I Am Maximus: Can He Win the 2026 Grand National at Aintree?

Few horses in modern Grand National history have carried the weight of expectation into the race the way I Am Maximus does in 2026. The Willie Mullins-trained nine-year-old won the race in 2024 and finished second under top weight in 2025. He has been at or near the front of the market for the 2026 renewal since before Christmas. At 4pm on Saturday April 11th, he will almost certainly be the first horse out of the stalls in the minds of the nation's betting public. Whether he justifies that position is the central question of the Grand National. The Form Case The 2024 Grand National win was authoritative. I Am Maximus, trained by Mullins and ridden by Paul Townend, travelled with menace throughout and asserted his superiority in the closing stages to win convincingly. He returned in 2025 carrying the maximum weight of 11st 12lb — the handicapper's statement that he is the best horse in the race — and finished second to stablemate Nick Rockett, beaten by a horse that was arguably peaking while the favourite was fighting the weights. His most recent run, a second place in the Grade 1 Savills Chase in December, confirmed his ability remained intact heading into this campaign. The form is unquestioned. His RPR of 173 makes him one of the highest-rated horses ever to attempt the Grand National double. At his best, he is a different class from most of his rivals. The Weight Problem The counter-argument is equally clear and historically supported. No horse has won the Grand National carrying more than 11st 10lb in recent renewals. I Am Maximus heads the weights again in 2026 with a mark that places him at or near the top of the burden. In a race of four miles two and a half furlongs over 30 unique fences, the compounding effect of that weight in the closing stages is measurable rather than theoretical. He ran into it last year. The question is whether he can overcome it this year. The trends are unambiguous: top-weighted Grand National favourites lose the race more often than they win it. The statistical record over decades consistently shows that the race rewards horses in the 10st 7lb to 11st range who travel efficiently and finish strongly, rather than class horses carrying maximum weight. What the Market Gets Right The market's position on I Am Maximus is reasonable rather than reckless. His proven course form over the National fences — including a previous win — is the most relevant qualification any horse can carry into this race. His trainer is the most successful Grand National operator of the current era. His jockey won the Gold Cup on Gaelic Warrior three weeks ago and rides with complete confidence. These are genuine advantages that the odds reflect. The Conclusion I Am Maximus is the most talented horse in the 2026 Grand National field. Whether that talent can overcome the weight burden is the question that will be answered at approximately 4:10pm on April 11th.
