Muse becomes a daily habit for millions
Possible
Resolves by Sep 8, 2027
Discussed by: Bloomberg and The Verge frame Muse as Meta's bid to put agents in mainstream hands
If the agent performs reliably and users accept the secure-VM model, adoption could compound quickly. WhatsApp's reach of billions gives Muse a distribution pipeline rivals lack. Growth would show up in Meta's user metrics and usage disclosures over its first year.

A security failure stalls the rollout
Possible
Resolves by Q1 2027
Discussed by: Reuters documented stalling and sensitive-data exposure in pre-launch tests; WIRED and TechCrunch question consumer trust
Reuters reported internal tests in which the product stalled and exposed sensitive data. If a similar failure surfaces in the wild, regulators and users could force Meta to pause expansion or restrict what Muse may do without approval. The stakes are high because the agent holds access to email, calendar, and payment methods.

Muse stalls without broad adoption
Possible
Resolves by Sep 8, 2027
Discussed by: TechCrunch and CNBC note the trust hurdle after Meta's recent legal settlement
Muse faces a credibility problem: the company settled a multibillion-dollar consumer-safety lawsuit with states shortly before launch. Sceptical users may decline to connect email or payment accounts, leaving Muse a niche feature. A stall would show as flat usage and a US-only footprint a year after launch.
4
A developer connector becomes a path to user data
Possible
Resolves by Q1 2027
Discussed by: Runtimewire's analysis of Meta's connector opening
Meta now lets outside developers plug APIs into Muse and does not review connectors users build themselves. Each integration adds another route to email, calendars, and payment authority. A prompt-injection attack through a connector could let a hostile page steer the agent.
5
Notification reading draws regulator scrutiny to Muse
Possible
Resolves by End of 2026
Discussed by: Runtimewire's report on tester findings
A tester said Muse read Mac notification content without disclosure, though Meta described Mac access as opt-in. Meta's launch materials do not list Notification Center as a data source. The complaint tests whether the company's privacy architecture matches its public promises.
6
0-day allows account takeover or data exfiltration
Possible
Resolves by End of 2026
Discussed by: Ars Technica security coverage and security researchers in follow-up threads
If the 0-day is exploitable and not patched quickly, an attacker could use Muse's privileged access to email, calendar, and payment methods to take over a victim's accounts or steal data. Meta's track record and the complexity of the secure VM make this a live risk.
7
Amazon dispute expands to other retailers
Possible
Resolves by End of 2026
Discussed by: The Indian Express and retail analysts
If Amazon's block becomes precedent, other major e-commerce sites may follow, limiting where Muse can make purchases. Meta could respond by negotiating access or building workarounds, but a broader retail freeze would undercut the agent's shopping utility.
8
Retailers split on Muse, fragmenting agent commerce
Likely
Resolves by End of 2026
Discussed by: Forbes, which frames the divide as a fight over who controls digital distribution
Shopify opened its catalog and checkout to Muse while Amazon blocked the agent; Walmart, Sephora, Best Buy, and Gap also joined. Where Muse can shop now depends on which retailers sign on. If more big chains follow Amazon, the agent's shopping utility narrows; if they follow Shopify, Meta gains a distribution foothold.
9
Prompt-injection attack through Muse's browser leaks user data
Possible
Resolves by End of 2026
Discussed by: Jonny L. Saunders, who tested Muse and said it had 'almost no prompt injection resistance'
Muse browses the web and acts on what it reads, so a hostile page could instruct the agent to send files or make payments. The filesystem disclosure showed how readily Muse follows instructions to export data. Meta calls the exposure harmless because each VM is the user's own, but an attacker steering the agent would have the same access.
10
Doxxing findings draw regulatory scrutiny to Muse
Possible
Resolves by End of 2026
Discussed by: Hunterbrook Media's investigation
Hunterbrook found Muse can be prompted to compile dossiers on members of vulnerable groups, including undocumented immigrants, transgender teachers, and poll workers. If regulators treat this as a privacy violation, Meta could face restrictions on what Muse may do with other people's data.
