Fame and fortune do not guarantee discipline at the tables. Some of the wealthiest names in American sports and entertainment have lost millions gambling, and a few have won just as spectacularly. If you want to experience the same games these high rollers play, a real money online casino with high stakes tables puts blackjack, poker, and roulette within reach for any player.
The stories below are not cautionary tales. They are portraits of people for whom high-stakes gambling was an extension of the same competitive drive that built their fortunes. The numbers are real, and in most cases, documented in court records, biographies, and on-camera interviews.
Net Worth: $3.8 billion (Forbes, 2025)
No list of celebrity gamblers starts anywhere else. Jordan's gambling habits were investigated by the NBA twice during the 1990s, and the paper trail is extensive. In 1992, he testified in federal court about a $57,000 check written to convicted drug dealer James "Slim" Bouler, which Jordan admitted was a gambling debt. Businessman Richard Esquinas documented in his 1993 book that Jordan ran up a golf debt of $1.252 million, doubling down repeatedly after each loss. Jordan ultimately settled for around $300,000.
The casino losses matched the golf losses in scale. In 2007, he reportedly lost $5 million in a single craps session in Las Vegas while NFL cornerback Adam Jones won $1 million at the same table. Former teammate Jay Williams described Jordan betting $20,000 on rock, paper, scissors and $300,000 on a single golf putt against Charles Barkley.
Jordan told Ed Bradley on 60 Minutes: "I don't have a gambling problem, I have a competitiveness problem." Whether that distinction holds up is a matter of perspective.
Net Worth: $1.3 billion (Forbes, 2025)
Woods holds a $1 million betting limit at the MGM Grand in Las Vegas. He regularly played $25,000 per hand in blackjack, and estimates of his lifetime gambling losses run as high as $58.5 million over a seven-year period according to data compiled by CasinoSites.me.uk.
For a man who earned approximately $1.8 billion across his golf career through tournament wins and endorsements, the casino losses represent a fraction of his net worth. The MGM limit suggests the casino viewed him as a whale worth accommodating.
Net Worth: $150 million
Affleck's gambling story goes in a different direction from Jordan and Woods. Rather than losing big, he won big, and got banned for it. He was removed from the Hard Rock Casino in Las Vegas after the house concluded he was counting cards at the blackjack table. Card counting is not illegal, but casinos reserve the right to refuse service to anyone they deem a threat to their edge.
Affleck confirmed in an interview with Details magazine that he had worked hard to improve his blackjack game. The Hard Rock ban was the consequence of doing that too well. He also lost $400,000 in a single poker session, reportedly to former Universal Studios president Ron Meyer in a private game, so his gambling record includes both ends of the spectrum.
Net Worth: $90 million (Celebrity Net Worth, 2025)
Barkley has been more open about his gambling losses than almost any public figure in the US. He has admitted to losing between $10 million and $30 million through casino gambling across his career, including $2.5 million lost in a single six-hour blackjack session. His preferred game was blackjack, and he has described losing $1 million in a single day on more than 20 separate occasions.
Despite the scale of the losses, Barkley has consistently said he has no regrets. He has since pulled back on high-stakes gambling, and his total self-disclosed losses make him one of the most candid celebrity gamblers in the US.
Net Worth: $500 million
The UFC president is one of the most visible high rollers in Las Vegas, partly because he talks about his wins publicly and often. White won $3.2 million at a Las Vegas casino blackjack table in a single session, a win significant enough that the casino blacklisted him afterward. He has also disclosed a $3 million loss, one he admitted he initially thought was only $80,000 before the final count came in.
White has been open about being banned from at least one Las Vegas venue for winning too much at blackjack, which puts him in the same category as Affleck as a player the house would rather not seat.
Net Worth: $400 million
Mickelson won $440,000 on a single Super Bowl bet during the 2000-2001 NFL season, wagering $20,000 at 22-1 odds on the Baltimore Ravens before the season began. That win became public, but it was the smaller end of his gambling activity. Professional sports bettor Billy Walters stated in his book "Gambler: Secrets from a Life of Risk" that Mickelson's total career gambling wagers reached as high as $1 billion.
Mickelson also became embroiled in a federal insider trading investigation linked to his relationship with Walters, in which he was named as a relief defendant and ultimately paid back $1 million in profits and interest. His gambling and his associations with professional bettors brought scrutiny that went well beyond the tables.
Net Worth: $400 million (Celebrity Net Worth, 2025)
Mayweather's gambling is an extension of his public persona. He regularly posts sports betting slips on social media showing six and seven-figure wagers. He once disclosed a $400,000 loss on a single sports bet, and his documented single-bet wagers have reached $1 million on multiple occasions.
His preferred gambling activity is sports betting rather than casino table games. Mayweather's career boxing earnings surpassed $1.1 billion, which gives him the financial cushion to absorb losses that would be catastrophic for almost anyone else.
Net Worth: $75 million
Maguire was a regular participant in underground high-stakes poker games in Hollywood, games later documented in Molly Bloom's memoir "Molly's Game," which was subsequently adapted into a film. The games involved millions of dollars and a roster of celebrities and businessmen willing to play at significant stakes.
Maguire was eventually sued as part of the fallout from those games, and reached an out-of-court settlement of $80,000 in 2011. His participation in private games rather than public casinos kept most of the details out of public records until Bloom's account brought them to light.
Net Worth: $10 million
Sheen's gambling habit ran alongside his other well-documented personal struggles. His ex-wife Denise Richards alleged in divorce proceedings that he was wagering $200,000 per week on sports. His reported losses over a three-month period reached $2.5 million. Unlike others on this list, Sheen's net worth contracted significantly over time, and gambling losses were part of a broader pattern of financial instability during his peak earning years on Two and a Half Men.
Net Worth: Negative (filed for bankruptcy)
Iverson earned approximately $154 million during his NBA career. By his early 40s, he had almost nothing left. Gambling was one of several factors in that decline. He was banned from multiple casinos for disruptive behavior and reportedly lost large sums at casino tables throughout his career. A trust set up by Reebok worth $32 million was structured to pay out when he turned 55, designed specifically to protect him from spending it before then.
His case is the starkest on this list because the disparity between career earnings and end result is so extreme.
The common thread across this list is not wealth. It is competitive. Jordan said it directly, and the pattern holds across almost every name here. These are people who built careers on refusing to lose, and that same refusal followed them to the casino floor. The results ranged from profitable to catastrophic depending on how much financial cushion sat beneath the bets.
