Historically, the Alpha Tauri and Red Bull seats are the most volatile in F1. Still, it seems sensible for both teams to maintain their current driver lineups, as explained by Helmut Marko in an interview with formel1.de:
"It can be assumed that the current drivers are set [at Alpha Tauri]. It's correct that they all [Lawson, Vips, etc.] will have to wait for one more year."
Both Alpha Tauri drivers have earned a seat on the 2023 grid, with Yuki Tsunoda setting his rookie season aside and stringing together some respectable performances in 2022.
The youngster is currently a few points ahead of his teammate Pierre Gasly in the standings. Though the Frenchman has been subject to some bad luck this season (and probably still has the pace advantage over the 22-year old), Tsunoda is showing good pace, especially given his inexperience.
Red Bull's current juniors in Formula 2 have shown glimpses of pace but have failed (as of yet) to put themselves in the championship battle and force Alpha Tauri to consider them as F1 candidates for next year.
Pierre Gasly has had a difficult season, owing to various factors, but it would be a stretch to suggest the Frenchman is lacking in pace.
Gasly already has a contract keeping him at Alpha Tauri until the end of 2023, and whilst he might look elsewhere for an F1 seat, another year at the Italian outfit seems most likely for the race winner.
