On September 17, 2025, Amazon Ads unveiled agentic AI tools for its Creative Studio at the Accelerate Conference in Seattle. These tools allow companies to explore ideas, collaborate, and create ads. Amazon Ads also announced that advertisers running sponsored ad campaigns—including Sponsored Products, Sponsored Display, Sponsored Brands, and Sponsored TV—will receive free access to cleanroom services within its marketing cloud, starting immediately. This service was announced twice in separate news releases. A separate report noted that advertising constitutes a $60 billion annual business for Amazon, representing over 9% of its total revenue. Another report highlighted a common advertiser challenge: defining target audiences effectively, noting that poorly defined audiences can lead to ads reaching the wrong people or no one at all.
