Red Bull will promote Frenchman Isack Hadjar to their senior team and hand 18-year-old Briton Arvid Lindblad a debut Formula 1 season in 2026.
Lindblad, who has a Swedish father and a mother of Indian descent, will be team-mate to New Zealander Liam Lawson at second team Racing Bulls.
The shuffling of Red Bull's driver line-up sees Japanese Yuki Tsunoda lose his seat on the grid after five seasons.
Hadjar, 21, will become four-time champion Max Verstappen's team-mate after an impressive rookie season at Racing Bulls, which included an outstanding podium finish at the Dutch Grand Prix.
