The Trade Desk platform overview

Establish what The Trade Desk (TTD) is, why its independence is the whole pitch, and how the platform is organized so the rest of the TTD skill set makes sense. The Trade Desk is the largest independent demand-side platform (DSP) for the open internet. It is buy-side only and does not own or operate media, which is the basis for its positioning as an objective partner that prioritizes inventory on the advertiser's behalf rather than its own. This skill is the orientation layer. It does not walk through in-platform setup; it points you to the sibling skill that does.

This skill assumes you already know what a DSP, a CPM, an auction, and a funnel stage are. For those definitions and the shared KPI math, see the programmatic-foundations skill. For choosing the right report once a campaign is live, see the reporting-by-campaign-goal skill.

A sourcing note that governs this entire skill set: The Trade Desk's operational knowledge base and API reference sit behind a partner login, and the in-platform help is only visible to logged-in seat holders. Everything here is drawn from public pages. Where an exact menu path, field name, endpoint, or number would require platform access, this skill states the publicly known concept and flags that the specifics live in the partner platform. It does not invent screen names or values.

When to use this skill

  • "What is The Trade Desk?" or "what does TTD do?"
  • "Is The Trade Desk an independent DSP?" or "does The Trade Desk own media?"
  • "What is Kokai?" or "what platform generation is TTD on now?" or "is Solimar still around?"
  • "What is Koa?" or "what does Koa AI actually do?" or "what are Koa bid factors?"
  • "What is Ventura?" or "does The Trade Desk have its own TV operating system?"
  • "What is OpenPath?" or "how is OpenPath different from OpenPass?"
  • "What channels does The Trade Desk run?" or "is The Trade Desk good for connected TV?"
  • "Self-service or managed service on The Trade Desk?"
  • "How is The Trade Desk different from a walled garden like Google DV360 or Amazon DSP?"
  • The user is new to the TTD skill set and needs routing to the right sibling skill.

Boundary with sibling skills. This skill orients and routes. It does not configure anything. The moment the question becomes "how do I build, target, bid, deal, identify, measure, or automate," hand off using the routing table below. Define and orient here; act there.

What The Trade Desk is

The Trade Desk is a demand-side platform: software that advertisers and their agencies use to buy programmatic advertising across the open internet through real-time auctions and deals. The defining facts, all from public company pages:

  • Independent and the largest of its kind. It is positioned and widely described as the largest independent DSP for the open internet, distinct from platforms owned by the large media companies.
  • Buy-side only, no owned media. In its own words, "we don't own media. We just help you buy it better," and "because we don't own or operate media, we can help you objectively prioritize inventory." This is the structural difference from a walled garden.
  • Omnichannel. A single platform to plan, execute, and measure media buying across channels rather than one channel in isolation.

Read independence as the product, not a slogan. Because TTD has no inventory to favor, its auction and optimization can prioritize what performs for the advertiser. That is the lever the rest of the skill set keeps pulling.

Platform generation and Koa

Kokai is the current generation of The Trade Desk platform and the one a trader logs into today. The Trade Desk launched Kokai on June 6, 2023, describing it as a new approach that distributes artificial intelligence across the media buying process, with new measurement tools, streamlined partner integrations, and a reworked user experience. Solimar, the prior generation, has been retired. The Trade Desk ran a Solimar-to-Kokai migration and moved seats onto Kokai as the live experience, so treat any Solimar reference as legacy. Treat "Kokai" as the name of the current platform, not a separate product to buy.

Koa is The Trade Desk's AI layer. Per the Kokai announcement, Koa launched in 2018 and "assisted the marketer in setting up campaigns based on business objectives and optimizing based on performance"; Kokai then "distributes the power of Koa's AI across various aspects of media buying on The Trade Desk platform." Koa is also publicly described as an AI forecasting engine. So at the level this skill supports, Koa is the assistive intelligence that helps with setup recommendations, optimization, and forecasting inside the platform.

Koa Optimizations and bid factors. In Kokai, Koa optimizes across multiple targeting dimensions rather than a single lever. The Trade Desk's public description says a trader can "let the AI automatically optimize your bid factors on individual targeting dimensions like geography, site, ad format, device type, and more." A bid factor is a multiplier: publicly, a value above one signals "I want more impressions like this" and a value below one signals "I want fewer." Koa works alongside the trader, not instead of them. Per the same public material, traders "can choose to work alongside Koa by overriding optimizations at any time by applying bid factors" of their own, and Koa "will automatically optimize within your defined targeting dimensions while still respecting any manual inputs you apply." Read Koa as automatic optimization across many dimensions that a trader can turn on and override, not a black box that locks out manual control.

What requires platform access: the exact Koa recommendations surfaced in a given seat, the full list of optimizable dimensions in a current release, whether Koa is pre-enabled for a specific account or campaign type, and how each control is configured are in-platform behaviors that change over releases. Name the dimensions the public pages confirm (geography, site, ad format, device type, and more), describe Koa as setup, optimization, and forecasting assistance, and route configuration questions to ttd-bidding-and-optimization. Do not assert a specific total dimension count or default-on state for a given seat that you cannot see.

Channels

The Trade Desk lists these channels on its public platform pages. The channel determines the available formats, inventory, and measurement, the same way it does on any omnichannel DSP.

