Warner Bros. Discovery launches agentic AI platform to unify ad buying
Warner Bros. Discovery is expanding its ad tech stack on AWS with a new agentic AI-driven platform designed to automate media planning, audience forecasting, and inventory allocation across digital and linear channels. Built on AWS services like Amazon Bedrock and SageMaker, the platform unifies previously siloed buying workflows to offer real-time optimization for advertisers.
Key Takeaways
- Deployment of Amazon Bedrock AgentCore and SageMaker to power autonomous agents for real-time inventory allocation.
- Unified media planning launch scheduled for Q3 2026, followed by automated order management and pricing in Q4.
- Transition to Apache Iceberg data format on Amazon S3 to support a composable interoperability layer for AI context.
- Integration of 'Amazon Quick,' a natural language AI assistant for ad sales teams to query campaign data.
Why It Matters
WBD is addressing the chronic fragmentation between linear and digital television by automating the 'swivel-chair' workflows that traditionally separate the two. By moving beyond rules-based automation to agentic AI, WBD can offer dynamic audience forecasting that adjusts to viewing shifts instantly. This shift places WBD in direct technical competition with Netflix and Disney, both of which are aggressively internalizing their ad tech stacks to capture higher margins. Success here hinges on whether the AI can effectively manage brand safety and frequency capping across massive, diverse content portfolios. Watch for the Q3 unified planning rollout to see if buyer friction decreases for cross-platform upfront deals.
Additional Context
The transition to agentic ad tech follows a period of financial pressure for WBD, which reported a 7% year-over-year decline in advertising revenue to $1.85 billion in Q1 2026, per Marketing Dive. This softness was largely attributed to the ongoing erosion of the linear television market and specific programming gaps, making the technical convergence of digital and linear a strategic necessity rather than an optional upgrade. The rollout also aligns with a broader industry push toward 'agentic' systems; Fox announced its own end-to-end agentic platform in the same week, and the IAB Tech Lab has begun developing open-source Agentic Advertising Management Protocols to standardize how these autonomous systems interact. WBD's pivot also reflects shifting subscriber dynamics across the industry. According to research from Digital i in January 2026, usage of ad-supported tiers increased across all major streamers in 2025, with HBO Max's ad-tier adoption rising from 22% to 28% global share. While this provides a larger digital pool for WBD's new AI agents to optimize, the company remains behind competitors like Disney+ and Netflix, which saw ad-tier usage reach 44% and 40% respectively in the same window. By automating the planning process, WBD aims to simplify the buying experience for its portfolio, which currently requires navigating five or six different internal systems to execute a single cross-platform campaign, according to WBD data-driven ad sales executives.
