Microsoft taps Amazon DSP as preferred partner

Microsoft is officially winding down its DSP, Microsoft Invest, and naming Amazon DSP as its preferred transition partner – a move that deepens ties between the two tech giants and reshapes Microsoft’s advertising strategy.

Starting Feb. 28, 2026, Microsoft will sunset Microsoft Invest as it shifts focus to its core advertising products: Microsoft Advertising Platform, Monetize, and Curate. The company says the partnership with Amazon DSP will ensure advertisers experience a smooth transition and continue achieving performance goals.

Why we care. Microsoft’s move to sunset its DSP and align with Amazon DSP means advertisers who use Microsoft Invest, will need to migrate campaigns, data, and workflows – but in return, they’ll gain access to Amazon’s powerful audience insights, premium inventory, and stronger performance capabilities across both Amazon and Microsoft ecosystems.

The details. Microsoft Monetize will also join Amazon Ads’ Certified Supply Exchange program, enabling Amazon DSP advertisers to access premium Microsoft inventory and curated deals that combine Amazon shopping insights with Monetize’s supply. Publishers using Microsoft Monetize gain expanded access to high-quality demand and improved monetization efficiency.

What they’re saying. Microsoft emphasized its commitment to supporting customers through the transition, calling Amazon DSP a “natural fit” for advertisers seeking scale, performance, and transparency.

Bottom line. As Microsoft pivots toward conversational and AI-driven advertising, this collaboration offers advertisers a seamless bridge between the two platforms.
