Night Of Thunder's €450,000 Stud Fee: Why It's a European Record

Night Of Thunder stud fee: €450,000 for 2027

The Night Of Thunder stud fee for 2027 is €450,000, more than double his 2026 fee of €200,000. Darley released it on November 9, 2026, and BloodHorse calls it the highest publicly advertised stallion fee in European history.

He stands at Kildangan Stud in County Kildare, Ireland. Breeders pay that sum to send one mare to him, and the fee normally depends on a live foal.

If you're new to how that works (live foal terms, payment dates, "stands and nurses"), our explainer on how stud fees work covers the basics. This article sticks to why this horse, and why now.

Darley 2027 stud fees: the headline numbers

Night Of Thunder tops a 23-stallion roster across Ireland, England and France. These are the fees that matter most for this story:

Two of the newcomers are his own sons:

• Bow Echo retired unbeaten after winning the 2,000 Guineas, St James's Palace Stakes and Sussex Stakes. Darley says he's only the third horse to complete that treble unbeaten since the Pattern began.
• Ombudsman has won five Group 1 races, including back-to-back Prince of Wales's Stakes and the Champion Stakes. Darley calls him the highest-rated horse his sire has produced. Read more in our Ombudsman profile.

Who is Night Of Thunder?

Night Of Thunder is an Irish-bred chestnut foaled in 2011, by Dubawi out of the Galileo mare Forest Storm. Trained by Richard Hannon, he won both his starts at two.

At three he won the 2,000 Guineas at Newmarket in 2014, beating the favorite Kingman by half a length. At four he took the Group 1 Lockinge Stakes by a neck.

His stud career had a modest start:

• 2016: first season at Kildangan for €30,000.
• 2018-2019: two seasons at Dalham Hall in Newmarket, before returning to Kildangan.
• 2019: champion first-season sire.
• 2025: British and Irish champion sire for the first time.
• 2026: champion sire again, with six Group 1 winners and his 100th individual stakes winner.

His best runners include Highfield Princess (a top sprinter who won the Nunthorpe and the Prix de l'Abbaye), Ombudsman, Economics, the 1,000 Guineas winner Desert Flower, the champion 2-year-old Gewan and Bow Echo.

Why a stud fee can double in one year

Stallion farms set fees for what the market will pay, not for what the horse earned on the track. Three things pushed this one up fast.

1. His runners keep winning the biggest races

Six Group 1 winners in one season is elite form. Two champion sire titles in a row tell breeders it isn't luck.

2. His yearlings sell for many times his fee

At Tattersalls' Book 1 sale in October 2026, Godolphin paid 4.6 million guineas for a Night Of Thunder colt out of My Astra. Tattersalls called it a European record for a yearling colt and the highest yearling price anywhere in the world this year. See our Tattersalls October sale report.

That colt wasn't alone: Sporting Life counted at least five seven-figure Night Of Thunder yearlings that week. When foals routinely sell for far more than the fee, breeders will pay more, so a stud can raise the price. A sale above the fee isn't the same as a profit, though: mare keep, vet bills, sales costs and transport come out of it too.

3. Top mare owners want in

A stallion only covers a limited number of mares a year. When the best broodmare owners all want a slot, the fee becomes a rationing tool.

Is he really the most expensive stallion in Europe?

In advertised numbers, yes. But comparing fees across borders is trickier than the headline suggests:

• VAT is in some prices and not others. Irish fees include 13.5% VAT. British and French fees are quoted without it. Strip the VAT out and Night Of Thunder's €450,000 is roughly €396,000.
• Different currencies. Dubawi's £350,000 is in pounds and quoted without UK VAT. A mare owner based in the UK pays 20% VAT on top; one in business outside the UK isn't charged it. Exchange rates move the gap every week.
• Some fees are "private." Farms can decline to publish a fee. On Darley's own list, Farhh stands at a private fee. A private fee can't be ranked at all.
• Frankel's 2027 fee: Juddmonte announced on November 9, 2026 that Frankel stays at £350,000 (1st October, special live foal), the same as in 2026.

So the fair way to say it: €450,000 is Europe's highest publicly advertised fee. Once VAT and exchange rates are counted, he sits in the same tier as Dubawi and Frankel rather than miles above them.

Not the same €450,000: the July nomination auction

In July 2026, Darley ran an online "Winning Bid" sale of breeding rights. One nomination (the right to send one mare) to Night Of Thunder for 2027 sold for €450,000.

That was an auction price for a single slot, not the published fee. The two figures happen to match, and the auction was an early sign of how much breeders would pay.

What to watch next

• November 29: Ombudsman runs in the Japan Cup in Tokyo, his planned final race before stud.
• 2027 yearling sales: watch Tattersalls and Arqana to see whether his foals keep fetching multiples of his old fee.
• Bow Echo's first book: at £65,000, he's a test of whether Night Of Thunder can found a sire line.

A quick checklist for reading any fee headline

1. Is the fee with or without VAT?
2. Which currency, and on what date?
3. Live foal terms, or payable regardless?
4. Is it a published fee, a private fee or an auction price?
