Resolution rules: read both before trusting a gap
Kalshi
If Corey Conners wins a golf major championship (including The Masters, PGA Championship, U.S. Open, and The Open Championship) before 2030, then the market resolves to Yes.
Polymarket
This market will resolve according to the team that wins the 2026-27 LALIGA Championship. If at any point it becomes impossible for a listed team to win the 2026-27 LALIGA Championship per the rules of LALIGA (e.g., they are eliminated in the playoffs), the corresponding market will resolve to "No". If the 2026-27 LALIGA season is cancelled, postponed after June 14, 2027, 11:59 PM ET or there is otherwise no winner declared within that timeframe, this market will resolve to "Other". The primary resolution source will be official information from LALIGA; however, a consensus of credible reporting may also be used.
