Market context
Silkeborg IF host FC København in a Danish Superliga match with the “more markets” contract settling on whether additional listed outcomes appear before the window closes. The crowd price at **0% YES** implies no such extra market has been surfaced yet, so the contract is effectively pricing a blank slate rather than a settled football result. The underlying fixture is scheduled for JYSK Park, with match listings giving a 16:00 UTC kick-off on 2 August. [15][1]
Recent and historical meetings point to a lopsided frame for reading that zero price. FC København beat Silkeborg **7-0** in April 2026, and market previews for the same pairing also cited a **4-0** København away win at JYSK Park and a strong overall head-to-head edge for the capital club. Across wider H2H databases, København have far more wins than Silkeborg, which matters because “more markets” contracts on sports often stay near zero unless the exchange or sportsbook layer adds a defined contract family around a fixture. [5][9][13][16]
The main catalysts are operational rather than tactical: whether the exchange lists additional derivatives before the settlement cut-off, whether the fixture schedule changes, and whether the underlying match is delayed, abandoned, or moved, which would affect what is counted as an available market at expiry. For crypto-linked traders, the broader BTC and ETH backdrop still matters for risk appetite into settlement, especially if USDC liquidity on the venue is being reused across parallel sports and macro books; a sharp move in spot or funding can alter how aggressively participants warehouse short-dated event risk, even when the contract itself is a pure on-chain settlement instrument.
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 — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.
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.
- 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.
- 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 volatile are crypto prediction markets?
- Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.
