Market context
The live issue is how many qualifying main-feed posts, quote posts and reposts Elon Musk publishes on X during the two-day window, with replies excluded unless they appear as tracked main-feed items. For a programmatic approach, the cleanest setup is to monitor the account with a timestamped counter that filters for post type and continuously reconciles deletions, because deleted posts still count if the tracker captures them for long enough.
The current 21% YES price implies the market is leaning towards a relatively low-count outcome versus Musk’s recent bursts, where tracker-style recaps have shown very heavy activity on some days, including 38 posts on 3 August, 44 on 6 August and 95 on 1 August 2026.[8][9][10] That history matters because this market is not about average posting habit but about whether he stays in a high-output mode for this specific 48-hour slice; a quiet weekend can just as easily produce a sub-threshold total, while a single topical flurry can move the count quickly.
The main catalysts to watch are any major Tesla, SpaceX, xAI or X announcements, plus public political interventions or product-launch threads that typically trigger reposting and follow-up commentary on his main feed. The market-specific tracker currently shows zero counted tweets for the window, so traders using automation would be watching for the first qualifying post after 8 August 12:00 PM ET and then updating a live total against the settlement cut-off on 10 August 12:00 PM ET.[2]

The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options.

Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
UK Frequently Asked Questions
