Gambling often comes with cautionary tales of epic losses—but sometimes, the risk pays off in spectacular fashion. Throughout history, a few daring individuals have placed jaw-dropping bets and walked away with life-changing fortunes. These stories go beyond lucky streaks; they’re bold gambles backed by nerves of steel and, occasionally, incredible timing.
From single-roll wagers worth hundreds of thousands to calculated risks by professionals and billionaires, here are some of the biggest gambling bets and wins ever recorded.
The Biggest Gambling Bets and Wins in History
1. Peter Edwards – £125,000 on a 2,500-to-1 Soccer Bet
In 2000, Peter Edwards placed a £50 bet that his toddler grandson, Harry Wilson, would one day play for Wales’ national soccer team. In 2013, the prophecy came true, netting Edwards £125,000. A humble win by this list’s standards, but unforgettable nonetheless—and he retired the next day.
2. Ashley Revell – $270,600 on One Spin of Roulette
Ashley Revell sold everything he owned and put $135,300 on red at a Las Vegas roulette table in 2004. The ball landed on red 7, doubling his money to $270,600. He cashed out and used the winnings to launch a poker website.
3. Gonzalo García-Pelayo – $1.5 Million from Roulette Bias
Using statistical analysis to exploit imperfections in roulette wheels, Spanish gambler Gonzalo García-Pelayo and his family won over $1.5 million in the 1990s from casinos in Spain and Las Vegas. It was math—not luck—that made the difference.
4. Anonymous British Gambler – ~$4 Million on Red
In 2004, an unnamed British man bet £1.25 million (~$2 million USD) on red at the Plaza Hotel and Casino in Las Vegas. One spin. One win. One instant $4 million payday.
5. MIT Blackjack Team – $5–10 Million Over Years
From the 1980s into the early 2000s, a team of MIT students and math whizzes used card counting to beat blackjack tables across America. Estimates vary, but they reportedly made $5–10 million before getting banned by most major casinos.
6. Don Johnson – $15 Million from Atlantic City Casinos
In 2011, blackjack pro Don Johnson took advantage of special rules negotiated with several Atlantic City casinos. Using skill, patience, and a massive bankroll, he won $15 million in a few months—including $6 million in a single night.
7. Elmer Sherwin – $21 Million Megabucks Jackpot (Second Time)
Elmer Sherwin made headlines in 1989 by winning $4.6 million on a Megabucks slot. Incredibly, at age 92, he won again, this time hitting the $21 million jackpot at the Cannery Casino. He remains the only person known to win Megabucks twice.
8. Archie Karas – $40 Million Run from $50
Archie Karas walked into Vegas in 1992 with $50 and turned it into $40 million over a three-year streak. He dominated high-stakes poker, pool, and dice games before eventually losing it all—but his legendary run still inspires gamblers today.
9. Kerry Packer – $20–40 Million in One Night
Billionaire media mogul Kerry Packer once won $20–40 million in a single night of blackjack at the MGM Grand in Las Vegas. Known for betting $250,000 per hand, he also famously tipped a dealer $1 million.
10. Anonymous Slot Player – $39.7 Million on Megabucks
The largest slot machine win in history happened in 2003 at the Excalibur in Las Vegas. A 25-year-old software engineer from Los Angeles put $100 into a Megabucks machine—and hit the jackpot for $39.7 million. He remained anonymous and chose to receive the money in annual installments.
Final Thoughts
From tiny bets on a toddler’s future to multimillion-dollar jackpots, the biggest gambling bets and wins in history prove that fortune sometimes smiles on the bold, the brilliant, or just the absurdly lucky. But behind every famous win are thousands of losses—so if you do gamble, make sure it’s for fun, not your future.
