  • Waterhouse VC June update: The striking similarities between betting and investing

Each month, Australian bookmaking legend Tom Waterhouse publishes a newsletter from Waterhouse VC, his gaming and wagering-focused venture capital fund.

Since inception in August 2019, the fund has achieved a gross total return of 1,863% through to 31 May 2023.

In collaboration with iGaming NEXT, the June edition of Waterhouse VC takes a deep dive into some of the world’s most successful investors and how their strategies align with professional betting behaviour.


Convergence of betting and investing

“The market is a racetrack too. But I was not developing elaborate theories in those days. I was just a little kid.”
Warren Buffet (Neckar Substack)

World-renowned investor Warren Buffett (chairman and CEO of Berkshire Hathaway), and numerous other famous investors were initially influenced by betting and bookmaking (particularly horse racing) before transitioning to financial markets.

The new wave of professional bettors are now finding success in financial markets as well, with significant cross-over in the statistical analysis and thought processes applied across the two domains.

For example, one prominent framework utilised by both investment firms and professional betting syndicates is the Kelly Criterion. Furthermore, in both betting and investing, the impact of decision-making biases and human psychology is critically important.

Warren Buffet

“You could get old racing forms… I would go through them using my handicapping techniques to handicap one day and see the next day how it worked out. I ran tests of my handicapping ability day after day.”

One may expect these to be the words of a professional bettor but they are in fact from Buffett.

Few people know that much of Buffett’s formative years were significantly influenced by horse racing.

He fervently assessed the Daily Racing Form and having figured out the probability of each horse winning a race, he even did some of his own bookmaking at the Preakness Stakes in Baltimore.

Through betting, Buffett learnt several important investing lessons, including:

“You’re not supposed to be every race” (Maiden King) – When applied to investing, this could be interpreted as there being no need to always actively invest and that it is sometimes best to do nothing.

“You don’t have to make it back the way you lost it” (Maiden King) – When applied to investing, this could be interpreted as the need to pivot investment strategies according to market conditions.

Jeff Yass

“If you’re the sixth-best poker player in the world and you play with the five best players, you’re going to lose… If your skills are only average, but you play against weak opponents, you’re going to win.”

Jeff Yass (co-founder of trading firm Susquehanna International Group) said the above when asked to describe Susquehanna’s trading strategy.

In 1985, Yass and a couple of friends bet at a track outside Chicago using analysis from a Compaq computer.

With the assistance of a statistician who had worked for NASA on the moon landing, they bet $160,000 across tens of thousands of wagers to get the exact order of seven horses in three races, ultimately winning $760,000, which was then the largest win in American racing history.

The win was never honoured, although Yass went on to make $28.5bn through Susquehanna according to Forbes.

Similarly to Susquehanna, the world’s largest betting syndicates have turned their attention to financial markets, trading equities, FX and derivatives.

For example, one of the world’s largest betting syndicates is now trading $40bn a week on FX.

On the flip side, prominent international investment firms like Susquehanna are also applying their expertise to professional betting.

In 2017, Susquehanna launched Nellie Analytics, based in Dublin, with a specific focus on sports betting.

In 2022, Susquehanna acquired a 12.8% equity stake in PointsBet, creating an opportunity for Nellie Analytics to explore a partnership in delivering sports analytics and quantitative modelling services to PointsBet.

Mohnish Pabrai

“Investing is just like gambling. It’s all about the odds. Looking out for mispriced betting opportunities and betting heavily when the odds are overwhelmingly in your favour is the ticket to wealth.”

Mohnish Pabrai (Founder of Pabrai Funds) is a fervent follower of Warren Buffett and Charlie Munger.

He published a thorough framework for value investing, ‘The Dhandho Investor’ (Dhandho is a Gujarati word translating to “endeavours that create wealth”).

There are numerous key ideas explained through betting analogies in Pabrai’s book. For example, he believes that the best way to increase returns and reduce risk is by making “few bets, big bets, (and) infrequent bets”.

He often relates betting analogies to the Kelly Criterion, which is regularly applied to both professional betting and investing.

Kelly Criterion

The Kelly Criterion was originally developed by John Kelly in 1956 to assess long-distance telephone signal noise.

It now assists investors and bettors in determining the optimal diversification of a portfolio/bankroll by calculating the proportion of their money that they should allocate to every individual investment or bet.

This proportion is the ‘K%’ in the above formula. For example, in investing, if the K% is 0.125, then a portfolio should be 12.5% invested in each stock in the portfolio, effectively telling the investor how many positions to take.

Of course, if you have a negative winning probability, ‘W’, there is no optimal Kelly percentage.

As shown below, position sizing is incredibly important in both betting and investing.

If you have a bet with a 51% probability of winning and invest 5% of your money/bankroll each time, you will achieve a very different outcome to if you invest 10%.

