AI and Open Web Anxieties

As AI systems gobble publisher traffic, the open web faces scrutiny over ad extensions, subscription strategies, and the value of advertising outside walled gardens.
Agentic Ads Emergence
Meta’s AI assistant can plan and create campaigns, change targeting and budgets, and remember past campaigns, while TikTok’s AI shopping agent automates purchases directly from brands.
Cross-Platform Measurement Challenges
Deduplication remains a challenge, and the industry wants a true apples-to-apples measuring stick for fragmented media environments and new marketing tactics.
Retail Media Growth

Retail media networks are booming, with McDonald’s and Delta launching their own media networks following giants like Walmart, Amazon, Target, United, PayPal, and The Home Depot.
Paramount’s Acquisition
Paramount’s $110 billion takeover of Warner Bros. Discovery closed, forming Skydance with about $82 billion in debt.
Agentic Advertising Deals
PubX bought media quality company Compliant and announced a $5 million Series A, while OpenAI reportedly talks with BlackRock and UAE investors for a $30 billion round at $1.4 trillion valuation.
Industry Shifts
Demand-side platforms face existential questions as AI agents take over ad buying, while supply-side platforms reassert relevance as inventory curation vehicles.
Brand Safety Tools
DoubleVerify and Integral Ad Science are working with OpenAI to adapt brand safety tools for AI answer engines.
Synthetic Data Debate
Synthetic audiences may inform activations but shouldn’t be counted on for centerpieces of big campaigns, according to industry insiders.
Physical Formats Resurgence
Physical formats like in-person and out-of-home advertising are gaining traction amid declining publisher traffic and user trust.
In-Game and Pre-Theatrical Ads
Places where advertisers can secure guaranteed attention, like in-game ads and pre-theatrical ads, are in high demand.
Personal Agents Mainstream
Meta’s Muse is officially mainstream, with people and even people’s moms using the personal agent.
