Warner Bros. Discovery rebuilds its ad stack on AWS agentic AI
Warner Bros. Discovery is tearing down the wall between linear TV and digital advertising. The company announced it is rebuilding its entire U.S. ad tech stack on AWS using agentic AI, moving from separate internal workflows into a single automated platform.
What Is Changing
WBD’s new platform puts autonomous AI agents in charge of planning, forecasting, optimization, and measurement across both linear and digital inventory. The agents continuously learn from campaign outcomes and adjust in real time. Advertisers get a unified buying experience instead of negotiating two separate systems.
The platform also opens the door to new ad formats, including interactive ads, and promises more targeted delivery for viewers.
The AWS Stack Under the Hood
The technical build relies on several AWS services working together:
- Amazon Bedrock AgentCore: builds, connects, and runs the AI agents at scale
- Amazon Bedrock: hosts the foundation models in WBD’s closed instance
- Amazon SageMaker: trains custom ML models under WBD’s own data protection and security controls
- Amazon S3: stores data in Apache Iceberg format for the underlying data lake
- Amazon ECS: handles application hosting
- Amazon Q: a natural language interface that lets WBD’s ad sales teams query data, surface insights, and get proactive recommendations without writing queries
Rollout Timeline
WBD started deploying the first wave of capabilities in 2026, covering agentic automation for direct response and commercial workflows, audience forecasting, and measurement. The schedule from here:
- Q3 2026: unified media planning goes live
- Q4 2026: phased rollout of composable order management, pricing, and stewardship
The Operator Angle
For anyone running advertising budgets against WBD inventory (Max, CNN, TNT, Discovery, and the rest), this signals a shift in how you will buy. A unified platform with AI-driven allocation recommendations changes where the leverage sits in negotiations and campaign planning. Watch how the Q4 composable pricing layer lands before drawing conclusions, but the direction is clear: manual ad ops at WBD is being automated away.
