The Conjuring: Last Rites, released theatrically on September 5, 2025, is expected to begin streaming on HBO Max in early 2026, likely between December 2025 and February 2026. The film will first be available for digital rental or purchase around mid-October 2025, aligning with the Halloween season. Warner Bros. typically has a theatrical exclusive window of about 90 to 120 days before moving films to HBO Max, especially for major finales like this one. So for now, the best way to watch it is in theaters, with streaming coming a few months later on HBO Max.
