Market context
The underlying event is the FIFA World Cup 2026 Group C match between Scotland and Brazil, scheduled for 24 June 2026 at Hard Rock Stadium in Miami Gardens, Florida. This fixture, kicking off at 22:00 local time, features high-profile talent including Brazil’s Vinicius Junior, who already scored early in the game against Scotland’s defence[3]. The market in question assigns a 0% implied probability to the occurrence of an extraterrestrial abduction during the match, a figure that aligns perfectly with the absence of any credible sportsbook line or analyst consensus supporting such an outcome.
Historically, no verified case of alien abduction has ever occurred during a major sporting event, nor has any credible report emerged of non-human beings interfering with human matches in recorded history. Comparable incidents involving unexplained phenomena at stadiums remain confined to folklore or isolated, unverified claims that lack consensus from credible reporting sources. Given this absolute lack of precedent, the 0% probability is not merely a prediction but a reflection of the total absence of evidence supporting the event’s possibility.
Traders should monitor official match reports, post-game statements from FIFA, and live broadcast coverage for any anomalous claims, though none are expected. The resolution source will be a consensus of credible reporting, meaning any abduction claim would require corroboration from multiple authoritative outlets to alter the market outcome[5]. Recent coverage confirms the match schedule and broadcast details on BBC One and BBC iPlayer, with no indication of unusual dependencies or external announcements that could introduce such a scenario[5]. The current odds remain static, reflecting the event’s impossibility under all known real-world conditions.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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.
FAQ
- 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.
- What does it cost to trade on Best Prediction Markets?
- Zero. Best Prediction Markets routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
- 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.
