Memsie Stakes 2026: Star-Studded Field Set to Launch Melbourne Spring Carnival

The 2026 Memsie Stakes is shaping as one of the strongest editions in recent memory, with a host of Group 1 stars set to return at Caulfield on Saturday, August 29th 2026.

Run over 1400 metres under weight-for-age conditions, the Memsie Stakes is the first Victorian Group 1 of the new racing season and has increasingly become one of the key launching points for horses heading towards the major Spring Carnival features.

This year’s nominations include Mr Brightside, Jimmysstar, Cosmic Crusader, Treasurethe Moment, Buckaroo, Tom Kitten and Autumn Boy, with a maximum field of 16 to be assembled later in the week.

Early betting also suggests there may be no obvious standout, with Cosmic Crusader and Jimmysstar around the $4 mark in early all-in markets.

Cosmic Crusader brings race fitness

Cosmic Crusader is one of the most interesting runners because he arrives with a fitness advantage over many of his rivals.

While a large percentage of the Memsie field will be resuming, Cosmic Crusader has already returned to racing and won the Group 2 P.B. Lawrence Stakes over the same Caulfield 1400m earlier this month.

That immediately makes him a significant betting proposition.

The P.B. Lawrence has historically been a logical stepping stone into the Memsie, and Cosmic Crusader’s performance showed he is capable of competing with high-quality weight-for-age horses.

The market has reacted accordingly, with Cosmic Crusader sitting near the top of early Memsie betting alongside Jimmysstar.

For punters, the question will be whether race fitness outweighs the raw class of several elite horses returning from spells.

Jimmysstar begins another major spring campaign

Jimmysstar is another horse commanding significant early respect.

The Ciaron Maher-trained gelding has established himself among Australia’s better weight-for-age performers and is expected to resume in the Memsie with Ethan Brown booked to ride.

At his best, Jimmysstar possesses the finishing speed required to be extremely effective over 1400 metres.

His first-up record and ability to produce strong closing sectionals should make him particularly dangerous if the Memsie develops into a genuinely run race.

With the early market struggling to separate Jimmysstar and Cosmic Crusader, their contrasting preparations create one of the most interesting betting angles of the race.

Mr Brightside returns to familiar territory

Few horses in Australian racing are as familiar with elite weight-for-age racing as Mr Brightside.

The Lindsay Park star is again set to begin his spring campaign in the Memsie, with Craig Williams expected to ride.

Mr Brightside has an outstanding record at Caulfield and has repeatedly performed at the highest level over distances from 1400m through to 1600m and beyond.

He also knows the Memsie Stakes extremely well.

Mr Brightside won the race earlier in his career and has finished runner-up in each of the past two editions, making Saturday’s contest another logical starting point.

Recent jumpout work has reportedly been encouraging, with Mr Brightside showing plenty of sharpness in preparation for his return.

Punters will need to decide whether they want to back him first-up against younger horses or wait until he reaches his preferred mile later in the preparation.

Treasurethe Moment returns to defend her title

One of the major attractions is the return of Treasurethe Moment, who won last year’s Memsie Stakes before going on to finish third in the Cox Plate.

Trainer Matt Laurie identified the Memsie as the logical starting point for her spring preparation, and she is expected to return with Damian Lane aboard.

Her 2025 Memsie victory proved to be a strong guide to the remainder of the spring.

Treasurethe Moment later finished third in the Cox Plate, while last year’s Memsie third placegetter Buckaroo went on to finish runner-up at Moonee Valley.

That recent history reinforces just how important this race can be for the major spring futures markets.

A strong return from Treasurethe Moment would immediately strengthen her credentials for another Cox Plate campaign.

Autumn Boy switches from Sydney to Caulfield

Autumn Boy adds another fascinating dimension to the race.

The dual Group 1 winner had originally been considered for the Winx Stakes at Randwick but was scratched from that race, with connections instead deciding to launch his spring campaign in the Memsie Stakes.

