The Jack Miller MotoGP exit is official. Confirmation arrived at Aragon on Thursday that the Australian will leave Prima Pramac Yamaha at the end of 2026, closing a grand prix career that has run without a break since he stepped straight from Moto3 to the premier class. His seat goes to Moto2 title contender Izan Guevara, and Miller’s attention has already turned to the World Superbike paddock.
It is a quietly significant moment. Miller has been part of the MotoGP furniture for more than a decade — four race wins with Honda and Ducati machinery, a 23rd career podium claimed with KTM, and a reputation as one of the paddock’s most quotable and least self-pitying operators. That last quality was on display within minutes of the announcement.
The Jack Miller MotoGP exit: “It is what it is”
“It is what it is. It’s the way it goes sometimes,” Miller said at MotorLand. “We’ll keep plugging away, trying to do the best we can until the end of the year. And, obviously, negotiations are going on at the moment of where our future’s going to be.”
There was no bitterness in it, and no retirement talk either. “As I’ve said all along, I want to continue racing,” he added. “I feel like I’ve still got quite a bit of racing left in me. And I feel like I’m still getting better. So we’ll wait and see where our decision lies and what we’re going to do.”
The numbers back him up more than the outcome suggests. Miller was the next-best M1 rider behind Fabio Quartararo in the final season of the inline-four Yamaha, and he holds that same ranking again in the debut year of the marque’s new V4 — a bike that has not yet delivered the step Yamaha wanted. Being second-best on difficult machinery is a thin defence in a market this crowded, but it is not nothing.
Where Miller goes next
The destination looks increasingly like World Superbike. “Obviously all the seats here are full, so looking over at Superbike,” Miller said. “We’ll try to get something solid over there that we can be competitive with and try to build on.” He has form there in all but name: two runner-up finishes at the Suzuka 8 Hours on a Yamaha R1 across the past two years, and a riding style that has never needed coddling. WorldSBK also switches from Pirelli to Michelin rubber in 2027, which removes one variable for anyone arriving from MotoGP.
He has not shut the door on a MotoGP test role either, which is the sort of hedge a rider of his experience is entitled to keep open. What he has not entertained is stopping.
Yamaha’s clear-out is now complete
Miller’s departure is the last piece of a wholesale reset. Quartararo is bound for Honda, Alex Rins is heading to World Superbike, and Jorge Martín — the current championship leader, on the Aprilia — arrives to headline the works effort. Guevara joins Toprak Razgatlıoğlu at Pramac, giving Yamaha a satellite squad built entirely from riders with no more than a season of premier-class mileage behind them. It is youth over experience, deliberately and completely.
Whether that is bravery or impatience depends on how the V4 develops over the winter. What is certain is that Yamaha has moved on from the riders who know what the old bike felt like, at exactly the moment it needs comparative data. Miller, who has spent two seasons providing precisely that, will be watching from somewhere else.

Miller races on at Aragon this weekend with nothing left to negotiate for. On his record, that has rarely made him slower. Quotes via Crash.net.
