Kipyegon shaved almost an entire second off the previous mark of 3:50.07 set by Ethiopia’s Genzebe Dibaba in 2015.
The world record completes the 29-year-old’s collection of feats, adding to her two Olympic 1,500m golds and the 2017 and 2022 world titles, Commonwealth Games gold medal from 2014 and three Diamond League titles.
The Kenyan remained behind the pacemakers for the first half of the race before racing clear in the final 300m to finish well ahead of Britain’s Laura Muir and Australian Jessica Hull, with her rivals crowding around to congratulate her after the race.
Kipyegon has won both world and Olympic gold on two occasions but this is the first time she has broken the world record. She now holds the first and third fastest times in history, running her previous best of 3:50.37 last August.
