Formula 1 had the unprecedented situation of every starting 2024 line-up being identical to the one each team finished 2023 with.
But the driver market kicked in early this year, and we're already guaranteed plenty of changes for 2024.
Two drivers have already confirmed switches for 2025, one has announced he'll leave his current team at the end of the year, and others have committed to staying put.
Even so, there's still nine seats to be filled before everything is in place.
Below is the 2025 F1 grid as it currently stands.
Red Bull
Max Verstappen
Sergio Perez
Red Bull is sticking with the same driver line-up for a fifth-successive season for 2025, having announced Sergio Perez will continue to partner three-time champion Max Verstappen, whose contract runs until 2028.
That announcement made mention of a two-year contract extension for Perez, but also included team principal Christian Horner quoting only that now was an important time for Red Bull "to confirm our line-up for 2025".
That could indicate that Perez's deal is a one-year-plus-one, with the option for the second year on the team's side. There is also uncertainty over Verstappen's future beyond the end of 2025 amid Red Bull's internal struggles.
Ferrari
Charles Leclerc
Lewis Hamilton
Ferrari's audacious and successful move to lure Lewis Hamilton away from Mercedes kicked the 2025 F1 driver market into gear before the 2024 campaign had even begun.
Seven-time world champion Hamilton joins Charles Leclerc at the team, Leclerc having been announced on a deal covering "several more seasons" in January.
Mercedes
George Russell
TBC
Hamilton's departure means George Russell is at present the only confirmed Mercedes driver for 2025, after which his contract expires.
The team is keen to promote its 17-year-old protege Kimi Antonelli - currently competing for Prema in Formula 2 while conducting a private F1 testing programme - to fill the space vacated by Hamilton.
McLaren
Lando Norris
Oscar Piastri
McLaren was the first team to have its 2025 line-up locked in.
F1's most recent first-time race winner Lando Norris is contracted at the team he's spent his entire top-level career with until at least the end of 2026, as is his team-mate Oscar Piastri - who will be part of an unchanged line-up for a third year in a row in 2025.
Aston Martin
Fernando Alonso
Lance Stroll
Aston Martin is one of three teams that will boast an F1 champion in its 2025 line-up, as 42-year-old Fernando Alonso ruled himself out of the silly season early by committing his future to the team with which he scored eight podiums last season.
We've listed his team-mate Lance Stroll because although his place hasn't been formally confirmed and the details of his contract aren't made public, so far neither Aston nor Stroll are showing any sign of their partnership ending anytime soon.
Alpine
TBC
TBC
Neither of Alpine's drivers for the 2025 season are confirmed.
Pierre Gasly is expected to remain at Alpine beyond the end of this season but Esteban Ocon, who has driven for the team since his return to the grid in 2020 following a year out, will be leaving after 2024.
Ocon, who gave the Enstone team its first and so far only win in its Alpine guise, said in confirming his departure that he will announce his 2025 plans "very soon".
Williams
Alex Albon
TBC
Williams has tied down Alex Albon - who's scored all but five of the team's 38 points in the ground effect era - to a new contract as team principal James Vowles outlines his vision for the team's revival in the coming years.
Who will partner Albon is less clear, but it looks increasingly unlikely to be current team-mate Logan Sargeant - who faces an uphill battle to preserve his place on the F1 grid.
Instead, Vowles has made a compelling enough case - with the financial reward to accompany it - for Williams to be the only serious option for Carlos Sainz beyond the Sauber-run Audi project the outgoing Ferrari driver has long been linked with.
RB

TBC
The second Red Bull team still has two vacancies for 2025.
Perez's new deal marked the official end of Daniel Ricciardo's chances of returning to the main team, though his hopes have gradually faded during what has been, a starring fourth in the Miami Grand Prix sprint race aside, a flat start to 2024.
Red Bull is believed to have an option on his services for 2025, as is the case with his team-mate Yuki Tsunoda. But it also has to find Liam Lawson a drive, otherwise he is - in the words of Red Bull motorsport advisor Helmut Marko - "contractually free to race for another team if he doesn't get a seat with us in 2025".
Sauber
Nico Hulkenberg
TBC
Nico Hulkenberg's career revival at Haas has been impressive enough to catch the eye of Sauber and its CEO Andreas Seidl, with Hulkenberg the first driver signed for the transitional 2025 season ahead of the team's rebirth as the factory Audi team for 2026.
The identity of his team-mate isn't yet known, but it seems all but certain it won't be either of Sauber's current drivers, Valtteri Bottas or Zhou Guanyu. Bottas seems the more likely to stay on the grid and is a candidate - albeit not the top one - for Haas, Williams, and Alpine, while Zhou's options appear slimmer.
Instead, the team is holding out for Sainz's signature to spearhead its project as he moves closer to making a decision between Sauber and Williams.
Haas

TBC
Hulkenberg's exit means Haas currently has two vacancies for 2025, with his team-mate Kevin Magnussen out of contract at the end of the year.
Ferrari protege Ollie Bearman, who starred when standing in for Sainz at the Scuderia back at the second round of the season, seems near-certain to make an F1 graduation for 2025 despite a fairly ordinary F2 season so far with Prema. He will have six FP1 outings with Haas this year.
Should Haas decide not to retain Magnussen for an eighth season, as appears likely, Ocon and Bottas are among the contenders to complete its line-up. Tsunoda, who has been in excellent form so far in 2024 and is 10th in the 2024 drivers' standings, is also known to be of interest to the team.
