What 60,671 favourites taught me
The favourite is where everyone starts, so it was one of the first things we pulled apart. It won 35% of the time. The useful finding is not that number.
Start where everybody is standing
If you want to know whether a market is any good, you check the part of it that gets the most attention. In racing that is the favourite. It is the horse the money has picked, the horse the previews lead with, the horse most people in the room have an opinion about before the racecard is open.
So that is where we went first. Across 60,671 races with one clear favourite, the favourite won 35% of the time and did not win 65% of the time.
The first time you see that written down it looks like an accusation. Two defeats for every win, from the horse everybody agreed on. There is a version of this article that runs off in that direction, and you have read it before.
Favourite wins 35% · does not win 65% · n = 60,671
That is not what the number says
A horse sent off at 2/1 is not being described as a likely winner. It is being described as a horse that will win about a third of the time and be beaten about two thirds of the time. When it gets turned over, nothing has gone wrong and nobody has been misled. The number did precisely what it said it would do.
Set the 35% against what those prices implied and the gap is small. Small enough that we could not build anything on it. The honest summary of our own headline finding is that the market was broadly right, which is not the summary I was hoping to write.
We went looking for the other version too. If favourites were systematically overrated, that would show up in settled outcomes, so we split them by price band and compared what each band actually did against what its price implied. Short-priced favourites do win more often, almost exactly as often as their price says. The win rate climbs as the price shortens, which is what should happen if the numbers mean anything. What we could not find was a band where the horses were reliably better, or reliably worse, than the figure attached to them.
Why it still feels wrong
Because of how we store racing in our heads, mostly. Three reasons, none of them mysterious.
You remember the beaten ones. A short-priced favourite getting done is an event. The same horse winning is barely a memory by the time you have queued for a coffee. Over a season your recollection quietly fills with defeats and calls itself experience.
Favourite is a label, not a level. An odds-on favourite in a four-runner novice event and a 5/1 favourite in a twenty-two runner handicap are both the favourite. Pool them and you get a strike rate that describes neither race and neither horse. Any number quoted about favourites as a group is doing this to some degree, including ours.
And losing is simply the normal outcome for every horse in the race. In a twelve-runner field, eleven lose. The favourite is not being singled out by fate. It is just the one you happened to be watching.
A market that is broadly right is more interesting than one that is wrong
This took me a while to accept, and I resisted it, because a wrong market is a much better story. If the crowd were systematically daft you would only need to be slightly less daft to profit, and a lot of racing content is built on the hope that this is true.
It is not, at least not in any form we could measure. And once you accept that the price is a good summary of informed opinion, several things stop being worth your afternoon. Betting a favourite because it is the favourite. Opposing a favourite because it is the favourite. Any method whose entire content is a view about whether the crowd has rated the right horse top.
The market is a strong opponent at the thing it does. That is not a reason to give up. It is a reason to stop attacking it head on and start asking what it is not built to do well.
What that leaves
Here is the sentence the whole exercise was worth. If the best horse in a race is beaten about two times in three, and the market already knew that, then which one is best is rarely the useful question. The useful question is what the race is going to ask of it.
A favourite that needs to come from off the pace, in a race where nothing is going to go on and everybody gets a breather down the back, is being asked something entirely different to the same horse in a strongly run contest. A horse that has to lead, drawn where it cannot get across, is being asked something different again. That is not a view about ability. Ability is settled. It is a view about the shape of the event that ability has to be expressed in.
Those interactions are hard to price, which is exactly why they are worth working on. Hard to price is not the same as unknown, and it is certainly not the same as profitable. It is just the part of the racecard where the crowd's enormous collective effort has the least purchase.
Being straight about what this is not
This is a study of outcomes against starting prices across a large sample of races where a single clear favourite could be identified. Races without a clear favourite are a separate question and are not in the figure.
It does not show a way of making money from favourites. We looked hard for one and could not find anything that survived contact with the price actually available at the off. It says nothing whatsoever about what any particular horse will do this afternoon.
