The Trade Desk Launches Kokai Zuma With AI Agent Ask Koa: What Advertisers Need to Know
On August 27, 2026, The Trade Desk unveiled Kokai Zuma — the largest update to its Kokai programmatic advertising platform since Kokai launched in 2023. The centerpiece is Ask Koa, a conversational AI agent that routes advertiser queries through six specialized back-end sub-agents, from campaign creation to mid-flight diagnostics. The announcement was published simultaneously via The Trade Desk press room and covered in depth by AdExchanger.
Zuma is not a new product — it is a generational evolution of the existing Kokai platform built around three pillars: agentic AI (Ask Koa), a redesigned UX, and simplified measurement. For programmatic buyers and digital marketing teams that run The Trade Desk alongside other AI-powered ad platforms like ChatGPT Ads Manager, understanding what Zuma changes — and what it does not — is now part of the job.
What is Ask Koa?
Ask Koa is a single conversational interface inside the Kokai dashboard that routes user requests to six specialized backend sub-agents depending on intent:
- Help and search — documentation lookup and feature discovery.
- Campaign creation — reads uploaded media plans, flags inconsistencies, and pre-fills campaign settings.
- Mid-flight performance insights — surfaces pacing alerts, CTR anomalies, and CPA trends without manual report-building.
- Troubleshooting — diagnoses delivery issues; automated fixes for common problems are described as “coming later.”
- Frequency optimization — currently in closed beta; uses AI-dynamic frequency caps to reduce wasteful ad repetition.
- Audience building — constructs audience segments from natural-language descriptions.
At launch, Ask Koa is in closed beta and rolling out to all users by the end of 2026. The Trade Desk has also published an Open Agentic Kit — an API that lets third-party AI tools route queries through Koa’s agent infrastructure, positioning Koa as a platform layer rather than a walled tool.
Performance data: the 32% CPA improvement
The headline metric The Trade Desk shared at launch is a 32% average improvement in cost-per-acquisition across 62 campaigns with Koa Optimizations enabled. The company also claims the platform now analyzes more than 20 million ad impressions per second.
The caveats are worth understanding before citing this number internally:
- The 62-campaign sample reaches statistical significance (p < 0.05), but the sample is modest.
- The comparison is upgraded Koa model vs. prior Koa model, not AI-on vs. AI-off. Advertisers who were already using Koa Optimizations may see smaller gains than the headline implies.
- This is platform-supplied data. No independent third-party audit has been published.
That said, 32% CPA improvement on a like-for-like model comparison is a meaningful data point — treat it as a directional signal rather than a guaranteed outcome, and benchmark against your own account’s baseline once you gain access to the beta.
The UX overhaul: what changed
Zuma replaces Kokai’s “periodic table” interface — the visual layout that divided ad buying into element-style tiles — with a more conventional dashboard format designed around pacing and performance visibility. The periodic table is no longer the default view.
Other UX changes in the Zuma release:
- Applied Settings view: A consolidated panel showing every campaign parameter with red (delivery blocker) and yellow (AI recommendation) labels, making it faster to identify the highest-impact issues in an account.
- Bulk editing with impact preview: Apply changes across hundreds of ad groups simultaneously and see a projected impact before confirming.
- Audience Unlimited: AI-powered audience expansion that draws on more than 70% of global data providers — described as the broadest reach layer The Trade Desk has offered within a single activation.
One client quote that reflects the practical reaction from media buyers: Tom Swierczewski, VP at Goodway Group, noted that the UX evolution “returns control we had in Solimar” — a reference to The Trade Desk’s earlier platform architecture. That framing suggests the Zuma UX is designed to re-earn trust from practitioners who found the Kokai periodic table disorienting.
Simplified measurement
Measurement was the third pillar of the Zuma announcement. The headline change is a reduction in lift study setup time from the previous 5–7 day window to 48 hours — a meaningful operational improvement for teams that run frequent campaigns and need faster feedback loops.
