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

Platform comparison

Market context

Elon Musk’s posting volume on X over 11–18 August will be a simple count of main-feed posts, quote posts and reposts, with replies excluded unless they appear as counted main-feed activity. The tracker currently shows **0 tweets** for the window, which is consistent with the market not yet having opened into the relevant dates, so the crowd-implied probability of **0% YES** on a specific bracket should be read as a function of timing, not as a settled view on his eventual activity.[1][3]

The cleanest historical guide is his own recent cadence: Polymarket’s comparable 4–11 August contract framed Musk as typically posting **25–30 times per day**, or roughly **175–210 posts** across a seven-day span, which is why mid-to-high triple-digit brackets dominated that market rather than the extreme tails.[3] In a cross-platform comparison, that sits well above the present crowd reading here: the Polymarket contract is still effectively unwound at 0% YES, while sportsbook-style pricing on adjacent event markets has tended to be much more concentrated around the middle of the distribution than on any single exact total.[3][9][13]

For traders, the main catalysts are Musk’s own schedule and any major company or policy developments that tend to pull his posting rate higher: Tesla, SpaceX, xAI/Grok, X platform changes, and live news cycles all matter because they can trigger bursts of reposts and quote posts.[3][6] The practical dependency is not just headline volume but whether he stays active for enough of the window to build countable posts before the tracker cutoff; if the tracker misses a deletion, Polymarket notes X can be used as a secondary resolution source.[3]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
