A member of the Red Bull Junior Team since 2014, Gasly made his Formula One debut with Toro Rosso at the 2017 Malaysian Grand Prix, replacing Daniil Kvyat for the remainder of the 2017 season.

[9] Gasly grew up alongside Anthoine Hubert; karting with him since the age of seven, being educated at the same private school and having resided together as roommates for several years.

[20] He finished third behind his future Eurocup rivals Matthieu Vaxivière and Andrea Pizzitola with seven podiums, including wins at Spa, Albi and Le Castellet.

[26] The driver jumped to Formula Renault 3.5 Series in 2014, where he was hired by Arden under the Red Bull Junior Team development program.

[28] Though taking three pole positions and four podiums, Gasly experienced an uneven season, including causing collisions in Bahrain, Spa and Yas Marina (which got the subsequent race cancelled), which saw him finish eighth, two places behind teammate Lynn.

In December 2013 it was announced that Gasly would be inducted into the Red Bull Junior Team for the 2014 Formula One season alongside future GP2 Series teammate Alex Lynn and future Scuderia Toro Rosso teammate Carlos Sainz Jr.[29] Gasly's first experience in Formula One machinery came in May 2015 at the in-season test at the Circuit de Barcelona-Catalunya.

[32] Gasly made his Formula One race debut at the 2017 Malaysian Grand Prix with Toro Rosso, replacing Daniil Kvyat.

Gasly was contracted to drive for Red Bull Racing for the 2019 season, partnering Max Verstappen following the departure of Daniel Ricciardo to Renault.

[39] His best result with Red Bull Racing came at the British Grand Prix where he finished fourth after Verstappen and Sebastian Vettel collided ahead.

At the German Grand Prix, Gasly retired after colliding with Alex Albon's Toro Rosso in an attempt to overtake for sixth place.

Ahead of the Belgian Grand Prix, Gasly was demoted back to junior team Toro Rosso with Alex Albon taking his place at Red Bull.

[41] Red Bull stated that the swap was made in order to "make an informed decision as to who will drive alongside Max [Verstappen] in 2020",[42] with Horner remarking that "we desperately need [Gasly] realising more of the potential of the car.

"[43] During the remainder of the season at Toro Rosso, partnering with Daniil Kvyat, Gasly achieved five points finishes, including ninth place at his first race back at the team at the Belgian Grand Prix.

At the Italian Grand Prix, an early pit stop allowed Gasly to pass several drivers - who had to wait for the pitlane to open during a safety car procedure - promoting him to third place.

He qualified fourth, dropped to fifth early in the race, but benefited from a tyre failure for Max Verstappen and a mistake from Lewis Hamilton in the closing stages and prevailed in a battle with Charles Leclerc on the penultimate lap to finish third.

[52] At the Italian Grand Prix, Gasly crashed out in sprint qualifying after he made contact with Daniel Ricciardo, wedging his front wing underneath his wheels.

Gasly qualified tenth at the Austrian Grand Prix but collided with Lewis Hamilton in the sprint and Sebastian Vettel in the race, finishing fifteenth.

Gasly had run in seventh place in Singapore, but complained that the team "threw away" this result by switching him to dry-weather tyres too early, dropping him to tenth.

[59] At the Japanese Grand Prix, Gasly criticised the deployment of a recovery tractor in wet conditions to extract Carlos Sainz Jr.'s crashed car, describing it as "disrespectful" to the memory of the late Jules Bianchi and stating "I could have killed myself".

[62] In August and September, information emerged that Alpine were targeting Gasly after Fernando Alonso and Oscar Piastri both left the team, and that Red Bull were willing to release him.

[68] Gasly was in fifth place when racing resumed after the second red flag at the Australian Grand Prix, but collided with Ocon at the first chicane, causing the retirement of both Alpine cars.

[70] Gasly next scored a point at the Austrian Grand Prix, where he finished ninth but was dropped one position for track limits infringements.

He qualified sixth for the Belgian Grand Prix sprint and an early switch to intermediate tyres promoted him to third place, earning six points.

[72][73] Both drivers were again eliminated in the first qualifying session (Q1) at the Saudi Arabian Grand Prix and Gasly was forced into retirement on the first lap of the race with gearbox issues.

Gasly finished no higher than 12th position at the Australian, Japanese, Chinese, Miami, and Emilia Romagna Grands Prix, failing to score points in any of those races.

In June 2024, Gasly extended his multi-year contract with Alpine until at least the end of 2026,[76] this time partnering rookie Jack Doohan in place of the Haas-bound Ocon.

[77] After his success in GP2, Gasly joined Team Mugen, partnering Naoki Yamamoto, to drive a Red Bull-sponsored Honda at the 2017 Super Formula Championship.

[78] He won two races in a row before his season was effectively cut short by the cancellation of the final round at Suzuka Circuit due to Typhoon Lan.

[79] Gasly made a one-off Formula E appearance for Renault e.dams where he replaced Sébastien Buemi for the 2017 New York ePrix, due to the latter's commitments to the World Endurance Championship.
