Magnite says CTV publishers are shifting to supply-first pricing

For CTV publishers, the immediate change is more control over how ad inventory is priced and managed. Magnite frames mediation, clearer metadata, unified decisioning, and segmentation as the tools enabling that shift from defensive yield management to supply-first execution. In the broader streaming ad stack, this points to publishers taking a more deliberate role in monetization rather than relying on reactive optimization. The key signal to watch is how often publishers adopt these mediation and segmentation workflows across their CTV inventory.
