Visual decision guide (how to choose)

Best CTV Connected TV Advertising Platforms; This flow shows how to think about picking your CTV path in 2026:

Market context: CTV spend and cord-cutters in 2026

• Global CTV ad spend is about $42B in 2026, projected to rise toward ~$58B by 2028. The U.S. alone accounts for an estimated $33.5B in 2026 (up ~28% YoY).
• Streaming now accounts for the majority of TV time in many markets; roughly 82% of U.S. households use at least one streaming service. Cord-cutters and “cord-nevers” are best reached via CTV, not linear.
• IAB’s digital video forecast shows CTV remains a growth engine, though rates are normalizing from the pandemic surge; Best CTV Connected TV Advertising Platforms; advertisers increasingly demand performance outcomes, not just reach.
• Upfront dynamics are shifting: CTV upfronts are overtaking primetime linear for the first time, and sports/live events command some of the highest CTV CPMs.

Platform 1: Roku Ads

Inventory and scale

• Roku reaches more than 90 million U.S. streaming households, making it a dominant gateway to CTV audiences.
• Inventory includes:
  • In-stream video across apps on the Roku OS.
  • The Roku Channel (ad-supported).
  • Home-screen placements (Marquee, Showrooms), screensavers (Roku City), and interactive units.
• Roku Exchange enables programmatic buying for DSPs, but you can also buy directly via Roku Ads Manager and Roku Curate bundles.

Audience targeting

• First-party data from the Roku platform: content consumption, search within Roku, and streaming behaviors.
• Roku Curate (2026) bundles Roku data with purchase data from partners like Best Buy Ads, Criteo, Fandango, Fetch, Instacart, and Kroger. This enables:
  • Purchase-based audience segments.
  • Closed-loop measurement from impression to purchase.
  • Simplified workflows that count toward upfront commitments.
• Performance targeting: via Roku Pixel and Conversions API (CAPI) advertisers can pass website/app events (visits, sign-ups, purchases) to:
  • Build custom audiences.
  • Optimize delivery toward households likely to convert.

Measurement and outcomes

• Roku Ads Manager supports:
  • Pixel-based tracking for site and app events.
  • Server-side Conversions API (CAPI) for more accurate, cookie-resistant measurement and consolidated insights across touchpoints.
• Third-party outcomes: In 2026, Roku became the first major streamer to adopt iSpot’s Outcomes at Scale, enabling advertisers to use iSpot-attributed outcomes (e.g., site visits, leads) to adjust targeting and creative on Roku. Early tests showed material lifts (e.g., SimpliSafe saw +23% leads, +31% site visits).
• Through Roku Curate, several partners provide closed-loop sales measurement, allowing you to measure and attribute actual in-store and online purchases.

CPM and budgeting

• Roku uses CPM pricing with dynamic auctions; you can set max bid CPMs.
• Self-serve entry: Roku says you can get started with as little as ~$500 in total budget for a first campaign.
• External 2025 cost estimates:
  • CPM range: about $20–$60, varying by targeting, placement, and format.
  • Average benchmark cited: ~$30 CPM.
• Expect 2026 CPMs to be directionally similar, with premium home-screen placements and high-demand content at the high end and standard in-stream video closer to the mid-$20s–$30s.

When Roku is a great fit

• You want self-serve access to TV-scale reach without big upfronts.
• You care about tying CTV to retail/purchase outcomes via Roku Curate (e.g., retail/eComm, CPG, telco).
• Brand campaigns that want outcomes-based measurement and lift studies on top of reach.

Gotchas and watch-outs

• Most of Roku’s data advantage is within its own ecosystem; for cross-publisher frequency, you’ll still want a DSP or a complementary buy.
• Premium placements and tight audience segments will push CPMs higher; keep maximum bids in line with your CPA targets.

Platform 2: Samsung Ads

Inventory and scale

• Samsung TV Plus, Samsung’s free ad-supported streaming TV (FAST) service, has more than 100 million monthly active users globally as of early 2026 and is a central plank of Samsung’s CTV offering.

Audience targeting

• Powered by proprietary Automatic Content Recognition (ACR) at the glass level, delivering deterministic content consumption insights from linear TV, OTT, set-top boxes, and gaming environments.

  • Integration with Amazon Ads brings Amazon’s remote-enabled Interactive Video Ad (IVA) technology to Samsung TV Plus. Viewers can “Add to Cart” (for brands selling on Amazon) or take actions like “Send to Phone” and “Sign Up Today,” moving TV beyond pure reach.
  • The Amazon DSP integration means advertisers can use Amazon Marketing Cloud for robust measurement and insights across the funnel for Samsung TV Plus buys.

CPM and budgeting

• ACR data is powerful but limited to Samsung households; ensure the coverage aligns with your target geography and segment.
• Shoppable features and advanced formats may require creative adaptation and additional technical setup.

Audience targeting

• Identity solutions: The Trade Desk promotes UID2 as an open, cross-channel identifier that improves people-based targeting and measurement as cookies phase out.
• Frequency management: control frequency across networks, channels, and devices to improve efficiency and viewer experience.

• Minimum spend: often in the low five figures per quarter for managed accounts, though some self-serve options exist.

When a DSP is the right core

• You care about identity (UID2) and want consistent measurement across many publishers and walled gardens.
• You’re running performance campaigns that require heavy retargeting, lookalikes, and dynamic creative optimization.

Gotchas and watch-outs

• Inventory quality varies: use supply path optimization, brand-safety filters, and trusted publishers to avoid low-quality impressions.
• Data fees and DSP margin can add ~15–25% on top of media CPMs; factor those into your performance targets.
