Trade: BK Hacken vs. Hammarby IF - Exact Score

Market context

BK Hacken and Hammarby IF will contest a Swedish Allsvenskan fixture on 31 May 2026, with settlement determined by the final score at 90 minutes plus stoppage time. The current 0% implied probability on Polymarket's order book reflects the market's assessment that no single exact-score outcome commands sufficient backing to trade above the minimum threshold. This positioning is typical for exact-score markets in football, where probability mass distributes across dozens of possible outcomes, each individually unlikely. The settlement window closes at 12:00 UTC on match day, allowing traders approximately six hours post-kickoff to finalise positions.

Historical precedent suggests exact-score markets in Allsvenskan fixtures rarely concentrate probability on any single result before team news crystallises. Hacken and Hammarby are mid-table competitors with inconsistent goal-scoring patterns; neither club has demonstrated the attacking dominance that would skew probability towards high-scoring lines. Recent seasons show both sides typically produce 1–1 or 1–0 outcomes in direct matchups, though these remain minority probabilities within the full distribution.

Traders should monitor squad availability in the fortnight preceding the match, particularly injury announcements affecting key attacking players. Fixture congestion in late May—with European qualification implications potentially still live—may influence team selection and tactical approach. Weather conditions at the Bravida Arena in Gothenburg, where Hacken plays, occasionally affect ball movement and scoring patterns. Any postponement would extend the settlement window until the rescheduled date.

Resolution source

How to trade this market step by step

How active is this market?

$1K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for soccer contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Key terms

YES / NO share

A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

CLOB

Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.

Liquidity

USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.

UMA optimistic oracle

The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.

Slippage

The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.

Conditional token

ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Frequently asked questions

Risk and regulatory note

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
