The Trade Desk vs Halliard: Which Media Planning Tool Is Right for You? (2026)

When someone says “independent DSP,” The Trade Desk is almost always the next word. The company processed $12.4 billion in gross spend in 2025 and generated $2.9 billion in revenue — an 18% year-over-year increase that tells you the open internet programmatic market is still growing, and The Trade Desk is capturing most of it. The Kokai AI platform analyzes 15 million ad opportunities per second. UID2 is becoming the identity standard for the cookieless web. These aren’t claims — they’re audited results.

Halliard is a different tool solving a different problem. It’s not trying to be a DSP. It’s the operating system for modern media teams: the planning layer, the cross-channel R+F engine, the workflow that connects strategy to execution across 18+ channels. The Trade Desk is where the buy happens; Halliard is where the plan gets built.

Whether you need one, the other, or both depends on what kind of media team you are.

What Is The Trade Desk?

The Trade Desk is the leading independent demand-side platform for programmatic advertising across the open internet. Founded in 2009, the platform gives agencies and brands access to premium inventory without the walled-garden conflicts of interest embedded in Google and Meta’s self-serve platforms. The independence claim is genuine — The Trade Desk doesn’t own media, doesn’t operate a publisher network, and doesn’t compete with the advertisers it serves.

The Kokai AI platform, launched in 2023, is the current-generation intelligence layer. It analyzes 15+ million ad opportunities per second and applies machine learning to bidding, audience expansion, and campaign optimization in real time. In 2025, The Trade Desk reported $2.9B in FY revenue and continued to grow its market position as programmatic budgets shifted from closed ecosystems to the open internet.

Pricing is enterprise: 15–20% of media spend with a minimum quarterly commitment of $100,000+. That threshold means The Trade Desk is not accessible for smaller agencies or brands with limited programmatic budgets — a constraint the company acknowledges by design.

What Is Halliard?

Halliard is a media planning and buying platform built by Matthew Jacobs — 15+ years across Starcom, Dentsu (SVP Product), Amazon DSP (Senior PM), and Paramount (Senior Director). The platform’s premise is that independent agencies and in-house teams managing $10M to $500M+ in annual spend have been underserved by both the enterprise infrastructure built for holding companies and the lightweight tools built for freelancers.

Halliard’s three core differentiators are: a proprietary 10,000-person panel across 210 DMAs for cross-channel reach and frequency analysis at the planning stage; agentic buying that completed the industry’s first autonomous plan-to-buy transaction via PubMatic MCP in December 2025; and a full plan-to-proof workflow that retains institutional knowledge across every campaign.

Halliard starts free — no credit card required. For a platform with enterprise-grade capabilities, the accessibility is genuinely notable.

Comparison Table

Where The Trade Desk Wins

Scale and infrastructure. $2.9 billion in annual revenue and $12.4 billion in gross spend isn’t a number you manufacture. The Trade Desk has built the infrastructure to handle complex, high-volume programmatic operations with a reliability that only comes from processing at genuine scale. Agencies running tens of millions in programmatic spend benefit from this flywheel.

Kokai AI’s real-time optimization. Analyzing 15 million ad opportunities per second isn’t a benchmark you reach by running machine learning models on historical data. Kokai’s real-time bidding intelligence means the platform is continuously making micro-optimization decisions that compound into material performance gains over the life of a campaign.

UID2 and the cookieless future. The Trade Desk’s Unified ID 2.0 initiative has become one of the most widely adopted identity standards for the post-cookie web. UID2 allows privacy-compliant audience targeting without third-party cookie dependency — and The Trade Desk’s position as its primary architect gives their platform first-mover advantage as Chrome’s deprecation timeline evolves.

Open internet positioning. For advertisers who want to invest in the open internet without the walled-garden dependency risks of Google and Meta, The Trade Desk is the platform of record. The independence from publisher ownership is a structural advantage that gets more valuable the more programmatic regulation and antitrust scrutiny increases.

Premium inventory access. The Trade Desk’s relationships with premium publishers, streaming platforms, and private marketplace curators give buyers access to inventory environments that smaller DSPs can’t match.

Where Halliard Wins

Planning-first workflow. The Trade Desk begins at the point of execution — the bid. Halliard begins at the point of strategy — the plan. For media teams where the most important decisions happen in the weeks before a campaign launches, not the hours after, the planning-first architecture is genuinely more useful.

Cross-channel R+F without a separate data contract. To do cross-channel reach and frequency analysis at the planning stage with The Trade Desk, you need a third-party data provider and a separate analytics workflow. Halliard’s proprietary panel — 10,000 people across 210 DMAs — does this natively. For independent agencies that can’t justify enterprise data subscriptions, this capability at Halliard’s price point is a significant difference.

Accessible entry point. A $100,000 quarterly minimum is not a threshold most independent agencies or in-house teams can clear. Halliard’s free plan removes the financial barrier to evaluating and adopting modern media planning tooling. The economics are different by design: Halliard is built for agencies that The Trade Desk can’t serve.

