What is Ante-Post Bet?

How an Ante-Post Bet Works

Ante-post markets open well in advance of an event — sometimes over a year out for major races such as the Grand National or Cheltenham Festival, or for football tournaments like the World Cup. Because the field is not yet finalised, bookmakers price up likely contenders early, and those prices tend to be more generous than those available closer to the off. The trade-off is that your stake is at risk from the moment you place the bet.

The key risk is the non-runner rule. In standard ante-post betting, if your selection is withdrawn before the event, your stake is forfeited — you receive nothing back. This differs from day-of-race or match-day markets, where a Non-Runner No Bet (NRNB) rule often applies and your stake is returned. Some bookmakers do offer NRNB ante-post markets as a specific product, but these typically carry shorter odds to reflect the reduced risk. Always check the terms before placing, as rules vary between operators and between sports.

A Worked Example

Suppose a tipster advises backing a horse at 20/1 for the Cheltenham Gold Cup in November, four months before the race in March. You place £10 each-way, staking £20 in total. The horse remains in training, runs, and finishes second. At standard each-way terms of one-quarter the odds for the first three places, your place return is £10 × (20/1 ÷ 4) + £10 = £10 × 5/1 + £10 stake = £60. Your win part of the bet loses, so your total return is £60 against a £20 outlay — a net profit of £40.

Now consider the alternative outcome: the horse is injured in January and is withdrawn. Because this is a standard ante-post market, both the win and place stakes (£20 in total) are lost in full. The tipster's advice was based on sound reasoning at the time, but the non-runner rule means the bet returns nothing. This illustrates why ante-post staking and strike rate figures can look very different from standard betting records.

Why It Matters When Judging or Following a Tipster

Ante-post tipping introduces variables that can distort a tipster's headline statistics. A run of non-runners, particularly in jump racing where injury rates are high, can suppress strike rate and yield figures even when the underlying selections were well-researched. Conversely, a tipster who consistently identifies ante-post value — backing horses at 20/1 that shorten to 8/1 by race day — may show strong closing line value even if winners are infrequent. When reviewing a tipster's record, it is worth checking what proportion of their advised bets were ante-post, and how non-runners have been recorded.

Transparency around non-runners is essential for honest proofing. A reputable tipping service should log every advised ante-post bet at the time it was given, record any non-runners as losing bets, and not quietly remove them from the profit and loss record. If a tipster only counts bets that actually ran, their figures will be misleadingly flattering. At TipsterCheck, we verify that non-runners in ante-post markets are treated as losses unless the tipster explicitly offered advice under NRNB terms and the bookmaker confirmed that rule applied.
