Description
Brisbane Roar FC and Sydney FC will compete in an A-League match on April 2, 2026. This event group captures three mutually exclusive outcomes: a Brisbane Roar victory, a Sydney FC victory, or a draw. All markets measure the result after 90 minutes of regular play plus stoppage time, excluding extra time and penalties.

Divergence Detected
Issue:
Kalshi's three markets collectively cover all possible outcomes (Brisbane win, Sydney win, or draw) and each resolves to Yes for its respective outcome, creating logical contradiction where exactly one market must resolve Yes. Polymarket's three markets are mutually exclusive binary outcomes (Brisbane Yes/No, Sydney Yes/No, Draw Yes/No) with standard resolution logic. The platforms use fundamentally incompatible resolution architectures.Hero Tip:
Do not trade across both platforms assuming they settle identically. Kalshi's structure guarantees exactly one market resolves Yes (the actual match result), while Polymarket's structure allows only one of three markets to resolve Yes based on standard binary logic. If you hold positions on both platforms, verify the actual match outcome will map consistently—it should, but Kalshi's unusual wording creates settlement risk. Prioritize Polymarket for clarity; Kalshi's phrasing is ambiguous and may cause disputes.Critical Divergence Points:
- Kalshi: Outlier: Uses a three-market structure where each market resolves Yes if its specific outcome occurs (Brisbane wins → Market 1 Yes; Tie → Market 2 Yes; Sydney wins → Market 3 Yes). This guarantees exactly one market resolves Yes. The resolution rule states 'If [outcome] wins the Brisbane vs Sydney FC professional Australia A League soccer game... then the market resolves to Yes,' creating a logical architecture where all three markets share identical resolution timing and source but are outcome-dependent.
- Polymarket: Aligned with standard binary market logic: Three separate binary markets (Brisbane Win Yes/No, Sydney Win Yes/No, Draw Yes/No) where each resolves independently based on whether its named outcome occurs. Resolution source is official A-League statistics within 2 hours post-match, or credible consensus if unavailable. Postponement keeps markets open; cancellation with no makeup resolves Draw market to Yes, others to No. All three markets refer to 90 minutes plus stoppage time only.
