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

Platform comparison

Market context

Elon Musk’s post volume on X between 11 and 18 August will be counted from his main feed, including reposts and quote posts, with replies on the main feed also included under the tracker’s rules. The current crowd-implied 0% YES is a strong signal that the market is not pricing any single bracket as a live candidate yet, but for a counting market the more useful lens is historical cadence rather than the headline probability: Musk’s posting behaviour is highly bursty, so the same account can move from quiet stretches to very high-volume days without warning.[1][6][10]

For a power-user running this programmatically, the key inputs are not sentiment but throughput: monitor the account feed, apply the tracker’s inclusion rules, and reconcile the live tally against the market’s bracket structure as the window opens. Recent market snapshots on the same August sequence have shown heavy activity and wide distributions across adjacent bins, with one venue reporting the 180-199 bracket leading on the prior week’s market and another noting substantial volume around the same event family.[6][11] That makes catalysts more operational than thematic: product launches, Tesla or SpaceX announcements, policy commentary, or litigation and DOGE-related headlines can all trigger posting spikes, and a 7 August report on DOGE’s overstated savings shows how quickly a fresh news cycle can feed into Musk’s posting cadence.[15]

The practical approach is to treat this like a live counter rather than a narrative bet: ingest every qualifying post, exclude replies off the main feed, and watch for deletions that remain live long enough to be captured, since the settlement rules count those as well. If he enters the window with an active news cycle or an announcement rhythm, the market can reprice rapidly as the running total approaches adjacent brackets, so conditional orders and automated refreshes matter more than static pre-window positioning.[1][16]
