- Mathew Bowyer, a convicted illegal bookmaker, publicly shared his experiences following his release from a California federal facility, having served seven months out of a twelve-month sentence.
- Reflecting on his extensive illegal activities and his imprisonment, Bowyer also discussed his inclusion in Nevada’s renowned “Black Book,” which bars him from entering casinos in the state.
- Bowyer’s extensive betting operation led to significant regulatory actions, resulting in nearly $27 million in fines against casinos on the Las Vegas Strip.
Illegal bookmaker Mathew Bowyer has spoken out for the first time since his imprisonment, expressing regret over certain decisions that culminated in a one-year federal sentence.
At 51, Bowyer was sentenced in August 2025 to a year and a day after pleading guilty to tax evasion and operating an illegal sports betting venture. He was released after completing seven months at the Federal Correctional Institution in Lompoc, California.
Bowyer’s illicit gambling network catered to approximately 1,200 clients, including Ippei Mizuhara, the former interpreter for L.A. Dodgers superstar Shohei Ohtani. The scandal surrounding Mizuhara’s alleged misappropriation of $17 million from Ohtani to pay off his debts to Bowyer was pivotal in Bowyer’s eventual arrest.
Mizuhara is currently serving a 57-month federal sentence in Pennsylvania, while Bowyer has not faced charges related to that theft.
Partial Regrets
“I regret some of the poor decisions I made,” Bowyer stated in an interview with KNBC‑TV/Los Angeles from his residence in San Juan Capistrano, California, “but I don’t regret it because it shaped who I am today.”
Bowyer shared with KNBC that he has turned to writing. He published a book, Recalibrate, detailing his experiences before heading to prison and is currently penning a sequel about navigating life post-release.
During the peak of his operation, Bowyer reported earnings of approximately $1 million monthly. The stark transition from that lifestyle to prison life was shocking.
“Going from having butlers, private jets, and Rolls-Royces to eating what I can only describe as dog food was quite the adjustment,” Bowyer remarked.
Growing Repercussions
As part of his plea deal, Bowyer faces a two-year ban from gambling. He also received an unexpected visit from Nevada gaming officials during his time in prison, who informed him of his addition to the notorious “Black Book” of individuals prohibited from entering casinos in Nevada.
“They notified me that I’m banned from all gambling establishments in Nevada for life,” Bowyer revealed to KNBC.
Alongside the gambling restrictions, Bowyer must attend weekly gambling addiction meetings. He also owes nearly $9 million to the IRS in back taxes, including penalties and interest.
Significant Strip Fallout
Bowyer’s actions tarnished not just his reputation but also that of the Las Vegas Strip.
Regulators accused three major casino operators of turning a blind eye to Bowyer’s activities, allowing him to gamble millions despite questionable funds from 2017 to 2024. This exposed a pattern of negligence within the Strip’s casinos, prioritizing profits over regulatory compliance.
In 2025, Bowyer’s activities were referenced in disciplinary measures leading to substantial fines:
- $10.5 million against Resorts World (the second-largest fine in Vegas history)
- $8.5 million against MGM Resorts
- $7.8 million against Caesars Entertainment.
The affected companies resolved the allegations without admitting any wrongdoing.
