Market context
This market tracks how many times Elon Musk posts on X between midday ET on 11 July and midday ET on 13 July 2026, counting main feed posts, quote posts and reposts but excluding replies. In prediction markets, a YES share pays £1 if the event occurs (here, if Musk’s count falls within the market’s defined winning range), while a NO share pays if it does not; both trade at prices reflecting the crowd’s implied probability, currently 65% for YES.
Historical windows show Musk’s posting volume is volatile but consistently high, with recent three-day periods often landing between 40 and 64 posts. A comparable June 2026 market on Polymarket saw the 40–64 range priced at 40–64% consensus before resolving NO, while a July 9–11 window also resolved NO, suggesting weekend compression can push counts outside expected buckets [1][4]. The current 65% YES price implies traders believe Musk will hit the target range, though past outcomes show the market remains genuinely split on whether one person’s habits align with a fixed band [2].
Traders should watch for SpaceX announcements, Starship test-flight updates and any X platform changes that might trigger bursts of activity, as Musk often posts heavily around major company milestones. SpaceX recently confirmed V3 Starlink satellites will debut on the 13th Starship test flight next week, a catalyst likely to generate multiple posts [7]. With settlement at 16:00 UTC on 13 July, the final 24 hours of the window will be decisive, and any sudden silence or unusually active stretch could shift the count outside the winning range before resolution.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.
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.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
