Market context
Elon Musk’s posting frequency on X during the mid-July 2026 weekend is the real-world event driving this market, with the crowd currently pricing a 61% chance that his total main feed posts, quote posts, and reposts fall within the settlement criteria between 12:00 PM ET on 11 July and 12:00 PM ET on 13 July. Historical data shows Musk’s output is highly volatile: a recent seven-day window (3–10 July 2026) saw 160–179 posts, while a single day in mid-June (13 June) yielded 22 posts, indicating no stable weekly rhythm [1][3][9]. The 40–64 tweet range—implied at 47.5% on a parallel market—has been the most likely single bucket but remains below consensus, reflecting how weekend compression and unpredictable social habits make any narrow count inherently uncertain [1].
Traders should monitor SpaceX’s upcoming 13th Starship test flight, which will deploy V3 Starlink satellites for the first time and is scheduled next week; Musk typically amplifies such milestones with multiple posts, quote posts, and reposts [5]. Additionally, his recent regret over posts about President Trump suggests heightened sensitivity to political discourse, which could trigger bursts of activity if new controversies emerge [2]. The tracker captures deleted posts if they remain visible for ~5 minutes, so even brief outbursts followed by deletions count, while replies—except main-feed replies like his 2024 post—do not [1]. Settlement closes at 16:00 UTC on 13 July, making the final 24 hours of the window critical for resolving whether his pace stays within the implied range.

FAQ
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
