The new Buffalo Bills stadium, known as the New Highmark Stadium, is expected to officially open for fans in July 2026, although some construction work will continue until December 2026. The stadium will be substantially complete and ready for occupancy by July 2026, allowing the Bills to play all their home games there starting with the 2026 NFL season. The final completion date of construction is currently projected for December 2026, but the stadium will be functional and open for the 2026 football season by mid-year.
