You’ve probably seen the viral clips of a guy in a flashy Astros jersey hauling around literal suitcases of cash. People call it "degen" behavior or just plain insanity. But when we talk about the largest bet ever placed, we aren't just talking about a lucky night at the craps table. We're talking about a $10 million mathematical hedge that turned into a $75 million payday.
That’s the reality of Jim "Mattress Mack" McIngvale.
Most people think gambling is just about the rush. For Mack, it was basically an insurance policy. He runs a massive furniture empire in Houston, and he offered a promotion: buy $3,000 worth of furniture, and if the Astros win the World Series, it's all free. If the team wins, Mack owes his customers tens of millions. To cover that liability, he went to the sportsbooks.
Why the $75 Million Payout Changed Everything
In 2022, the Houston Astros took down the Philadelphia Phillies, and Mattress Mack didn't just win; he broke the legal sports betting system. He had moved $10 million across multiple books—Caesars, WynnBet, BetMGM—because no single bookie wanted to eat that much risk.
It was a logistical nightmare.
Honestly, the sheer scale of the largest bet ever placed in sports history is hard to wrap your head around. Caesars alone had to write a check for $30 million. Their CEO, Tom Reeg, even mentioned on an earnings call that this one guy's bet was a "swing factor" for their entire quarterly bottom line. That is wild. Usually, the house always wins, but Mack found the one loophole where the house was just a middleman for his furniture store's marketing budget.
The Phantom Gambler and the Suitcase of Cash
Before Mack, the legend of the "largest bet" belonged to a man named William Lee Bergstrom. Back in 1980, he walked into Binion’s Horseshoe in Vegas with two suitcases. One had $777,000 in cash. The other was empty.
He put it all on a single roll of the dice at the craps table.
He won. He filled the empty suitcase with his winnings and vanished. He came back years later and did it again with over $500,000. But the story has a dark side. In 1984, he tried to up the ante with a $1 million bet. He lost. A few months later, the "Phantom Gambler" took his own life. It’s a sobering reminder that while we celebrate the massive wins, the "all-in" mentality is a double-edged sword that cuts deep.
Casino Whales vs. Sports Bettors
There is a huge difference between a calculated sports hedge and a "whale" at a baccarat table. Take Kerry Packer, the Australian media tycoon. This guy was a force of nature. In the 1990s, he reportedly walked into the MGM Grand and won $40 million in a few days playing blackjack and baccarat.
He was betting $200,000 to $500,000 per hand.
Casinos hated him and loved him. He once tipped a dealer $1 million just because he liked the service. But Packer also had nights where he lost $20 million in a single weekend. When you’re dealing with the largest bet ever placed in a casino setting, it’s rarely about a "strategy" and more about who has the biggest bankroll to survive the swings.

The $1 Billion Video Poker Run
Then there’s Maureen O’Connor, the former mayor of San Diego. Her story is less about one giant bet and more about the staggering cumulative total. Between 2000 and 2009, she reportedly wagered over $1 billion on video poker machines.
$1 billion.
She didn't have that money, of course. She was "cycling" it—winning, losing, winning, losing—until she eventually spiraled and took money from her late husband’s foundation. It shows that "the largest bet" isn't always a single moment of glory; sometimes it’s a decade-long slow burn that destroys a reputation.
What Most People Get Wrong About High-Stakes Betting
We tend to glamorize these numbers, but for the professionals, it's rarely about the gamble. It's about "expected value" (EV).
- Mattress Mack wasn't gambling; he was hedging business risk.
- Billy Walters, arguably the greatest sports bettor ever, used a massive network of "runners" to place thousands of smaller bets that added up to millions, ensuring he didn't move the market price too much.
- Don Johnson (not the actor) took $15 million from Atlantic City casinos not by being lucky, but by negotiating specific rule changes and loss rebates that gave him a mathematical edge over the house.
If you’re looking at these records thinking you can replicate them, you’ve gotta understand the "math of the max." Most sportsbooks won't even let a regular person bet more than a few thousand dollars on a niche game. To place the largest bet ever placed, you need more than just money; you need a relationship with the house and a reason for them to take your action.
Actionable Insights for the Modern Bettor
You might not have $10 million to drop on the next World Series, but the principles used by these whales actually apply to anyone.
First, stop chasing the "one big score." The stories of people like Ashley Revell—who sold everything he owned to bet $135,300 on a single spin of roulette (he won, by the way)—are outliers. They are the 0.0001%. For every Ashley Revell, there are thousands of people who lost their shirts and were never written about.

Second, understand the hedge. If you have a parlay that is one leg away from winning $5,000, and the last game is tonight, you don't have to "let it ride." You can bet against your own parlay. This is exactly what Mattress Mack does on a much larger scale. You lock in a profit and remove the variance.
Third, know your limits. The house's biggest weapon isn't the 5% edge they have on the game; it's your emotions. The moment you start "revenge betting" to get back what you lost, you’ve already lost.
The world of high-stakes gambling is moving toward more transparency and more data. Whether it's the stock market shorts of Michael Burry or the sports hedges of furniture moguls, the "largest bets" of the future will likely be driven by algorithms and deep pockets, rather than suitcases of cash and gut feelings.
To stay ahead of the curve, focus on bankroll management. Never bet more than 1-2% of your total pool on a single event. It sounds boring compared to a $75 million payout, but it’s the only way to stay in the game long enough to actually win. If you want to dive deeper into the mechanics of how sportsbooks set their lines, your next step is to research "line movement" and "closing line value." Understanding why a number moves from -3 to -3.5 is more valuable than any "hot tip" you'll ever find.
