Experts vs. AI Revisited: Who will win the 2025 Kentucky Derby?

Artificial Intelligence Large Language Model tools (LLMs) present a growing opportunity for exploration on possibilities for solving research tasks, processes and life’s questions. Names like ChatGPT, Claude, or Gemini emerged over the last three years to become integrated with your daily digital lives.

Naturally, everyone is wondering today how to monetize AI, and horse racing is no exception. Ashley Anderson first explored the emerging ChatGPT interest of 2023 to understand what AI thought of the Kentucky Derby 149. That journey to solve the popular yearly puzzle of ‘Who will win the Kentucky Derby?’ Little did Ashley know that the journey would become the story, and the prediction less so. 

• A.I. cannot simply predict the future
• You can teach A.I. to build a predictive model for the Kentucky Derby
• A.I. can narrow down the most likely Kentucky Derby winner
• A.I. cannot predict the winner, but it can help you figure out the win probability

Fast forward to 2025, what does this year’s Kentucky Derby look like? 

Exploring which horse AI thinks will win the 2025 Kentucky Derby looks much different compared to just two years ago. AI versions have advanced, new tools, and quantum computing in play. The TwinSpires team collected a few questions to test how AI has progressed over the last few years. 

TwinSpires expert racing analysts weighed in on their brief analysis of key questions about the Kentucky Derby and TwinSpires posed the same questions to a trained AI LLM tool. The following comparisons are more reflective of the core question, ‘Who will win the Kentucky Derby?’ and less the journey we had to endure several years ago from Ashley's piece.

Kentucky Derby Question: What was the strongest prep race for the 2025 Kentucky Derby? Please use Brisnet Class Ratings as the primary decision-making factor.

Kellie Reilly: I’d rate the Florida Derby (G1) as the strongest prep. Its interlocking form lines are arguably most informative for the Derby picture, even more so than Journalism’s preps in short fields in Southern California, which were characterized by rivals not running up to form. The key is Florida Derby runner-up Sovereignty. 

When dominating last fall’s Street Sense (G3) in stakes-record time at Churchill Downs, Sovereignty comfortably beat the eventual winners of the Arkansas Derby (G1) and Louisiana Derby (G2) (Sandman and Tiztastic, respectively). In his comeback in the Fountain of Youth (G2), Sovereignty ran down River Thames, with Burnham Square back in fourth. Burnham Square subsequently won the Blue Grass (G1), with River Thames a close third. Earlier in the year, Burnham Square captured the Holy Bull (G3) over Tappan Street, who improved to take the Florida Derby. Adding to the solidity of the Florida prep form is Neoequos, a reliable yardstick who had been chasing last year’s fastest two-year-old, Rated by Merit, in state-bred stakes. 

Kentucky Derby Question: Based on Brisnet E1 and E2 pace ratings, what is the projected pace scenario in the 2025 Kentucky Derby?

Kellie Reilly: On paper, the pace scenario ought to be fast and contentious. The scratch of Rodriguez removes one of the key players, but a few others have aggressive styles. Citizen Bull (who keeps the blinkers on) probably has to go from the rail, and Neoequos has loads of speed right next door in post 2. Fellow pace factor American Promise is likely to be in the early mix as well, and Owen Almighty has to get a semblance of position from the far outside. East Avenue figures to be involved too, although post 12 implies that he could work out an ideal trip rather than be stuck under pressure inside. Sometimes when a pace war appears to be in the offing, it doesn’t materialize, and one speed horse clears the field. I’d still expect an early battle up front, especially given how the draw turned out, but I wouldn’t be totally shocked if it doesn’t pan out that way. 

Kentucky Derby Question: Which 2025 Kentucky Derby entrant has the pedigree to be most effective at 1 1/4 miles?

Vance Hanson: In every edition of the Kentucky Derby, there is no shortage of candidates bred to get 1 1/4 miles. The question always comes down to which one can get the distance in the fastest time. That mixture of speed and stamina would appear to favor the likely Deby favorite, Journalism. But one of the race’s wild cards this year is Luxor Café, a son of Triple Crown winner American Pharoah who has won by open lengths on multiple occasions going 1 1/8 miles in Japan. While it remains to be seen whether he is on par talent-wise with Forever Young, the Japanese colt who narrowly missed winning the 2024 Derby, connections probably wouldn’t ship a horse with any acknowledged distance limitations halfway across the world to compete on such a stage.

Kentucky Derby Question: Which 2025 Kentucky Derby entrant might offer the most betting value? Please use Brisnet Prime Power ratings as a primary decision-making factor, in addition to probable morning line odds.

