Market context
The contract tracks Elon Musk's posting activity on X during a seven-day window in late May 2026, counting main feed posts, quote posts, and reposts but excluding replies unless they appear directly on the main feed. The settlement window closes 29 May 2026 at 16:00 ET. The 0% implied probability suggests traders currently assess this outcome as either extremely unlikely or the market lacks sufficient liquidity to establish meaningful odds.
Musk's historical posting frequency provides the essential baseline for calibration. Between 2023 and 2025, his daily X activity ranged considerably—from periods of relative silence spanning 48 hours to bursts exceeding 15 posts daily, often clustered around product announcements, Tesla earnings calls, or geopolitical commentary. Weekly totals have historically fluctuated between 20 and 80 posts depending on external events and his operational focus. The current 0% probability likely reflects either an absence of comparable historical data points for this specific week or insufficient market participation rather than genuine certainty about his behaviour.
Traders should monitor Tesla's Q1 2026 earnings schedule, any scheduled SpaceX launches or Starship updates, and broader market volatility in late May, as these typically correlate with elevated posting activity. Regulatory developments affecting X's operations or major tech industry announcements could also influence his engagement patterns. The absence of sportsbook lines on this contract and the zero implied probability suggest minimal cross-platform comparison data; establishing a position would require independent assessment of Musk's baseline activity levels and any known commitments during that specific week.
Methodology
We track Elon Musk # tweets May 22 - May 29, 2026? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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?
- PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- 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?
- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
