The market resolves on Jun 3, 2026, after the highest temperature in Milan on June 3 has been recorded and verified.

Major weather pattern shifts, updated seasonal forecasts, and atmospheric pressure systems affecting Europe could significantly move odds. Heat waves or cold fronts predicted to reach Milan in early June will drive trading activity.

Broader climate anomalies, ocean temperature patterns, and jet stream positioning also influence expectations. As June 3 approaches, short-term forecasts become more reliable and typically cause sharper price movements as uncertainty narrows.