Vance Hanson: Likely Derby favorite Journalism is ranked only #2 in Brisnet’s Prime Power rankings, with the top spot occupied by Arkansas Derby (G1) winner Sandman. Sandman should offer an attractive price (possibly in the 10-1 to 12-1 range) for an improving colt who would benefit from a hot pace with the right trip. He appears to be a more viable threat than the third or fourth choices on Prime Power, East Avenue and Coal Battle, even though both will be considerably higher prices. Concerns remain about whether East Avenue is a need-the-lead type in a race filled with multiple pace elements, while it did not appear as if Coal Battle would necessarily relish more ground when a weakening third in the nine-furlong Arkansas Derby.

The Artificial Intelligence Large Language Model

Note: the editor had to craft the team’s questions and help train the AI LLM in how to approach answering the following questions. The model needed to be trained on how to discover the information and how to interpret data.

Kentucky Derby Question: What was the strongest prep race for the 2025 Kentucky Derby? Please use Brisnet Class Ratings as the primary decision-making factor.

AI: The Santa Anita Derby (G1) emerged as the strongest Kentucky Derby prep race of 2025, producing an exceptional display of talent and depth. Winner Journalism dominated with a field-best Brisnet Class Rating performance, defeating a quality field that included multiple graded stakes winners. The race's strength was further validated when runner-up Baeza and third-place finisher Westwood both posted strong class figures, creating one of the highest collective ratings for any prep race this season.

The Arkansas Derby (G1) served as the second most impactful prep, where Sandman's victory showcased remarkable class and stamina over the 1 1/8 mile distance. The depth of the field was particularly noteworthy, with Publisher and Coal Battle completing a trifecta that featured three legitimate Kentucky Derby contenders who had previously won or placed in major prep races. The consistently high Brisnet Speed and Class figures throughout the field, combined with the race's historical significance as a final prep, solidified its position as one of the year's premier Derby stepping stones.

Kentucky Derby Question: Which 2025 Kentucky Derby contender has the best closing kick? Please use Brisnet Late Pace as a primary decision-making factor.

AI: Based on Brisnet Late Pace ratings, Journalism stands out as the Kentucky Derby contender with the most impressive closing kick, consistently posting exceptional late pace figures, including a 113 in the San Felipe Stakes and a 109 in the Santa Anita Derby. These ratings significantly exceeded the par ratings for these races (90 and 93, respectively) and were notably higher than those posted by other Derby contenders in their major prep races. The consistency and strength of these closing figures suggest Journalism possesses a superior finishing ability that could prove decisive in the Kentucky Derby's demanding 1 1/4 mile distance.

While other contenders have shown good closing ability, such as Baeza's 102 late pace rating in the Santa Anita Derby and Burnham Square's 100 in the Holy Bull, none have matched Journalism's sustained display of high-end late pace ratings. This closing power has been a key factor in Journalism's success, helping him compile an impressive record of four wins from five starts, including Grade 1 victories in which he demonstrated the ability to effectively close against top-level competition. The combination of consistently high late pace ratings and the visual impression of his finishing ability makes Journalism the most formidable closer in the Kentucky Derby field.

Kentucky Derby Question: Based on Brisnet E1 and E2 pace ratings, what is the projected pace scenario in the 2025 Kentucky Derby?

AI: The 2025 Kentucky Derby projects to unfold with a contentious early pace scenario, as multiple speed elements have drawn into the field. East Avenue, coming off his front-running near-miss in the Blue Grass (G1), brings the most consistent high-level E1 pace figures to the table and appears likely to be prominent from the start. He'll be joined by Citizen Bull and Coal Battle, both of whom have shown high early velocity in their prep races and figure to ensure honest fractions through the opening quarter and half-mile splits.

The presence of several quality pressers, led by Burnham Square and Journalism, suggests the pace will remain strong through the crucial middle stages of the race. These tactical runners have demonstrated the ability to sit just off the leaders while maintaining position through solid E2 pace ratings in their major prep victories. The depth of quality speed in this field, combined with the historical tendency for Derby pace pressure to intensify around the far turn, points toward a legitimate pace that could set up well for horses with proven stamina and the ability to rate effectively in mid-pack positions.

Kentucky Derby Question: Which 2025 Kentucky Derby entrant has the pedigree to be most effective at 1 1/4 miles?

AI: Based on the available pedigree and performance data, Sandman appears to be the Kentucky Derby contender best suited for the classic 1 1/4 mile distance. His sire line shows an Average Winning Distance (AWD) of 7.6 furlongs, while his dam's sire has an AWD of 7.1 furlongs, suggesting strong stamina influences from both sides of his pedigree. Additionally, his running style as a closer who has shown the ability to sustain long runs (as demonstrated in the Arkansas Derby) suggests he will handle the Derby distance effectively.

