Amazon vs. The Trade Desk: Supply Path Debate
The article examines a supply-path debate between Amazon and The Trade Desk over duplicated programmatic bid requests and how to reduce waste. Amazon (represented by Dr. Neil Richter) promotes an open scoring model — Dynamic Traffic Engine (DTE), an open-source SDK on GitHub — that evaluates marginal utility per path and can be deployed by SSPs so math, not relationships, select the best route. The Trade Desk (Mike O'Sullivan) advances verification-first tools — OpenPath and the next-generation Open Ads wrapper — to establish a control signal from publisher primary ad servers and prefer direct, high-trust paths. Forrester’s recent Omnichannel Advertising Platforms Wave named Amazon Ads a Leader and placed Trade Desk outside the top three. The piece frames the tradeoff: Amazon gives away algorithms to drive efficiency; Trade Desk builds controlled integrations to reward trusted supply.
A major platform (Amazon) released an open technical tool and a major DSP (The Trade Desk) outlined alternative verification tooling; both approaches can materially affect programmatic supply-path efficiency and SSP economics.

Trade Desk Still Dominant but Advertisers Shop Around
The Trade Desk remains the largest demand-side platform (DSP) with strong 2025 financials — $2.9 billion revenue, 47% margins and $1.3 billion cash — but advertisers and agencies are increasingly reallocating spend. Interviews with more than ten ad executives describe shifts toward Amazon DSP, retail media networks, direct buys and other DSPs driven by cleaner measurement, integrated retail-video offerings and account/service concerns. The Trade Desk says it is responding with head-to-head testing (claiming better reach and cost versus Amazon in tests), joint business plans (JBPs) and a reorganization into Specialized Business Units. Industry voices note the company has eased gated features and changed commercial behavior, while account instability and competitive multi-year deals from platforms are opening the door for rivals. The piece frames a broader risk of DSP commoditization as API/AI lowers switching costs.
Trade Desk Unveils OpenTTD; FirstPartyCapital Offers Alternative
On March 3, 2026, two industry moves signaled competing strategies to reduce dependence on dominant ad platforms. FirstPartyCapital (FPC) announced a corporate innovation model that combines embedded engineering, market intelligence and equity co-investment to help brands, agencies and publishers access alternative ad‑tech infrastructure. Six hours later The Trade Desk launched OpenTTD, a unified partner integration portal that centralizes partner access and intelligence. The article contrasts those efforts with Amazon’s growing advantage — Amazon Ads grew 22% in Q4 2025 to $21.3B and the company leverages exclusive inventory, purchase-linked attribution and discounted DSP fees to capture demand. The author frames a possible future of a bifurcated ad‑tech economy: companies embedded in platform intelligence versus those building independent infrastructure through models like FPC’s.
Trade Desk Faces Programmatic Power Struggle
Major agencies including Dentsu and WPP have pulled back spend from The Trade Desk’s OpenPath offering amid concerns about hidden fees and transparency; Publicis Groupe stopped recommending TTD after a third-party audit. The Trade Desk is also changing how it pays identity providers such as LiveRamp and Experian. The episode frames the dispute as part of a broader industry shift in which DSPs, SSPs and agency holding companies vie to become a single unified ad platform (UAP). Competitors named include Pubmatic, Magnite and Index. The Trade Desk has seen executive departures (including Melinda Zurich, Matthew Henick and Ian Colley) and a stock decline this year, but posted nearly $3 billion in revenue last year and continues pushing direct-to-brand/publisher strategies via OpenPath and its AI-driven Kokai platform.