Additional measurement features in the Zuma release:
| Feature | What it does | Status |
|---|---|---|
| GeoLift | Incrementality testing for brick-and-mortar advertisers without third-party panel dependency | Available at launch |
| Nielsen IQ partnership | Automated lift studies for CPG advertisers with NielsenIQ data integration | Available at launch |
| Lucid brand lift | One-click brand lift studies through Lucid’s survey panel | Available at launch |
| Lift study setup | Full configuration in 48 hours, down from 5–7 days | Available at launch |
Faster lift setup matters most for advertisers running quarterly flight cycles who previously had to choose between launching a campaign quickly and launching it with measurement in place. The 48-hour setup is designed to eliminate that tradeoff.
How Zuma fits the broader AI advertising shift
Kokai Zuma is arriving at a moment when AI-mediated ad buying is converging across every major platform. AI search advertising is expanding rapidly, with platforms racing to position conversational AI not just as an inventory channel but as an ad operations layer.
The differentiating angle for The Trade Desk is the Open Agentic Kit. By exposing Koa’s sub-agent infrastructure as an API, The Trade Desk is making a bet that the future of programmatic buying will involve external AI orchestration tools — custom dashboards, agency-built tools, AI-first attribution vendors — routing commands through Koa rather than forcing all workflows to live inside the Kokai UI.
This approach is structurally different from Google’s and Meta’s walled-garden automation models, where AI optimization happens inside the platform and external tools interact only at the reporting layer. Whether the open-agent bet pays off depends on whether third-party developers actually build against the kit — something we will know more about by Q1 2027.
For digital marketing teams already navigating Google Ads’ September AI Max auto-upgrade, Zuma’s opt-in posture is a notable contrast. The Trade Desk is extending access gradually through a closed beta rather than applying changes to accounts automatically.
What to do now
Most advertisers will not have immediate access to Ask Koa in closed beta. But there are preparation steps that apply regardless of when your account gets access:
- Register interest in the Koa beta through your Trade Desk account team or the Zuma resource page. Early access cohorts will be shaped by account spend and advertiser type.
- Audit your current Koa Optimization settings. If you are not already using Koa’s existing optimization features, a baseline review will give you comparison data when the Zuma model rolls out.
- Document your current lift study setup workflow. The 48-hour setup improvement is only useful if your team has a clear process for when to trigger a lift study. Standardizing that decision criteria now means you can take advantage of the speed immediately.
- Evaluate the Open Agentic Kit if you use custom tooling. If your agency or team maintains proprietary dashboards that currently pull data from The Trade Desk API, the Agentic Kit documentation is worth reading to understand whether routing queries through Koa could reduce your tooling maintenance burden.
- Watch the search term reports — particularly if Audience Unlimited launches in your account before Ask Koa. Expanded reach layers across 70%+ of global data providers can surface new audience segments worth testing explicitly in other campaign types.
Frequently asked questions
When does Ask Koa become available to all Trade Desk advertisers?
As of the August 27 announcement, Ask Koa is in closed beta. The Trade Desk has indicated a full rollout to all Kokai clients by the end of 2026, but no specific date has been given. Access will expand in waves; contact your account team to register interest for early access.
Does Kokai Zuma replace Kokai entirely, or is it an update?
Zuma is an update to the existing Kokai platform, not a separate product. Existing Kokai clients do not need to migrate — Zuma features are being rolled into the platform they already use. The periodic table interface remains available for accounts that prefer it; it is simply no longer the default view.
What is the Open Agentic Kit and who should use it?
The Open Agentic Kit is an API that allows third-party AI tools, agency dashboards, and external software to route programmatic buying commands directly through Koa’s specialized sub-agents. It is designed for agencies and technology teams with custom tooling rather than for individual advertisers using the Kokai UI directly.
How does the 32% CPA improvement apply to my account?
The 32% figure is an average across 62 campaigns comparing the upgraded Koa model to The Trade Desk’s prior Koa model. Your results will depend on campaign type, vertical, audience maturity, and whether you were already using Koa Optimizations. Use it as a directional indicator, not a guaranteed outcome, and measure against your own account’s baseline once you gain beta access.
Does Zuma affect pricing or contract terms with The Trade Desk?
No pricing changes have been announced alongside the Zuma release. The Trade Desk has framed Zuma as a platform evolution included for existing Kokai clients. If your contract is up for renewal, it is worth confirming with your account team whether beta access to Ask Koa is covered under existing terms or will require a separate arrangement.
