Supercomputer predicts Grand National winner with '95 per cent chance of winning'

A supercomputer has predicted the winner of the 2025 Grand National ahead of the big race.

On Saturday at 4pm, all eyes will be fixated on Aintree as 34 horses set off for the 4 miles 2 1/2 furlongs event.

Last year's winner, I Am Maximus, is the bookies' favourite to defend his title and will be ridden by Paul Townend.

Meanwhile, the likes of Iroko, Perceval Legallois, Stumptown and Hewick are all well-backed.

Rachael Blackmore will be onboard Minella Indo, who has been priced at 14/1 by the bookies. (Odds were correct at the time of writing)

Ahead of the race, experts at grandnational.org.uk have used a supercomputer to work out the winner.

Characteristics of past champions from 1992 to last year have been analysed, taking into account the race distance, recent performances, breeding, trial races and current odds to come to their decision.

The supercomputer has said that Intense Raffles has a 95 per cent chance of glory and has been given a 0.87 rating for similarities to previous National winners.

Iroko has been given a 94 per cent chance of winning with outsider Monbeg Genius tipped to finish third.

Perceval Legallois has been predicted to come home fourth, with Stumptown fifth.

Meanwhile, defending champion I Am Maximus has been put in a disappointing eighth place.

Top 10 finishers of the 2025 Grand National according to the supercomputer

1. Intense Raffles
2. Iroko
3. Monbeg Genius
4. Perceval Legallois
5. Stumptown
6. Three Card Brag
7. Hyland
8. I Am Maximus
9. Vanillier
10. Kandoo Kid

National winning jockey Mick Fitzgerald has backed Iroko to get the job done.

He said to Sky Sports: "I think one of the speciality bets is JP McManus to win the race. Just I Am Maximus and Iroko alone are well fancied.

"I went back and watched I Am Maximus again to remind myself how good he was last year. You have to factor in that it's drier ground this year and he hasn't had as good a preparation.

"For that reason, when you look at Iroko's form, he was second to Inothewayurthinkin - the Gold Cup winner. The drier the ground, the better it is for Hewick's chance and he comes here in good form."
