Meta’s recent launches of the Muse AI agent and Muse Wonder frontier models have driven trader optimism, with strong early user retention and competitive benchmark performance lifting shares toward the $1.9 trillion range. Core advertising revenue continues to expand at 20-28% year-over-year, aided by AI-enhanced targeting, while Zuckerberg’s commitment to $130-145 billion in 2026 capital expenditures underscores infrastructure bets that could unlock new agent-based revenue. The 49.5% probability on the $1.75-2.00 trillion bin and 28.9% on $2.00-2.25 trillion reflect this momentum, tempered by upcoming Q3 earnings on October 21 and analyst concerns over escalating spending that could pressure margins. Traders view the near-term outcome as hinging on whether ad growth and AI traction offset infrastructure costs before month-end.
