The One Chicago franchise has been a powerhouse in the TV world, captivating fans with its seamless crossovers between Chicago Fire, Chicago Med, and Chicago P.D.. But in 2025, something unexpected is happening—Chicago Fire is kicking off the highly anticipated crossover instead of Chicago Med.
What’s behind this shift? Is it just a creative decision, or is there something bigger at play? Let’s dive deep into the reasons, speculation, and what this change could mean for the future of One Chicago.
🔥 The One Chicago Crossover: A Fan-Favorite Event
💡 What Is the One Chicago Crossover?
For years, the One Chicago universe has treated fans to epic crossover events, intertwining the lives of firefighters, doctors, and detectives in thrilling storylines. These episodes aren’t just standalone specials—they bring high-stakes drama, intense action, and emotional twists that keep viewers hooked.
📅 How the Crossovers Usually Work
Traditionally, Chicago Med sets the stage for the crossover, introducing the medical emergency or crisis that spills over into Chicago Fire and Chicago P.D.. This structure makes sense since hospitals are often the first to respond to major incidents.
So, why the change in 2025?
🔥 Why Is 2025’s One Chicago Crossover Starting With Fire?
🚒 A More Explosive Opening
One major reason Chicago Fire is taking the lead? Pure adrenaline. Firehouse 51 brings some of the most intense action sequences to the franchise, and opening with a high-stakes emergency could immediately grab viewers’ attention.
🔥 A Fresh Storytelling Approach
After years of following the same crossover format, the showrunners may have wanted to shake things up. By starting with Chicago Fire, the narrative flow could feel fresh and unpredictable—keeping fans on their toes.
📺 Ratings & Audience Engagement
Chicago Fire has consistently been the highest-rated show in the franchise. Kicking off the crossover with its most-watched series might be a strategic move to maximize viewership and ensure a strong start.
🎬 Production & Scheduling Factors
Behind the scenes, logistical reasons might also play a role. Filming schedules, actor availability, and even external events (like real-life emergencies affecting production) could have influenced the decision.
🚑 Why Is Chicago Med Taking a Backseat?
👨⚕️ A Shift in Medical-Focused Storylines
Perhaps the upcoming crossover doesn’t require Chicago Med to be the starting point. If the main crisis originates outside of a hospital setting, it makes sense for Chicago Fire to introduce the storyline first.
📉 Declining Viewership?
While still popular, Chicago Med has seen slight dips in ratings compared to Chicago Fire and Chicago P.D.. This switch could be a way to re-engage fans and bring fresh energy to the franchise.
🎭 Character Arcs & Creative Direction
The One Chicago writers are known for their intricate storytelling. If a major character’s arc is set to unfold dramatically in Chicago Fire, it makes sense to start there instead of in the ER.
🔥 How This Change Could Impact the One Chicago Universe
📢 More Unexpected Crossovers
If this format works well, we might see future crossovers start in unexpected places—maybe even Chicago P.D. leading a storyline someday.
🚀 A Faster-Paced Narrative
Starting with Chicago Fire means the action kicks off immediately, which could lead to a more fast-paced and thrilling crossover event.
🎬 Potential for Bigger Cliffhangers
With Chicago Fire opening the crossover, the transition into Chicago Med could come with an even bigger, jaw-dropping cliffhanger, keeping fans glued to their screens.
🔥 What Fans Can Expect in the 2025 One Chicago Crossover
👀 A High-Stakes Fire

⚖️ A Complex Investigation
Chicago P.D. is likely to take a deep dive into the cause behind the emergency—was it arson? A criminal act?
❤️ Emotional Storylines
No One Chicago crossover is complete without emotional turmoil. With Chicago Fire leading, we could see one of our favorite firefighters in serious danger.
🔄 A New Cross-Show Dynamic
Starting with Chicago Fire could change how characters interact across the three shows, leading to new alliances and conflicts.
🔥 Will This Be a Permanent Change?
🤔 Testing the Waters
NBC may be experimenting with this new format to see how audiences react. If it’s a hit, we could see more varied crossover structures in the future.
📊 Viewer Reactions Will Decide
If ratings spike, this could become the new normal. If fans push back, we might return to the old Chicago Med-first formula.
📝 Lessons from Other TV Universes
Shows like the Arrowverse have changed crossover formats multiple times based on fan feedback. One Chicago might follow suit.
🔥 Final Thoughts: A Bold Move for One Chicago
The decision to start the 2025 One Chicago crossover with Chicago Fire instead of Chicago Med is a bold move, but one that makes sense. It injects fresh energy, delivers high-intensity action from the get-go, and could signal a new era for the franchise.
