Villarreal CF vs. Real Sociedad de Fútbol - More Markets

Critical divergence points:

• Polymarket: Distinct stance: Polymarket structures markets as directional spreads (Real Sociedad -1.5, -2.5; Villarreal -1.5, -2.5), over/under totals (1.5, 2.5, 3.5, 4.5 combined goals), and a both-teams-to-score binary. Each market resolves independently based on its specific threshold. For example, a 2-0 Real Sociedad win resolves YES on Real Sociedad (-1.5) but NO on Real Sociedad (-2.5). Resolution source is 'the official final score published on laliga.com' with a 2-hour fallback to credible reporting.
• Kalshi: Distinct stance: Kalshi combines spread outcomes into a single binary structure: the market resolves YES if either Real Sociedad wins by more than 2.5 goals OR Villarreal wins by more than 2.5 goals OR Real Sociedad wins by more than 1.5 goals OR Villarreal wins by more than 1.5 goals. This means a 2-0 win by either team resolves YES, whereas Polymarket's equivalent markets (-1.5 spreads) would resolve YES only for the winning team. Kalshi does not specify a fallback source or 2-hour window; it references 'the Real Sociedad at Villarreal professional La Liga soccer game originally scheduled for Mar 20, 2026 after 90 minutes plus stoppage time.'
