How Is AI Transforming CTV Marketing in 2026?

AI-powered CTV marketing has become the fastest way to turn streaming screens into profit engines, not just awareness. Leading brands now use AI to tightly align creative, audience, and bidding so that every CTV dollar drives measurable actions like app installs, website conversions, and offline sales, instead of paying for empty impressions.

Why is connected TV (CTV) adoption accelerating in 2026?

Connected TV has officially overtaken traditional cable and linear TV in reach, with CTV ad spend projected to hit $38 billion in 2026, up 14% year‑on‑year. In the U.S., nearly 90% of households now have at least one connected device, and viewership on streaming platforms has surged past legacy TV for the first time. This shift is not just about reach — CTV delivers 98% ad completion rates because ads are mostly unskippable, versus linear TV where viewers fast‑forward through commercials.

Advertisers are responding by shifting budgets: over 80% now plan to increase their CTV investment this year, and 86% predict they will use generative AI in some form for video ad creation. Yet most still struggle to move from broad brand campaigns to performance‑driven CTV marketing that ties directly to revenue and ROAS.

How are current CTV campaigns still underperforming?

Despite the massive shift to CTV, many brands see rising CPMs and flat or declining ROAS. The core issue is that CTV is still being bought like traditional TV — based on broad dayparts, genres, and 30‑second GRPs — rather than on precise performance KPIs. This leads to wasted spend on impressions that don’t convert, while competitors with AI‑driven, action‑based models capture more share at better margins.

Mediocre targeting is another major leak. Many campaigns still rely on basic demographic or contextual signals (e.g., sports content, female 25–54), resulting in broad reach but low relevance. Without granular, intent‑based segments, CTV audiences often don’t match the actual buyer profile, leading to high cost per acquisition and low incremental lift.

Creative is also a bottleneck. Manually producing 10–15 variations of each 15–30s video for A/B testing is slow, expensive, and rarely covers all audience contexts. As a result, most brands run the same 2–3 creative versions across all placements, missing opportunities to personalize messaging by time of day, device, or user behavior.

What data reveals the performance gap in CTV?

Industry reports show that only about 35% of CTV campaigns today are set up with true performance KPIs (e.g., CPA, ROAS, app installs) rather than impressions and reach. For the rest, success is measured by how many households were reached, not by how many became customers.

Across performance‑focused categories like e‑commerce, gaming, and DTC apps, top performers achieve 3–5× better ROAS than the average. However, those results are concentrated among brands that combine AI‑driven audience modeling, dynamic creative, and real‑time bid optimization — capabilities that are still out of reach for most mid‑sized and growth‑stage companies.

Programmatic CTV adoption is strong, with over half of media buyers expecting to increase their programmatic budgets this year, but many still lack clean, first‑party data and attribution paths. Without reliable measurement, AI automation can’t improve performance; instead, it just scales existing inefficiencies.

Where are the biggest pain points for marketers?

First, there’s a major operational gap: CTV planning, creative, and optimization are still siloed. Teams spend weeks aligning strategy, then days producing assets, and then under‑optimize because they lack unified data or automated rules. This slows time‑to‑market and makes it hard to test rapidly.

Second, measurement remains fragmented. While CTV platforms report impressions and completion rates, few clearly tie exposures to downstream actions like website visits, purchases, or app installs. Without a single source of truth, it’s difficult to compare CTV ROAS to other channels like social or search.

Third, scaling high‑performing creatives is prohibitively expensive at scale. High‑quality video production is resource‑intensive, and manually localizing or personalizing ads for different regions, devices, and audience segments is simply not feasible for most teams.

Fourth, rising CPMs and increased competition make it harder to maintain margins. Brands that rely on broad‑targeting, manual bid management often see CPA creep up over time, especially in competitive verticals like insurance, SaaS, and U.S. / EU DTC.

How do traditional CTV solutions fall short?

Traditional CTV ad buying is built around broad audience packages and CPM pricing, which works for reach and branding but fails for performance. Buyers pay for impressions, regardless of whether those viewers convert, and success is often judged by how many people “saw” the ad, not by how many actually bought.

Most platforms still rely on static audience segments (e.g., “auto intenders,” “streaming viewers”) and manual flighting. Campaigns are planned weeks in advance, and optimization is limited to adjusting frequency, daypart, or budget allocations. This leaves little room to react to real‑time performance signals or experiment with new creatives.

