The Trade Desk is a demand-side platform for buying and measuring advertising across the open internet. Kokai is the platform experience that brings campaign planning, activation, optimization and measurement into a more connected workflow.
The practical question for advertisers is not whether Kokai has more features. It is whether teams can use its audience, identity, inventory, AI and measurement tools to make better decisions without giving up control.
Quick answer: The Trade Desk DSP helps advertisers buy premium omnichannel media across the open internet. Kokai is its current media-buying platform, while Koa is the AI layer that evaluates opportunities, supports audience and campaign decisions, and optimizes toward advertiser-defined outcomes. Buyers still set goals, targeting, exclusions, channels, measurement and operating rules. Kokai works best when those inputs are clear.
AdGeeks can map the platform to your markets, audiences, inventory and measurement requirements, then structure the activation workflow.
What is The Trade Desk DSP?
The Trade Desk is an independent programmatic buying platform. The company says it does not own or operate media. Its role is to help advertisers evaluate and buy inventory across the open internet while maintaining visibility and control over data, placements and optimization.
The platform brings together four core capabilities:
Audience-first planning: first-party, retail and third-party data can be activated through one buying workflow.
Omnichannel inventory: buyers can plan across CTV, online video, display, audio, native, mobile and digital out-of-home.
AI-driven decisioning: Koa evaluates large volumes of impression opportunities and supports bidding, pacing and delivery decisions.
Outcome-based measurement: advertisers can onboard conversion data or use independent partners for outcomes such as brand lift, foot traffic and sales.
What is Kokai?
Kokai is The Trade Desk's media-buying platform and workflow. It connects audience strategy, identity, inventory, optimization and measurement. Recent official resources also use the name Kokai Zuma for the current platform release cycle.
Kokai should not be understood as an autopilot that replaces the trader. It is better viewed as a decision environment. The platform can surface patterns, rank opportunities and recommend actions. The advertiser still defines the business goal, guardrails and acceptable tradeoffs.
Current capability note: The Trade Desk says Koa's conversational experience is in closed beta as of October 2026. Not every capability described on the company's roadmap is generally available. This guide separates current platform functions from previewed features.
The Trade Desk, Kokai and Koa: how they fit together
Layer | What it is | Primary job | Advertiser responsibility |
|---|---|---|---|
The Trade Desk | The company and demand-side platform | Access to programmatic tools, partners, data and open-internet inventory | Confirm commercial terms, access model, markets and governance |
Kokai | The media-buying platform experience | Plan, activate, optimize and measure campaigns in a connected workflow | Build the account, campaign, audience and reporting structure |
Koa | The Trade Desk's advertising AI | Evaluate opportunities and support targeting, bidding, pacing, delivery and insights | Set goals, inputs, controls, exclusions and review rules |
Audience and identity capabilities
The Trade Desk's audience proposition combines advertiser data, data partners and identity tools. The platform describes an audience-first approach that prioritizes strong signals rather than treating every segment equally.
First-party data with Galileo
Galileo is The Trade Desk's first-party data onboarding and activation framework. It can help advertisers use customer data across the open internet, subject to consent, partner setup, match rates and applicable privacy requirements.
Retail data
The platform provides access to a marketplace of retail data partners. Retail audiences can support prospecting, category insight and closed-loop outcome analysis when the selected partner and advertiser have the required permissions.
Third-party data
Behavioral, demographic and interest data from approved providers can extend reach. Buyers should review methodology, freshness, geography, overlap and cost before adding a segment to the plan.
Durable identity
The Trade Desk supports identity approaches designed for the open internet, including Unified ID 2.0 and regional alternatives. Identity improves addressability and cross-device planning only when publishers, data owners and advertisers participate with the right permissions.
Omnichannel inventory and campaign groups
Kokai is designed for media plans that span several channels. A buyer can coordinate CTV, video, audio, display, native, mobile and digital out-of-home from one platform instead of treating each channel as a separate campaign universe.
Channel | Typical role | Planning focus |
|---|---|---|
CTV | High-attention reach and brand storytelling | Premium supply, household reach, frequency and completed views |
Online video | Education and consideration | Creative length, player environment, completion and incremental reach |
Display and native | Scalable prospecting, reinforcement and response | Viewability, context, creative variation and conversion path |
Audio | Incremental reach during listening moments | Distinctive audio assets, frequency and device context |
Digital out-of-home | Location-based reach and physical-world visibility | Venue, time, audience movement and measurement feasibility |
The omnichannel campaign group dashboard provides a consolidated view across channels. The Trade Desk says it can help buyers compare performance, review conversion paths and enable omnichannel optimizations.
