The World's Most Expensive Casino Bets: Record-Breaking Wagers That Made History
Every gambler dreams of placing that one life-changing bet. But for a select few, the stakes have been almost unimaginable. From a British man who sold everything he owned to bet it all on a single roulette spin to billionaires who wagered millions on single hands of baccarat, the history of gambling is punctuated by moments of extraordinary financial audacity.
These record-breaking wagers reveal something fundamental about human psychology: the intoxicating mix of risk, reward, and the thin line between courage and recklessness. The stories behind history's most expensive casino bets are tales of desperation, calculation, showmanship, and sometimes, pure luck.
Ashley Revell: The Man Who Bet Everything on Red
On April 11, 2004, a 32-year-old British man named Ashley Revell walked into the Plaza Hotel and Casino in Las Vegas and made what remains one of the most famous single bets in gambling history. He placed $135,300 on a single spin of the roulette wheel. The catch? That $135,300 represented literally everything he owned.
Revell had sold his house, his car, his clothes, his golf clubs, and every possession he had accumulated in his life. He even sold his watch. The entire journey was documented by the British television show "Double or Nothing," which followed Revell as he liquidated his life for one extraordinary gamble.
At the roulette table, with cameras rolling and a crowd gathering, Revell placed his entire stake on Red. The ball spun, bounced, and finally settled into Red 7. Revell had doubled his money to $270,600 in about 20 seconds. According to Britannica's analysis of roulette, his bet had approximately a 48.65% chance of success on the American wheel used—making his win genuinely remarkable.
What did Revell do with his winnings? He didn't continue gambling. Instead, he used the money to start an online poker company called Poker UTD. The company eventually failed, but Revell has maintained he has no regrets. His bet became a cultural touchstone, referenced in movies, TV shows, and countless discussions about the nature of risk.
William Lee Bergstrom: The Phantom of Horseshoe
Before Ashley Revell, there was William Lee Bergstrom—a mysterious figure who became legendary for the largest single craps bet in casino history. On September 24, 1980, Bergstrom walked into Binion's Horseshoe Casino in Las Vegas carrying two suitcases. One contained $777,000 in cash. The other was empty.
Bergstrom was taking advantage of Binion's famous policy: they would accept a bet of any size, as long as it was your first bet. He placed the entire $777,000 on the Don't Pass line—betting against the shooter. The shooter threw the dice. They came up 7 on the first roll, a loss for the Pass line. Bergstrom's Don't Pass bet won.
He calmly loaded $1.554 million into both suitcases and walked out of the casino. The entire transaction had taken less than five minutes. Bergstrom's identity remained unknown for years; the casino called him "The Phantom Gambler" or "The Suitcase Man."
Bergstrom wins $777,000 on a single craps bet at Binion's Horseshoe, the largest recorded at the time.
Bergstrom returns with $538,000 and wins again. A few months later, he returns with $1 million—and loses.
Ashley Revell bets $135,300—his entire net worth—on a single roulette spin and wins.
A Macau businessman reportedly wagers $11 million on a single baccarat hand.
Bergstrom returned to Binion's twice more. In early 1984, he won another $538,000 on a similar bet. Emboldened, he came back a few months later with $1 million—the largest single bet the casino had ever accepted. This time, the shooter threw a 7 before making the point. Bergstrom lost.
The loss devastated him. William Lee Bergstrom took his own life in February 1985 at the Las Vegas Hilton. His story serves as a sobering reminder of the psychological toll that can accompany high-stakes gambling, a theme explored in our coverage of famous gambling addicts.
Kerry Packer: The Whale Who Tipped in Millions
Any discussion of the most expensive casino bets must include Kerry Packer, the Australian media billionaire who was perhaps the most legendary casino whale in gambling history. Packer didn't just make expensive bets—he made them routinely, sometimes winning or losing $20 million in a single night.
