A supercomputer has predicted who is most likely to win the 2025 Grand National ahead of the flagship race at Aintree on Saturday afternoon.
Intense Raffles has been predicted to add to his Irish Grand National success from last year by landing the biggest prize in horse racing.
The star – who is trained by Thomas Gibney – is the number one option to win the Grand National.
A British-trained runner in Iroko, who is trainers Oliver Greenall and Josh Guerreiro’s first ever runner in the race, is predicted to finish in second, with recent Cheltenham Festival winner Stumptown backed to finish on the podium.
Last year’s winner I Am Maximus, trained by Willie Mullins, is predicted to finish in fourth place as he attempts to defend his crown.
According to the supercomputer, which was put together by Slingo, Intense Raffles has the best chance of winning the race at 11.4% and landing the huge £500,000 top prize.

Iroko has been handed a 10% chance of winning, while Stumptown and I Am Maximus are both at 8.7%.
The simulation ran 100,000 times using a mix of market odds and rating, which also includes the average winnings.
This is done by giving out the prize winnings after every race and then recording the total amount of money won by that horse after 100,000 simulations.
That is then divided by that many sims to calculate the average amount won by the horse in each simulated race.
Given in the table is the probability of that runner winning, coming 2nd, 3rd and finishing inside the top 10.
The Grand National has changed shape over a number of years, but some big alterations came into effect ahead of the 2024 renewal.
The field size was cut from 40 to 34, the run into the first fence was shortened, the 11th fence was reduced in height, and the start time was brought forward.
However, horses still have 30 fences in total to jump over four miles and two-and-a-half furlongs which lasts just under 10 minutes.
