John Patrick McManus, known across the racing world as JP McManus, is an Irish billionaire businessman, former bookmaker and one of the most successful racehorse owners in modern jumps racing. Born on 10 March 1951 in County Limerick, he turned a start in his father’s plant-hire business into a career spanning finance, sport and property. His Wikipedia biography traces that path from small-town beginnings to the top of National Hunt racing.
His green and gold colours have become a defining image of the sport, and his record at the Cheltenham Festival is unmatched by any other owner. Away from the track, McManus is remembered for a major shareholding in Manchester United and for business connections that reach into the upper levels of Irish and British sport.
Despite that public profile, he remains a guarded figure. Most published estimates place his net worth at roughly €2.1 billion, though the exact figure varies by source.

Published estimates place McManus’s fortune at around €2.1 billion, a figure shaped by decades of bookmaking, currency trading and investment alongside one of the largest racehorse operations in jump racing. Business Plus reported that estimate in a profile published around his 75th birthday.
