Overview
- The council voted 24–20 with two abstentions to transfer the stadium and more than 28 hectares of public land to the clubs.
- AC Milan and Inter will pay €197 million and plan a privately financed €1.2 billion, 71,500-seat arena designed by Foster + Partners and MANICA.
- Construction is targeted to begin in 2027 with opening in 2031, after which the existing San Siro would be largely demolished.
- The stadium will continue hosting events, including the Milano–Cortina 2026 opening ceremony, as part of a phased plan that preserves select elements and adds a museum, retail, offices, a hotel and green space.
- The measure passed over firm political resistance, with Forza Italia abstaining and Lega and Fratelli d’Italia voting no, and opponents signal possible legal action that could delay the project.
