Active sub-markets

Market context

Flamengo and Coritiba will contest a Série A fixture on 30 May at 3:00 PM ET, with settlement tied to USDC on-chain within hours of full-time. The 100% implied probability reflects either extreme confidence in market-making liquidity or minimal trading volume; such crowded odds often signal thin order books rather than genuine certainty. Traders should verify actual depth on btc-prediction.bet before committing capital, as late-window shifts in Brazilian football markets frequently occur when retail interest spikes post-announcement.

Flamengo enters as heavy favourites based on squad depth and recent form, though Coritiba has shown resilience in mid-table contests. Historical Série A secondary markets—particularly those settling on ancillary outcomes like total corners or card counts—have experienced 15–20% probability swings in the final 48 hours as injury reports and team news circulate through local media. The settlement window closes 30 May at 19:00 UTC, allowing roughly four hours post-match for on-chain confirmation; delays in fixture confirmation or VAR decisions have occasionally extended settlement by 24 hours on comparable markets.

Monitor official CBF (Confederação Brasileira de Futebol) announcements for squad changes and fixture rescheduling, which occasionally occur mid-week. Funding rates on correlated BTC/ETH pairs remain stable, suggesting no macro spillover into this contract. Traders should track Flamengo's injury list and any late tactical shifts, as these have historically moved secondary-market probabilities by 5–10 percentage points in the hours before kick-off.

Methodology

This page reads CR Flamengo vs. Coritiba FBC - More Markets on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed for comparison. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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.
