Meta announced the Muse Charm, a keychain-sized hardware device for its Muse personal AI agent, at the September 23, 2026 Connect event, accelerating an original 2027 target to meet a December holiday shipping window. The palm-sized gadget features a roughly 2-inch screen, fingerprint sensor, 5G connectivity, and real-time voice/avatar support to let users interact with the agent without a phone or smart glasses. Muse itself launched just two weeks earlier on September 8 and quickly topped U.S. app charts with millions of downloads. The device remains in early prototype stage with no price, full specs, or confirmed availability details released yet. Traders are watching Meta’s execution on finalizing components, regulatory or supply-chain hurdles, and any updates at upcoming earnings or developer events that could confirm or slip the December timeline.
