Teens and Online Gambling: Why the House Always Wins
More than a third of boys ages 11 to 17 gambled in the past year, often on a phone, through a game or after seeing it on social media. Yet every bet is built so the house comes out ahead over time. This lesson helps families understand the odds, the hooks, and the real costs, and talk about them together.
What your family will learn
By the end, you'll be able to…
- Describe how common gambling is among teens, and where they find it.
- Explain why teen brains are especially vulnerable.
- Spot the ways social media, games and ads pull teens toward betting.
- Calculate the house edge and explain why the house always wins over time.
- Name the real costs of gambling problems and where to get help.
Words to know
- House edge: the share of each bet the gambling company expects to keep over time.
- Expected value: what a bet is worth on average once you account for the odds.
- Parlay: one bet that links several outcomes; all must win to get paid.
- Loot box: a paid mystery prize in a video game.
- Social or sweepstakes casino: a casino-style app using virtual coins that can lead to real-money play.
- Chasing losses: betting more to win back what you've lost.
How many teens are gambling?
Gambling has gone from something teens had to seek out to something that finds them on their phones. In a 2026 national survey of more than 1,000 boys ages 11 to 17, 36% had gambled in the past year, including about a third of 11-year-olds and nearly half of 17-year-olds.
| What boys 11–17 did in the past year | Share of boys |
|---|---|
| Gambling-like systems inside video games (spending money for a chance at prizes) | Nearly 1 in 4 |
| Sports betting | Nearly 1 in 8 |
| Traditional gambling, such as card games for money | Nearly 1 in 8 |
| Gambled with a family member | 1 in 3 |

Most adults started young, too
It's growing with each generation: 33% of adults ages 21 to 44 bet on sports before 21, compared with 11% of adults 55 and older. Since a 2018 Supreme Court ruling, legal sports betting spread from one state to 38 by 2024, and Americans bet nearly $167 billion with legal sportsbooks in 2025. In Ohio, sports betting is legal at 21.
The parent blind spot
Mott Poll, 2024
Common Sense Media, 2026
The two surveys measure different things, but the gap is a warning. In the same parent poll, 1 in 6 parents said they probably wouldn't know if their teen was betting online, only 1 in 4 had talked with their teen about it, and two-thirds said their teen has a bank account, debit card or credit card in their own name.
Why teens are especially vulnerable
Teens aren't just younger gamblers. Their brains are still building the brakes that help adults weigh risk, which makes the same bet riskier for them.
A brain still under construction
The prefrontal cortex, the brain's planning and judgment center, isn't fully developed until the mid-20s. Gambling lights up the brain's reward system much like drugs and alcohol do, and teens feel those highs more strongly.
Starting early raises the risk
Children introduced to "harmless" betting by age 12 are four times more likely to develop gambling problems later, according to Massachusetts public health officials. Gambling disorders can begin around age 10.
Feeling in control
Teens tend to overestimate how much skill controls the outcome. Knowing a lot about sports feels like an edge, but it doesn't beat the built-in house edge.
Friends matter most
Among boys whose friends gamble, more than 8 in 10 gamble too, compared with fewer than 2 in 10 whose friends don't. Some teens with accounts even act as bookies for classmates.
Escape from stress
Betting can become a way to cope with stress, boredom or difficult feelings, and over time teens may need bigger bets to feel the same rush.
Boys face higher risk
Research on people ages 10 to 25 links online gambling with a higher risk of gambling problems, especially for boys and young men.
How gambling reaches teens on their phones
Most teens don't go looking for a casino. Gambling comes to them through the apps, games and videos they already use, and age checks are easy to get around.
| Where it shows up | What it looks like | Why it matters |
|---|---|---|
| Social media & YouTube | Betting ads, promo codes, and gambling content served up by the algorithm | 6 in 10 boys see gambling ads there; nearly half of boys who gamble see content promoting it, mostly recommended to them |
| Streamers & influencers | Popular creators gambling live, celebrities and athletes in betting ads | Streamers often play with the casino's money, so their big wins aren't real risks; links in chats can lead to offshore casinos |
| Video games | Loot boxes, spins, and betting with "skins" (in-game items worth real money) | The most common place boys meet gambling-like systems; kids as young as 6 or 7 have spent large sums |
| Social & sweepstakes casinos | Casino-style and sportsbook apps that use virtual coins | They feel like games, which blurs the line between playing for fun and playing for money |
| Sports broadcasts & apps | Betting odds on screen, sponsorships, bets on nearly every pitch or play | Makes betting feel like a normal part of being a fan |
| Workarounds | A parent's logged-in account, an older friend, a fake ID, a VPN, or an offshore or crypto site | Legal sites require ages 18 or 21, but these routes skip the safeguards |
| Prediction markets | Apps for trading on the outcomes of events | Newer and lightly regulated; Americans are most likely to describe them as gambling |
The next time a betting ad comes on, pause it and ask: What is this ad promising? Who is it trying to reach? What doesn't it show? Ads emphasize big wins and excitement and rarely show the losses.
The real odds: why the house always wins
Every bet is priced so the gambling company keeps a slice, called the house edge. Any single bet can win, but the more you bet, the closer your results get to that built-in loss. In 2025, U.S. sportsbooks kept about $16.9 billion of the $167 billion people bet, about $10 of every $100.
On a standard sports bet, you risk $110 to win $100. If the game is a true coin flip: (0.5 × $100) − (0.5 × $110) = −$5 per bet. You'd have to win 52.4% of your bets just to break even.
| The bet | Your chance | House keeps, per $100 bet |
|---|---|---|
| Single sports bet at standard odds (−110) | About 50/50, but you must win 52.4% to break even | $4.55 |
| American roulette, betting on red | 18 in 38 (47.4%) | $5.26 |
| 3-team parlay (each team a coin flip) | 1 in 8 | $13.03 |
| 5-team parlay (each team a coin flip) | 1 in 32 | $20.75 |
| Powerball ($2 ticket) | Jackpot: 1 in 292.2 million. Any prize: 1 in 24.9 | Varies |

