Which Joseph O’Brien Horses Could Run in the 2026 Melbourne Cup?

Joseph O'Brien's Melbourne Cup 2026

Joseph O’Brien is taking a remarkably deep Irish challenge to the Melbourne Cup, but eight names on an entry list do not mean eight runners at Flemington. After Monday’s third declarations, five horses occupy strong positions in the ballot order, three are still looking for a way in, and the Melbourne Cup 2026 odds offer several very different propositions for Irish racing fans.

How Many Melbourne Cup Contenders Does Joseph O’Brien Have?

The third declaration stage on 26 October left 39 horses chasing a place in the 24-runner field. O’Brien retains eight entries, more than enough to attract attention after his victories with Rekindling in 2017 and Twilight Payment in 2020. One has an especially secure position: Defiantly is listed among the ballot-exempt runners. Four stablemates are in the first twelve of the order of entry, although their participation still requires final acceptance.

DefiantlyExempt56.5kg
Sons And Lovers7th57.5kg
Trustyourinstinct9th57kg
Goodie Two Shoes10th55kg
James J Braddock12th53.5kg

Those rankings are an entry advantage, not a published final field. The draw and confirmed riding arrangements will matter when assessing the prices.

Which Irish Runners Are Still Waiting?

Kizlyar sits 27th in the order, with Small Fry 34th and Omni Man 35th. All three remain engaged, but they need the list to move substantially before they can reach the starting stalls. That is the distinction every ante-post punter should make. A promising horse outside the cut-off might shorten in price without ever securing a place. The final 24 and barrier draw are due on Saturday 31 October.

Form, Weights and Jockeys to Watch

Trustyourinstinct won the Curragh Cup and subsequently finished fourth in the Irish St Leger. James McDonald is the anticipated rider, while Dylan Browne McMonagle is linked with Defiantly, whose Prix Kergorlay success secured his place.

O’Brien called Trustyourinstinct “a stayer with a big kick”, an economical description of why the likely pace and draw may suit him.

Goodie Two Shoes was runner-up in last year’s Melbourne Cup, and Wayne Lordan is expected aboard again. Her previous experience around Flemington is valuable in a crowded handicap, where a poor position can quickly undo strong form. Ryan Moore is listed for Sons And Lovers; Craig Williams is the proposed partner for James J Braddock. All riding arrangements require final confirmation.

When Is the Melbourne Cup in Irish Time?

The 3,200-metre race takes place at Flemington on Tuesday 3 November. Irish viewers should expect an early-morning start, but the official off-time has not yet been confirmed. Avoid treating a provisional time as a fixed appointment.

The Verdict

O’Brien has depth, experience and at least one runner with a place effectively secured. Trustyourinstinct looks the most interesting price-versus-profile conversation, while Goodie Two Shoes brings rare course-specific evidence. For Irish punters, wait for Saturday’s final field before making a late move. A generous decimal price means little if the horse never gets a run.
