Peacock's achievement eclipses the times set by South African ‘Blade Runner’ Oscar Pistorius and the USA’s Athens 2004 champion Marlon Shirley.
Single leg amputee T44 athlete Peacock, who turned 19 in May, led home a strong field that included Shirley, world champion Jerome Singleton and last year’s Parapan American Games champion Jarryd Wallace.
His time of 10.85 was 0.06 seconds faster than the previous T44 record set in 2007 by Shirley, and was also faster than the 10.91 mark set by T43 sprinter Pistorius the same year.
Second-placed Blake Leeper set an Americas record of 10.95 and became the first American T43 sprinter to go under 11 seconds, while third place went to Richard Browne (11.16).
Peacock’s world record means the men’s 100m T43/44 final on 6 September – also expected to feature reigning Paralympic champion Pistorius, Jerome Singleton and Blake Leeper – is one of the most hotly anticipated events at the London 2012 Paralympic Games.
