The Biggest Wagers In Horse Racing History: Wins, Losses, High-Stakes Drama
Horse racing has long been known as the “Sport of Kings,” but for some, it’s been the sport of massive gambles—bets involving heart-pounding risk, sky-high stakes, and the potential for life-changing payouts. Over the years, bold bettors have put fortunes on the line, creating legendary moments that have become part of horse racing lore. From record-breaking wins to heartbreaking losses, let’s take a look at some of the most memorable wagers in horse racing history.
1. The $2 Million Bet on "Justify" – 2018 Kentucky Derby
Wager: $2 Million
Location: Churchill Downs, Kentucky
Bettor: Anonymous
Outcome: Won
Payout: $3.6 Million
In 2018, a mystery bettor placed an eye-popping $2 million wager on Justify to win the Kentucky Derby at MGM’s Race & Sports Book in Las Vegas. While Justify was the favorite, the sheer size of the bet made it one of the most talked-about wagers in Derby history.
It paid off in grand fashion. Justify not only won the Derby but went on to capture the Triple Crown—making this bet not just a financial triumph, but a part of horse racing legend.
2. The $10 Million Wager – 2008 Dubai World Cup
Wager: $10 Million
Location: Dubai, UAE
Bettor: Sheikh Mohammed bin Rashid Al Maktoum
Outcome: Lost
Loss: $10 Million
Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai and a major force in global horse racing, made headlines with a $10 million wager on his horse Well Armed in the 2006 Dubai World Cup. Given that Well Armed was viewed as the heavy favorite, confidence was sky high.
However, horse racing is far from predictable and unfortunately for Mohammed, Well Armed finished in seventh, turning one of the largest bets ever into one of its most dramatic losses. While the Sheikh’s wealth allows him to bounce back from such losses, it was a humbling reminder of the sport’s volatility.
3. The $1.5 Million Superfecta – 2007 Breeders' Cup Classic
Wager: $1.5 Million
Location: Santa Anita Park, California
Bettor: Anonymous
Outcome: Won
Payout: $35 Million
One of the most talked about (and lucrative) bets in horse racing history came in 2007 during the Breeders’ Cup Classic. An anonymous bettor placed a staggering $1.5 million superfecta (a bet that requires picking the first four finishers in exact order) on the race. Typically, bettors don’t place massive wagers on these longshots but for this lucky gambler, the result was a mind-blowing $35 million payout. It remains one of the largest single-ticket wins in racing history, a legendary risk that paid off like few others have.
4. The $100,000 Wager – 2003 Belmont Stakes
Wager: $100,000
Location: Belmont Park, New York
Bettor: Steven Crist, Racing Pundit and Author
Outcome: Won
Payout: $600,000
In the 2003 Belmont Stakes, racing expert Steven Crist wagered $100,000 on Empire Maker. Known for his sharp insights and extensive industry knowledge, Crist believed strongly in the horse’s potential to win.
Crist was right—Empire Maker crossed the finish line first, turning his savvy bet into a $600,000 payday. While not the biggest payout ever, it was a masterclass in expert-level wagering.
5. The $50 Million Megabucks Bet – 2003 (with a Horse Twist)
Wager: $50 Million
Location: Las Vegas, Nevada
Bettor: Anonymous
Outcome: Lost
Loss: $50 Million
Though not technically a horse racing bet, this colossal $50 million gamble is often linked to the sport due to the bettor’s ties to horse ownership. A high-stakes player placed the enormous sum on a Megabucks slot machine in Las Vegas, hoping to strike gold.
He didn’t. The entire $50 million was lost, sending shockwaves through the gambling world and reportedly affecting his horse racing ventures. It remains one of the most extreme losses in betting history.
Horse racing has always attracted risk-takers, and these bets exemplify the thrilling—and sometimes brutal—nature of the sport. Whether it's a multimillion-dollar payday or a gut-wrenching loss, each wager tells a story of boldness, belief, and the unpredictable beauty of racing. For those willing to gamble big, the track remains one of the most electrifying places to chase fortune and glory.
