Meta’s stock has traded in the mid-to-high $640s recently after surging over 6% on September 9 following the launch of its Muse personal AI agent, which quickly reached top-three rankings in the U.S. App Store with usage exceeding internal projections. Analyst upgrades, including JPMorgan raising its target to $820 on AI monetization potential beyond advertising, plus a new quarterly dividend, have reinforced positive sentiment and supported the 66.5% market-implied probability for a weekly close in the $640–650 range. The 23% odds on $650–660 reflect momentum from these developments, while lower-probability buckets account for typical weekly volatility around current levels near $650. Upcoming catalysts include further Muse adoption metrics and broader AI infrastructure spending updates.
