As you will all have heard, the remedies phase of Google's ad tech antitrust trial wrapped this week. 

Amazon is cementing its dominance in digital advertising, expanding beyond e-commerce into the broader ad ecosystem.

Following recent partnerships with Netflix and Spotify, Amazon Ads is now absorbing Microsoft’s advertisers as the tech giant shutters its demand-side platform, Microsoft Invest, by March.

Advertisers across major global regions are being smoothly transitioned—via Amazon reps or its partner network — into the Amazon DSP, now one of the most powerful routes to open-web inventory. More than an onboarding move, this signals a strategic consolidation: Amazon gains preferential access to Microsoft’s ad supply and further integrates its programmatic marketplace.

The pitch to advertisers strengthens—reach, performance data, and competitive pricing bundled together. By tying Microsoft’s Monetize exchange into its DSP, Amazon edges closer to becoming the default infrastructure of online advertising, where shopper data meets scaled open-web buying power.

When publishers have seamless, unified campaign views, advertisers benefit

Publishers still operating in a siloed manner between linear and digital are leaving money on the table. Advertisers expect streamlined, integrated cross-platform audience targeting and unified campaign measurement.
