Jack Aitken has been confirmed in Cadillac Hertz Team JOTA’s lineup for the FIA World Endurance Championship next year, taking the seat of Jenson Button, who has retired from professional competition.
As first revealed by Sportscar365, Aitken had been linked to the seat in the No. 38 Cadillac V-Series.R, alongside the returning Earl Bamber and Sebastien Bourdais, for several months since Button announced his step back from full-time racing.
The No. 12 Cadillac, meanwhile, will return to the 2026 WEC season with the unchanged lineup of Alex Lynn, Norman Nato and Will Stevens, who combined to score points in every race and place fifth in the Hypercar drivers’ world championship.
Aitken, who has four previous starts in the 24 Hours of Le Mans, including the last three outings in Action Express Racing’s Cadillac, will be making his full-season WEC debut.
“We’re delighted to welcome Jack on board,” said JOTA Sport director and founder David Clark.
“We’ve been following his progress closely this year and have been really impressed by his raw pace and consistency — both essential ingredients for success in the Hypercar category. As an existing member of the wider Cadillac Racing driver family, Jack is a natural fit for us. He already understands the culture, the people, and the expectations within the Cadillac ecosystem.
“Beyond his performance on track, Jack’s calm personality and team-first attitude make him an excellent addition to our driver lineup. We never take team chemistry for granted — six individual stars won’t win endurance races, but six drivers who work as one can.
“Everything we’ve seen from Jack so far shows he embodies that spirit, and we can’t wait to see what he achieves with the team next season.”
Aitken, who got his first laps in JOTA’s Cadillac in last weekend’s Bahrain rookie test, is set to undertake a dual-series program by also competing full-time in the WeatherTech Championship, alongside Bamber, in Action Express’ Cadillac in the GTP class.
It has not yet been announced how the two drivers will tackle the single clashing weekend between the two series on April 17-19, when WEC is at Imola and the WeatherTech Championship races at Long Beach.
Action Express, however, previously confirmed that its third driver Frederik Vesti would be in one of its seats for the street race, indicating that Aitken and Bamber will likely be split up between the two races, and the No. 38 car having a two-driver lineup at Imola as a result.
“I am very appreciative that Cadillac has that trust and are willing to give me the opportunity,” said Aitken. “It’s very exciting for me personally because I’ve never raced in the WEC and I’ve never raced with JOTA, even though we’ve come close a couple of times and have had a relationship that is now coming to fruition.
“They have fantastic people – from the drivers to the staff – and it’s a team that has had success in WEC.
“I’m excited to try to take what I’ve learned in IMSA at Action Express and bring that across to try to push things forward. I’m excited to start the year and to double up on my time in the Cadillac V-Series.R.”
Cadillac Racing program manager Keely Bosn added: “Jack brings exceptional speed, technical insight, and a fierce competitive spirit that perfectly complements the team. Our 2026 roster truly reflects the strength in continuity.
“With drivers competing across both IMSA and WEC, we’re building a unified program that drives shared performance and development. I’m genuinely excited about the depth, talent, and energy this lineup brings to the season ahead.”
