If you are new to how CTV buying actually works, this step-by-step guide to advertising on CTV covers the full setup process before you evaluate platforms.
Not all CTV inventory is sold through the same platforms, and choosing the wrong platform for your goals is one of the fastest ways to waste your streaming ad budget. It is also a decision with real stakes: nearly 70% of CTV advertisers plan to increase their spending in 2026 by an average of 17%, driven by the channel’s ability to reach highly engaged audiences and combine television’s branding power with digital precision. Nearly 90% of advertisers say that including CTV in an omnichannel campaign enhances ROI by reinforcing a campaign’s message, but that outcome depends heavily on being on the right platforms for the right reasons.
The options range from self-serve programmatic tools accessible to any business with a few hundred dollars to premium publisher deals that require five-figure monthly commitments. This guide cuts through the noise with a practical comparison of the leading CTV advertising platforms in 2026, who each one is best suited for, and how to decide whether self-serve or managed execution is the smarter path for your business.
How CTV Inventory Is Sold: Two Models to Understand First
Before comparing platforms, it helps to understand the two primary ways CTV advertising inventory is purchased.
Programmatic buying uses automated technology to bid on ad impressions across multiple streaming publishers through a demand-side platform (DSP). You set targeting parameters, a budget, and a CPM range, and the platform finds matching inventory in real time. This approach offers scale, flexibility, and lower entry costs.
Direct publisher deals involve negotiating directly with a streaming platform like Hulu or Roku for guaranteed placements. These come with higher minimum spends but offer premium inventory, priority positioning, and stronger content alignment.
Most businesses start with programmatic and layer in direct placements as campaigns scale and prove ROI.
CTV Advertising Platform Comparison: 2026
| Platform | Best For | Buying Model | Typical CPM | Min. Entry |
|---|---|---|---|---|
| Roku OneView | Broad U.S. household reach | Programmatic / DSP | $15–$35 | Low–Mid |
| Hulu / Disney | Premium brand environments | Direct + Programmatic | $30–$50+ | High |
| Amazon DSP | Performance and retail attribution | Programmatic / DSP | $12–$30 | Mid |
| Samsung Ads | ACR-based audience targeting | Programmatic | $15–$30 | Low–Mid |
| YouTube TV / DV360 | Familiar interface, broad video reach | Programmatic | $10–$25 | Low |
| MNTN | SMBs and DTC brands, self-serve | Self-Serve / DSP | $25–$45 | Low |
Platform Reviews
Roku OneView
Roku holds the largest share of open programmatic CTV inventory in the U.S. at 32%, according to February 2026 data from MediaPost. Its OneView DSP gives advertisers access to Roku’s own household-level data, The Roku Channel’s FAST inventory, and programmatic buys across off-Roku publishers. For businesses prioritizing U.S. reach and household targeting, Roku is typically the first platform evaluated. The trade-off is that its data ecosystem is most powerful within the Roku environment and less dominant off-platform.
Hulu / Disney+
Hulu has long been the premium benchmark for CTV advertising, combining a highly engaged subscriber base with scripted content that commands strong viewer attention. Disney is consolidating Hulu into Disney+ in 2026, merging two of the largest ad-supported streaming audiences into a single buying environment. CPMs run higher than most competitors, but brand safety, content quality, and audience demographics — skewing younger and higher income — justify the premium for the right brand. Direct deals carry meaningful minimums, though programmatic access is available through major DSPs.
Amazon DSP (Prime Video and Fire TV)
Amazon’s CTV offering is built on a data advantage no other platform matches. With over 200 million global Prime members and a direct line to purchase behavior, Amazon can connect ad impressions to real product sales in a way Hulu and Roku cannot. CPMs are among the most competitive in premium streaming, typically ranging from $12 to $30. The limitation for smaller businesses is complexity — Amazon DSP is not a beginner-friendly self-serve interface, and it performs best when first-party or retail data is available to activate against.
Samsung Ads
Samsung’s advertising platform leverages ACR (Automatic Content Recognition) data collected from Samsung smart TVs — giving advertisers insight into what households have actually watched, not just inferred interests. This makes it a strong targeting tool for businesses trying to reach viewers of specific content categories or competitive brands. Samsung currently holds approximately 14% of open CTV programmatic share in the U.S., and its footprint makes it a valuable complement to Roku or Amazon-anchored buys.
YouTube TV / Google DV360
YouTube sits in a unique position: it delivers CTV-style inventory through Google’s ecosystem, making it accessible to advertisers already running Google Ads campaigns. DV360 provides access to YouTube’s TV screen inventory alongside broader programmatic CTV supply. CPMs are generally lower than Hulu or Roku, and the interface is familiar to most digital marketers. The audience skews slightly younger and more mobile-native than traditional CTV platforms, which matters depending on campaign goals.
MNTN
MNTN is purpose-built for performance-focused CTV advertising, with a self-serve interface designed for businesses that want campaign control without the technical complexity of a full DSP. It handles programmatic buying, creative serving, and attribution tracking from a single platform. For small- to mid-size businesses and DTC brands seeking a measurable, direct-response approach to streaming TV, MNTN is consistently one of the most accessible entry points. CPMs run slightly higher than open exchange rates, reflecting the premium on simplicity and built-in measurement.
What Is the Best CTV Advertising Platform?
The best CTV advertising platform depends on your budget, goals, and technical resources. Roku OneView leads in U.S. household reach and open programmatic scale. Amazon DSP offers the strongest retail attribution and competitive CPMs. Hulu and Disney+ deliver premium brand-safe environments with highly engaged audiences. Samsung Ads provides ACR-based targeting for content-aware campaigns. YouTube TV via DV360 suits advertisers already in Google’s ecosystem. MNTN is the most accessible self-serve option for small businesses focused on measurable outcomes.
Self-Serve vs. Agency-Managed: Which Approach Fits Your Business?
Self-serve platforms like MNTN and YouTube significantly lower the barrier to entry, and for businesses with clear goals, a tested video asset, and time to monitor campaigns, they are a legitimate starting point.
The picture changes as campaigns grow in complexity. Managing frequency caps across Roku, Amazon, and Hulu simultaneously, deduplicating household reach across platforms, sequencing creative by exposure stage, and tying it all to a unified attribution model — these tasks require platform expertise and dedicated bandwidth that most internal marketing teams do not have.
What we consistently see at Clicta Digital is that businesses running self-managed CTV campaigns often achieve strong video completion numbers but struggle to connect those completions to downstream revenue. The technical setup for view-through attribution, cross-device tracking, and campaign-to-conversion reporting is where self-serve tools have a ceiling.
An agency-managed approach makes the most sense when a business spends $3,000 to $5,000 per month on CTV across multiple platforms, or integrates streaming campaigns into a broader paid media strategy. At that level, the efficiency gains and clarity of attribution from professional management typically exceed the management fee. Clicta Digital’s OTT/CTV advertising service runs campaigns across 200+ streaming channels with full-funnel targeting and attribution reporting built in from day one.
For context on how CTV fits into a broader campaign structure, this guide to full-funnel streaming strategy covers how awareness, consideration, and conversion work together across platforms.
Choose the Right Platform or the Right Partner
The platform landscape in 2026 offers genuine options for businesses at every budget level. Roku dominates reach, Amazon wins on attribution, Hulu commands premium attention, and MNTN makes self-serve execution realistic for smaller teams.
The right starting point is matching your goal and budget to the platform that best serves them, not chasing the biggest name. If that evaluation reveals complexity beyond what an in-house team can manage efficiently, Clicta Digital’s streaming advertising team is worth a conversation.
