- Wealthsimple recently launched "Predict," becoming the second Canadian dealer after Interactive Brokers to offer prediction market contracts, with Canadian regulators currently restricting brokers to economy- and climate-based contracts and excluding "sexier" miscellaneous topics.
- Charles Martineau and Marius Zoican argue prediction markets are a zero-sum game where, after spreads and fees, the average investor loses money — citing a study finding the top 1% of Polymarket accounts capture about 77% of all profits.
- A Betterment study found 26% of Gen Z investors already include sports betting in their financial strategy, and the authors warn legitimizing such bets on brokerage apps will make the problem worse.
- The authors contrast prediction markets with low-fee index funds, noting that redirecting $100/month from a diversified ETF (which captures the market's long-run average annual return of 7-8%) into event contracts quietly surrenders long-term compounding.
- Prediction markets have two legitimate uses, the authors say: hedging real business risk (e.g., an ice cream shop owner buying a contract that pays out if summer is unusually cold) and sophisticated traders with modeling skills to spot mispriced contracts.
- The authors call on Canadian regulators to "stay the course" on current restrictions and urge governments and school boards to begin financial literacy education in high school before a generation raised on social media parlays mistakes prediction markets for a retirement plan.
Why it matters: With Wealthsimple's Predict launch bringing event-contract trading to mainstream Canadian retail investors, restricting product scope to economy- and climate-based derivatives prevents a generation already exposed to parlay culture (26% of Gen Z, per Betterment) from confusing zero-sum gambling for wealth-building — every dollar diverted from compounding into prediction markets is lost retirement savings the investor will not recover.
