It's been a long journey to get here, but we have finally arrived. It's the One Chicago crossover, and all signs point to it being the biggest one yet. There is an unprecedented level of integration in this 2025 event, in terms of combining characters from different shows, and we could not be more excited.
It's the sort of event you will want to watch as soon as humanly possible, which is why catching live is going to be so important. You do not want to run the risk of having the OC crossover spoiled for you via Twitter or Threads. Fortunately, there are lots of easy ways to watch the three-part event live.
The One Chicago crossover event will air tonight, Wednesday, January 29. It airs at 7 p.m. ET/PT on NBC, as usual. What is unusual is the fact that Chicago Fire will be kicking off the lineup, instead of Chicago Med. Fire will be followed by Med and then Chicago PD, meaning you'll want to be locked in for all three hours.
Date: Wednesday, January 29
Start Time: 8/7c
Episode: "In the Trenches, Pt. I-III"
TV Channel: NBC
Live Stream: You can watch on the NBC website or app.
NBC live is the easiest way to watch the crossover event live, but you don’t need cable to watch NBC live. FuboTV and Sling TV are streaming options, and you can also tune in through Peacock with the following details:
Stream the crossover event on Peacock
All three One Chicago shows are available to stream on Peacock. It's the quickest and most convenient way to rewatch the crossover event, though you will have to wait until the next day to watch it for the first time.
Episodes head to the streaming platform at 6 a.m. ET/3 a.m. PT the day after they air on NBC, so you’ll be able to watch this on Thursday, January 30. You will also be able to watch previous One Chicago crossovers.
What to expect from the One Chicago crossover
In a word? Absolute chaos. The showrunners from each show, as well as the cast members, have not been shy in claiming that the 2025 crossover is ambitious. There are going to be lots of emergencies and situations that will push characters to the brink.
Chicago Med star Steven Weber drummed up the most excitement for the crossover when he likened it to Avengers: Endgame in scope. "This is like Marvel Endgame, OK? Avengers: Endgame. Everybody is coming in — I'm gonna get the chills — it is such a big ride, it's so good," the actor told NBC. "People are gonna flip out, all right? Everybody hit it out of the park."
