Meta announced the Muse Charm keychain device at its September 23 Connect 2026 keynote as a compact 5G-enabled hardware companion for the Muse AI agent, targeting a December holiday ship date with features including a 2-inch touchscreen, dual cameras, fingerprint sensor, and real-time voice interaction. Traders see moderate odds around 60% for an end-of-year release due to the aggressive timeline, unresolved pricing and battery details, and Meta's history of hardware delays, even as the company open-sourced a related gadgets toolkit in October to accelerate development. Competitive pressure from other AI agents and lessons from failed predecessors like the Humane AI Pin add uncertainty, while near-term catalysts such as supply-chain updates or pre-order signals ahead of retail deadlines could shift sentiment.
