Overview of Phil Mickelson’s Gambling Ventures

“Gambling has been part of my life ever since I can remember. But about a decade ago is when I would say it became reckless. It’s embarrassing. I don’t like that people know. The fact is I’ve been dealing with it for some time.” — Phil Mickelson, June 2022, Sports Illustrated

The rumors of Phil’s passion for gambling, and in many cases, high-stakes gambling, became public recently. A lot came to light through the June 2022 interview with Sports Illustrated’s Bob Harig and in Alan Shipnuck’s book.

Here are some of the biggest rumors of Phil Mickelson’s gambling:

  • Hitting on a $560,000 Super Bowl winning bet in 2001
  • A $20,000 win on the Baltimore Ravens at 28-1 odds in 2000
  • Betting on or against fellow players during play on the PGA TOUR
  • Betting $200K with Tiger Woods in the charity events, The Match
  • Losing $2 million to the most successful sports bettor ever

The estimate for Phil Mickelson’s gambling losses is over $40 million between 2010 and 2014 alone.

Mickelson & The Most Famous Sports Bettors Of All-Time

Phil’s relationship with famous gambler Billy Walters eventually became the crack in the dam that would expose the depth of his gambling issues.

Walters has been called one of the best sports bettors of all time, yet he also went to prison. And he and Mickelson became fast friends.

The pair met in 2006 at a golf tournament and would gamble together for over six years. Mickelson eventually wound up owing Billy up to $2 million from sports betting, and their relationship formally ended after Billy went to prison for insider trading. 

While significant losses rarely come to light for high-stakes gamblers, it is staggering to hear of what Phil potentially lost at the height of his issues.

The estimate for Phil Mickelson’s gambling losses is over $40 million between 2010 and 2014 alone.

The Phil Mickelson Insider Trading Scandal

In 2012, Phil Mickelson was accused of receiving insider information on the stock market from gambler and bookie Billy Walters. It’s reported that he profited $931,000 from a stock trade on Dean Foods, Inc. While he was never formally charged, two of his friends (and his bookie) did face charges. 

In late May 30, 2014, The Wall Street Journal reported that the FBI and SEC were investigating Mickelson and several of his associates for insider trading. In 2016, Mickelson was named as a defendant in an SEC complaint alleging insider trading.

Mickelson denied he did anything wrong in these situations. He eventually avoided criminal charges in a parallel case brought in the Federal District Court for the Southern District of New York.

These accusations stemmed from trades in Dean Foods in 2012 in conjunction with confidential information provided by Thomas Davis, a former director of Dean Foods Company, who tipped his friend and “professional sports bettor” Billy Walters.

The SEC alleged that Walters told Mickelson non-public information about Dean Foods, and the SEC fined Mickelson the equivalent of the $931,000 profit he made from trading Dean Foods stock and interest of $105,000.

In 2017, Walters was convicted of making $40 million on Davis’s private information from 2008 to 2014 by a federal jury. It was also noted at that time that Phil Mickelson’s gambling debt to Walters once totaled around $2 million.

Phil Mickelson Betting on Golf Events

In the early 2000s, gambling was such a focal point of Mickelson’s life that it bled into his performance on the golf course and others. Naturally, when this came to light, it landed him in a fair bit of trouble.

One such case was during a playoff between Woods and Furyk in 2001. When Furyk found his ball in a bunker, Mickelson put out a $20 wager that Furyk would make the shot which Mike Weir accepted and lost. News of this bet returned to the PGA TOUR Commissioner, who spoke sternly with Mickelson, as he violated PGA TOUR rules.

Similarly, Gary McCord has revealed that he frequently bet with Mickelson while announcing. He would discretely flash his odds for each wager to Mickelson’s caddie, who would then relay the numbers to Mickelson. At the simple nod of a head, the bet was on. Once again, when the tour and CBS discovered this, they promptly stopped it.

Phil Mickelson’s Philanthropic Efforts

In 2004 Phil and his wife Amy founded the Phil and Amy Mickelson Foundation. The focus of their work has been supporting a variety of youth and family initiatives.

“Family is our number one priority. Both Amy and I benefited by being raised in our own strong, loving families, and now we’re fortunate and thankful to be in a position to help others strengthen their own family bonds.”  — Phil Mickelson on his Foundation

In 2004, Phil and Amy joined the PGA TOUR to create Birdies For the Brave, the PGA Tour’s national military outreach platform. That program encompasses various military outreach and appreciation activities conducted during PGA TOUR tournaments. It also includes a series of fundraising events hosted at the TOUR’s TPC clubs and partner courses nationwide.

Funds raised go directly to support services for military members, veterans, and their families, ranging from financial aid and rehabilitation programs to housing, counseling, educational scholarships, career development, and recruitment.

These philanthropic efforts have undoubtedly helped offset Phil Mickelson’s gambling debt and controversies. It’s important to note that these initiatives pre-date the time when many of his gambling woes came to light. Therefore, he didn’t embark on them through selfish means to save face, but rather, he genuinely wanted to give back to those less fortunate.