Packer's betting style was unprecedented. At the MGM Grand in Las Vegas, he would regularly play eight blackjack hands simultaneously at $250,000 per hand—$2 million at risk on every deal. During one famous session, he reportedly won $20 million playing blackjack over three nights. On another occasion, he lost $28 million at baccarat in a single week at a London casino.
"When I walk into a casino, I want them to know who I am. And I want them to be afraid." — Kerry Packer, as quoted by casino industry sources
According to the American Gaming Association's historical records, Packer's betting levels forced casinos to rethink their risk management strategies. Some properties would decline his action during quarterly reporting periods to avoid earnings volatility. Others competed aggressively for his business, knowing that a Packer visit could make their entire quarter.
Packer was famous for his generous tips and memorable gestures. When a cocktail waitress mentioned she had credit card debt, he reportedly paid it off on the spot. When a blackjack dealer at the Stratosphere was rude, Packer switched to the Bellagio and won $12 million—then reportedly called the Stratosphere to remind them what they'd missed.
Archie Karas: The Run and The Fall
Archie Karas didn't make a single record-breaking bet—he made thousands of them over the course of what gamblers call "The Run," a three-year winning streak from 1992 to 1995 that remains the most remarkable in gambling history.
Karas arrived in Las Vegas in December 1992 with $50. By borrowing $10,000 from a friend and playing high-stakes poker, he ran that stake up to $17 million. Then he switched to pool and dice, continuing his incredible winning streak. At his peak, Karas had won approximately $40 million—a documented gambling fortune assembled one bet at a time.
The end came just as dramatically as the beginning. Karas lost his entire $40 million fortune in three weeks, primarily at baccarat and dice. The UNLV International Gaming Institute has cited Karas's story as a cautionary tale about the mathematics of gambling: no matter how skilled or lucky a gambler may be, continued play against a house edge eventually leads to losing everything.
Karas later fell on harder times. In 2013, he was banned from all Nevada casinos for life after being caught marking cards at a blackjack table—a fall from grace that echoed the stories in our coverage of famous casino cheating devices.
The Baccarat Billions: Macau's Ultra-High-Stakes World
The truly astronomical bets happen not in Las Vegas but in Macau, where baccarat is king and the stakes routinely dwarf anything seen on the Las Vegas Strip. According to data from the Gaming Inspection and Coordination Bureau of Macau, the city's casinos generate more revenue than Las Vegas, primarily from VIP baccarat rooms where minimum bets start at $100,000 per hand.
In these private rooms, bets of $5 million, $10 million, and even $20 million on single hands are documented. The players are typically mainland Chinese businessmen whose identities are carefully protected by casinos and junket operators. The amounts at stake are so large that a single player's results can materially affect a casino's quarterly earnings.
One documented case from 2015 involved a Hong Kong property developer who lost approximately $40 million in a single night of baccarat at a Macau casino. The loss was large enough to require disclosure in the casino operator's financial filings. In the ultra-high-stakes world of Macau VIP gambling, such nights—while unusual—are not unprecedented.
The mathematics of these massive bets are straightforward, as you can explore with our Baccarat Odds Calculator: even the Banker bet, with its relatively low 1.06% house edge, becomes ruinous when millions are wagered repeatedly. The casinos understand this; the only question is how long the player's fortune will last.
Record Sports Bets: When Gambling Meets Athletics
While casino table games produce dramatic single bets, the sports betting world has its own record-breakers. Professional sports bettors like Billy Walters have reportedly placed bets exceeding $3 million on single NFL games, though the details are often murky due to the use of multiple sportsbooks and agents.
One verified record came in 2024 when Mattress Mack (Jim McIngvale), the Houston furniture magnate, placed $10 million on the Houston Astros to win the World Series at Caesars Sportsbook. The bet was part of a promotional strategy tied to his furniture business, but it represented a genuine financial risk—one that McIngvale ultimately lost.
The Reuters sports business coverage has documented how legalized sports betting in the United States has increased both the number and size of maximum bets accepted by licensed sportsbooks. Where illegal bookmakers once dominated high-stakes sports betting, regulated casinos now compete for the action of wealthy bettors.
