One of the crown jewels of F1's calendar, Monaco's contract was up for renewal after the 2025 edition.
There had been doubts about Monaco's long-term future of the race given its notorious struggles to provide an entertaining race on the narrow streets of the principality, but F1 and the Automobile Club of Monaco have now struck a deal that will see the race remain on the calendar for six more years.
Monaco will change dates under its new deal, moving from its traditional end-of-May date to the first weekend of June from 2026 onwards. That means it will no longer clash with the Indianapolis 500.
“I’m delighted that Formula 1 will continue to race in Monaco until 2031," said F1 CEO Stefano Domenicali. "The streets of Monte Carlo are unique and a famous part of Formula 1, and the Monaco Grand Prix remains a race that all drivers dream of winning.
"I would like to extend a special thanks to H.S.H. Prince Albert II of Monaco, Michel Boeri, President of the Automobile Club of Monaco and everyone involved in the extension of this important partnership."
Monaco is understood to fork out a significantly higher sanctioning fee to remain on the calendar. But the race's commercial prospects have been boosted by F1's recently announced deal with luxury conglomerate LVMH.
As part of the deal, TAG Heuer will take over from Rolex as F1's official timekeeper next year. TAG has also been a long-standing partner of the Monaco race, which means its branding will no longer clash with F1's, something which had been a point of discussion when Monaco's previous contract extension had to be negotiated.
The Monaco Grand Prix featured on the first F1 world championship calendar in 1950 and has been a regular fixture since 1955.
It is understood that F1 has now accepted that due to the tight confines of the Monte Carlo harbour, Monaco's contested 3.3km layout is not expected to change throughout the new deal.
