Elon Musk # tweets August 11 - August 18, 2026?

Platform comparison

Market context

The market is pricing Elon Musk’s posting count on X over 11–18 August as a **0% YES** proposition, which makes the **underdog** case the practical question: whether his output lands in the exact counted window and escapes the tracker’s exclusions. The settlement rules matter here. Only main-feed posts, quote posts and reposts count; replies do not, except for reply-style posts that still appear on the main feed, and deleted posts count if they are captured briefly before removal.[2]

Historically, Musk’s X activity is erratic rather than schedule-driven, so a zero-priced outcome mainly reflects the market’s view that the precise bucket is hard to hit, not that he will go quiet. The broader August 2026 market shows traders already expecting heavy overall activity, with the leading August bucket at 17% and the next at 13% in a fragmented range structure.[3] That points to consensus around high volume, but the exact weeklong count is still a classic long-tail setup where small changes in pace can move the tally materially.

The key catalysts are Musk-specific rather than calendar-based: company announcements, regulatory or product news, political commentary, and any high-visibility X drama that prompts reposts or quote posts. With no confirmed posting schedule, traders should watch for headlines around Tesla, SpaceX and X itself, because those are the kinds of events that tend to spike his main-feed activity.[4][8] The current **favourite** is effectively the field against a precise count, while the value angle sits with traders who expect a bursty week and think the crowd is underestimating how often reposts and quote posts can accumulate inside the counting rules.[1][2]