Creative production is similarly manual. Brands typically work with agencies to produce 3–5 video variants, then run them in A/B tests for days or weeks. Changing creatives requires internal approvals, new files, and re‑traffic, delaying optimization and often missing short‑term opportunities.

Manual optimization also limits testing capacity. Teams rarely test more than a handful of combinations (audience × creative × placement), so they miss high‑value micro‑segments and contextual triggers. This results in a long tail of underperforming inventory that continues to drain budget.

There’s also a lack of end‑to‑end accountability. Many platforms operate as “black boxes,” offering limited transparency into how bids are set, which partners are used, and how attribution is calculated. Brands can’t easily verify whether their CTV spend is truly incremental or just duplicating conversions from cheaper channels.

How can AI turn CTV into a performance channel?

AI CTV marketing flips the model: instead of buying impressions, brands buy outcomes like app installs, website conversions, and in‑store sales. AI continuously analyzes audience behavior, content context, creative performance, and conversion data to optimize bidding, targeting, and creative in real time, so every impression is purpose‑driven.

Starti’s platform is built exactly for this shift. It combines AI‑powered audience modeling, dynamic creative optimization (DCO), and real‑time bid automation to run CTV campaigns that are accountable to ROAS, CPA, and LTV, not just impressions. Clients pay only for tangible results, and the technology is optimized to maximize those outcomes at scale.

At the core is SmartReach™ AI, which uses machine learning to predict which households are most likely to convert and dynamically adjusts bids and placements. Starti also integrates OmniTrack attribution, so every CTV impression is tied to measurable downstream actions, giving brands full transparency into incrementality and ROAS.

What are the key capabilities of an AI CTV platform?

An effective AI CTV solution must offer several core capabilities:

• Outcome‑based buying: Shift from CPM to performance pricing (CPA, ROAS, app installs), so budgets are aligned with business goals, not just reach.

• AI audience modeling: Go beyond basic demographics to build look‑alikes of converters using first‑party data, behavioral signals, and predictive scoring.

• Dynamic creative optimization: Automatically generate and serve the best creative variant for each user, based on device, time, context, and prior behavior.

• Real‑time bid optimization: AI adjusts bids by placement, daypart, and audience in real time to maintain or improve ROAS while scaling budget.

• Omni‑channel attribution: Connect CTV exposures to downstream conversions across web, mobile, and offline, so CTV’s true incremental impact is clear.

• Global reach with premium inventory: Access to major streaming platforms and premium content (rather than long‑tail, low‑quality inventory) to ensure quality impressions.

• End‑to‑end transparency: Full visibility into delivered inventory, audience, and spend, so brands can audit and optimize independently.

Starti’s platform delivers all of these capabilities in one integrated stack, designed specifically for performance‑focused CTV marketing at scale.

How does AI CTV compare to traditional approaches?

Brands that switch from traditional CTV to AI CTV typically see 30–80% lower CPA, 2–3× higher ROAS, and significantly faster time‑to‑profitability.

Can CTV campaigns be optimized purely by AI?

Yes, when built on a robust AI CTV platform. Instead of relying on manual rules and weekly reviews, AI can:

• Analyze thousands of combinations of audience, device, content, and creative in real time.

• Automatically suppress underperforming placements and amplify winning ones.

• Adjust bids down when ROAS drops and increase them when conversions are cheap.

• Rotate and refine creative variants based on which messages drive the highest conversion lift.

Starti’s SmartReach™ AI continuously learns from each impression and conversion, so the platform improves targeting certainty and ROAS over time. At the same time, over 70% of Starti’s employee compensation is tied to client performance outcomes, aligning incentives around delivering measurable results, not just selling impressions.

This combination of AI automation and performance‑based incentives turns CTV from a cost center into a scalable profit engine.

How to set up an AI CTV marketing campaign?

Here’s a step‑by‑step process that works with platforms like Starti:

1. Define business goals and KPIs

Start by agreeing on the primary objective: app installs, website conversions, sales, or LTV. Set clear KPIs (e.g., CPA ≤ $15, ROAS ≥ 3.0) and timeframes for the campaign.

2. Connect data and attribution

Integrate website, app, and CRM data with the AI CTV platform. Ensure conversion tracking is reliable (e.g., Facebook Pixel, Google Ads, MMP, or offline attribution).

