This season alone tells the same story. Ninety winners from 625 runners means O'Brien is winning roughly 1 in every 7 races he enters — a 14% win rate that holds up across a huge volume of runners, which is the part that really matters. It is easy to win 1 in 7 when you are picking your spots carefully. Doing it across 625 races means the quality runs deep through the whole operation.
The top-level results are what elevate O'Brien from busy and productive to genuinely elite. Twenty Class 1 wins — the highest grade of race in Britain — at venues including Cheltenham, Sandown Park and Newbury tells you this is not a yard that wins on the lesser stages and disappears when the lights get brighter. A Class 1 win at Market Rasen in January 2026 was followed within a fortnight by another success at Sandown Park, and a Class 1 at Newbury back in March 2025 showed the same pattern: O'Brien tends to show up at the big occasions and leave with the right result.
His most reliable alliance is with jockey Jonathan Burke. Thirty-eight wins from 271 rides together works out to 14% — winning roughly 1 in every 7, exactly matching the yard's overall rate. That kind of consistency across 271 rides is a proper long-term partnership, not a hot streak, and it suggests Burke knows exactly what O'Brien's horses need from him.
One detail worth picking out is O'Brien's record on fast, dry ground. Four wins from just 16 races in those conditions gives him a 25% win rate — winning 1 in 4 — which is significantly better than his already-solid overall numbers. Whether that reflects the horses he targets for those days or something about how the yard prepares them is hard to say, but it is a pattern sharp enough to pay attention to.