Minor changes to the percentage invested will ultimately make the difference between success and ‘Gambler’s Ruin’.

The Kelly Criterion is the solution to gambler’s ruin, whereby bets/investments are determined as a proportion of bankroll rather than as fixed dollar amounts, such that a person bets/invests less as their bankroll falls and bets/invests more as their bankroll rises.

The Kelly Criterion has been used by some of the world’s most famous investors, including Warren Buffett and Mohnish Pabrai.

Bill Miller outperformed the market for 15 years at Legg Mason and has been a vocal proponent of Kelly. Ed Thorp, who returned 20% per annum for 30 years, said of the Kelly Criterion: “Success leaves clues.”

Thorp also pointed out that Warren Buffett’s investing is consistent with the Kelly Criterion: “He (Buffett) and his associate Charlie Munger, when managing $200m, put most of it into just five or so positions.

“Sometimes he was willing to bet 75% of his fortune on a single investment. Investing heavily in extremely favourable situations is characteristic of a Kelly bettor.”

Betting on tennis betting

As mentioned in our April newsletter, on 1 July, Waterhouse VC will make an investment in Tom Dry’s professional betting syndicate.

With a little help from the Kelly Criterion, Tom’s operational metrics are very impressive. Tom has developed a unique specialisation in tennis, which is much easier to leverage than multiple sports.

We believe that his edge in tennis betting would be difficult to replicate due to the quantity of proprietary historical data he possesses and the factors that he applies to his model.

Charlie Munger takes a swipe at crypto

Charlie Munger, the vice chairman of Berkshire Hathaway and Warren Buffett’s trusty sidekick, took a shot at the world of cryptocurrencies in a recent Wall Street Journal op-ed, calling for a ban on all things digital and decentralised.

The 99-year-old billionaire compared the crypto industry to a wild and woolly carnival ride, with little regulation and a lot of speculation.

He compared it to mining, where salesmanship is often key to convincing investors to finance digging for precious metals that may not exist.

He called crypto a “gambling contract with a nearly 100% edge for the house,” and suggested the US take a cue from China and put a stop to the madness.

Munger has never been a fan of the crypto world and has been vocal about his dislike for it in the past.

He has compared it to rat poison, a venereal disease, and even an open sewer.

He once stated that he wouldn’t want a crypto executive to marry into his family.

It seems like Munger and crypto are just not meant to be.

Will Chau’s downfall bring Macau to its knees?

Two weeks ago, we mentioned in Hot Copy that gambling promoter Alvin Chau was sentenced to 18 years in the slammer in Macau for charges including illegal gambling, fraud, and involvement in organised crime.

The court ruled in favour of the prosecutors on most charges, but acquitted Chau of money laundering.

The Financial Times argued this week that Chau’s downfall augurs change for Macau’s gambling industry.

“[With the trial] you have a portrait of how Macau gaming actually worked . . . Macau has always been a washing machine” but the case exposes the extent of it, the FT quoted Jorge Menezes, a Macau-based lawyer.

Chau’s illegal empire was found to have had a turnover of $105bn between March 2013 and March 2021.

According to the article, the size of Chau’s “business” reflects the fact that Chinese elite have typically used junkets to channel vast amounts of money out of the country, which enforces strict capital controls.

Moreover, casino executives described the estimate of Chau’s illegal gambling turnover outlined in the judgment as “conservative” and said Chau’s ability to attract the mainland elite to Macau was unmatched in the industry. “You could not avoid dealing with him,” one said.

Chau’s downfall — driven by Beijing’s determination to crush the escape of elite capital through Macau — is set to change the gambling business in the territory, as it would be a challenge to replace the loss of earnings from elite high rollers with mass market or non-gaming revenue.

Show your cards on player safety

The Times reported that British-based gambling companies operating in the US have been asked to let outside experts peek at their safeguards for vulnerable players after receiving criticism for a lack of transparency.

FanDuel, owned by Flutter Entertainment, BetMGM, part-owned by Entain, and DraftKings, are among the companies being questioned about their protection measures for online casino players.

The US National Council on Problem Gambling is curious why these companies have not committed to a third-party assessment and is asking the question: “What are they hiding?”

With digital casino games like poker now available in seven US states, the National Council has evaluated each state’s regulations and found four states – Delaware, Michigan, Nevada and West Virginia – falling short of the minimum standards advised by the council.

The National Council wants iGaming operators to show they meet strict standards, such as those adopted by New Jersey, in all states.

FanDuel, DraftKings, and BetMGM were quick to assure that they adhere to all customer protection and responsible gaming standards in each market they operate in.

But the National Council isn’t convinced: “If they are doing it, it would be very easy to be able to show people,” Keith Whyte, executive director of the industry-funded council, said. “But they don’t,” he added.
