Fifty-two percent of Gen Z investors surveyed said they've diverted money earmarked for investing into sports betting apps instead, according to CNBC's reporting on new survey data — and the gap between what that money could become and what it actually becomes is the entire story.
This matters to anyone between 25 and 45 trying to figure out investing money for beginners because the two activities now live on the same phone, sometimes in the same tapping motion. A DraftKings notification and a Fidelity dividend alert compete for the same thumb. The CNBC piece frames this as a generational shift in where discretionary dollars go; the more useful frame is what each dollar is mathematically worth depending on which app it lands in.
What CNBC's Survey Actually Found
The reported figure is specific: 52% of Gen Z investors say they have redirected money originally intended for investing toward sports betting. This is self-reported behavior from people who already identify as investors — not non-investors dabbling in DraftKings, but people with brokerage or retirement accounts choosing, in some months, to fund a parlay instead of a Roth contribution.
That distinction matters for who gains and who loses. Sportsbooks gain — DraftKings and FanDuel combined took in over $11 billion in gross gaming revenue in 2023 per state gaming commission filings compiled by the American Gaming Association, revenue that only exists because bettors lose more than they win in aggregate. Gen Z bettors lose, structurally, because sports betting is a negative-expected-value activity by design. The house edge is not a rumor — it's built into the odds before the game starts.
Brokerages and fund companies lose too, in a smaller but compounding way: every dollar that goes to a sportsbook instead of a low-cost index fund is a dollar that stops earning the market's historical long-run return, and stops compounding for however many decades are left until retirement.
Expected Value Is the Whole Argument, So Start There
Expected value (EV) is the average outcome of a bet or investment if you repeated it thousands of times. A -110 point spread bet — the standard "juice" on most sides and totals — requires you to risk $110 to win $100. Break-even against that vig requires winning 52.4% of your bets, not 50%.
Professional sports bettors, studied over large samples by outlets like Sports Insights and academic researchers at the University of Nevada Las Vegas, win against the spread roughly 53-55% of the time in their best years. Casual bettors, the CNBC-surveyed cohort almost certainly among them, tend to hover near 45-48%. At 47%, betting $100 a week for a year on -110 spreads produces an expected loss of roughly $520 — not a catastrophe on its own, but a negative-EV activity with no exceptions built in.
Compare that to the S&P 500's expected value. The index has returned an annualized average of about 10.2% since 1957, including multiple crashes, per S&P Dow Jones Indices historical data. That's not a guarantee for any single year — 2022 alone saw a decline of 19.4% — but the expected value over any 10-plus year holding period has been positive in every rolling decade on record since the 1950s.

The Compounding Math Nobody Shows You
Here's the side-by-side that the CNBC piece gestures at but doesn't run the numbers on. Take $200 a month — a plausible amount for a 26-year-old redirecting "extra" cash — and split the comparison over a 30-year horizon.
Scenario A: $200/month into an S&P 500 index fund, 30 years, 10% average annual return. Using standard compound growth math, that becomes approximately $452,000. Total contributed: $72,000. Growth from compounding: roughly $380,000.
Scenario B: $200/month wagered on sports bets at a -3% average expected return (a realistic blended house edge across spreads, parlays, and props). Over 30 years, you don't just fail to grow the money — you lose roughly $2,160 a year in expectation, compounding negatively as habit and stakes grow with income. Zero dollars available for retirement from this stream; often negative net worth contribution.
The gap isn't "betting grows slower than investing." Betting has negative expected value. Investing has positive expected value. These aren't two flavors of risk-taking — they're mathematically opposite operations, and the CNBC survey shows over half of young investors treating them as interchangeable line items in a monthly budget.
The Strongest Counterargument — and Where It Breaks
The fairest pushback: sports betting, done at small stakes, functions as entertainment spending, not investing, and comparing $20 parlays to retirement accounts is a category error — nobody compares a movie ticket to an index fund either.
That argument holds if the money comes from an entertainment budget. It stops holding the moment the CNBC-reported behavior kicks in: money redirected from investing money specifically. The survey isn't describing people who budget $50 a month for fun and separately max out a Roth IRA. It's describing investors who are pulling from the investing bucket itself, which means the opportunity cost is not forfeited concert tickets — it's forfeited compounding, at the exact age (early-to-mid 20s) when time in the market matters most because compounding math rewards early dollars disproportionately.
