Connected TV Advertising Statistics

CTV spending is accelerating while traditional TV declines, forcing CMOs to master programmatic video buying and audience targeting at scale.

Last updated: February 2026 · By AI-Ready CMO Editorial Team

Connected TV (CTV) advertising has become the fastest-growing channel in digital marketing, driven by cord-cutting, streaming adoption, and sophisticated audience data. Over 80% of U.S. households now use streaming services, fundamentally reshaping how brands reach consumers. Unlike traditional broadcast TV, CTV enables real-time bidding, granular audience targeting, and measurable ROI—capabilities that appeal directly to data-driven CMOs building business cases for board approval.

However, CTV adoption among marketers remains uneven. Vendor-sponsored research from streaming platforms and ad tech firms often inflates opportunity size, while independent studies from Gartner and Forrester reveal execution challenges: fragmented inventory, measurement complexity, and rising CPMs. The data tells a clear story: CTV is no longer optional, but mastering it requires investment in new tools, talent, and measurement frameworks.

This collection synthesizes credible research to help CMOs understand CTV's role in 2025 media strategy, identify realistic ROI expectations, and build confident business cases for stakeholder buy-in.

U.S. CTV advertising spending is projected to reach $32.5 billion in 2024, representing 23% year-over-year growth.

This figure reflects the shift of TV budgets from linear to streaming. However, eMarketer's projections assume continued cord-cutting and platform consolidation. The growth rate masks significant variation by vertical: direct-to-consumer and financial services lead adoption, while CPG and automotive lag. CMOs should note that growth doesn't equal profitability—rising CPMs are compressing margins for mid-market advertisers.

Approximately 84% of U.S. households subscribe to at least one streaming service, with the average household subscribing to 4.7 services.

This breadth of penetration makes CTV a near-universal reach channel, but fragmentation creates a buyer's nightmare. Reaching a single audience across Netflix, Disney+, Amazon Prime, and Hulu requires multiple buys, each with different targeting capabilities and measurement standards. The 4.7-service average suggests audience fatigue and subscription churn, which impacts campaign frequency and creative fatigue.

CTV advertising viewability rates average 65-70%, compared to 50-55% for display and 45% for standard video.

Higher viewability is a genuine CTV advantage, driven by full-screen viewing and lower ad load. However, this metric masks quality variance: viewability on premium platforms (Netflix, Disney+) exceeds 75%, while ad-supported tiers and AVOD services drop to 55-60%. CMOs should negotiate viewability guarantees in contracts and avoid conflating viewability with engagement or conversion.

Programmatic CTV buying accounts for 72% of all CTV ad spend, up from 58% in 2022.

Programmatic adoption accelerates efficiency and scale, but introduces new risks. Programmatic CTV relies on third-party data and audience segments that vary widely in accuracy. Vendor-sponsored research from ad tech platforms inflates the benefits of programmatic; independent audits reveal 15-25% audience overlap and segment drift. CMOs must invest in first-party data strategies and audience validation to avoid wasted spend.

The average CTV CPM in 2024 ranges from $25-$50 depending on audience quality and daypart, with premium inventory exceeding $75 CPM.

CTV CPMs have risen 35-40% since 2021, driven by demand concentration and limited premium inventory. Prices vary dramatically by platform, audience segment, and time of day. Vendor reports often cite lower averages ($20-$30) by bundling low-quality remnant inventory. CMOs should benchmark against category peers and negotiate volume discounts; expect 20-30% premium for first-party audience data and brand-safe environments.

Only 42% of CMOs report having adequate measurement and attribution capabilities for CTV campaigns.

This is the critical gap limiting CTV ROI confidence. Most CTV platforms offer last-click attribution, which overstates CTV's impact on direct conversion and undervalues its role in awareness and consideration. Cross-device tracking remains fragmented; only 35% of CMOs can reliably attribute CTV exposure to web or mobile conversion. This measurement gap is the primary reason CTV budgets remain small relative to search and social, despite strong reach metrics.

Brands using first-party audience data for CTV targeting report 2.5x higher conversion rates than those relying on third-party segments.

This is vendor-sponsored research, so apply skepticism—Salesforce benefits from higher CTV spend and data integration. However, the underlying insight is sound: first-party data (email lists, customer IDs, website visitors) significantly outperforms third-party audience segments. The 2.5x lift assumes proper list matching and frequency capping. CMOs should prioritize CRM integration and authenticated audience strategies over broad demographic targeting.

CTV ad fraud rates are estimated at 8-12% of impressions, with sophisticated bot traffic and domain spoofing as primary vectors.

CTV fraud is lower than display (15-20%) but higher than many CMOs expect. Fraud concentrates in programmatic buys and low-cost inventory. Premium, direct deals with major platforms (Netflix, Disney+) have near-zero fraud. CMOs should require fraud detection guarantees in programmatic contracts and audit trafficking partners quarterly. Budget 10-15% waste allocation for fraud, bot traffic, and viewability failures.

Analysis

Key Patterns

CTV is experiencing explosive growth in spend and adoption, but this masks three structural challenges. First, fragmentation is accelerating: the average household subscribes to 4.7 services, forcing CMOs to execute multiple buys with inconsistent targeting and measurement. Second, costs are rising faster than efficiency gains: CPMs have doubled since 2021, while measurement gaps prevent confident ROI attribution. Third, first-party data is becoming the primary differentiator: brands with integrated CRM and audience strategies achieve 2.5x higher conversion rates than those relying on third-party segments.

What This Means for CMOs

CTV is no longer a growth channel—it's a necessity for reach. With 84% household penetration and 72% programmatic adoption, CTV has become the default video environment for many audiences. However, the path to profitability requires three investments: (1) first-party data infrastructure and CRM integration, (2) measurement and attribution technology to close the 58% gap in CMOs lacking adequate tracking, and (3) negotiation discipline to manage CPM inflation.

The data also reveals a maturity gap: vendor-sponsored research inflates opportunity size, while independent studies expose execution friction. CMOs should expect 15-25% audience overlap in programmatic buys, 8-12% fraud rates, and 35-40% CPM premiums for quality inventory. Building a credible business case requires conservative assumptions: assume 2-3x longer sales cycles than search, 15-20% waste allocation, and 6-12 month payback periods for measurement infrastructure.

Action Items

  • Audit your first-party data readiness: Map CRM data to streaming platforms and test audience matching before scaling programmatic spend. Prioritize email list activation and authenticated ID strategies over third-party segments.
  • Establish measurement baselines: Implement cross-device attribution and incrementality testing to isolate CTV's true impact on conversion. Negotiate platform-level reporting guarantees in contracts.
  • Negotiate volume and quality: Benchmark CPMs against category peers, demand fraud detection guarantees, and structure deals with 20-30% volume discounts. Prioritize direct deals with premium platforms over programmatic remnant.
  • Build internal capability: Hire or train a dedicated CTV specialist. CTV buying requires different skills than search or social; most in-house teams lack programmatic video expertise.
  • Plan for 2-3 year ROI horizons: CTV drives awareness and consideration before conversion. Structure business cases with blended metrics (reach, frequency, brand lift) rather than last-click attribution alone.