The combination of his proven stamina in winning major two-turn races, his closing running style (typically positioned in the back half of the field early), and his pedigree metrics (particularly the balanced AWD numbers from both sides of his family) indicates he should relish the added ground in the Kentucky Derby. His victory in the Arkansas Derby at 1 1/8 miles, where he made a sustained run from well back, provides further evidence that the classic distance should be within his scope.

Editor: Who would prove most likely to win the 2025 Kentucky Derby based solely on pedigree factors, Sandman or Journalism?

AI: Based solely on pedigree factors, Sandman appears to have the stronger classic distance breeding for the Kentucky Derby's 1 1/4 miles. He is by Tapit, one of the most influential classic sires of his generation ($185,000 stud fee), out of a Distorted Humor mare. This is a particularly potent combination for stamina, as Tapit has sired multiple Belmont Stakes winners (demonstrating his ability to pass on stamina for 1 1/2 miles), while Distorted Humor on the dam's side adds both class and stamina, having sired Kentucky Derby winner Funny Cide and influenced many other classic performers.

The strength of Sandman's pedigree for the Derby distance comes from the balanced stamina influences on both sides of his pedigree Tapit being a son of Pulpit from the A.P. Indy line (renowned for stamina), combined with Distorted Humor's proven ability to inject classic distance capabilities through the female family. This gives Sandman a pedigree tailored specifically for the classic distances, with multiple sources of stamina influence that have already proven successful at the highest levels of American classic racing.

Editor: How does Luxor Cafe compare to Sandman and Journalism by pedigree, in likelihood to win the 2025 Kentucky Derby?

AI: From a pedigree perspective for the Kentucky Derby's 1 1/4 miles, Luxor Cafe presents an intriguing but slightly different stamina profile compared to Sandman. Luxor Cafe is by American Pharoah ($45,000 stud fee), the 2015 Triple Crown winner who has proven he can pass on classic stamina to his offspring, out of Mary's Follies, a More Than Ready mare. This gives him a fascinating blend of classic stamina through his sire line (American Pharoah being by Pioneerof the Nile), combined with More Than Ready's versatile influence on the dam side.

However, when comparing the three horses strictly on pedigree for the Derby distance:

1. Sandman (Tapit - Distorted Humor mare) rates highest, with proven classic stamina influences top and bottom through Tapit's multiple Belmont Stakes winners and Distorted Humor's classic success.
2. Luxor Cafe (American Pharoah - More Than Ready mare) rates second, with strong classic credentials through his Triple Crown-winning sire, though his dam's side might not be quite as stamina-rich as Sandman's. The key difference is that while both have strong sire lines for classic distances, Sandman's female family through Distorted Humor provides a stronger historical foundation for the Derby distance than Luxor Cafe's More Than Ready influence on the dam side. Both pedigrees suggest they can handle 1 1/4 miles, but Sandman's appears more specifically tailored for classic success.

Kentucky Derby Question: Based on Brisnet Prime Power ratings, which 2025 Kentucky Derby entrant might offer the most betting value?

AI: Based on the available data, Final Gambit appears to offer the most intriguing betting value for the 2025 Kentucky Derby. Despite winning the Jeff Ruby Steaks with a solid 119.4 class rating and showing consistent improvement in his pattern (114.5 to 119.4), he's likely to be overlooked in the betting due to coming from the synthetic track prep route. His impressive late pace figures (112 in his last race) combined with his improving class ratings suggest he's peaking at the right time.

The value proposition comes from the fact that while horses like Sandman (122.9), Journalism (121.5), and Tappan Street (121.4) have posted slightly higher class ratings in their prep wins, they're likely to be bet heavily based on their high-profile victories in traditional dirt preps. Final Gambit's synthetic track form, combined with his strong closing style and improving pattern, suggests he could outrun his odds significantly. While others in the field may have higher absolute ratings, the combination of Final Gambit's improving form, strong late pace figures, and likely generous odds (due to the synthetic track bias among bettors) makes him an attractive value play in the Kentucky Derby wagering.

Editor: Please list the likely order of finish in the 2025 Kentucky Derby, factoring pedigree, speed, run style, and assign a fair odds value for each horse.

• Key factors in ranking:
  • Recent Grade 1 prep performance
  • Progressive form pattern
  • Distance aptitude
  • Running style fit for Derby
  • Connections' Derby experience
  • Pedigree for classic distance
  • Note: These are projected fair odds based on each horse's chances of winning, not predicted actual odds in the betting pools.

Editor: Noting your fair odds assignments, which horse should offer the best betting value?  What are your top 3 best valued horses to bet?

