Antepost betting — placing a wager months before an event takes place — is one of the oldest and most sophisticated forms of sports gambling. The Gold Cup favourite in October might be 5/1. By March the same horse could be 2/1. If you assessed the probability correctly in October, you have a significant edge. The catch: if that horse doesn't run, most bookmakers keep your stake under standard antepost terms.
The Non-Runner Problem
Bookmaker antepost terms on horse racing typically state "non-runner, no bet does not apply" — meaning if your horse is withdrawn injured three days before the race, you lose your stake. Some bookmakers offer NRNB (non-runner no bet) as a promotional offer but charge for it within the price. Understanding the terms difference between standard antepost and NRNB antepost is worth money.
How Prediction Markets Handle Future Events
- →Prediction markets are inherently antepost — they open when an event is first discussed
- →You can trade out of a position at any time before resolution — no "trapped" stakes
- →Non-runner scenarios are handled through market adjustment, not stake forfeiture
- →Long-range political and economic events benefit most from the prediction market structure
Boromarket opens futures markets on major events — elections, championships, awards — as soon as they're worth pricing. Trading a position you opened in October and closing it profitably in February is entirely normal here.
The smart antepost punter uses prediction markets for the trading flexibility and bookmakers for specific events where the terms are NRNB and the price is materially better than the market's implied probability.
