The Arc 2026: the market right now
Daryz is favourite for the Prix de l'Arc de Triomphe 2026 at 7/2 (4.70), ahead of Diamond Necklace at 9/1 (9.80). 20 horses are priced in the antepost market, which is read from the Betfair exchange once a day and has been tracked here for 42 days. The race is run on 4 October 2026 at ParisLongchamp over 1m 4f (2400m).
Diamond Necklace, Maltese Cross, Kalpana have been backed since we started tracking; Minnie Hauk has drifted. Movement is measured against this market's own first reading, not against a bookmaker's board, so it shows where money has actually gone.
These are entries rather than the final field, and ParisLongchamp sits outside our daily racecard, so this page tracks the market rather than promising a scored card on the day.
About The Arc
Autumn ground on the Bois de Boulogne turns it into a test of class AND conditions - the antepost market swings with every big trial through September.
The Arc: your questions
When is the Prix de l'Arc de Triomphe 2026?
The Prix de l'Arc de Triomphe is run at ParisLongchamp on Sunday, 4 October 2026. It is a Group 1 over 1m 4f (2400m), part of ParisLongchamp.
Who are the runners and riders in the Prix de l'Arc de Triomphe 2026?
20 horses are currently in the antepost market for the Prix de l'Arc de Triomphe, listed above with their live exchange price and how it has moved. That list is the entries, not the final field - jockeys are confirmed at declaration time, a few days before the race, and this page swaps to the declared runners with the bot's full scoring the moment they are published.
What are the odds for the Prix de l'Arc de Triomphe 2026?
Every entry's live Betfair price is on this page, updated daily, along with the direction it has moved since we started tracking. Prices before declaration are antepost prices - they will change, sometimes sharply, as the season's trials are run.
Why back the Prix de l'Arc de Triomphe antepost rather than on the day?
Antepost prices are bigger because the risk is bigger - your selection has to get to October fit, in training and declared. What this page adds is the shape of the market over time: a horse that has halved in price since the spring is telling you something a single day's price cannot.
What does antepost mean?
Antepost betting is backing a horse before the final field is declared - often months before the race. Prices are usually bigger than they will be on the day, because there is more that can go wrong: the horse has to stay fit, stay in training and be entered and declared to run.
What happens to an antepost bet if the horse does not run?
On a traditional antepost bet, the stake is lost if your horse does not line up - there is no refund for a non-runner. That is the trade for the bigger price. Markets priced 'non-runner no bet' return the stake instead, and bookmakers usually switch to those terms closer to the race. Check the terms before you bet; we do not place bets and this is not advice.
Where do the odds on this page come from?
Live from the Betfair exchange, read and stored every day. That means the prices here are what people are actually trading at rather than a bookmaker's board, and because we keep every day's reading we can also show which way each horse has moved - the steamers and the drifters - rather than only where it stands today.
Is this page free?
The market, the movers and the entries are free and need no account. What is behind Pro is the bot's own read: each entry's record dialled into the course and distance, and, once the final field is declared, the full 15-signal score on every runner.
