Meta announced the Muse Charm, a Tamagotchi-style keychain device with a 2-inch OLED screen, fingerprint sensor, 5G modem, and cameras to provide always-on voice access to its Muse AI agent, at Meta Connect on September 23, 2026. Zuckerberg targeted a December holiday launch to capitalize on year-end demand, yet emphasized that components remain unfinalized and no pricing or full specifications have been released. This positions the market around whether Meta can execute on the aggressive timeline amid competition from other AI wearables and agents. Traders are watching for prototype updates, supply-chain signals, or any slippage that could shift implied probabilities before year-end resolution criteria.
