Mathew Bowyer
Born: c. 1974
Orange County, California
Charges: Operating an unlawful gambling business, money laundering, filing a false tax return
Sentence: 12 months and 1 day in federal prison, $1,613,280 restitution
Facility: FCI Lompoc
Status: Currently incarcerated (since October 2025)

Mathew R. Bowyer is an American illegal bookmaker who operated one of the largest unlicensed sports betting operations in Southern California.[1] His case grabbed national and international headlines because of his connection to the Shohei Ohtani gambling scandal. One of his clients was Ippei Mizuhara, the former interpreter for MLB superstar Shohei Ohtani, who stole nearly $17 million from the baseball player to cover gambling debts owed to Bowyer.[2] The case also exposed serious anti-money laundering failures at multiple Las Vegas casinos, resulting in tens of millions of dollars in regulatory fines.[3]

Background

Mathew Bowyer, approximately 50 years old, lived in San Juan Capistrano in Orange County, California. For at least five years, he ran an illegal bookmaking business focused on sports betting, breaking California laws that prohibit unlicensed gambling operations. The business operated through servers in Costa Rica and used betting websites to handle wagers.[1]

At its peak, Bowyer's operation had more than 700 active bettors as clients, including current and former professional athletes from various sports leagues.[4]

The Gambling Operation

How It Worked

Bowyer's illegal gambling business primarily used a website called AnyActionSports.com, which ran through servers in Costa Rica to avoid U.S. gambling laws. Clients would set up accounts and place bets on sporting events through the platform. Bowyer would collect losses and pay out winnings, operating entirely outside the regulated sports betting industry.[4]

The operation was substantial. Betting activity generated millions of dollars annually. He targeted high-net-worth individuals who could absorb significant gambling losses.

Meeting Ippei Mizuhara

In 2021, Bowyer's life intersected with one of the most significant sports scandals in recent memory. During a poker game in San Diego, Bowyer and an associate met Ippei Mizuhara, who was the Japanese-language interpreter and close confidant of Los Angeles Dodgers superstar Shohei Ohtani at the time.[4]

Mizuhara obsessively placed sports bets on his phone between hands during that game. Not long after, Bowyer set him up with an account on his illegal betting platform.

Connection to the Ohtani Scandal

The Scope of Mizuhara's Gambling

What started as a connection at a poker table became one of the largest sports betting scandals in American sports history. Between December 2021 and January 2024, Ippei Mizuhara placed at least 19,000 bets through Bowyer's illegal gambling operation.[5]

The scale was staggering:

  • Total winning bets: approximately $142,256,769
  • Total losing bets: approximately $182,935,206
  • Net losses: approximately $40,678,436[5]

Mizuhara stole nearly $17 million from Shohei Ohtani's bank accounts to cover these massive gambling debts without the baseball star's knowledge. Having access to Ohtani's finances as his trusted interpreter and de facto manager made this theft possible.[2]

No Evidence of Baseball Betting

Federal investigators found no evidence that Mizuhara wagered on baseball games. Prosecutors confirmed there was no evidence Shohei Ohtani was involved in or aware of Mizuhara's gambling activities either. Ohtani cooperated fully with investigators and is considered a victim in the case.[5]

Mizuhara pleaded guilty to bank fraud and filing a false tax return and was sentenced to 57 months in federal prison.[6]

Money Laundering Through Las Vegas Casinos

Casino Gambling

Bowyer laundered significant proceeds from his illegal gambling business through several Las Vegas casinos. Investigators found that Bowyer gambled away approximately $13 million at Resorts World Las Vegas alone over a nearly two-year period, most of which came from Ohtani's stolen money funneled through Mizuhara's gambling debts.[3]

Casino Compliance Failures

Bowyer's activities revealed serious anti-money laundering (AML) compliance failures at multiple Las Vegas casinos. The Nevada Gaming Control Board investigation showed that casinos had welcomed Bowyer and his associates despite knowing or having strong reason to know they were connected to illegal bookmaking operations.[3]

The regulatory consequences were substantial:

  • Resorts World Las Vegas: Fined $10.5 million by Nevada gaming regulators, the second-largest fine ever handed down by the state's gaming commission. Regulators found that "the culture within Resorts World created the perception, or the reality in certain instances, that Resorts World is an avenue to launder funds driven from illegal activity."[3]
  • MGM Resorts: Fined for AML compliance failures related to Bowyer's gambling activities.
  • Caesars Entertainment: Reached a $7.8 million settlement in November 2025 for AML violations connected to the case.[7]

The combined regulatory fines approached $27 million, making this one of the most significant casino compliance failures related to a single individual in Nevada gaming history.

Tax Fraud

Beyond the illegal gambling and money laundering charges, Bowyer faced tax fraud charges. On his 2022 federal tax return, he reported total income of just $607,897. His actual unreported income from his illegal gambling business was $4,030,938, meaning he failed to report more than $4 million in income to the IRS.[1]

Federal Charges and Plea

In August 2024, Bowyer pleaded guilty to three federal charges:

  • One count of operating an unlawful gambling business
  • One count of money laundering
  • One count of subscribing to a false tax return[1]

Sentencing

On October 2025, United States District Judge John W. Holcomb handed down this sentence:

  • 12 months and 1 day in federal prison
  • 2 years of supervised release
  • $1,613,280 in restitution[1]

Many observers found the sentence lenient given the scale of the illegal operation and its connection to the high-profile Ohtani scandal. Still, prosecutors noted Bowyer's cooperation with the investigation.

Incarceration

Bowyer began serving his sentence on October 10, 2025, at Federal Correctional Institution Lompoc, a low-security federal correctional institution located in Lompoc, California.[1]

Impact and Legacy

The Bowyer case had consequences that extended far beyond his own prosecution:

  • It resulted in the imprisonment of Ippei Mizuhara for nearly five years
  • It led to tens of millions of dollars in regulatory fines against major Las Vegas casinos
  • It prompted increased scrutiny of casino anti-money laundering practices
  • It generated international attention due to Shohei Ohtani's status as one of baseball's biggest stars[2]

The case also highlighted the ongoing challenge of illegal sports betting operations in the United States, even as legal sports gambling has expanded rapidly following the Supreme Court's 2018 decision striking down the federal ban on sports betting.

Media Coverage

Bowyer gave an interview to Rolling Stone magazine before beginning his prison sentence, offering insight into his relationship with Mizuhara and how the gambling scheme operated. In the interview, he discussed meeting Mizuhara at the poker game, setting him up with a betting account, and watching the debts accumulate over time.[4]

Sports media outlets covered the case extensively due to the Ohtani connection, and gambling industry publications also paid attention given the regulatory implications for casinos. The story also attracted significant attention in Japan, where Ohtani is a national celebrity.[2]
