Trade Desk (TTD) Q3 2025: Kokai Drives 26% CPA Gains, CTV and International Outpace Core
Trade Desk’s latest quarter marks a decisive pivot toward AI-fueled performance and global expansion as Kokai adoption and CTV channel growth reshape the revenue mix. Leadership’s structural overhaul and product innovation cadence are moving the business beyond legacy digital ad models, with international and vertical diversification emerging as new growth engines. Management’s outlook signals confidence in capturing open internet share as walled gardens retrench, but execution discipline and macro headwinds remain critical watchpoints.
Summary
- AI Platform Upgrade Transforms Performance: Kokai adoption is delivering double-digit efficiency gains across key ad metrics.
- CTV and International Channels Accelerate: Video and non-US markets outpace core, diversifying Trade Desk’s growth profile.
- Leadership Reset Targets Operational Rigor: New executive hires and go-to-market discipline aim to scale global client wins.
Performance Analysis
Trade Desk’s Q3 results underscore a business model shift toward premium, data-driven open internet advertising, with CTV (Connected TV, streaming video ad inventory) and international operations outgrowing legacy channels. Video, including CTV, now comprises roughly half of total revenue, while mobile and display lag as single-digit contributors. Audio, though still small at 5%, is highlighted as a future growth lever.
AI-powered platform Kokai has emerged as a core differentiator, with nearly 85% of clients adopting it as their default. This upgrade is driving a 26% improvement in cost per acquisition (CPA), a 58% better cost per unique reach, and a 94% uplift in click-through rates compared to prior platform Solomar. Such efficiency gains are supporting wallet share capture among large global advertisers, even as macro headwinds persist in some verticals.
- CTV Momentum Shifts Channel Mix: CTV and video’s share of revenue is rising, reflecting advertisers’ shift to authenticated, measurable environments.
- International Outpaces North America: EMEA and APAC investments yield faster growth than the US, with international now 13% of revenue.
- Vertical Diversification Gains Traction: Sectors like medical, automotive, and tech show above-average growth, while insurance, financial services, and telco are new client wins.
Cash flow remains robust, with $225 million generated from operations and $155 million in free cash flow. The balance sheet is debt-free, and $310 million was deployed for share repurchases in Q3, offsetting dilution and reducing outstanding shares. Management’s continued focus on operating leverage and disciplined investment supports a durable profitability narrative.

Strategic Positioning
1. AI and Platform Innovation as Core Differentiators
Trade Desk’s Kokai platform leverages distributed AI to optimize every campaign function, from impression valuation to supply path selection. The company’s rapid product cadence—OpenPath, DealDesk, Trading Modes, and Audience Unlimited—positions it as the leading independent buy-side DSP (Demand Side Platform, ad buying software for agencies and brands) as walled gardens double down on owned inventory.
2. Go-to-Market and Leadership Transformation
New executive hires across COO, CFO, and CRO roles signal a commitment to operational discipline and global scale. Structured account planning, tighter cross-regional coordination, and a focus on joint business plans (JBPs, strategic partnerships with top clients) are driving faster growth among large advertisers and improving sales effectiveness.
3. Supply Chain and Auction Integrity
Trade Desk’s investments in supply chain transparency (OpenPath, Open Ads, PubDesk) and open-source auction mechanics address industry pain points around inventory duplication and misrepresentation. These moves aim to elevate premium content and enable advertisers to avoid low-quality, ad-saturated environments, reinforcing the company’s buy-side objectivity.
4. Channel and Geographic Diversification
CTV and audio channels, along with international expansion, are reshaping Trade Desk’s revenue mix. The company is capturing growth where authenticated, measurable media is valued most, while vertical wins in healthcare, tech, and financial services diversify risk and opportunity across the client base.
5. Positioning Against Walled Gardens
Trade Desk is capitalizing on a market shift as Google, Amazon, and Facebook focus on monetizing their own platforms, leaving the open internet as a largely uncontested opportunity for independent DSPs. Management sees this as a multi-year window to deepen relationships with global brands seeking objectivity and measurement transparency.
Key Considerations
Trade Desk’s Q3 marks a pivotal moment as the company leans into AI-driven performance, operational rigor, and international scale. Investors should weigh:
Key Considerations:
- AI-Driven Efficiency: Kokai’s measurable gains in CPA and reach suggest sustained share capture from legacy DSPs and walled gardens.
- CTV and Audio Outperformance: Video’s rising share and audio’s growth trajectory could further insulate Trade Desk from display and mobile commoditization.
- International White Space: Faster growth outside North America, with 60% of TAM beyond US borders, points to a multi-year runway.
- Leadership and Process Overhaul: New C-suite hires and structured go-to-market execution are improving client outcomes and internal accountability.
- Supply Chain and Auction Integrity: OpenPath and open ads initiatives may help Trade Desk win premium inventory and drive ecosystem trust, but require ongoing execution.
Risks
Macro headwinds in consumer and retail verticals, as well as ongoing tariff and inflation pressures, could dampen ad budgets. Execution risk remains as new leadership embeds operational changes and as the company scales internationally. Competitive responses from walled gardens, especially around auction pricing and inventory control, could also impact Trade Desk’s open internet share. Regulatory outcomes, such as the Google antitrust trial, may shift industry dynamics and require adaptation.
Forward Outlook
For Q4, Trade Desk guided to:
- Revenue of at least $840 million
- Adjusted EBITDA of approximately $375 million
For full-year 2025, management maintained a stance of disciplined investment and operating leverage, with continued focus on:
- Capturing open internet share as walled gardens retrench
- Scaling international and CTV channel growth
Leadership emphasized that Q4 guidance ex-political implies roughly 18.5% YoY growth, with strong trends in CTV, retail media, and international offsetting softer pockets in some legacy verticals.
Takeaways
Trade Desk’s Q3 highlights a business in transition, with AI-powered product innovation and operational discipline driving measurable client outcomes and positioning the company for global scale.
- AI and Platform Upgrades: Kokai is delivering significant efficiency gains, supporting client retention and wallet share growth even in a competitive, buyer’s market.
- Channel and Geographic Diversification: CTV, audio, and international are outpacing the core, reducing reliance on legacy display and mobile channels.
- Execution Watchpoints: Leadership turnover and operational overhaul are yielding early results, but require sustained discipline as the company scales across new channels and regions.
Conclusion
Trade Desk’s strategic pivot toward AI, premium channels, and global expansion is yielding tangible performance improvements and setting the stage for long-term share gains in the open internet. The company’s execution on product and operational fronts will be critical as it navigates macro volatility and evolving competitive dynamics.
Industry Read-Through
Trade Desk’s results signal a broader industry shift as advertisers increasingly demand transparency, objectivity, and measurable outcomes outside walled gardens. The rising importance of CTV and authenticated channels is a clear read-through for legacy DSPs and media owners, while supply chain transparency and auction integrity are emerging as competitive battlegrounds. As Google and Amazon focus on owned inventory, independent platforms with advanced AI and global reach are well-positioned to capture the next wave of programmatic ad spend. Other ad tech players must accelerate innovation and operational discipline or risk ceding ground in a rapidly evolving digital landscape.
