Musk’s established posting rhythm of roughly 20–25 tweets per day in recent weeks anchors the 40-64 bracket as the clear market leader at 56% implied probability for the September 26–28 window. Recent three-day periods have repeatedly settled in the 40–89 range amid steady X activity without major product launches or political flashpoints that typically drive spikes above 30 posts daily. The 21% chance on sub-40 outcomes reflects the possibility of a quieter weekend, while the 20.5% on 65–89 captures modest upside if engagement rises. A Starship launch attempt scheduled for Monday could serve as the main near-term catalyst, though historical patterns suggest any surge would need to be sustained to shift the totals materially higher. Traders are pricing the market on Musk’s baseline cadence rather than event-driven volatility.
