The halls of the J. Edgar Hoover Building are officially staying open. CBS has sent a clear message to fans of the flagship procedural: the New York Field Office isn’t going anywhere. Following a massive multi-season renewal, Season 9 of FBI is locked in, and it’s bringing some of the biggest scheduling changes the franchise has seen in years.
As we move into 2026, the landscape of “FBI Tuesdays” has evolved into a new, high-stakes Monday night powerhouse. Here is everything we know about the premiere and the “shake-up” that is redefining the series.
The Premiere Window: When Does Season 9 Start?
While the current Season 8 is still delivering mid-season thrills through early 2026, CBS has already mapped out the future.
-
Official Timeline: Season 9 is confirmed to premiere as part of the Fall 2026 broadcast season.
-
The Usual Pattern: Barring any industry strikes or unforeseen delays, fans should mark their calendars for October 2026.
-
The Renewal Context: In a rare move, CBS renewed FBI through its ninth season back in 2024, ensuring the show remains a cornerstone of the network through the 2026-2027 television cycle.
The Major Schedule Shake-Up: From Tuesdays to Mondays
The biggest “bomb” dropped by CBS wasn’t a plot point, but a time slot. After years of owning Tuesday nights, the FBI flagship has officially moved to Mondays at 9:00 PM ET.
This move was necessitated by the cancellation of spinoffs FBI: International and FBI: Most Wanted. To fill the void and rebuild the brand, CBS has paired FBI with a brand-new series from the Dick Wolf universe: CIA. Starring Tom Ellis (Lucifer) and Nick Gehlfuss (Chicago Med), CIA is the new companion show that will air immediately following FBI, creating a new two-hour “Justice Block” on Monday nights.
The Season 9 Cast: Who Is Returning?
While Season 8 has been full of “close calls”—including OA’s poisoning scare and Isobel’s health crisis—the core team is expected to remain intact for the ninth outing:
-
Missy Peregrym (Maggie Bell): The emotional heart of the team remains steady.
-
Zeeko Zaki (OA Zidan): Despite the “departure” rumors, Zaki is signed on to lead the action.
-
John Boyd (Stuart Scola): Continuing to balance his new life as a father with high-stakes field work.
-
Juliana Aidén Martinez (Eva Ramos): After a breakout debut in Season 8, she is expected to be a permanent fixture by Season 9.
-
Alana De La Garza & Jeremy Sisto: The “brains” in the command center (Isobel and Jubal) will continue to oversee the chaos.
Why the Shake-Up Matters
CBS is betting big on the flagship show to carry the entire weight of the FBI brand now that the spinoffs are gone. By moving it to Mondays, they are attempting to capture a new audience while keeping the loyal “Tuesday Night” crowd.
The writers have teased that Season 9 will lean more into international intrigue to make up for the loss of the International spinoff, meaning we may see Maggie and OA traveling outside New York more frequently to track global threats.
