Market context
The Allsvenskan fixture between Kalmar FF and Malmö FF concluded on 20 July 2026 with a 2–2 draw at Guldfågeln Arena, meaning any contract settling on a specific winner or total-goal threshold beyond the draw has already resolved as false. With the crowd-implied probability at 0% YES, the market correctly reflects that the underlying event required for a “YES” settlement did not occur, as the match ended in a tie rather than a decisive result for either side [1][2].
Historically, Allsvenskan matches featuring Malmö FF often see them as favourites, with bookmakers previously assigning odds of 2.54 for a win, yet draws remain a recurrent outcome in tight league contests involving top-tier Swedish sides [3]. Comparable cases from recent seasons show that when pre-match odds favour one team heavily but the game ends in a draw, prediction markets on “winner” or “over/under” contracts typically settle at 0% YES, aligning with the current pricing and confirming the market’s efficiency in pricing in the actual result [4][6].
Traders should monitor the official Allsvenskan settlement logs and on-chain oracle feeds for final confirmation, as USDC-settled contracts on btc-prediction.bet rely on verified match data rather than speculative funding rates or whale flows [1]. With the settlement window closing on 20 July 2026 at 17:00 UTC and the match already finished, no further catalysts such as injury updates or lineup changes will alter the outcome, making this a closed event with definitive resolution [2][6].
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
- 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.
- 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.
- 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.
- 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.
