The platform's AI agent will run your budget. Ask whose goal it is working for.

Short answer: Amazon now has an AI agent that can plan campaigns, adjust budgets and execute optimizations. One accountability advocate asked the right question: will it ever recommend spending less? Keep your own customer data, run a holdout, and judge the result in your numbers, not the platform's. (Digiday, Oct 30, 2026)

TLDR

• Amazon's ads brought in almost $20 billion in Q3, up 12% year on year. (Digiday)
• Amazon Ads Agent can recommend and execute optimizations from plain-language instructions.
• Write your win metric, keep a holdout, and ask in writing what you can see.

What did Amazon launch?

Ronan Shields reported in Digiday on Oct 30 that Amazon's ad business generated almost $20 billion in Q3, up 12%. Its filing says: "We expect year-over-year advertising revenue to grow in the high teens in fourth quarter 2026."

Q3 ad revenue dipped slightly from Q2 ($19.81 billion to $19.64 billion). Digiday notes Prime Day fell in Q2 this year, which complicates the comparison. So don't call it a slowdown.

Amazon Ads Agent pulls sponsored ads, display, video and audio into one buying experience. Advertisers can plan campaigns, generate creative, adjust budgets and analyze performance in plain language. The system can also recommend and execute optimizations.

Amazon's Full-Funnel Campaigns go further. Advertisers set products, creative and budget. Amazon's AI decides how the campaign runs. Amazon claims beta results that beat manual setups. Those figures are Amazon's own beta claims and have not been independently verified, so this piece does not repeat them as results.

What can't advertisers see?

Amit Bhattacharyya of Amazon Ads told Digiday that with Full-Funnel Campaigns, advertisers approve creative but cannot select individual channels or specific audiences. His words: "We are figuring out how to give them more transparency on the audience side."

Alex Brownstein, founder of AHB Advisors, told Digiday transparency on an agent buy "comes in five layers": data, decisions, pricing, delivery and results. "Amazon is open where openness brings it more of the budget and closed where its advantage sits."

Jay Mandel, co-founder of the Marketing Accountability Council, put it plainly: "If spending less with Amazon is better for the advertiser, will its agent recommend that?"

This is the same question for Google AI Max or Meta Advantage+. The seller is grading its own work. (Opinion, Head of Content)

"Every time. The rep's deck says conversions are up; the CRM says the phone didn't ring any more. The platform counts what helps the platform. I trust the client's books."

What does doing nothing cost?

The platform reports its own wins. You renew on its numbers. Nobody ever tells you that spending less would have done as well. (Opinion, Head of Content)

Five things to do before an agent gets the budget

1. Write the result you will judge it on in your own numbers: booked calls, CRM sales, new customers.
2. Keep a holdout. A region, a product line, or a few weeks with the agent off. Brownstein's advice per Digiday: use your own customer data and independent incrementality testing.
3. Ask the rep in writing which of Brownstein's five layers you can see: data, decisions, pricing, delivery, results.
4. Log every automated change you can export. Mandel argued advertisers should be able to audit automated changes and inspect fees and inventory decisions.
5. Set a review date. Compare the agent's report to your own numbers before you renew.

Next step

Who: the agency owner and the media lead on any account using platform automation. What: a one-page agent brief per account with the win metric, the holdout and the five-layer visibility answers. When: before the next budget increase or renewal on that platform. How: the five steps above, signed off by the client.