3. Build AI‑driven audiences

Upload first‑party data (e.g., converters, high‑LTV customers) to build look‑alikes. Combine with AI‑generated segments based on intent, device, and behavior to create high‑propensity audiences.

4. Generate and test creatives

Use AI tools (like Starti’s AI Studio) to generate multiple 15–30s video variants from brand assets, landing pages, or product info. Test variations for different messages, CTAs, and formats.

5. Set up AI bidding and rules

Configure the AI to bid for conversions (installs, purchases, etc.) instead of impressions. Set guardrails (daily budget, max CPA, ROAS target) and let the AI optimize in real time.

6. Launch and monitor

Launch the campaign across premium CTV inventory. Monitor performance through a unified dashboard that ties impressions to conversions and ROAS.

7. Optimize and scale

Let the AI refine audiences, creative, and placements over 1–2 weeks. Once stable, scale budget to similar high‑performing segments and expand into new regions or verticals.

What are four real‑world use cases for AI CTV?

Use case 1: E‑commerce brand scaling U.S. sales

Problem: A DTC fashion brand runs broad CTV campaigns but struggles with high CPA and low ROAS on paid channels.

Traditional approach: Buy generic demo packages on major streaming apps, run 3–5 static creatives, and optimize based on reach and view‑through rates.

With AI CTV (Starti): Switch to CPA‑based buying, use SmartReach™ AI to target high‑intent look‑alikes, and deploy 15+ dynamic creatives that vary by product category and seasonality.

Results: CPA reduced by 42%, ROAS increased from 1.8× to 3.5×, and incremental sales from CTV grew 2.8× in 90 days.

Key benefit: CTV became a true performance channel, not just a branding play.

Use case 2: Mobile app acquiring users in competitive markets

Problem: A gaming app faces high CPI in the U.S. and EU, and struggles to make CTV profitable.

Traditional approach: Buy CTV inventory at fixed CPM, air brand‑awareness creatives, and rely on last‑click attribution from mobile networks.

With AI CTV (Starti): Implement app‑install pricing, use AI audience modeling to identify high‑LTV look‑alikes, and run DCO to match creatives to device type and content genre.

Results: CPI dropped 35%, Day 7 retention improved by 18%, and ROAS from CTV rose from 0.9× to 2.4×.

Key benefit: AI‑driven CTV became a primary acquisition channel, not a secondary brand layer.

Use case 3: SaaS company driving enterprise trials

Problem: A B2B SaaS brand wants to generate qualified trials but finds CTV too broad and hard to measure.

Traditional approach: Run 30‑second brand films in business content, track only impressions and completion rates.

With AI CTV (Starti): Set up a trial‑sign‑up objective, use AI to target decision‑makers in specific industries/regions, and run multiple creatives that speak to different pain points (cost, security, integration).

Results: Cost per qualified trial decreased by 55%, CTV contribution to pipeline grew by 3.2×, and sales rep time‑to‑close shortened by 9 days on average.

Key benefit: CTV was tied directly to pipeline and revenue, not just brand lift.

Use case 4: Global brand entering new markets

Problem: A global retailer launches in a new region and needs to acquire customers quickly with limited local data.

Traditional approach: Rely on broad demographic buys and generic creatives, then manually adjust based on monthly reports.

With AI CTV (Starti): Use global first‑party data to seed look‑alike models, run AI‑generated creatives localized for language and context, and optimize for website conversions in real time.

Results: CPA was 30% below the internal benchmark, ROAS exceeded 2.0× from day one, and measurement confirmed incrementality against search and social.

Key benefit: AI CTV enabled rapid, scalable entry into new markets with performance accountability from launch.

Why is 2026 the right time to adopt AI CTV marketing?

2026 is the tipping point where CTV shifts from reach‑based branding to performance‑driven acquisition. Viewership is now higher on CTV than on linear TV, and ad spend is growing fast, but the winners will be those who can prove ROI and scale profitably.

AI is no longer a nice‑to‑have; it’s the only way to manage the complexity of 100+ audience segments, dozens of creatives, and thousands of placements efficiently. Manual optimization simply can’t keep up with the speed and scale required.

Platforms that still operate on CPM and static segments are becoming commoditized, while AI CTV platforms deliver measurable, incremental growth. Starti is built for this future: it turns CTV screens into profit engines by aligning every impression with a business outcome, not just awareness.

For brands that want to reduce customer acquisition cost, improve ROAS, and scale across markets with confidence, AI CTV marketing is no longer optional.
