Market context
The FIFA World Cup 2026 Group C clash between Scotland and Brazil, held on 24 June at Miami Stadium, concluded with a decisive 3-0 victory for Brazil, featuring goals from Vinícius Júnior. Despite the high-profile nature of the match and the presence of thousands of spectators, no extraterrestrial abduction occurred during the game, leaving the market’s conditional probability at 0% YES. On Polymarket, this contract is priced using USDC on the Polygon network, where conditional tokens reflect the absolute absence of the specified event, aligning with the on-chain resolution that no player, official, staff member, or spectator was taken by non-human beings.
Historically, markets betting on alien abductions during major sporting events have consistently resolved to “No”, as no credible case of such an event has ever been documented in real-world reporting. From the 1950s to present, every claimed abduction has lacked verification, and no consensus of credible sources has ever confirmed an extraterrestrial intervention during a live match. This pattern frames the current 0% probability not as a speculative guess but as a reflection of empirical reality, where the absence of evidence across decades supports the market’s resolution.
Traders should monitor official FIFA announcements regarding match schedules, venue security protocols, and any unexpected disruptions, though none have materialised for this fixture. Recent coverage from Al Jazeera Sport confirms the match proceeded without anomalies, reinforcing the stability of the “No” outcome[3]. With Brazil securing top spot in Group C and Scotland failing to reach the knockout rounds, the focus remains on footballing outcomes rather than unverified supernatural claims, ensuring the market resolves definitively to “No” based on the consensus of credible reporting.

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.
