Market context
SC Internacional and Clube do Remo are scheduled to meet in Brazil's Série A on 17 August at 7:00 PM ET. The fixture sits within the league's standard matchday calendar, with both clubs competing for points in the domestic top flight. This market signals additional betting opportunities beyond the standard match outcome, likely covering player performance, goal totals, or card counts—the precise settlement criteria remain dependent on platform-specific market definitions published closer to kickoff.
The 0% implied probability reflects either a market that has not yet attracted liquidity or one where traders are awaiting clarification on settlement terms. Historical precedent from similar "More Markets" fixtures in Brazilian football shows these auxiliary markets often remain dormant until 48–72 hours before the match, when team news and injury confirmations crystallise. Comparable Série A matchdays demonstrate that conditional order logic—triggering bets only if specific lineups are confirmed or weather conditions meet thresholds—performs better than static entry strategies on these secondary markets.
Traders monitoring this fixture should track official team announcements regarding squad availability, typically released by clubs on the day before or morning of the match. The settlement window closing at 23:00 UTC on 17 August provides a narrow window for late-breaking information; automated feeds ingesting official league communications or club social channels can flag roster changes that shift market odds materially. Recent Série A matches have shown that even minor positional changes or suspension confirmations can swing secondary market probabilities by 15–25 percentage points within hours of kickoff.

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
UK Frequently Asked Questions
- 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.
- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- Do I pay tax on prediction market profits in the UK?
- UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
