Flashing lights, slot machines, blackjack, poker, and… investments?
Prediction markets, meme stocks, cryptoassets, and trading apps are on the rise, and large parts of the financial world are starting to look and feel more like a casino than a capital market.
For many younger investors (and some older ones too), gambling, prediction markets, and investing all sit in one mental bucket: places on a screen where you take a risk and hope the number goes up. The result is a gambler’s mindset, where investment risk is treated as luck rather than something that should be thoughtfully managed over time.
The way investors think about risk can have a big impact on short- and long-term outcomes, and a swipe or a tap on a phone screen can turn serious financial decision-making into something that feels like a Vegas table game.
It's all in the numbers
What once felt niche is now firmly part of the mainstream—and the numbers help show just how much this behaviour has grown.
- The American Gaming Association’s State of the States 2025 report notes that US commercial gaming revenue reached around $72 billion in 2024, marking a fourth consecutive record year.
- iGaming Ontario’s 2023 - 2024 annual report shows that legal online gambling generated about $2.2 billion in gaming revenue on roughly $63 billion in wagers in Ontario alone.
The cards are on the table: the casino mindset has become a prominent part of mainstream financial life—and it’s impacting financial futures.
Different games, different math
Risk is present in both gambling and investing, but the math behind each is very different.
In gambling, everything is designed so the house profits over time. Odds and payout tables are set in advance, and the longer a player stays at the table, the more likely that built‑in edge is to show up.
Investing works differently. By investing in a diversified portfolio of productive assets, investors own claims on future cash flows, corporate profits, rents, and interest payments. The path can be uncertain and bumpy, but the expected outcome is positive because returns are built on real economic activity—not just blind luck.
In gambling, the odds are always tilted in favour of the house. In investing, portfolio diversification, periodic rebalancing, fee awareness, and basic tax planning all help favour the investor. How?
- Spreading capital across sectors, countries, and asset classes reduces reliance on any single outcome.
- Rebalancing helps prevent yesterday’s winner from quietly becoming tomorrow’s concentrated risk.
- Lower costs and thoughtful mix of account types mean more of the gross return compounds on behalf of the investor.
This infrastructure doesn’t exist at the casino.
When markets are treated like a betting slip, that structural advantage is surrendered. Instead of behaving like the house through owning broad exposure to companies and economies, investors can drift toward more speculative, narrowly focused bets, where luck dominates, and the odds worsen the longer the game is played.
How the casino mindset impacts behaviour
The casino mindset does more than influence some speculative trades—it completely shifts how people approach money and time.
When investing is equated with gambling, holding periods tend to shorten. Portfolios become more concentrated as attention moves toward the latest story, and diversification starts looking boring. Together, this all makes it harder to build the steady compounding that long‑term goals such as retirement, home ownership, or funding education require.
Trading apps and prediction markets encourage reactions to every piece of news, making rebalancing feel wrong‑headed—why trim something that’s gone up or add to something that’s lagged? Yet this discipline is precisely what helps keep risk aligned with an investor’s original intentions, rather than drifting with market fashion. Ignoring fees and taxes because “it’s only a trade” also has a habit of quietly shrinking lifetime returns, as spreads, commissions, and tax drag all pile up over time.
Over time, this split in mindset can create two very different experiences: One group treats investing as a way to own businesses and plan around real‑world goals. The other treats it as entertainment on a phone. The first group edges closer to being the house. The latter keeps coming back to play one more game.
Be boring. Make money.
It may not sound exciting, but a clear financial plan is essential for every investor.
So what does that look like for different stages of the investment journey?
- Investors early in their savings journey: The real advantage isn’t a better macro forecast. It’s time, the ability to diversify broadly from the start, and the habit of contributing regularly to a sensible portfolio across different market environments.
- Investors mid-career or nearing retirement: Consistency becomes key. This includes rebalancing back to a chosen asset mix even when it feels uncomfortable, paying attention to fees and implementation costs, and structuring accounts in a way that reduces unnecessary tax leakage. It may be boring—but it’s what makes money.
Public equity markets also offer something that casinos never will: the ability to own a slice of the global economy, rather than betting against manufactured odds. Risk can’t be eliminated, and meaningful returns will always come with periods of discomfort. But when risk is taken thoughtfully and patiently, the expected result over time is in the investor’s favour.
Investing works best when anchored in patience, diversification, disciplined rebalancing, and attention to costs and taxes. So, the next time you feel the urge to swipe or tap to place a bet, remember this: Be Boring. Make Money.
Bet on a well‑built portfolio and a plan you can actually stick with. Don’t play in the casino—start owning it.
