Pinterest Opens Display and Video Inventory to Programmatic Deals via Magnite

Pinterest has launched general availability for Programmatic Deals (PMP and Preferred Deals), selecting Magnite as its primary SSP alongside Google Ad Manager and enabling buying via DV360, Amazon Ads, and Yahoo DSP.

What happened

With 640 million monthly active users and over 80 billion monthly searches, Pinterest has opened its display and video inventory to programmatic Private Marketplace (PMP) and Preferred Deals, with Programmatic Guaranteed currently in testing. Magnite serves as the primary supply-side platform (SSP) in North America, while Google Ad Manager supports LATAM and APAC, allowing agency and brand buyers to transact through Amazon Ads, Google DV360, and Yahoo DSP.

Key questions for investors and operators

When evaluating transactions, technology stacks, or commercial partnerships in this space, we recommend looking closely at three questions:

How are programmatic deal floors calibrated so PMP access adds incremental agency demand without cannibalizing direct self-serve bookings?
Which audience and contextual signals are exposed in the bidstream versus kept exclusive to direct deals?
Why was a hybrid SSP architecture (Magnite + GAM by region) chosen, and how are take-rates structured?
