Samantha Jacobson, Chief Strategy Officer of The Trade Desk, is departing to join OpenAI
The Signal
Samantha Jacobson, Chief Strategy Officer of The Trade Desk, is departing to join OpenAI. The announcement came hours before The Trade Desk disclosed its Q1 2026 earnings, compressing two major news events into a single market cycle. Jacobson will retain a seat on The Trade Desk's board while the company conducts a search for her successor. The Q1 results themselves were a beat: $689 million in revenue against analyst projections, with The Trade Desk forecasting Q2 revenue of at least $750 million. However, the 12% year-over-year growth rate marks the company's slowest expansion since the Covid-era ad downturn of 2020. Simultaneously, supply-side platform PubMatic reported Q1 revenue of $62.6 million. The Trade Desk cited momentum across CTV, retail media, and data-driven buying, pointing to integrations with Dollar General, LinkedIn, Netflix, PacVue, and Skaai, along with newly launched agentic planning tools inside its Koa platform. CEO Jeff Green separately outlined a forward vision for the DSP that calls for fundamental changes in how marketers operate, with talks between The Trade Desk and Publicis still ongoing.
Why It Matters
The Jacobson departure is actually the most honest signal The Trade Desk has sent the market in years — and most analysts are reading it backwards. Her move to OpenAI isn't a loss for The Trade Desk; it's evidence that the company has already internalized the AI-native transition and no longer needs a traditional strategy executive to argue internally for what's obvious. The real story is that Jeff Green is rebuilding the C-suite around execution, not vision, because the vision is settled. What surface coverage misses is the timing's strategic logic. Announcing Jacobson's exit hours before an earnings beat isn't a crisis management failure — it's a calculated reset. Green gets to reframe any leadership vacuum narrative inside a revenue beat, and Jacobson's board retention means institutional continuity is preserved. This is a clean handoff designed to look messier than it is. The slower 12% growth rate is the number that deserves more scrutiny than the leadership change. The Trade Desk is bumping against the ceiling of what traditional DSP infrastructure can capture, and the Publicis talks, the Koa agentic tools, and the integration stack with Dollar General and Netflix are all moves toward a fundamentally different business model — one closer to a planning and intelligence layer than a buying desk. Green's "new breed of CMO" framing isn't aspirational; it's a direct warning to agency partners that The Trade Desk intends to commoditize their planning function. For senior marketers, the decision point is arriving faster than most procurement cycles can accommodate: do you deepen integration with The Trade Desk's agentic stack now, or find yourself renegotiating from a weaker position by Q1 2027?
The Exploit
Opportunity
Marketing leaders inside large advertisers—specifically those with $50M+ in programmatic spend—can lock in preferential integration terms with The Trade Desk's Koa agentic stack before the Publicis deal closes and Green resets pricing leverage. The 6-month window before Q1 2027 planning cycles is the last moment to negotiate as a partner rather than a dependent.
Risk
Agency-led programmatic teams are most exposed. If Publicis secures an exclusive or preferred structural arrangement with The Trade Desk, brands running media through holding company desks will inherit that deal's terms, not negotiate their own. The failure mode is arriving at Q1 2027 budget conversations with no direct integration, no data relationship, and no leverage—paying a planning tax on every dollar.
The Move
The Chief Media Officer or Head of Programmatic should initiate a direct commercial conversation with The Trade Desk before the Publicis deal concludes—targeting a formal partnership review before September 2026. Success looks like a signed data-sharing or co-planning agreement that survives any agency restructuring. This move belongs to the brand side, not the agency.

Winners & Losers
Winners↑
OpenAI's Emerging Ad Intelligence Division
Jacobson's arrival signals OpenAI is moving deliberately toward advertising infrastructure, not just tooling — importing institutional knowledge of programmatic buying, identity, and data strategy at the exact moment The Trade Desk is validating that AI-native planning is commercially viable. The competitive implication is that OpenAI could emerge as a planning-layer rival to The Trade Desk itself by 2027, rather than merely a vendor to it. Marketers should track OpenAI's product announcements in Q3 2026 closely, as Jacobson's fingerprints on any ad-adjacent roadmap will signal how quickly that threat materialises.
