2026 Kentucky Derby: How Weather, Breeding And AI Could Reshape Horse Racing

Track Conditions: When Weather Becomes The Wild Card

Weather doesn't just determine whether you'll need an umbrella at Churchill Downs, it can fundamentally alter race strategies and winner circle champions.

"When it comes to weather affecting the track, we most often think of precipitation because that is the most easily measured, but all weather affects outcome – wind, temperature and what happens after it rains," explains Ed DeRosa, vice president of content for Horse Racing Nation.

"A track [the] day after heavy rains is a lot different if it's cool and windy while drying out than if it's hot and sunny."

Knowing the race track conditions is one of the first steps when it comes to race day analysis. A dirt track labeled as a “fast” track is the most optimal for running, with a little moisture for cushioning while still providing a solid surface for push off.

Wet conditions mean “off” track winners, such as “sloppy” track winners Justify in 2018 and Sovereignty in 2025, will be the horses that have the mental ability, training experience, conditioning and physical characteristics (such as smaller hooves) to go the distance.

The numbers tell a compelling story. DeRosa went on to say, “In Churchill Downs route races over the past five years, horses running on or near the pace win 29.8% of races on fast tracks, while closers win 20.4%. But when track conditions turn "off" (anything other than fast), those percentages shift dramatically: front-runners jump to 31.9% while closers drop to just 17.6%.”

This statistical shift explains why the 2018 Kentucky Derby became legendary. Not just because Justify won in over three inches of rain, but because the sloppy conditions changed the race dynamics, favoring his front-running style.

"Whether it's a fast or 'off' track is the most important piece of advice," DeRosa notes when it comes to early betting strategy. "Handicappers will examine what the horse has done previously as well as what relatives of that horse have done – they'll use sire stats to see how other progeny by a stallion have done in wet conditions or look at other members in the female family."

The Kentucky Breeding Advantage: Home Field Dominance

Outside of weather conditions, geography might be destiny in thoroughbred racing. Kentucky has produced more than 77% of the Kentucky Derby winners, while other states lag behind: Florida with six winners, and California, Virginia and Tennessee each contributing just four winners.

"Yes, Kentucky has the best stallions and breeds the most horses, so it is unquestionably the top native land of Kentucky Derby winners," DeRosa confirms. "Even two of the three horses shipping to the Derby from Japan and the United Arab Emirates were actually born in Kentucky."

This dominance isn't just about quantity, it's about the unique combination of climate, terrain and generations of breeding expertise concentrated in the Bluegrass State. However, DeRosa cautions against overemphasizing climate adaptation concerns: "Differences in climate are not a huge issue this time of year. The most important thing is to avoid severe weather in the lead-up to the Derby so that you don't miss any training time."

How Trainers Adapt To Weather

The road to the Kentucky Derby starts in mid-September with early prep races at Churchill Downs, and championship series held in Louisiana, Florida, Arkansas and California. So while much of Derby preparation happens months in advance, weather forecasts can trigger last-minute strategic pivots.

"Equipment changes are decided at entry time when weather is mostly unknown, so that's not going to be involved," DeRosa explains. "But things might change in terms of jockey instructions and getting the horse warmed up on the surface."

The most critical moments often occur in the final hours before post time, when trainers must decide whether to adjust racing tactics based on current conditions. For example, a trainer who planned for their horse to sit mid-pack might suddenly instruct their jockey to press the early pace if an “off” track favors front-runners.

"Weather could impact strategy," DeRosa agrees, emphasizing how these real-time decisions can override months of preparation.

AI: The Betting Landscape Changes

Perhaps no factor will reshape the Kentucky Derby’s betting scene more than AI’s growing influence on sports gambling markets. The recent expansion of AI-powered handicapping tools will change how both casual and professional bettors approach race analysis.

"I have a love-hate relationship with AI," admits DeRosa. "I love it because I think it is a powerful research companion. [But] just feeding it rudimentary information or small sample size information is going to lead to what amounts to random picks that may sound smart but aren't."

The key distinction lies in application. "Using AI to distill generations of data into actionable prompts to apply to this year's field definitely has some utility to being a smarter gambler," DeRosa explains.

But relying on AI to make the final decision doesn’t guarantee a win, and is best used to trim the board to a manageable size in your research. As one helpful source states, “It helps pressure-test your own strategy, and gives you a cleaner view of the odds. But it’s not autopilot, the best bettors still pair these tools with their own judgement.”

Looking ahead to potential Derby favorites, DeRosa has identified trainer Brad Cox as a key figure to watch. While Cox won the 2021 Derby after Medina Spirit was disqualified (trained by Bob Baffert), he’s sure to be hungry for an official victory celebration.

"I think this is Brad Cox's year," DeRosa predicts. "Further Ado is the most logical winner of his three contenders, and Fulleffort is a live longshot. I'd like Fulleffort even more if it rains."

Further Ado has one of the highest speed figures, sired by Gun Runner (a successful racehorse that won almost $16 million during his career) and Sky Dreamer (former racehorse who competed on a variety of racing surfaces). He’s won three of six races, and has the bloodlines to finish the distance.

Commandment and Renegade round out some of the early top expert picks. Commandment has won four of his five races including the Grade 1 Florida Derby, and is the third horse in the Kentucky Derby under Brad Cox.

Renegade, trained by Todd Pletcher, was another early favorite though faces an unfavorable position after drawing the number one position against the rail.

Final Thoughts

Weather remains one of the great variables in racing, capable of turning your carefully calculated odds upside down in minutes. And while Kentucky's breeding dominance continues to provide a statistical edge, AI offers unprecedented data analysis capabilities though with limitations that experienced handicappers will need to navigate.

As Churchill Downs prepares for another chapter in racing history, one thing remains certain: “the most exciting two minutes in sports” continues to evolve, blending centuries of tradition with cutting-edge innovation.

Whether you're planning to attend, betting from home or simply watching the spectacle, we can’t wait to experience the rush of adrenaline watching racing's most unpredictable event.