That move creates considerable interest because Autumn Boy is one of Chris Waller’s highest-profile four-year-olds.

Waller had previously described him as a bigger and stronger horse heading into the new season, and his Memsie performance should provide an immediate indication of where he sits among the country’s established weight-for-age stars.

If he can win or run strongly first-up against this field, Autumn Boy could quickly emerge as a major Cox Plate player.

Chris Waller holds a powerful hand

Waller could have a substantial presence in the final field.

His nominations and likely runners include:

– Autumn Boy
– Angel Capital
– Buckaroo
– Birdman
– Beiwacht

A final decision on some runners is still to be made.

Buckaroo is particularly interesting after finishing third in last year’s Memsie before subsequently running second in the Cox Plate.

Angel Capital is another runner expected to attract attention after connections had been weighing the Memsie against alternative first-up options earlier in the preparation.

The depth of Waller’s nominations demonstrates how seriously the stable is treating the race as an opening spring target.

Planet Red and Sabaj add further depth

Mick Price and Michael Kent Jnr are preparing to run Planet Red and Sabaj.

Planet Red narrowly missed a Group 1 victory in the Australian Guineas during his autumn campaign and is ultimately expected to target races including the Toorak Handicap and Golden Eagle.

Sabaj is being aimed towards the Five Diamonds later in the spring.

Both horses have been preparing through jumpouts, and the stable confirmed earlier this month that the Memsie was the preferred starting point despite acknowledging the exceptional quality of the likely field.

Planet Red in particular could be an interesting runner if the market overlooks him because of the more established names.

Melbourne Cup winner could make surprise appearance

The most unusual nomination is Knight’s Choice.

The Melbourne Cup winner has been entered for both the Memsie Stakes and the Listed Heatherlie Stakes on the same Caulfield card.

Connections had not decided which race he would contest as of the weekend.

A 1400m Group 1 would obviously be well short of his ultimate distance range, so the Memsie would serve primarily as a fitness-building starting point if connections choose that route.

His presence would nevertheless add another Group 1 winner to an already remarkable field.

A major Cox Plate form reference

The Memsie Stakes has become increasingly important for Cox Plate betting.

Last year’s result is the perfect example.

Treasurethe Moment — 1st Memsie Stakes, 3rd Cox Plate
Buckaroo — 3rd Memsie Stakes, 2nd Cox Plate

Mr Brightside, who split them in the Memsie, also went on to perform strongly at Group 1 level later in the spring.

That means Saturday’s race should be watched not only as a standalone Group 1 betting event but also as one of the first major indicators for the 2026 Cox Plate market.

Horses including Treasurethe Moment, Autumn Boy, Mr Brightside and potentially several of Waller’s runners could all emerge from Caulfield with significantly shorter spring futures prices.

Early Memsie Stakes betting

Early all-in markets suggest an unusually open race.

At the time of writing the favourites are:

Cosmic Crusader — $4.00
Jimmysstar — $4.00

with several established Group 1 horses sitting immediately behind them in betting.

Those prices remain subject to significant movement once final acceptances and barriers are known.

The early market essentially presents punters with a choice between race fitness and established Group 1 class.

Memsie Stakes betting outlook

At this stage, Cosmic Crusader looks the obvious horse to use as the early benchmark.

He has already proven himself over the Caulfield 1400m this preparation and does not need to improve dramatically from his P.B. Lawrence performance to be competitive.

Whether $4.00 represents value will depend heavily on the final field and barrier draw.

Jimmysstar may ultimately possess more raw upside, while Mr Brightside’s record means he can never be dismissed at Caulfield.

The most intriguing runner could be Autumn Boy.

His switch from the Winx Stakes to the Memsie indicates connections are comfortable throwing him immediately into a high-quality Victorian weight-for-age race. If he is as improved as the stable believes, he could emerge from Saturday as one of the major horses of the spring.

For that reason, this is a race where waiting for final acceptances and barriers before committing heavily with betting tips may be the best approach.
