LG Opens Home Screen Ad Inventory to Magnite's AI Agent in Three-Year Deal

LG has opened its Home Screen advertising inventory to Magnite's AI agent under a three-year agreement, according to a report by ppc.land.

The deal pairs an entry-point ad placement controlled by a device maker with an agent operated by an advertising technology company. Home Screen inventory appears where users land first after switching on a device, a position that has traditionally been sold directly by the manufacturer or licensed to a small set of partners, and it is now being handled with an agent in the loop.

The agreement fits a wider pattern in which ad tech vendors push AI agents into inventory onboarding, buying decisions and optimization, while device makers look to monetize high-visibility placements more efficiently without building a full advertising stack themselves.

For LG, the Home Screen is a high-value surface an agent can call on repeatedly, and committing to three years suggests the arrangement is being treated as a medium-term structure rather than a short experiment.

The report does not disclose deal value, the exact ad formats involved, or when the integration goes live, so the scale and shape of the partnership remain to be confirmed.

Three things are worth watching: how much decision-making authority the agent actually receives over inventory and buying, whether fill rates and pricing on LG's Home Screen inventory shift as a result, and whether other device makers follow with multi-year agent deals of their own.
