Estimate (foaled 4 April 2009) is an Irish-bred, British-trained Thoroughbred racehorse who won the Queen's Vase at Royal Ascot as a three-year-old.

[2] Ebaziya was trained by John Oxx and won three Listed races in Ireland, including the Ballysax Stakes.

[4] The 2009 produce of Ebaziya was made available to Queen Elizabeth II as part of an 80th birthday present from the Aga Khan.

Saddler's Rock led the race for the first few furlongs, with Estimate, ridden by regular jockey Ryan Moore, near also near the front.

Moore asked for an effort as they turned into the finishing straight and took the lead from Colour Vision with one furlong still to run.

[17] On her only subsequent appearance in 2013, Estimate started 2/1 favourite for the British Champions Long Distance Cup at Ascot on 19 October, but made no impact, finishing seventh of the twelve runners behind Royal Diamond.

She suffered from muscular problems in her right hind leg and Stoute was unable to give her a trial race before she ran in the Gold Cup on 19 June.

In a closely contested finish she was beaten into second place, a neck behind the 2013 St Leger winner Leading Light.

On 12 September Estimate started the 11/8 favourite for the Doncaster Cup against eleven opponents headed by Time's Up, who had won the last two runnings of the race.

She took the lead from Brass Ring approaching the final furlong and held on in the closing stages to win by one and a quarter lengths from the six-year-old gelding Whiplash Willie with the 80/1 outsider Kalann in third.

[21] On her final racecourse appearance the mare ran for the second time in the British Long Distance Cup and started at odds of 8/1.

Estimate was retired to the Royal Stud at the end of that season and the following Spring covered by Dubawi by whom she had a colt foal in early 2016.