How Koa supports campaign decisions
Koa evaluates a large volume of impression opportunities across the open internet. It is designed to optimize toward the outcome specified by the advertiser, not a media property owned by the platform.
The AI can support:
audience modeling and reach expansion;
impression prioritization based on campaign relevance;
bidding, pacing and delivery adjustments;
cross-channel optimization;
measurement insights and performance diagnostics.
Good inputs still matter. A vague conversion event, mixed campaign goals or weak audience taxonomy gives the system a weak target. Before enabling aggressive optimization, verify the conversion signal, attribution logic, budget constraints and minimum learning period.
Human control inside an AI workflow
The Trade Desk positions Koa as a co-pilot. Traders provide the strategy and context that the model cannot see. Kokai includes tools that let teams express those judgments.
Bid factoring
Bid factoring allows a trader to raise or lower bids where internal knowledge suggests additional value. This is useful when the platform lacks a relevant business signal, such as inventory quality known from a direct publisher relationship or a regional event.
Guardrails and permissions
The company says Koa includes visibility into recommendations and performance drivers, plus safeguards and permissions. Teams should decide where AI advises, where it can take action and where manual approval remains mandatory.
Change logs and review cadence
Record major changes to goals, audience definitions, bid factors, exclusions and measurement. Review the reason for each change before crediting or blaming AI for the result.
Path-to-conversion reporting
Path-to-conversion reporting shows the sequence of campaign touchpoints that preceded a conversion. It helps teams move beyond the last interaction and examine how channels work together.
Use it to answer practical questions:
Which combinations of CTV, video, audio and display appear before the target action?
Does one channel introduce customers while another closes the journey?
Where is frequency concentrated without adding a useful touchpoint?
Which paths deserve a controlled test in the next planning cycle?
Path reports show association, not automatic causation. Validate the insight with experiments, holdouts or incrementality studies where possible.
Measurement and optimization
The Trade Desk allows advertisers to onboard their own conversion data and connect with independent measurement providers. The partner marketplace includes options for brand lift, foot traffic, in-store sales and other outcomes.
A complete measurement design should include:
one primary business outcome and supporting funnel signals;
conversion ownership, quality checks and deduplication;
attribution windows and identity coverage;
brand, sales or incrementality studies where relevant;
a reporting cadence that respects conversion lag;
rules for moving budget across channels.
The platform dashboard helps manage delivery. The measurement plan determines whether delivery created value.
OpenPath and supply-path decisions
OpenPath is The Trade Desk's direct connection between participating publishers and buyers. The company says it is intended to improve transparency and reduce intermediaries in the supply chain.
OpenPath should sit inside a broader supply-path strategy. Compare direct and exchange paths by publisher access, auction dynamics, fees, data transparency, quality and performance. Do not assume the shortest path is automatically the best path for every impression.
Who should consider The Trade Desk and Kokai?
The platform is a strong consideration for advertisers and agencies that need broad open-internet access, advanced omnichannel planning, independent measurement choices and hands-on trading control.
It may be less suitable when the advertiser needs a simple self-serve product, has limited conversion data, lacks creative for multiple channels or cannot support regular optimization and governance. Platform access, service model and commercial requirements should be confirmed directly or through an authorized partner.
A practical launch framework
Phase | Focus | Key outputs |
|---|---|---|
1. Strategy | Outcome, audience and channel roles | Business brief, audience architecture, inventory plan and measurement design |
2. Build | Data, taxonomy and controls | Conversion validation, naming rules, campaign groups, exclusions, bid factors and approvals |
3. Launch | Delivery and quality | Pacing checks, supply review, audience overlap, creative diagnostics and frequency control |
4. Learn | Cross-channel contribution | Path-to-conversion review, partner measurement, test results and budget recommendation |
Common mistakes
Calling Kokai fully autonomous. The platform still depends on goals, data, controls and trader judgment.
Mixing objectives inside one optimization target. Awareness and conversion tactics need distinct success criteria.
Adding channels without a role. Omnichannel does not mean every channel belongs in every plan.
Using bid factors without a hypothesis. Manual adjustments should express real business knowledge.
Reading conversion paths as proof of causation. Use controlled measurement to validate contribution.
Assuming previewed AI features are available. Check current account and market access before planning workflows around closed-beta capabilities.
