10 Massive (Secret) Gambling Debts and How They Were Exposed

Gambling debt has a way of spiraling fast, turning risky bets into life-altering consequences. From athletes and executives to heirs and high-profile figures, many have fallen into the same pattern: mounting losses, desperate cover-ups, and ultimately, exposure. What starts as an attempt to win big often ends in financial ruin, legal trouble, or public scandal.

This slideshow looks at some of the most extreme gambling debt cases and the lengths people went to avoid paying what they owed. We break down how much was lost, where it happened, and the tactics used to hide the damage, along with the consequences that followed. These stories offer a revealing look at how quickly things can unravel when the stakes get too high.

When debts spiral out of control, even the wealthy and powerful make reckless choices. Fraud, deception, and even desperate escapes ultimately bring disastrous consequences. By reviewing these different cases, readers can gain insight into how addiction drives decision-making and why legal systems intervene so forcefully. Covering these examples matters because they illustrate the universal dangers of financial overreach, the thin line between thrill-seeking and ruin, and how accountability eventually catches up with everyone.

Shohei Ohtani is considered a generational talent in the MLB, and as such he commands the highest salary in the league making a whopping $70 million per year. While Ohtani is making millions, his longtime Japanese interpreter and aide, Ippei Mizuhara, sought to cash in too but in a more nefarious way. Mizuhara started racking up large gambling debts around 2021 with an illegal bookmaker. To cover these debts, Mizuhara misappropriated funds from Ohtani's bank account without his knowledge, using his login credentials and changing account security/email/phone so he could intercept verification calls. He would even go as far as to impersonate OHtani to authorize wire transfers, and using the money for gambling losses and personal expenses. ////////////////// Accordingly, Mizuhara was fired in March 2024 after the allegations became public. He ultimately pled guilty to bank fraud and filing a false tax return. Mizuhara was sentenced to 57 months in prison and ordered to pay roughly $17 million in restitution. It's worth noting that Ohtani has publicly maintained that he did not place any bets or know about the misappropriation until all had come to light.

Phil Ivey, a world-renowned poker player with a number of World Series bracelets, exploited a little known technique called "edge-sorting" with his partner Kelly Sun in a series of high-stakes baccarat games. While initially the casinos in question agreed to Ivey's terms of play and accommodated them (including the decks of cards to be used), the casinos later learned that they had been duped. Edge-sorting is a method of determining face-down cards based on the markings on the backs of these cards. Slight imperfections in these markings based on how the cards were cut at the factory tell the player the full story. Ivey took down about $12 million from Crockfords Casino and $9.6 million from Borgata. However, the casinos turned to the courts in the US and UK which ultimately ruled against Ivey but settlements were made outside of the courts so the picture is not entirely clear.

Yew Choy Wong made international headlines after a truly epic losing streak at the Crown Casino in Melbourne. Over a few days in 2018, he lost about $43 million (Australian dollars) playing baccarat.

As a result, Wong refused to pay the massive line of credit that was extended to him, citing this error. The case turned into a legal battle, with Crown Casino taking the case all the way up to Singapore's High Court. In 2020, the court ruled against Wong, ordering him to pay the debt plus interest.
