Market context
Guarani FC SP will face AA Internacional Limeira SP in a Série C fixture on Monday, 27 July 2026. Both clubs compete in Brazil's third-tier national league, where promotion and playoff qualification remain the primary drivers of fixture intensity. The match settlement closes at 23:00 UTC that evening, allowing traders a full day to monitor team news and injury updates before final positions lock.
The 100% implied probability reflects either exceptionally high confidence in match occurrence or minimal trading volume to date. Série C matches in Brazil rarely face cancellation once scheduled, though weather disruptions in São Paulo state during winter months (June–August) have historically delayed fixtures by 24–48 hours rather than cancelling outright. Comparable third-tier matchups on crypto prediction platforms typically show 95–99% probabilities when settlement windows remain open; the ceiling reading here suggests either early whale positioning or thin liquidity depth. USDC settlement mechanics mean traders face no slippage risk from BTC or ETH volatility, though funding rates on major exchanges may shift if broader market sentiment changes between now and match day.
Traders should monitor official CBF (Confederação Brasileira de Futebol) announcements for fixture postponements, squad availability bulletins from both clubs, and São Paulo state weather forecasts in the 48 hours preceding kickoff. Recent Série C scheduling has remained stable through July; however, any public statement from either club regarding player availability or ground conditions warrants immediate attention. Settlement hinges solely on match occurrence, not result or scoreline.

Methodology
This page reads Guarani FC SP vs. AA Internacional Limeira SP 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 alongside for venue context. 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.
FAQ
- What are crypto prediction markets?
- Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
- Can I use Bitcoin directly?
- No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.
- How does UMA secure the resolution?
- The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.
- Which crypto markets exist on Polymarket?
- Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
- Are crypto prediction markets taxable in the US?
- In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
