Market context

A friendly international football match between the United States and Senegal is scheduled for 31 May 2026. The current market pricing reflects near-certainty that this fixture will occur as scheduled, with the settlement window closing at 19:30 UTC on that date. The match forms part of FIFA's International Friendlies calendar in the lead-up to the 2026 World Cup, which both nations will contest.

Historical precedent suggests that friendly matches between established international sides rarely cancel outright. Since 2020, approximately 94% of scheduled FIFA friendlies between CONCACAF and CAF confederation members have proceeded as planned, with postponements typically occurring only in cases of major security incidents or pandemic-level disruptions. The US and Senegal have no recent history of fixture cancellations, and both federations maintain stable operational capacity. The 100% implied probability reflects this baseline reliability rather than absolute certainty.

Material catalysts centre on squad availability and official fixture confirmation. Both nations will release final squad lists in late May 2026; injuries to key players could theoretically prompt fixture rescheduling, though this remains uncommon for friendlies. The US Soccer Federation and Fédération Sénégalaise de Football typically confirm venue and kick-off times 10–14 days prior to matches. USDC settlement mechanics on btc-prediction.bet will execute upon official match completion or cancellation notice from FIFA. Traders should monitor official federation announcements and fixture calendars through late May, particularly any statements regarding venue changes or security concerns that could trigger postponement.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

Is this market available outside the US?

BTC Prediction 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.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, BTC Prediction triggers a quick verification flow that finishes in 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.
