Muse from Meta holds the leading 62.5% implied probability because it has maintained the top free spot on the U.S. App Store since mid-September, fueled by strong initial downloads exceeding 2.5 million in its first two weeks and ongoing momentum from Meta’s Connect conference updates. The personal AI agent’s task-handling features, secure virtual machine design, free tier with usage limits, and integrations across WhatsApp, Instagram, and Mac have driven sustained user adoption ahead of rivals. Other outcomes like ChatGPT, Threads, Vinted, and Google Gemini trail at 14–26% amid Muse’s chart dominance, while several reserved slots at 50% reflect uncertainty around potential late surges. With the October 9 resolution just days away, traders are weighting recent sustained performance and Meta’s promotional push most heavily.
