How did David Walsh make his money?
David Walsh art collector: gambling and museum
David Walsh (art collector) earned his wealth through professional gambling. According to 888casino (gambling industry analysis), he started with disciplined blackjack play and later moved into racing and pool markets. His winnings funded the construction of MONA, which opened in 2011 at a cost of AUD 171 million (Larry’s List art market intelligence).
- Walsh’s collection includes thousands of pieces, roughly 700 works of art, and extensive ancient coins (Larry’s List).
- MONA is a museum on Hobart’s Berriedale peninsula, housing Walsh’s private collection (888casino).
The implication: Walsh transformed gambling success into a major cultural institution, making his money from high-stakes wagering rather than inheritance or a salary.
David Walsh journalist: salary and book royalties
David Walsh (journalist) earns as chief sports writer at The Sunday Times — a role he has held since 2001 (Wikipedia). His income comes from his newspaper salary and royalties from books like The Russian Affair (published 2020). Unlike the art collector, his earnings are not in the billionaire range.
David Walsh entrepreneur: Netwatch
David Walsh (entrepreneur) co-founded Netwatch, a company that provides remote video monitoring and security services. The firm has grown into a global business, but its founder’s personal income is not publicly disclosed (Wikipedia).
The pattern: the three David Walsh’s built wealth through very different paths — gambling, journalism, and entrepreneurship.
Is David Walsh a billionaire?
Net worth estimates for David Walsh (art collector)
The art collector David Walsh has an estimated net worth of $1.6 billion, according to Wikipedia. This places him among the wealthiest art collectors in Australia. His fortune stems from gambling and the value of MONA’s collection, which Larry’s List valued at close to AUD 100 million.

Net worth of David Walsh entrepreneur
The entrepreneur’s net worth is also undisclosed. Netwatch’s private ownership means no public filings are available to verify his personal wealth.
What this means: only one of the three David Walshes — the Australian gambler and museum founder — has a publicly documented net worth in the billions.
What is the story of David Walsh?
David Walsh (journalist) and the Lance Armstrong investigation
David Walsh (journalist) began investigating Lance Armstrong’s suspected doping in 1999. His reporting for The Sunday Times was pivotal in the case that led to Armstrong being stripped of his Tour de France titles in 2012 (Wikipedia). Walsh also wrote The Russian Affair, a book on state-sponsored doping.
David Walsh (art collector) and MONA museum
David Walsh (art collector) founded the Museum of Old and New Art in Hobart, Tasmania, which opened in 2011. Andrew Leigh (Australian economist and politician) describes Walsh as “Australia’s most successful professional gambler” and notes that MONA is “Australia’s most successful museum.” The museum attracts international visitors and houses thousands of artworks.
David Walsh (entrepreneur) and Netwatch
David Walsh (entrepreneur) co-founded Netwatch, a security technology firm based in Ireland. Under his leadership, the company expanded into global markets, focusing on proactive video monitoring for businesses (Wikipedia). His story is less public than the other two, reflecting a more private business career.
Why this matters: each David Walsh’s story represents a different kind of success — investigative journalism, cultural patronage, and technology entrepreneurship.
Who is the richest gambler of all time?
David Walsh (art collector) as professional gambler
David Walsh is often cited among the richest gamblers in history. His net worth, built largely through gambling, is estimated at $1.6 billion. 888casino notes that he converted gambling gains into art, architecture, and festivals.
Bill Benter: another famous gambler
Bill Benter, also a professional horse-racing bettor, is widely considered the richest gambler of all time, with a net worth exceeding $1 billion. Benter’s success came from sophisticated statistical models (Wikipedia).
Comparison of gambling fortunes
- David Walsh (art collector): ~$1.6 billion from blackjack, racing, and pools.
- Bill Benter: over $1 billion from horse racing models.
The trade-off: while Walsh’s gambling fortune is impressive, Benter’s use of mathematics arguably makes him the more analytically successful gambler. Walsh, however, used his fortune to create a world-class museum.