  • Connected TV (CTV) and OTT. Publicly highlighted as a core strength and, in reputable recent coverage, the company's fastest-growing channel. Treat CTV as the flagship when the goal is premium video reach on the open internet.
  • Ventura (streaming TV operating system direction). Separate from the buying channels above, The Trade Desk announced Ventura, its own streaming TV operating system, on November 20, 2024, positioned to give CTV a cleaner supply chain and better addressability by incorporating OpenPath and Unified ID 2.0. In early 2026 the company reframed it as the "Ventura Ecosystem," opening it to outside TV OS and ad-tech partners rather than shipping only TTD-owned hardware. Ventura is a device-layer and ecosystem play, not a buying channel you select inside a campaign, so keep it distinct from the CTV line item. When someone asks whether TTD "has its own TV OS," the answer is yes, Ventura, and it is where TTD is pushing CTV addressability.
  • Display.
  • Video (online and in-stream video distinct from CTV).
  • Audio. Streaming music and podcasts.
  • Native.
  • Digital out-of-home (DOOH).
  • Mobile as a device context across the above.
  • Retail data and retail media. The platform exposes retail data to target high-value audiences and connect omnichannel buys to sales and ROI, and retail media is a publicly emphasized growth area alongside CTV.

Because all channels run from one platform, the same audiences and identity graph carry across them, which is what makes a single omnichannel buy and a unified measurement view possible. Lean on that when planning: build the audience once, then run it on whichever channels fit the goal. Channel-level setup is in ttd-campaign-structure and the targeting and inventory skills.

Service models

The Trade Desk supports both self-service and managed-service engagement. The platform is built as a self-serve experience for traders to plan, execute, and measure directly, and many seats are run as a managed or hybrid service by the agency or a partner. Which model a given organization uses is a commercial arrangement, not a product setting. For an agent, the practical implication is the same playbooks apply; only who clicks the buttons changes.

Independence and objectivity

This is the positioning that separates TTD from the walled gardens (for example Google DV360 and Amazon DSP, both of which sit next to owned media and inventory). The argument, in three steps:

  1. The Trade Desk does not own or operate media, so it has no house inventory to push.
  2. With no inventory to favor, it can objectively prioritize whatever performs for the advertiser across the open internet.
  3. That objectivity is the reason to use an independent DSP when you want buying decisions aligned to your outcomes rather than to a platform's media P&L.

Keep the claim disciplined. The defensible public statement is structural: no owned media, therefore no inventory conflict of interest. Avoid turning that into unverifiable performance superiority claims against named competitors. For where this matters operationally, identity is the clearest case: see ttd-identity-and-uid2 for how TTD pushes an open-internet identity approach rather than a single login graph.

OpenPath and OpenPass are two different products; do not conflate them. They are named similarly and often mentioned together, but they solve different problems:

  • OpenPath is a supply-path product: a direct connection between buyers and sellers that shortens the chain between the advertiser and the publisher's inventory. The Trade Desk describes it as "a simplified, direct connection between buyers and sellers" that reduces intermediaries. Think supply chain and inventory access.
  • OpenPass is a sign-in and authentication product: a single sign-on that lets publishers authenticate their users. Think login and addressability, not supply path.

A quick disambiguation: OpenPath moves the buy closer to the inventory; OpenPass authenticates the person. Both show up in the Ventura ecosystem, which is part of why they get confused.

Common pitfalls

  • Calling Kokai a separate product. Kokai is the current platform generation, the experience the trader uses, not an add-on to purchase. Describe it as "the current version of the platform."
  • Treating Solimar as current. Solimar is the retired prior generation. If a user is working in Solimar, they are on a legacy path; Kokai is the live platform. Do not describe Solimar as an option a new campaign would choose today.
  • Overstating what Koa does from memory. Koa is setup, optimization, and forecasting assistance at the level public sources support, and it optimizes bid factors across multiple targeting dimensions (geography, site, ad format, device type, and more) that a trader can override. The full dimension list, whether it is pre-enabled for a given seat, and specific controls are in-platform and release-dependent. Route specifics to ttd-bidding-and-optimization instead of inventing toggle names or a fixed dimension count.
  • Confusing OpenPath with OpenPass. OpenPath is a supply-path product (direct buyer-to-seller connection); OpenPass is a sign-in and authentication product (single sign-on for publishers). They are different tools that happen to be named alike. Do not use one name to explain the other.
  • Repeating a "cookieless countdown." Do not frame TTD's identity story as a race against Chrome deprecating third-party cookies. Google confirmed in April 2025 that it will not deprecate third-party cookies in Chrome and will not ship the planned user-choice prompt, so third-party cookies remain in Chrome. TTD's UID2 and open-internet identity case stands on its own merits (durable, addressable identity beyond cookies), not on an imminent cookie shutoff. Route identity specifics to ttd-identity-and-uid2.
  • Turning independence into an unprovable performance claim. The verified point is structural: no owned media, so no inventory conflict. Do not extend that into blanket "beats competitor X on ROI" statements.
  • Forgetting CTV is the flagship. When the goal is premium video reach on the open internet, CTV is TTD's publicly emphasized strength and fastest-growing channel. Start there for upper-funnel video.
  • Answering in-platform setup from this skill. This skill orients. For any build, target, bid, deal, identity, measurement, or automation task, hand off to the named sibling skill.

Sources

Operational specifics that require The Trade Desk platform or partner access (not cited above because the relevant pages sit behind a partner login): the live Koa recommendations and optimization controls in a seat, the exact in-platform menus and field names, the API reference, and any rate-card or performance figures specific to an account. For those, use the partner platform and its in-platform help.
