SC Internacional vs. CA Mineiro - More Markets

Platform comparison

Market context

SC Internacional’s home Serie A fixture against Atlético Mineiro was scheduled for 22 August at 21:30 UTC at Beira-Rio, with multiple fixtures listings showing the same kick-off and venue. Public previews ahead of the match had Internacional around the lower half of the table and Atlético Mineiro above them, while one market-facing model priced the home side well short of a decisive edge, which fits a low-certainty read on any narrow outcome market.[1][2][3]

For a yes/no “more markets” contract that settles on the game result and related match outcomes, a 0% YES crowd price implies the market was treating the contract as effectively dead or already ruled out before the settlement deadline on 22 August 21:30 UTC. Traders should watch for the final official scoreline, any voiding condition, and whether the underlying match time aligns with the contract’s settlement window; those mechanics matter more than pre-match form once the close is imminent.[1][4] In crypto-linked context, USDC settlement removes fiat rails risk, so any broader BTC or ETH move matters mainly through risk appetite rather than direct linkage; if spot or funding swings are sharp, they tend to affect positioning in the market more than the football result itself.

Methodology

This page reads SC Internacional vs. CA Mineiro - 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 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.

UK Frequently Asked Questions

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

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%.
