What is Ante Post betting and how does it work?

Last Updated 14 mins ago | By GrandNational.org.uk | Commercial content | 18+ | Play Responsibly | T&C Apply | Wagering

Grand National ante-post betting allows you to bet on the horse you believe could land the iconic Aintree race weeks or even months before the April meeting. The uncertainty of your horse not running in the National and your bet losing without having a run for your money is factored into the odds. You can typically get better odds the earlier you bet on your fancied runner.

However, you’re at greater risk of losing your stake as the Grand National trainers’ plans for their horses change countless times throughout the season, meaning the Grand National runners list also changes frequently.

What are the advantages of Grand National ante-post betting?

Better odds

Bookmakers know they’ll be offering odds on many horses that don’t make the final 34, which gives them some flexibility on prices. They also know there’s plenty of uncertainty attached to ante-post betting, so we can generally expect prices to be competitive to attract customers.

Better value

The likelihood of getting better value is generally seen as the main reason to place an ante post bet. Perhaps you think a top jockey is likely to ride a particular horse which isn’t factored into its price, or you have a hunch that it’ll be a wet April and know which horse loves running on soft or heavy ground.

Season-long interest

Backing a horse weeks or even months in advance of a race like the Grand National can give you a horse, and indeed a stable, to cheer for throughout the season. Once you’ve backed a horse, you know its odds are guaranteed, so it can be fun watching it perform well over a season, seeing the odds fluctuate and hopefully move in your favour.

No rule 4 deductions

A rule 4 deduction is applied when a horse is withdrawn shortly before a race. This exists to protect those who have backed it as they’ll receive their stake back, but the odds of all the remaining horses are reduced even if your bet has been placed. However a rule 4 doesn’t apply to ante-post odds, so ensuring the odds you’ve taken are guaranteed even if a favourite is forced to withdraw.

What are the risks of Grand National ante-post betting?

Non-runners are losing bets

If for whatever reason (eg, injury, didn’t make the cut, running in another race) your ante post Grand National horse pulls out, the bet is classed as a loser and you will lose your bet without having a run for your money. Tip: Look for bookmakers offering non-runner no-bet (NRNB) promotions before the race, to remove this disadvantage.

Unforeseen events can go against you

The Grand National race distance and fences won’t change. However, the weather leading up to the big race might. If you’ve placed an ante post bet on a Grand National horse that runs better on soft ground, a dry spell means the ground will ride a lot quicker. Other unforeseen events, like jockey or trainer decisions, can also go against you if they fancy throwing their weight behind another horse. Or horses that have run well in key Grand National Trial races may become contenders late on, meaning a market shake-up.

Missing Grand National special offers

Come Grand National day, the rush for business hits top gear as the bookmakers entice punters in with special offers. Layers will generally offer things like refunds if your horse falls, extra place payouts, and refunds if your horse finishes second. However, these will generally only be offered in the days before the big race. These are great safety nets to have on your side. Even if you fail to find the 2024 Grand National winner, you might be lucky enough to get your stake back with a specific offer.

Your money is tied-up

Placing a bet months in advance means you won’t have access to your stake for a lengthy period of time. Not all bookmakers will offer cash-out options on ante-post markets like the Grand National, so be wary of locking up funds that you’d rather have available to bet with.

What are the rules of Grand National ante-post betting?

These are actually pretty simple:

  1. Ante post bets are lost – or deemed a loser – should that horse not make the final line-up. Note: these are not classed as non-runners, they are losing bets which give the bookmakers a significant edge.
  2. Ante post bets are always settled at the price taken at the time of placing the bet. The only time this doesn’t apply is if a particular bookmaker offers ‘Best Odds Guaranteed’. Most firms with that offer will do so on the daily racing and NOT ante post market. This means, should you take 10/1 and the horse drifts out to 14/1 on the day and wins – that ‘Best Odds Guaranteed’ bookmaker will pay you out at the higher odds. But, as mentioned, this will generally apply only to bets you’ve placed on the day of the Grand National.
  3. Non-Runner, No Bet – Be careful here as only certain bookmakers offer this feature. Those that do they will generally only start offering it around 2-4 weeks before the actual race. Once they do the shift of powerheads back in favour of the punter as any bets that are placed on horses that don’t go onto make the final 40 runners will be refunded back into your bookmaker accounts – always check the terms though. On the downside though, once bookmakers offer ‘Non-Runner, No Bet’ you might notice slightly less value odds being offered.

Using the betting exchanges for Grand National ante-post betting

Just like your normal fixed odds bookmakers, the leading betting exchanges will have a Grand National market that operates all year round.

Should you place a back bet on the exchanges on a horse that doesn’t win, you will not be refunded. However, don’t forget, that on the betting exchanges you can also lay horses, place a lay bet on that horse losing. This could now mean not even making the final 40 runners! If you fancied a horse wouldn’t run (or make the final 40), you’ve won on the Grand National before the race has run!

An advantage of using the betting exchanges to place your ante post Grand National bets though would be the option to trade, or cash out in the build-up to the race. If you’ve backed a horse at say 33/1 and after a few good trial races that horse is now come right down in price to say 20/1 then you’ve got a 13 point swing which you could use to lock in a free bet or a certain profit on the race – no matter which horse wins!

Ante post betting example

  • £10 win at 33/1 = £330 profit
  • £10 lay bet at 20/1 = – £200 loss

You’ve now traded your £10 stake back and are risking nothing on the race. However, with the difference between the £330 winning and the £200 loss being £130 then this is the money you’ll win if your fancy goes onto win the Grand National.
