AI is also becoming foundational in almost every area of our business, from agentic buying, to creative development, to inventory curation, to workflow. It is powering greater productivity throughout our ecosystem and company. We are starting to see some improvements in key areas of DV+, namely mobile app and commerce media partners. We also remain ready in our DV+ business, as it relates to pending remedies related to the Google trial.” said Michael G. Barrett, CEO of Magnite.
