Overview

• City councillors passed the measure 24–20 after roughly 11–12 hours of debate, authorizing the transfer of the stadium and about 28 hectares of adjacent land.
• AC Milan and Inter will replace most of the century‑old venue with a privately owned arena on the site once the new facility is operational.
• Plans call for a 71,500‑seat stadium targeted for 2031 at an estimated €1.2 billion, with architecture by Foster + Partners and MANICA and construction expected to begin in 2027.
• Finalizing the transaction before November 10, 2025 is crucial because a 70‑year heritage protection would otherwise take effect and obstruct demolition.
• San Siro will continue hosting events, including the Milano‑Cortina 2026 opening ceremony, as a narrow, partisan vote and possible legal challenges loom over the redevelopment.