"But my friend keeps winning"
In the short run, luck swamps the house edge, so plenty of people are ahead after a few bets. That's what keeps them playing. Over hundreds of bets, the edge takes over, and fewer and fewer people stay ahead. Try it yourself in the calculator below.
Both involve risk, but they're opposites in one key way. Gambling has a negative expected value: on average you lose. A diversified, long-term investment has historically had a positive expected return, because you own part of something that grows. Learn more in the Compounding lesson.
House Edge Calculator
Pick a bet, choose how much and how often, and see what the math says. Then simulate 1,000 bettors to see who comes out ahead.
The calculator assumes every sports outcome is a true 50/50, the most generous case for the bettor.
Simulation results change a little each time you run it, just like real luck. Try 1 week, then 3 years, and watch how many bettors stay ahead.
The real costs
For most teens who bet, the cost is money they won't get back. For a smaller group, gambling becomes a disorder that touches every part of life. Gambling disorder is a recognized mental health condition, listed alongside substance use disorders.
Money
Losses can pile up fast for teens with their own cards and accounts. One young man interviewed by the Child Mind Institute ran up about $20,000 in debt over two years. Some teens use parents' credit cards without asking, sell belongings, borrow from friends, or steal to cover losses.
School, sleep and activities
Late-night betting, falling grades, skipped classes, and dropping sports or hobbies. One teen in an NPR story started gambling at 11 and dropped out of college at 19.
Relationships
Secrecy, lying about money, and conflict at home. More than 1 in 4 boys who gamble report stress or conflict because of it.
Mental health
Compulsive gambling is linked with depression, anxiety, substance use and gaming disorder. Teens who gamble are more likely to use illegal drugs.
Gambling disorder carries the highest suicide risk of any addictive disorder, according to the American Psychiatric Association. In a Swedish national study of more than 2,000 people diagnosed with gambling disorder, about 1 in 5 had attempted suicide. Financial stress, shame and conflict all raise the risk.
Most adults agree it's serious: 79% say gambling addiction is as serious as, or more serious than, alcohol or drug addiction.
Warning signs to watch for
- Sudden interest in sports or games they never cared about, or big emotional swings over game results
- Missing money, unexplained cash, or secrecy and lying about spending
- Constantly checking scores, odds or a phone app
- Friend groups centered on betting
- Staying up late, skipping meals, falling grades, skipping school
- Pulling away from friends, family or activities they used to love
- Signs of anxiety or depression
- Any talk of hopelessness or suicide: call or text 988 right away
What families can do
The single most protective step is talking early and often, without lecturing or shaming. Experts from the American Academy of Pediatrics, the Child Mind Institute and the Mott Poll agree on these steps.
Talk
- Use ads and game moments as natural openers
- Ask what they already know and what friends are doing
- Be honest about your own betting; about 1 in 3 parents gamble
- Focus on behavior, not on who your child is
Set limits
- Log out of and lock your own betting accounts
- Turn on transaction alerts for teen cards and accounts
- Require "parent view" on accounts; use blocking software
- Agree on rules for games with loot boxes or real-money spins
Get help early
- Talk with your pediatrician or family doctor
- Treatment works: therapy, support groups, or both
- Don't wait; early help improves recovery

Questions for the dinner table
For teens
- Where have you seen gambling ads or betting content this week?
- Do you know anyone who bets? How do they talk about wins and losses?
- If a friend asked you to bet through their account, what would you say?
For parents
- What gambling does our family already do, like lottery tickets or brackets, and what does it teach?
- Could our teen get into one of our accounts or cards today?
- How would our teen know it's safe to tell us about a problem?
For everyone
- If betting companies keep about $10 of every $100, who pays for all those ads and promo codes?
- Why might a game that feels like "just for fun" lead to betting real money?
- How is buying a stock different from placing a bet?
Our family agreement
Key takeaways
- It's common, and it starts young. More than a third of boys 11–17 gambled in the past year, and most parents don't know.
- Teen brains are more vulnerable. Starting by age 12 makes later problems four times more likely.
- It comes through their phones. Social media, streamers, games and sports apps all push betting.
- The house always wins over time. Every bet has a negative expected value, and parlays are among the worst.
- The costs go far beyond money. Debt, school, relationships and mental health, with the highest suicide risk of any addiction. Help is available 24/7.
