Navigating Microsoft’s DSP Shutdown: How to Keep Your Campaigns Running Smoothly

Microsoft has confirmed plans to shut down Microsoft Invest (formerly Xandr DSP) in early 2026, leaving many marketers, agencies, and advertisers wondering how to avoid campaign disruption.

If you’ve relied on Microsoft Invest to activate audience data and buy media programmatically, now is the perfect time to plan your transition strategy.

At Lotame, we know that reliability and consistency are critical to your business. With nearly two decades of experience in data solutions for digital marketers, we’re ready to help you make this transition seamless.

What’s Happening with Microsoft’s DSP Shutdown?

Microsoft Invest — previously known as Xandr DSP and, before that, AppNexus — has long been a key activation channel for programmatic buyers. But Microsoft recently announced it will wind down its DSP offering by March 2026, focusing instead on first-party assets and new AI-powered buying tools.

While Microsoft Monetize (its SSP) will continue supporting publishers, the programmatic buying functionality will sunset, requiring advertisers to shift their demand-side buying strategies elsewhere.

This upcoming change means brands and agencies need to act now to ensure they can continue targeting and activating audiences without interruption.
