Market outcomes
| Draw (BK Hacken vs. Hammarby IF) | 26% YES | 75% NO |
| BK Hacken | 31% YES | 70% NO |
| Hammarby IF | 45% YES | 56% NO |
BK Hacken will travel to face Hammarby IF in an Allsvenskan fixture on Sunday, 31 May 2026. The current order book on Polymarket prices a Hacken victory at 26% implied probability, reflecting the away side's underdog status in Swedish football's top division. Settlement occurs at the final whistle.
Historically, Hacken's away record in Allsvenskan has been modest relative to Hammarby's home strength. Over recent seasons, Hammarby has maintained one of the league's stronger home conversion rates, winning roughly 50–55% of matches at Tele2 Arena. Hacken, whilst competitive, has typically struggled to replicate their home form on the road. The 26% probability aligns with typical away-side pricing in Allsvenskan when facing a side of Hammarby's calibre at home, though this varies considerably based on squad form and injury status entering the fixture.
Traders should monitor team news through May, particularly regarding injuries to key attacking or defensive personnel. Hammarby's fixture congestion in late May—including potential cup or European commitments—could affect squad rotation and fatigue levels. Similarly, Hacken's form trajectory in the weeks preceding 31 May will be material; a strong run-in could shift the probability upwards. Weather conditions on match day, whilst rarely decisive, may favour one side's playing style. Official Allsvenskan fixture confirmations and any managerial changes at either club should be tracked through Swedish football media outlets and the league's official channels.

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.
