Meta announced the Muse Charm, a palm-sized Tamagotchi-style keychain device running its Muse AI agent with real-time voice, an animated avatar, fingerprint sensor, 2-inch OLED screen, and built-in 5G, at Meta Connect on September 23, 2026. CEO Mark Zuckerberg accelerated the original 2027 target to enable holiday shipping in December, though only a handful of prototypes exist and the team is still finalizing components, materials, pricing, battery life, and full specs. The hardware extends access to the Muse agent—launched September 8 with task-automation capabilities—beyond phones or smart glasses. Traders are watching for any further official updates on production readiness or delays, as Meta has a mixed track record on hardware timelines amid competition from other AI wearables.