Retail Media Networks with DSP Integration Deals
The Trade Desk's direct integrations with Dollar General and Netflix — cited explicitly as Q1 momentum drivers — confirm that retail media networks positioned inside The Trade Desk's Koa ecosystem are gaining preferential access to agentic buying workflows, creating a structural moat against rivals operating outside that stack. Networks not yet integrated face growing marginalisation as automated planning tools optimise toward known, credentialed data partners by default. Retail media operators should accelerate partnership conversations with The Trade Desk before Q4 2026 planning cycles lock in platform preferences.
In-House Media Buying and Planning Teams
Jeff Green's explicit framing of a 'new breed of CMO' — combined with agentic planning tools inside Koa — is a direct enablement play for in-house teams willing to bypass agency intermediaries and operate The Trade Desk's stack directly. Brands that invest now in upskilling internal programmatic talent to operate agentic tools will be positioned to renegotiate agency retainers from a position of strength by Q1 2027. The window to build this capability before agencies adapt their own AI-augmented offering is narrow but real.
CTV Supply Partners Aligned with The Trade Desk Stack
With CTV cited as a primary growth vector and Netflix integration confirmed, supply partners whose inventory is addressable through The Trade Desk's agentic planning layer stand to capture disproportionate automated spend as Koa scales its planning recommendations. The mechanism is straightforward: agentic tools optimise toward accessible, credentialed inventory first, concentrating budget with integrated partners. CTV operators not yet in The Trade Desk's certified supply ecosystem should treat Q2 and Q3 2026 as the critical window to formalise integrations before buying automation further entrenches existing allocations.
Losers↓
Independent Media Planning and Buying Agencies
Green's 'new breed of CMO' language is not aspirational positioning — it is a direct competitive declaration that The Trade Desk intends to commoditise the strategic planning function that agencies currently charge margin on, by embedding that capability inside Koa's agentic layer. The Publicis talks underway confirm that even holding-company agencies are in a renegotiation posture, not a position of leverage. Independent agencies facing this pressure without holding-company scale should urgently differentiate on creative strategy and measurement consultancy — the functions least susceptible to automation — rather than competing on media execution where The Trade Desk is structurally advantaged.
Competing Demand-Side Platforms and Traditional DSP Infrastructure Vendors
The Trade Desk's 12% growth rate looks modest in isolation, but its integration depth across CTV, retail media, and identity — combined with agentic planning tools that create switching costs at the workflow level — means it is consolidating category leadership precisely as the underlying DSP model commoditises. Rivals offering straightforward programmatic buying without a credible AI planning layer will find buyer concentration accelerating toward The Trade Desk as procurement teams simplify vendor rosters through 2026 and into 2027. Competing platforms must either acquire differentiated data or planning assets quickly, or accept a narrowing role as execution pipes beneath The Trade Desk's intelligence layer.
Mid-Market Brands Dependent on Agency-Managed Programmatic Buying
Mid-market brands that have outsourced programmatic strategy entirely to agency partners are the least equipped to respond to The Trade Desk's deliberate shift toward direct CMO relationships and agentic self-service, as they lack the internal talent to operate Koa's evolving toolset and the scale to justify custom integration deals. The risk is being caught between agencies losing planning leverage and a platform increasingly optimised for sophisticated direct buyers — a position that erodes both media efficiency and strategic optionality. These brands should use Q2 and Q3 2026 to audit their agency contracts for data portability and begin building minimum viable in-house programmatic competency before the leverage dynamic fully shifts.
Strategic Outlook
The timing here echoes a pattern that's been building since 2023, when DSPs first started losing their most forward-looking talent to foundation model companies — not because the DSPs were failing, but because the foundational AI work had migrated upstream. What's different now is that The Trade Desk isn't just watching that talent drain; it's structuring around it. Jacobson's board retention is the tell. Compare this to how Google handled similar transitions during its post-DMA restructuring, where departing strategists simply left. The Trade Desk is threading continuity deliberately. The 12% growth ceiling is also not an isolated data point. Across the open web buying stack, every major DSP has been colliding with the same structural constraint: traditional audience-based buying is mature, and incremental gains require either moving up the stack into planning or down into identity infrastructure. The Trade Desk has been signaling the planning layer move since the Unified ID 2.0 coalition years, but the Koa agentic tools and the Publicis negotiation represent the first concrete monetization attempt on that thesis. For context, the last time The Trade Desk triggered this kind of C-suite and business model realignment simultaneously was during its 2020 post-Covid recovery sprint — which preceded three years of accelerated growth. The question now is whether the agency ecosystem responds faster than it did then, or whether The Trade Desk simply routes around it.
