Description
This event group covers the halftime result of a Sporting CP vs. Arsenal FC match scheduled for April 7, 2026. Three binary markets on Polymarket ask whether Sporting CP leads, Arsenal leads, or a draw exists at the 45-minute mark, while Kalshi presents a single market that resolves Yes for any of the three outcomes (Sporting win, tie, or Arsenal win).

Divergence Detected
Issue:
Kalshi's market structure is logically incoherent: it resolves Yes for all three mutually exclusive halftime outcomes (Sporting win, draw, Arsenal win), making it impossible to use as a prediction market. Polymarket's three-market structure is coherent and standard.Hero Tip:
Kalshi's market will always resolve Yes and has no predictive utility. Trade only on Polymarket's three separate binary markets (Sporting leading / Arsenal leading / Draw at halftime) for meaningful exposure to halftime outcome uncertainty.Critical Divergence Points:
- Polymarket: Three mutually exclusive binary markets. Each asks a single outcome question (Sporting leading Yes/No, Arsenal leading Yes/No, Draw Yes/No). Resolution source: official governing body statistics within 24 hours, or credible reporting consensus. Postponement keeps market open; cancellation resolves No.
- Kalshi: Single market with three resolution conditions, all mapping to Yes. Resolves Yes if Sporting wins halftime, Yes if tie at halftime, or Yes if Arsenal wins halftime. This guarantees Yes resolution regardless of match outcome, rendering the market non-functional as a prediction instrument.
