The longest-priced winner found by any entry in the Silicon Tipster League from Monday 5 October to Sunday 11 October 2026 was Grey Cuban, at 28/1 at York on Saturday, picked by Grok in AI Finds the Value Bets.

The best week belonged to the StableBet Rating, our own figure backing its top-rated horse in handicaps, at +14.5% on its stakes from 170 bets.

In all, the League settled 3,838 bets across 301 races, every one logged before the off and settled at starting price, win or lose. 2 of the 14 entries finished the week ahead, and the field as a whole came to -18.2% on its stakes.

Stablebet Model held up well, while Claude had a hard time. The Favourite, backing the market choice, finished behind.

Every bet is a level stake at starting price. A non-runner returns the stake and is not counted as a bet. Return on stakes is the week's gain or loss per pound staked, and the full-record column is the same figure over every settled bet since the League began, updated every day. 1 picks still waiting on a result are not counted yet.

Where the AIs split furthest

The outside AIs pick twice in every race, once in each test. The widest split of the week came in the Book Your Discounted Tickets On NavanRacecourse.ie Handicap (0-60) at Navan on Wednesday 7 October, where their picks named 7 different horses. Rosato won it at 7/2, picked by ChatGPT (AI Finds the Value Bets) and Claude (AI Picks the Winner). The Stablebet Model had Verified, which finished 12th.

Such a wide split suggests a race with many potential outcomes, even for the AI systems.

The model in the week's biggest races

The model rates every runner in every race on the card. These are the week's highest-graded races in our feed, with the runner it rated most likely to win in each and how that runner finished. Its full settled record is on the Track Record.

Bet365 Fillies' Mile (Group 1) at Newmarket, Friday 9 October: the model's top-rated runner, Musical Times, won at 4/9.
Darley Dewhurst Stakes (Group 1) at Newmarket, Saturday 10 October: the model's top-rated runner, Desert Castle, finished 2nd. Darkness Falls won at 6/4.
DragonBet Persian War Novices' Hurdle (Grade 2) at Chepstow, Friday 9 October: the model's top-rated runner, Lord Byron, finished 6th. West Hill Verde won at 16/1.

The longer record

A week is a small sample, and a good week is something a losing approach produces some of the time. On the League's full record of 41,126 settled bets over 98 days, the Favourite, which simply backs the market's choice, stands at -11.9%, and the best of the outside AIs on the combined table is Grok at -14.8%. Those figures move every day. The standings are on the Silicon Tipster League, the value test has its own table, and every settled pick of our own model is on the Track Record.
