The championship is set to be contested over twenty-four Grands Prix held around the world. It will begin in March and end in December.

The 2025 season is planned to be the last year to utilise the power unit configuration introduced in 2014. A revised configuration without MGU-H but with a higher power output from the MGU-K will be introduced for the 2026 championship. Drivers and teams are scheduled to compete for the titles of World Drivers' Champion and World Constructors' Champion respectively.

The following constructors and drivers are under contract to compete in the 2025 World Championship. All teams are due to compete with tyres supplied by Pirelli. Each team is required to enter at least two drivers, one for each of the two mandatory cars.

Driver changes
After twelve seasons with Mercedes, Lewis Hamilton will join Ferrari in place of Carlos Sainz Jr. This will end Hamilton's record-breaking streak of most consecutive seasons driving for a single constructor, as well as become his first season driving a car without a Mercedes power unit.

Haas will field an all new line-up in 2025; Nico Hülkenberg will depart the team after two seasons and return to Sauber, with whom he last drove in. He will be replaced by their reserve driver Oliver Bearman, who will step up from Formula 2, having previously raced in the 2024 Saudi Arabian Grand Prix for Ferrari. Kevin Magnussen will also depart the team after seven seasons across two stints.

Esteban Ocon will leave Alpine after five seasons with Team Enstone.

Calendar
The 2025 calendar will feature the same twenty-four Grands Prix as the previous season. The Chinese, Miami, Belgian, United States, São Paulo and Qatar Grands Prix will feature the sprint format.

Calendar changes
The Australian Grand Prix will host the opening race of the 2025 season for the first time since. The Australian Grand Prix was the third round in the past three seasons, after the Bahrain and Saudi Arabian Grands Prix, respectively, with those events being pushed back in 2025 to avoid a conflict with Ramadan. The Russian Grand Prix was under contract to feature on the 2025 calendar. However, the contract was terminated in in response to the Russian invasion of Ukraine.
