What Roku, Disney, Netflix, Spotify, SiriusXM (and more) signal for advertisers in 2026 and beyond
In 2025, Amazon made one thing unmistakably clear: it is no longer content to simply participate in the open web advertising ecosystem. It intends to orchestrate it.
In a span of just months, Amazon announced strategic partnerships with:
- Roku
- Disney Advertising
- Netflix
- SiriusXM
- Spotify
- iHeartMedia
- Microsoft
Individually, these announcements look like distribution deals. Taken together, they represent something much larger: a structural reset of how omnichannel advertising will be planned, bought, and measured going into 2026.
This article breaks down:
- What Amazon is actually building
- What these partnerships mean for advertisers today
- How they work inside Amazon DSP
- What we expect to come next in 2026
Amazon’s Endgame: One Planning Layer for Premium Media
For years, advertisers have accepted fragmentation as the cost of omnichannel reach. Separate buys for CTV, streaming audio, podcasts, and open web video. Disjointed frequency. Inconsistent measurement. Endless reconciliation.
Amazon’s 2025 partnerships point to a different future. Across every announcement, the same pillars appear:
- Single entry point through Amazon DSP
- Logged-in reach for deduplication and frequency control
- Clean-room data collaboration for full-funnel measurement
- Commerce, streaming, and browsing signals unified
- Premium, brand-safe environments at global scale
Amazon is positioning Amazon DSP not as a retail extension, but as the control plane for premium digital media.
The Partnerships, Explained
Roku: The Largest Authenticated CTV Footprint in the U.S.
The Roku partnership gives Amazon DSP exclusive access to the largest authenticated CTV footprint in the U.S., reaching an estimated 80 million households.
What this unlocks:
- Deterministic identity across Roku OS and Fire TV
- Higher unique reach with fewer wasted impressions
- True frequency control across streaming environments
- CTV that behaves like a performance channel, not just awareness
Early results showed advertisers reached ~40% more unique viewers with nearly 30% lower frequency, a meaningful shift for CTV efficiency.
Disney Advertising: Premium Content Meets Commerce Intelligence
Through a direct integration between Disney’s Real-Time Ad Exchange and Amazon DSP, advertisers gain access to Disney+, Hulu, and ESPN inventory with enhanced transparency.
Key differentiators:
- Contextual targeting via Disney Magic Words
- Future data matching between Disney audience data and Amazon commerce signals
- Activation and measurement through clean-room collaboration
This is not just access to premium inventory; it’s intent-driven planning inside premium content.
Netflix: Global Streaming TV, Planned Once
Netflix’s integration allows advertisers to access Netflix’s ad-supported inventory across multiple global markets directly through Amazon DSP.
Why this matters:
- One buy, many countries
- Consistent reach and frequency across borders
- Unified measurement tied back to business outcomes
For global brands, this removes one of the biggest barriers to scaling streaming TV internationally.
Spotify, SiriusXM, and iHeartMedia: Audio Becomes a Full-Funnel Channel
Amazon’s audio strategy matured rapidly in 2025.
- Spotify brings global streaming audio and video into Amazon DSP
- SiriusXM adds Pandora, SoundCloud, and soon podcasts
- iHeartMedia expands access to streaming audio now, with broadcast radio and podcasts coming in 2026
Collectively, this creates:
- Massive logged-in audio reach
- Audio planning tied to shopping and browsing intent
- Measurement that connects exposure to downstream outcomes
Audio is no longer a “nice-to-have.” It is becoming a core performance lever.
Microsoft: Consolidation of the Open Web
Amazon’s designation as the preferred DSP for Microsoft Invest customers, alongside Microsoft Monetize joining Amazon’s Certified Supply Exchange, signals something critical:
The open web is consolidating around fewer, higher-signal buying platforms.
For advertisers, this means:
- Easier migration from legacy DSPs
- Better data alignment
- Cleaner supply paths
- Fewer intermediaries eroding performance
What This Means for Advertisers Today
For advertisers working inside Amazon DSP, the implications are immediate:
- Plan once, activate everywhere
- Control reach and frequency across CTV, audio, and video
- Measure consistently using first-party signals
- Reduce waste caused by overlapping audiences
- Shift CTV and audio from awareness to accountable channels
Media planning is becoming less about channel silos and more about audience orchestration.
Looking Ahead: What We Expect in 2026
Based on the trajectory of these partnerships, several themes are likely to accelerate in 2026:
- More Exclusive Supply Alignments: Expect additional premium publishers to prioritize Amazon DSP as a primary activation layer.
- Expansion of Logged-In Identity: Authenticated reach will extend deeper into international markets and new formats.
- Audio and Podcast Scale: With iHeart and SiriusXM expanding in 2026, podcasts will increasingly behave like programmatic video.
- AMC-Driven Planning Becomes Standard: Audience creation, sequencing, and incrementality measurement will increasingly originate in Amazon Marketing Cloud, not post-campaign reporting.
- Fewer “DSP-of-Record” Decisions: Agencies and brands will consolidate platforms to reduce complexity, favoring DSPs that offer scale, identity, and measurement in one place.
The Bottom Line
Amazon’s 2025 partnerships are not about buying more inventory. They are about owning the orchestration layer of modern media.
For advertisers, this means fewer fragmented buys, better signal alignment, and more confidence that media investment is driving real business outcomes. Media planning is no longer about stitching channels together. It’s about building once and activating everywhere.
