While Foley was living in
Jacksonville, Florida, he explored buying the
National Football League's
Jacksonville Jaguars, before the team was acquired by
Shahid Khan. In late 2006, Foley became the majority shareholder of Winter Sports, Inc. (WSI), the operator of
Whitefish Mountain Resort, in
Whitefish, Montana. Foley's takeover of WSI occurred through a series of two
reverse stock splits that took WSI from a publicly traded company, with many shareholders living in the local
Flathead Valley, to a private
S corp. Foley was able to purchase 27% of the outstanding WSI shares in the early 2000s from Richard A. Dasen, a local shareholder who went to prison for 14 prostitution-related crimes. In June 2016, Foley and Black Knight Sports & Entertainment was awarded a
National Hockey League expansion franchise that became the
Vegas Golden Knights. The Golden Knights began play in the
2017–18 season at the new
T-Mobile Arena, and also acquired a minority ownership of the facility. Foley pledged to win a
Stanley Cup in six seasons, and the Golden Knights made good on that promise in 2023. In 2020, Black Knight Sports & Entertainment purchased an
American Hockey League franchise to act as a development team for the Golden Knights, relocating the
San Antonio Rampage to become the
Henderson Silver Knights. The Silver Knights played out of the
Orleans Arena until the
Dollar Loan Center, which is operated by Black Knight Sports & Entertainment, was completed in 2022. In 2021, Foley announced Black Knight Sports & Entertainment had purchased an expansion team in the
Indoor Football League to begin play in 2022 at the Dollar Loan Center in
Henderson, Nevada. On August 23, 2021, the team unveiled their name and logo as the
Vegas Knight Hawks. On December 13, 2022, a group of investors led by Foley completed a deal to purchase English
football club
AFC Bournemouth, with Foley assuming the role of chairman. Ahead of the deal, he was present at one of Bournemouth's
Premier League matches against
Leicester City, with the
Cherries winning 2–1. On January 13, 2023, Foley acquired a significant minority stake in French football club
Lorient, creating a partnership with Bournemouth. On October 11, 2023, the
Australian Professional Leagues (APL) announced Foley as the preferred bidder to be the owner of a new
A-Leagues expansion club, based in
Auckland, New Zealand. The APL officially confirmed the new team would be awarded a licence under Foley's ownership on November 21, with the
Auckland FC men's team being introduced for the
2024–25 A-League Men season and the women's team competing from 2025–26 onwards. At an
AGM held in February 2024, Black Knight ratified a deal to become a significant minority shareholder in Scottish football club
Hibernian. Black Knight acquired 25% of Hibs for a £6 million investment but the stake was sold to the majority shareholders in November 2025, with "philosophical differences" cited for the partnership breaking down. As of April 2026, Bill Foley was reported to be in advanced negotiations to acquire
Exeter Chiefs. ==Personal life==
