TLDR
Meta launched Muse, a personal AI agent that browses, negotiates and completes purchases on a user's behalf inside a secure virtual machine. No ad product exists yet to place brands inside its logic, and no Australian release date has been set. Three major platforms have now moved to sit between consumers and the buy button within five months.
KEY TAKEAWAYS
What Muse does and how it works
Meta launched Muse on 8 September 2026, describing it as a personal AI agent that acts on a user's behalf rather than simply answering questions. Muse can open a browser, fill out forms, negotiate on behalf of users, send emails, book travel and complete purchases using Link built by Stripe. The product includes purchase protections covering damaged items, price drops, no-fee returns and return guarantees.[1]
The architecture is built around privacy. Muse runs on a dedicated Muse Secure Virtual Machine (VM), a cloud environment that holds both the agent and the user's personal data.[1] A second component, a Sentinel agent, controls what the VM can reach on the internet and requires explicit user permission before any sensitive action proceeds.[1]
Muse is rolling out in the US across iOS, Android and the web at muse.ai, free for most uses with paid subscription tiers for advanced features.[1] Meta said support for AI glasses is coming, with no timeline given. No Australian availability has been confirmed.
What Meta said about ads, and what it did not say
Meta's announcement contained nothing about a commercial product for advertisers. No mechanism has been disclosed by which a brand can pay, bid or otherwise influence which products Muse surfaces, selects or recommends. The decision logic sits inside the VM, and the Sentinel agent controls what enters it.
That gap matters for any retailer whose marketing budget runs through Meta's existing ad products. Those placements reach a person scrolling a feed. Muse intercepts the same person's purchase intent before the scroll ever begins, and no confirmed lever exists for a brand to pull inside it.
Meta has not commented publicly on whether a future ad product for Muse is planned. Prompt the Market could not find an independent source confirming one.
Where this sits against ChatGPT Ads and Amazon's DSP move
The Muse announcement landed inside a five-month window in which three major platforms repositioned themselves at the moment a consumer decides to buy. OpenAI opened a beta self-serve Ads Manager for ChatGPT on 5 May 2026, introducing cost-per-click (CPC) bidding, where an advertiser pays each time a user clicks an ad, along with budget controls and self-serve creative upload for businesses of all sizes.[3]
Two days after Muse launched, on 10 September 2026, Amazon Ads announced a partnership with OpenAI to pipe its demand-side platform (DSP) programmatic technology, software that buys ad inventory automatically across multiple channels, directly into ChatGPT conversations.[2] Select US advertisers are currently testing the pilot.
Chris Conetta, Director of Omnichannel Supply at Amazon DSP, said conversational ads represent the fastest growing engagement opportunity for brands to reach new and existing audiences, with AI-driven ad experiences enabling advertisers to meet relevant users where they spend time today.[2] Katrin Koenig, President of Delta Vacations and one of the first brands in the pilot, said the collaboration lets the company use deep consumer insights to inform how and when Delta Vacations appear within ChatGPT Ads experiences, creating new opportunities for travellers to engage and discover vacation possibilities.[2]
What it means for an Australian retailer running Meta campaigns today
Muse is US-only, the Amazon and ChatGPT pilot is US-only, and the OpenAI Ads Manager has not confirmed Australian availability for any of the three products.[1][2][3] Existing Meta campaigns, keyword buys and feed placements keep running as before.
The structural question is what happens when an AI agent does the choosing: a brand's ability to appear in a Meta feed or bid on a keyword becomes secondary to whether the agent's decision logic ever surfaces it at all. The agent is optimising for the user, not for the advertiser, and shops, compares, negotiates and checks out with the brand either appearing in the result or not. On the ChatGPT side, the Amazon DSP integration gives brands a concrete, if nascent, path: existing Amazon Ads campaigns can extend into conversational placements using the same workflow advertisers already know.[2] Meta has not disclosed a commercial model for Muse as of 10 September 2026.
