AI Tipsters, Right and Wrong: 12 Oct to 18 Oct 2026

The longest-priced winner found by any entry in the Silicon Tipster League from Monday 12 October to Sunday 18 October 2026 was Dream Pirate, at 40/1 at Leicester on Tuesday, picked by Gemini (AI Picks the Winner), Gemini (AI Finds the Value Bets), Claude (AI Finds the Value Bets) and others.

The best week belonged to Gemini in AI Picks the Winner, at +8.9% on its stakes from 270 bets.

In all, the League settled 3,658 bets across 285 races, every one logged before the off and settled at starting price, win or lose. 5 of the 14 entries finished the week ahead, and the field as a whole came to -10.1% on its stakes.

Stablebet Edge had the hardest week of the field, and the Favourite, the bar every AI here is measured against, finished it behind.

Below: every entry's week in one table, what each got right and wrong, the race where the AIs split furthest, and how the model's top-rated runners did in the week's biggest races.

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.

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 racingtv.com Handicap at Redcar on Friday 16 October, where their picks named 9 different horses. Uncertainty won it at 40/1, and none of the AIs had picked it. The Stablebet Model had Reginald Charles, which finished 8th.

A split this wide marks an open race, one where the form gave each AI a different horse to argue for.

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.

Qatar Racing British Champions Sprint Stakes (Group 1) at Ascot, Saturday 17 October: the model's top-rated runner, Almeraq, won at 11/10.
Qatar Racing British Champions Fillies & Mares Stakes (Group 1) at Ascot, Saturday 17 October: the model's top-rated runner, Kalpana, finished 7th. Minnie Hauk won at 5/1.
Queen Elizabeth II Stakes (Sponsored By Qatar Racing) (Group 1) at Ascot, Saturday 17 October: the model's top-rated runner, Talk Of New York, won at 3/1.

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 44,784 settled bets over 105 days, the Favourite, which simply backs the market's choice, stands at -11.4%, and the best of the outside AIs on the combined table is Grok at -13.7%. 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.
