kroger-DV360 deals suggest every major retailer will have a CTV data partnership by Q3. Track Target, Walmart, and Amazon for similar announcements. 5) AI shopping trust threshold: The 77% usage / 33% refusal gap will be the metric to track — if trust improves by even 10 points, agentic commerce budgets will accelerate dramatically.
