100-word summary
Amazon is quietly adding AI-generated prompts to your Sponsored Products and Sponsored Brands campaigns, and starting March 25, you'll pay for every click. The feature, which left beta in November, uses product page data to surface contextual prompts automatically. You can pause individual prompts, but they're on by default. The catch: prompt-level costs now flow through your regular cost-per-click bidding, so a chatty AI could drain budgets faster than expected. Amazon provides granular reporting on which prompts drive clicks versus which just burn cash. The shift puts the burden on advertisers to police AI-written ad copy they didn't create.