Agentic buying that originates from the plan. The Trade Desk’s Kokai AI automates within the programmatic execution layer — optimizing bids, allocating budget, expanding audiences. Halliard’s December 2025 PubMatic MCP transaction automated the step before that: the execution of the buy as determined by the plan. These are sequential steps in the workflow, and Halliard is automating the upstream one.

Multi-channel including walled gardens. The Trade Desk’s independence from Google and Meta is a feature for brands de-risking their platform dependency — but it’s also a constraint. The Trade Desk does not buy on Google Search, Meta, or TikTok. Halliard connects to all of them, which is where a significant share of most media plans still live.

Feature-by-Feature Breakdown

Audience Targeting

The Trade Desk integrates 500+ first-party and third-party data sources, offers UID2 for cookieless targeting, and uses Kokai AI for lookalike modeling and cross-device resolution. The audience infrastructure is built for sophisticated programmatic targeting at scale.

AI Capabilities

The Trade Desk runs Kokai AI across the live bidding environment — 15M+ ad opportunities analyzed per second, with automated bid optimization, audience expansion, and performance prediction built into the buying workflow.

Halliard applies AI through a conversational assistant for planning questions, what-if scenario modeling, marketing mix analysis, and the agentic buying workflow that executed the first autonomous plan-to-buy transaction in December 2025.

Channels

The Trade Desk covers the open internet programmatically: display, video, CTV, audio, DOOH, and native. It does not support Google Search, Meta, or TikTok advertising directly.

Halliard connects to 18+ channels including Google, Meta, TikTok, Spotify, Netflix, YouTube, Twitch, Hulu, and linear TV — a broader multi-channel scope that includes walled gardens.

Pricing

The Trade Desk charges 15–20% of media spend with a $100K+ quarterly minimum. Total cost scales directly with spend volume.

Halliard offers a free plan for individual planners with no credit card required, and premium tiers for teams managing larger portfolios.

Best Fit Scenarios

Choose The Trade Desk if:

• Programmatic buying on the open internet represents a large share of your overall media investment
• Your quarterly programmatic budget clears $100K, making the minimum commitment viable
• Real-time AI optimization across 15M+ ad opportunities per second matters for your campaign performance
• Cookie-free audience targeting via UID2 is a strategic priority
• You’re intentionally diversifying away from Google and Meta’s walled garden environments
• You need access to premium private marketplace deals at scale

Choose Halliard if:

• Your media mix spans walled gardens and open internet — Google, Meta, TikTok, and programmatic together
• Cross-channel reach and frequency analysis at the planning stage drives your strategic decisions
• You’re an independent agency or in-house team where a $100K quarterly minimum isn’t realistic
• You want to start with a free plan and evaluate before any financial commitment
• Institutional knowledge retention across campaigns matters for your team’s continuity
• You want to understand what agentic plan-to-buy execution looks like in production

A Note on Where These Platforms Fit in the Same Agency

The most common question when comparing a DSP and a planning platform is whether you need one or both. For agencies already using The Trade Desk for programmatic execution, Halliard can serve as the upstream planning layer — where cross-channel strategy, budget allocation, and reach analysis happen before any programmatic buy is submitted. In that architecture:

• Halliard handles cross-channel planning, R+F modeling, approval workflows, and performance tracking
• The Trade Desk handles programmatic execution within the open internet
• Platform-direct buys on Google, Meta, and TikTok sit alongside both

This isn’t a zero-sum comparison. Teams that treat planning and execution as separate problems — requiring separate, purpose-built tools — tend to have cleaner workflows than teams that try to do both inside a DSP that wasn’t designed for strategic planning.

FAQ

Does The Trade Desk have a minimum spend? Yes. The Trade Desk requires a minimum quarterly commitment of approximately $100,000 in media spend, plus a 15–20% platform fee on that spend. This makes the platform inaccessible for smaller agencies and brands with limited programmatic budgets. Halliard offers a free plan with no minimum.

Does Halliard compete with The Trade Desk for programmatic inventory? No. Halliard is a planning and workflow platform that integrates with channel platforms (including DSPs) for execution. It’s not a bidding platform competing for inventory. The relationship is complementary: Halliard handles upstream planning, The Trade Desk handles programmatic execution.

What is UID2 and why does it matter? Unified ID 2.0 (UID2) is an open-source identity framework developed by The Trade Desk that enables privacy-compliant audience targeting without third-party cookies. It uses encrypted, hashed email addresses as the identity token. As Chrome continues to reduce third-party cookie support, UID2 provides a targeting methodology that doesn’t depend on cookies while maintaining user privacy controls.

How does Kokai AI compare to Halliard’s AI capabilities? Kokai AI operates in the live bidding environment — analyzing 15M+ ad opportunities per second for real-time campaign optimization. Halliard’s AI operates in the planning environment — conversational analysis, scenario modeling, and the agentic buying workflow that bridges plan to executed transaction. These are AI applications solving different problems at different stages of the media workflow.

Can I use The Trade Desk and Halliard together? Yes. Several agencies use Halliard for cross-channel planning and R+F analysis, then use The Trade Desk (or other DSPs) for programmatic execution. Halliard’s integrations and export workflows connect the plan to the buying platform. Explore how this works at halliardmedia.com/trytoday.
