Updated for 2026 by Adify Digital Marketing
Big changes are happening in the world of programmatic advertising! Microsoft has announced a strategic shift in its Demand-Side Platform (DSP) strategy — and it involves Amazon DSP stepping in as the preferred partner for advertisers migrating off Microsoft’s own DSP, Microsoft Invest.
In this blog, we break down what’s changing, why it matters, and how advertisers should prepare to make the most of this transition. 😊
🔍 What’s Happening?
Microsoft is officially discontinuing its own DSP, known as Microsoft Invest, and has named Amazon DSP as the preferred partner for advertisers who need a new platform. The transition is planned to take place as Microsoft Invest sunsets on February 28, 2026.
This means if you currently use Microsoft Invest for programmatic media buying, you’ll need to migrate your campaigns, audiences, and workflows — and Amazon DSP will be Microsoft’s recommended path forward.
🤝 What Is Amazon DSP?
Before we continue, let’s quickly explain what a DSP is:
A Demand-Side Platform (DSP) lets advertisers buy digital ad inventory automatically from multiple sources in real time, choose audiences, bid on placements, and manage campaigns across display, video, mobile, and more — all in one platform.
Amazon DSP, specifically, uses powerful audience data from Amazon’s ecosystem — including shopping behavior — and allows advertisers to reach users both on and off Amazon.
📊 What the Transition Means for Advertisers
Here’s the big picture:
➤ Microsoft Invest Is Ending
Microsoft is phasing out its own DSP — Microsoft Invest — by February 28, 2026. This reflects a broader shift in strategy toward AI-driven advertising and core Microsoft Advertising products like Microsoft Advertising Platform, Monetize, and Curate.
➤ Amazon DSP Is the Preferred Partner
Rather than building its own replacement DSP, Microsoft chose Amazon DSP as the preferred partner to receive migrating advertisers. Amazon DSP offers:
- Full-funnel advertising options
- Powerful targeting using Amazon’s first-party data
- Third-party inventory beyond Amazon’s owned properties
- Seamless migration support for advertisers making the switch
➤ Microsoft Monetize Joins Amazon’s Supply Exchange
In addition to DSP migration, Microsoft Monetize (a supply-side platform or SSP) is now part of the Amazon Ads Certified Supply Exchange program. This means Amazon DSP advertisers will have access to premium Microsoft inventory along with curated deals using Amazon’s powerful shopping insights.
📈 Why This Matters
This shift is important for several reasons:
🔹 1. Industry Consolidation
This partnership helps streamline programmatic buying, reducing fragmentation and giving advertisers a stronger set of tools and inventory to work with.
Amazon DSP’s inventory now includes premium placements from both Amazon and Microsoft properties — this gives advertisers broader reach and deeper data integration than before.
🔹 2. First-Party Data Advantage
A major strength of Amazon DSP is access to Amazon’s rich first-party shopping data — this helps target audiences with greater precision and relevance.
🔹 3. Better Access to Open Internet Inventory
By integrating Monetize into Amazon’s Certified Supply Exchange, advertisers can now tap into Microsoft’s open internet ad inventory as well — expanding beyond closed ecosystems.
🔹 4. Migration Support & Smoother Transitions
Microsoft and Amazon have emphasized a seamless onboarding experience for advertisers moving from Microsoft Invest to Amazon DSP, with guided support and transition resources.
📌 What Advertisers Should Do Next
If you are currently using (or were planning to use) Microsoft Invest DSP, here’s how to prepare:
🚀 1. Start Planning Your Migration
Export campaign data, audience segments, creative assets, tracking codes, and performance data before the shutdown date.
🚀 2. Learn the Amazon DSP Platform
Amazon DSP works differently from Microsoft Invest. Spend time familiarizing yourself with:
- Audience segmentation
- Reporting dashboards
- Creative placements and inventory options
- Attribution and measurement models
🚀 3. Rebuild or Adjust Campaign Structures
Some targeting options and structures might differ in Amazon DSP — so plan how to replicate your existing campaigns effectively.
🚀 4. Test and Optimize
Before full-scale migration, test a few campaigns on Amazon DSP to understand performance differences, pacing, and reach.
📊 This Is Bigger Than Just a Platform Change
Advertisers should view this transition as part of a larger trend: data convergence and ecosystem partnerships are becoming more important than always having independent tech platforms. Access to premium inventory, strong audience signals, and seamless cross-platform capabilities can be a key differentiator in 2026 and beyond.
