AdRoll reports 45% drop in prospecting CPMs

AdRoll released its Q3 2026 State of Digital Advertising Report, showing a 45% year-over-year decline in display prospecting CPMs from July 1 to Sept. 8, offering a lower-cost window for holiday marketers before prices typically rise. Display retargeting CPMs fell 29.1% year over year, with a 40.2% drop from Q2. Account-based marketing CPMs increased 4.4% year over year but declined 15.1% from Q2. The report also indicates that despite lower ad prices, consumer spending remains steady, with a 4.5% increase in card spending per household. AdRoll CEO Vibhor Kapoor advises marketers to reallocate budgets based on full-funnel performance. The report includes insights from a study with eTail on retargeting challenges, highlighting that only 13% of retailers successfully bring back over 20% of cart abandoners, and underscores the importance of first-party signals in tailoring messaging.

AdRoll Pilots ChatGPT Ads for Multichannel Reach

AdRoll announced a pilot allowing a select group of AdRoll and AdRoll ABM customers to test advertising placements inside ChatGPT. The pilot aims to help SMB, mid-market and B2B advertisers evaluate how conversational-AI placements complement existing media strategies across the customer journey. Ads are designed to appear below ChatGPT responses when contextually appropriate and — according to OpenAI — do not influence model outputs; OpenAI also keeps conversations private and does not sell user data to advertisers. AdRoll will provide campaign support for participants and said the pilot builds on its multichannel investments, including connected TV, digital out-of-home, and Model Context Protocol (MCP) integrations that connect AdRoll with AI assistants and agentic workflows.
