Upcoming changes to the commonly used set of ad technology partners
Starting on or after April 20, 2026, Authorized Buyers will experiment with an updated set of commonly used ad technology partners. If this experiment is deemed beneficial for publishers, the list will be updated on or after June 5, 2026.
This update will reflect the partners that work most closely with publishers globally, determined by data collected from all programmatic demand sources, as well as meeting our privacy standards. You will be able to find the up-to-date version of the list published at Manage your ad technology partners (ATPs). Publishers can view the controls, the list of current ad technology partners and, once the experiment starts, those who are part of the experiment in their accounts in Privacy & messaging. This can be accessed on the European regulations settings page, in the “Your ad partners" menu. If they want to prevent automatic updates or do not want to participate in the experiment, they can select “Do not automatically include commonly used ad partners”. This will create a custom list pre-filled with their current selections, which they can then modify as needed. If they are using a third-party CMP to collect GDPR consent, their list of ad tech partners is managed through their CMP provider.
