Microsoft has rolled out a "Prepare for the Age of AI Shopping" guide that pushes advertisers to prioritize an AI‑ready Merchant Center feed before creative, leveraging AI‑native ad formats, Copilot Checkout and Brand Agents, with performance measured through Clarity AI Visibility. The move follows data showing AI as the fastest‑growing retail traffic source, up 693% YoY and contributing to roughly $262 billion (20%) of global retail sales.
TikTok’s latest Symphony update doubles AI video length to 30 seconds and expands multimodal references from nine to fifty, giving brands richer, more flexible creative assets for campaign automation.
OpenAI is expanding its ChatGPT ad portfolio with a visual ad format that appears during image generation and a Sponsored Agent experience that lets shoppers converse directly with a brand‑run AI. Early tests report a 15.3% lower cost per acquisition for WeightWatchers versus paid‑search benchmarks, highlighting the format’s efficiency.
Supporting this momentum, Snowflake’s AI Gateway for Advertising connects enterprise data with live campaign signals across Meta and TikTok, allowing human‑approved AI‑driven optimizations, while a Kantar study shows three‑quarters of marketers plan to boost AI‑assistant spend in 2027 despite modest consumer trust.
What to watch next: broader rollouts of OpenAI’s visual ads and measurement integrations, adoption rates of Microsoft’s feed‑first strategy across holiday campaigns, and how TikTok’s extended AI video capabilities influence ad spend allocation. Additionally, the impact of governed AI agents like Snowflake’s on advertiser control and compliance will be a key barometer for the industry’s AI adoption trajectory. [[1, 2]]
