Overview
- NBC confirmed the crossover will air Wednesday, January 13, 2027, from 8–11 p.m. ET/PT and will run across Chicago Med, Chicago Fire and Chicago P.D.
- The three episodes center on an unexpected suspect in the death of a Chicago Med patient and mount a linked criminal investigation that moves between the three shows.
- The crossover was first flagged publicly by cast member Taylor Kinney before NBC issued the formal schedule and storyline details.
- Episodes will be available on Peacock the day after the broadcast, a move aimed at boosting both live ratings and next‑day streaming viewership.
- This marks the third consecutive season to feature a three-show One Chicago event, and the trio remains one of NBC’s strongest Wednesday performers even though formal renewals had not been announced.