AI: Based on comparing my fair odds assignments to likely actual betting odds, here are the three horses that should offer the best betting value:

• 1. Tiztastic (Fair odds 12-1)
  • Likely to be overlooked despite the Louisiana Derby win
  • Has tactical speed, which is an asset in Derby
  • Asmussen trainee may get overshadowed by bigger names
  • Could be 15-1 or higher, making him an overlay
• 2. Sovereignty (Fair odds 20-1)
  • Godolphin runner with a strong foundation
  • Won the Fountain of Youth impressively
  • Mott trainee could be 25-1 or higher
  • Public may focus more on recent prep winners
• 3. Coal Battle (Fair odds 25-1)
  • Multiple stakes winner at Oaklawn
  • Consistent runner with good tactical speed
  • Lesser-known connections may lead to a big price
  • Could be 30-1 or higher despite solid credentials

These horses offer the biggest gap between their actual chances of winning (reflected in my fair odds) and their likely betting odds, making them the best value plays. The public tends to overbet recent Grade 1 prep winners and big-name trainers, creating overlay opportunities on solid contenders who lack headline appeal.

Kentucky Derby Question: Please rank the top 5 contenders for the Kentucky Derby field, based on Brisnet Speed Ratings earned in 2025 races.

AI: Here are the top 5 contenders ranked by their highest Brisnet Speed Ratings earned in 2025:

• 1. Journalism - 108 (Santa Anita Derby)
     Also earned 104 in San Felipe
• 2. Sandman - 101 (Arkansas Derby)
     Previous high of 95 in Rebel Stakes
• 3. (Tie) Burnham Square - 101 (Holy Bull)
     Most recent 97 in Blue Grass
• 4. (Tie) Final Gambit - 101 (Jeff Ruby Steaks)
     Significant improvement from previous ratings
• 5. Tiztastic - 100 (Louisiana Derby)

Steady progression from the lower 90s. This ranking is based purely on the highest Brisnet Speed Ratings earned in 2025 races. Journalism stands out with multiple high ratings, while Sandman shows a strong upward pattern. It's worth noting that track conditions, pace scenarios, and other factors can influence these ratings.

Editor: Of the top 5 horses listed in ranked speed ratings, which of those horses is most likely to improve or peak?

AI: Among these five horses, Baeza shows the strongest pattern for potential improvement or peaking on Derby day. 

• Here's why:
  1. His speed figure progression (87-93-101) shows a dramatic forward move in his final prep, suggesting he's still developing rather than having plateaued.
  2. His improvement came at 1 1/8 miles, indicating he's getting stronger at longer distances.
  3. Trainer John Shirreffs is extremely patient with all his stock. In all likelihood, this colt hasn't shown his best yet.
• In contrast:
  1. Journalism may have already peaked with that 108
  2. Sandman's progression has been more gradual
  3. Burnham Square's figures have been relatively consistent
  4. Final Gambit's big figure came on the synthetic surface, making it harder to project improvement
  5. The dramatic leap forward in Baeza's last race, combined with the timing of that improvement and his trainer's history of being very patient, suggests he has the best chance of moving forward again on Derby Day.

Kentucky Derby Question: Please rank the top 5 contenders for the Kentucky Derby field, based on Brisnet Late Pace Ratings, listed as LP in a horse’s past performances.

AI: Late Pace ratings would be particularly valuable for analyzing the Derby since they help identify horses who:

1. Can sustain their run through the long Churchill Downs stretch
2. Have the stamina to be effective in the final furlong
3. Might improve at the longer Derby distance

Rather than make up or guess at the LP ratings, I should acknowledge that I cannot see these specific numbers in my data. This would be valuable information for handicapping the Derby, but I want to be accurate in what I can and cannot verify.

Editor: Can you answer those three numbered items by other data and criteria?

AI: Here's the analysis of those three criteria using alternative data:

• Horses showing ability to sustain their run through long stretches:
  • Tiztastic - Won the Louisiana Derby at 1 3/16 miles, longest prep race
  • Sandman - Strong finish to win Arkansas Derby, gaining late
  • Burnham Square - Powerful stretch run to win Blue Grass
  • Tappan Street - Strong finish in Florida Derby win
• Horses showing stamina in final furlong:
  • Tiztastic - Best evidence of stamina, winning longest prep at 1 3/16
  • Baeza - Finished a solid runner-up in the Santa Anita Derby, improving pattern
  • Burnham Square - Strong late energy in Blue Grass
  • East Avenue - Consistently strong finisher in preps
• Horses most likely to improve at longer distance:
  • Baeza - Progressive pattern suggests more distance will help
  • Sovereignty - Grinding style suggests Derby distance will suit
  • East Avenue - Steady closing style indicates distance potential
  • Tappan Street - Into Mischief colt who keeps finding more

Based on these alternative metrics, Tiztastic and Baeza appear most likely to handle the Derby's demanding stretch run, while Burnham Square and East Avenue have shown the consistent finishing ability needed for the classic distance.
