Call It Investing All You Want — the House Still Wins

Bank of America Institute asked Americans whether sports betting counts as an investment. One in five said yes. Ask Gen Z, and the share roughly doubles: about two in five Gen Z adults called it a form of "nontraditional" investing — twice the rate of every other generation. That is not a harmless quirk of polling. It is a category error with real money on both sides of it, and the same arithmetic that makes it dangerous for the bettor is exactly what makes the betting operators investable.

The label doesn't change the math

Here is the line worth drawing, because the poll just blurred it. An investment is a claim on something that produces value — a slice of a business that earns cash and grows it, an asset that compounds. When you buy an index fund, you own the earnings, and over time those earnings grow and you get paid for production. A bet is the opposite: nothing is created. Money simply moves from you to whoever priced the wager — and that person has baked a fee into every ticket.

The fee is visible if you know where to look. On a coin-flip bet, a sportsbook typically asks you to risk $110 to win $100, so you need to win more than 52 of every 100 such bets just to break even. The edge inside that spread is why the Bureau's own data shows the pattern across every generation: customers got back under 75 cents for every dollar they sent in — and even Gen Z, the best performing cohort, recovered just over 80 cents and still did not break even. Recover less than a dollar and the thing is not failing to work; it is working exactly as designed.

The word "investment" is doing heavy work here. Gen Z has excellent investing instincts by almost every honest measure — they start earlier and diversify more than the generations before them. The problem is the boundary. In a Betterment survey of 1,000 investors, 52% of Gen Z said they had redirected money intended for investing toward sports bets, and roughly a quarter said betting belongs in their long-term financial plan. That is not diversification; it is feeding the house to fund the portfolio.

The cost is worse than it looks because of compounding. The stock market has averaged about 10% a year, and $10,000 left alone for 40 years grows past $450,000. A slot for that compounding to live is a real asset; a bet, no matter how confident you feel about the game, is an expected negative return against a counterparty who cannot lose in aggregate. The scarce thing a young person owns is time in the market, and this is the one error that spends it.

On the other side of the edge

Now flip the table. That same negative-expectancy math is someone else's business model.

The two companies standing between most American bettors and their money are DraftKings and FanDuel (Flutter's U.S. arm), which together hold about two-thirds of the market. Their economics do not depend on bettors winning — they depend on volume and on the hold, the share of every dollar wagered they keep. And the volume is enormous and growing. Americans legally wagered nearly $167 billion on sports in 2025, up 11% from the prior year, and state-licensed sportsbooks kept a record $16.96 billion of it — roughly a dime of every dollar, up nearly 23% from 2024.

That hold is the dividend the operator never has to ask for. It is why DraftKings, which generated about $6 billion of revenue in fiscal 2025, is guiding its adjusted-EBITDA margin up to roughly 13.5% as unsustainably heavy marketing spending scales. It is why the operator's profitability improves precisely as its users get more numerous and more frequent — and the survey's Gen Z finding is a demand signal in that direction. The demographic that most enthusiastically calls betting "investing" is also the demographic driving the activity: in July, Gen Z alone accounted for roughly half of all U.S. betting activity, and wearing the label of investment predicts more wagers and stickier engagement, not less.

So the person who reads "Gen Z calls betting an investment" purely as a consumer-behavior warning is reading only half the sentence. The other half is that the operators own both the volume and the mathematical edge. That is the asymmetry hiding inside what looks like a headline about oversharing at a dinner party.

The edge has a cost, and it is mounting

The honest objection is that the business runs on the financial weakness of its own customers, and that is a real and unresolved risk — not a detail to wave away.

The data shows the demand is coming from the least cushioned households. The median deposit balance for betting households is roughly 60% of what non-betting households hold, and lower-income households make up the largest share of bettors. One survey found 25% of sports bettors had missed a bill because of wagers and 30% had taken on debt to bet; a Federal Reserve Bank of New York study found credit-card delinquencies among sports bettors under 40 jumped 26% after legalization. A customer base that is getting thinner while it bets more is a social problem first, a regulatory problem second, and then a business problem — margin, regulation, and tax policy can all turn against the operators that sit on top of it.

That is not hypothetical. Flutter's stock fell hard over the past year, and both the operators have given back a quarter or more of their market value amid the rise of prediction-market platforms that drain handle away, and amid a live regulatory war over whether event contracts are derivatives or gambling. The CFTC is arguing for one side, state and tribal regulators for the other, and a platform like Kalshi has already shut down a sports-betting contract after the CFTC intervened. The structural edge is real; the durability of the business rests on how regulators and a worsening, debt-loaded customer base resolve it.

Here is the framework the survey really offers. There are two ways to be on the right side of this edge, and only one of them is a product you can buy: you can own the operator and collect the hold, or — more straightforwardly for most people — refuse to pay it and let your own capital compound. Calling a bet an investment does not change the arithmetic either way. The house wins on the numbers, whichever side of the ticket you choose to stand on.