The Psychology Behind Record-Breaking Wagers
What drives someone to bet everything on a single spin of the wheel? The psychology of extreme gambling has been studied extensively by researchers. Several factors consistently appear in the profiles of record-breaking bettors:
Risk tolerance: Some individuals have naturally higher tolerance for risk, often combined with reduced sensitivity to losses. Research from the American Psychological Association suggests these traits have both genetic and environmental components.
The illusion of control: Many high-stakes bettors believe, often incorrectly, that they have some edge or insight that improves their odds. This is particularly common in poker and sports betting, where skill genuinely matters—but also in pure chance games like roulette, where no such edge exists.
Excitement-seeking: For some wealthy individuals, ordinary life lacks sufficient stimulation. The adrenaline of a massive bet provides an intensity that other experiences cannot match. Kerry Packer reportedly became bored with bets under $100,000.
Social and ego factors: Record bets attract attention. Being known as the person who bet $1 million on a single hand confers a certain status, particularly in gambling cultures where courage is admired. This dynamic is explored in our coverage of casino design psychology.
Why Casinos Accept Enormous Bets
Given the variance involved, why do casinos accept bets that could cost them millions? The mathematics actually favor the house, but the risk management requires careful thought.
For pure chance games like roulette, the house edge is constant regardless of bet size. A $1 million bet on red gives the casino approximately $52,630 in expected value on an American wheel. The problem is variance: the casino will either lose $1 million or win $1 million, with the expected value being a small positive number. Most casinos set maximum bet limits precisely to manage this variance.
Casinos that accept enormous bets—like Binion's Horseshoe with Bergstrom—are making a calculated decision that the expected value, multiplied across many such bets, will eventually prevail. They're also betting that a reputation for accepting any bet will attract more total action, including from gamblers who bet at lower limits.
The Modern Era: Are Mega-Bets Disappearing?
The era of celebrity mega-bettors may be waning. Several factors have combined to reduce the visibility of record-breaking wagers:
Privacy concerns: Wealthy gamblers increasingly demand anonymity. Unlike Ashley Revell, who courted publicity, today's biggest bettors prefer to remain unknown. Casinos cooperate because the alternative—exposing clients—would destroy their VIP businesses.
Anti-money laundering regulations: Financial regulators have become increasingly interested in large cash transactions at casinos. The reporting requirements and scrutiny associated with massive bets discourage some wealthy individuals from gambling at previous levels.
The Macau crackdown: China's anti-corruption campaign, combined with COVID-related travel restrictions, devastated the VIP gambling industry in Macau. The junket operators who facilitated billion-dollar betting volumes have largely collapsed, as detailed in our coverage of Macau junket operators.
Still, somewhere in the world, someone is likely preparing the next record-breaking bet. The combination of wealth, risk tolerance, and the casino industry's willingness to accommodate high rollers guarantees that the stories will continue—even if we never hear about most of them.
Lessons from Record-Breaking Wagers
What can ordinary gamblers learn from these extraordinary stories? Perhaps the most important lesson is the role of luck in outcomes. Ashley Revell's roulette win was genuinely improbable—and his entire life would have been different had the ball landed on black. No amount of courage or conviction can change the mathematics of chance.
The stories also illustrate the psychological dangers of big wins. William Lee Bergstrom's fatal pattern—win big, bet bigger, lose everything—is common among problem gamblers. Success breeds overconfidence, overconfidence leads to larger bets, and eventually mathematics catches up.
Understanding these dynamics is crucial for anyone who gambles. Tools like our Expected Value Calculator can help quantify the true cost of gambling, while resources from the National Council on Problem Gambling provide support for those who recognize warning signs in their own behavior.
The most expensive casino bets make for compelling stories precisely because they're so unusual. For most people, the wisest approach to gambling is one that treats losses as the price of entertainment—not as the foundation for ever-larger bets in pursuit of a dramatic win that probably isn't coming.
