Market context
Silkeborg IF are hosting FC København in the Denmark Superliga, and the current crowd-implied probability of 0% YES is far below what external books show for the match environment. Across comparable pre-match markets, FC København are priced as clear favourites: one odds guide puts them around 1.68 decimal, another around 1.61-1.66, while Silkeborg are generally in the 4.5-5.3 range and the draw near 4.0-4.2.[3][5] On a platform-comparison read, that kind of spot usually reflects how Polymarket-style implied probabilities can diverge from the same fixture on Kalshi, Betfair or Smarkets, where the same event would be expressed as decimal odds or traded prices, then reduced further by commission or fees; the practical result is that a “0%” crowd print can coexist with a live sportsbook favourite if the market definition is narrower than the match result itself.[1][3][10]
The key catalysts are team news, market specification, and whether the relevant “more markets” settlement rule tracks the full match or a named sub-event, because that determines whether pre-match odds movement matters at all. ESPN’s market page shows several goal and team totals priced around the fixture, including BTTS Yes at -180 and FC København team totals heavily shaded to the over, which suggests traders will watch line-ups and late injuries for any drift in scoring expectation before kick-off.[2] Recent preview pieces also note correct-score and BTTS angles, with odds updates published as recently as 31 July, so any late squad announcement or schedule change could reprice adjacent contracts even if the headline 1X2 view stays stable.[8]
Methodology
This page compares Silkeborg IF vs. FC København - More Markets specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. The live probability is the Polymarket mid; the comparison columns summarise each venue's fee structure, KYC, settlement currency and payment rails. Every CTA routes to Robinhood Prediction Markets, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
FAQ
- What does Polymarket cost vs Kalshi?
- Polymarket: 0% fees, only Polygon network costs (~$0.01/trade). Kalshi: up to 7% per trade plus spread. For high-frequency traders, Polymarket is dramatically cheaper.
- Is Betfair a Polymarket alternative?
- Only partially. Betfair Exchange is UK-focused with a sports-betting emphasis; they have politics markets but with thinner liquidity than Polymarket. Settlement in GBP/EUR, 2-5% commission on winnings.
- Which platform is accessible globally?
- Polymarket is geo-blocked in the US/UK/EU. Kalshi is US-only. Betfair and Smarkets are UK-restricted. Robinhood Prediction Markets has a different geo footprint and routes to Polymarket's order book at 0% fees.
- Are all these platforms regulated?
- No. Kalshi is CFTC-regulated (US). Betfair and Smarkets are UK Gambling Commission licensed. Polymarket operates without explicit regulation — a different risk profile than a regulated sportsbook.
- Which platform supports Klarna/SOFORT?
- Directly: none. Polymarket accepts only USDC on Polygon. Robinhood Prediction Markets offers a fiat on-ramp via Klarna or SOFORT (DE/AT/CH) and converts internally to USDC for the Polymarket order book. T+1 processing.
