Is Kalshi Gambling? What Parents Need to Know About Prediction Markets

Some of us found out about prediction markets from a commercial. Sitting there watching the World Cup, or a Sunday game, and there it is between plays. Slick, fast, a celebrity you recognize. Something in the back of your head goes huh, that’s new. And then the game comes back on, and you forget about it.

Some of us found out from a phone. An app that looked like a stock trading app. Green numbers, red numbers, a chart. And when we asked, we got an answer that sounded reasonable.

“It’s not betting, Mom. It’s trading.”

Maybe you let it go. Maybe you felt relieved.

Or maybe you were glad. That’s the one nobody says out loud, so we’ll say it. Some of us encourage this. We want our kids to be responsible with money. We want them saving, investing, thinking past Friday night. So, when a nineteen-year-old starts talking about markets and probability and having a position on something, that sounds like a kid growing up.

If that’s you, please hear this. That wasn’t a failure of judgment on your part. Why would you have thought anything else? Legally, this isn’t gambling. No state gaming commission licenses it. Nobody whose actual job is to prevent problem gambling oversees it. It doesn’t come wrapped in the responsible gambling messaging we’ve all gotten used to seeing at the end of a sportsbook commercial. It’s regulated by the federal agency that handles commodities and futures, the same one that oversees contracts on soybeans and interest rates.

Nobody told us this was gambling. The law says it isn’t.

And maybe underneath all of it, some part of you knew something was off but couldn’t say what, and you didn’t want to be the parent who assumes the worst about everything.

We’ve been there. So, let’s talk about what these platforms actually are, why they’re suddenly everywhere, and what they mean for our kids.

What is a Prediction Market?

Strip away the language, and it’s simple. You’re buying a yes-or-no answer to a question about something that hasn’t happened yet.

Will the Chiefs cover the spread? Will this candidate win? Will it rain in Dallas on Tuesday? You buy a contract for somewhere between one cent and ninety-nine cents. If you’re right, it pays out a dollar. If you’re wrong, you get nothing.

That’s it. That’s the whole product.

The pricing is what makes it feel like finance. A contract at sixty-five cents means the market thinks there’s roughly a sixty-five percent chance the thing happens. You can buy and sell before the event resolves, watch the price move, get out early, double down. It has the rhythm and the vocabulary of a trading floor.

But you’re picking a side and risking money on an uncertain outcome. Our kids know this. They’re not confused about it.

One more piece of this is worth knowing, because it’s the question a lot of us ask first: Who’s on the other end? Every contract has two sides. If your child buys YES at sixty cents, there is a NO side worth forty cents, and when the market settles, the winning contract pays a dollar. Kalshi isn’t acting like a traditional sportsbook taking the other side of the bet or setting a betting line. It operates the exchange and collects fees on trading.

That can sound fairer than a sportsbook—until you ask who your kid may actually be trading against. The person on the other side isn’t necessarily another 20-year-old making a guess from his phone. It may be a sophisticated trader or professional market maker with better data, better models, automated trading tools, and far more experience and capital. Our kids understand that someone is on the other side of the trade. What they may not understand is just how uneven that matchup can be.

Young people aren’t being fooled by the language of “prediction markets” or “event contracts.” They understand that they’re putting money on an outcome and can win or lose depending on what happens. The bigger concern is how normal that behavior has become. Betting is now so woven into watching sports, following the news, and scrolling a feed that putting money on what happens next can feel less like gambling and more like simply participating in the world around them.

The language isn’t fooling them. It’s fooling the rest of us, and it’s what made all of this legal in the first place.

Why is this Suddenly Everywhere?

Because it got big fast.

Kalshi handled under two billion dollars in trades in 2024. Almost twenty-four billion the next year. Then, in June of this year alone, more than thirty-one billion. One month beat the entire year before it. Kalshi added three million new users during the World Cup. During the 2026 World Cup, analysts estimated prediction markets accounted for more than a quarter of all the legal sports betting in this country, up from less than a tenth in January.

Kalshi isn’t the only name to know. Polymarket is the other major platform, running under the same federal rules and the same eighteen-and-up minimum, and its U.S. app is now open in most states.

And this isn’t only happening on specialty apps. Robinhood, the brokerage where a lot of young people opened their first investment account, now offers the same event contracts. In the second quarter of 2026, Robinhood made more money from event contracts than from stocks or crypto. More than ten times what it made a year earlier.

Think about what that means for a twenty-year-old with the Robinhood app already on his phone. He doesn’t have to download anything or hide anything. The betting is one tab over from his index funds.

The Part Most Parents Don’t Know

In most states, you have to be twenty-one to walk into a casino, and twenty-one to open a sportsbook account. But prediction markets are regulated federally as financial markets, not as gambling, and the minimum age is eighteen. Same as opening a brokerage account.

So, an eighteen-year-old freshman who legally cannot place a bet at a sportsbook can trade sports contracts on his phone from his dorm room. In most of the country, including states with no legal sports betting at all. A handful of states have fought back and gotten sports contracts blocked or limited, and those cases are still working through the federal courts. Most states haven’t.

And the eighteen-to-twenty crowd has found it. Of course they have. It’s the easiest door open to them.

And Now the Sportsbooks are Doing it Too

This is the part that caught us off guard.

At the end of 2025, DraftKings launched its own prediction market app in thirty-eight states. FanDuel followed within days and had prediction markets in all fifty states by mid-January, adding sports contracts state by state after that. Fanatics beat both of them to it. All of these run through federally regulated exchanges, which means they operate under the same eighteen-and-up rule.

The same company runs two apps. On the sportsbook, your kid has to be twenty-one in most states, and a state regulator is watching. On the prediction app, he has to be eighteen, and it works in California, Texas, Florida, and Georgia, where that company’s sportsbook can’t legally take a bet at all.

When the Boston Globe covered DraftKings moving into this space, an industry analyst described picking up customers at eighteen instead of twenty-one as the revenue opportunity. Not an unfortunate side effect of the regulation. The opportunity.

Why this Worries Us Even More than a Sportsbook Does

A few reasons, and they aren’t technical ones.

There’s no off switch. A football season ends. Prediction markets never close. There’s always an election, an economic report, a weather outcome, an awards show, a crypto price. Something is always resolving. For a young person whose gambling follows stress or boredom or loneliness, there is no natural stopping point built into the calendar.

Losing looks like strategy. This one matters. When someone chases losses at a sportsbook, most people can name it. When someone chases losses on a platform that calls it a position, he can tell himself he’s averaging down, managing risk, waiting for the market to correct. He can say it to us, and it sounds sophisticated. He can say it to himself and believe it. The vocabulary gives him a place to hide, and it delays the moment when he recognizes there’s a problem.

He isn’t playing against the house. He’s playing against whoever took the other side of his trade, and the accounts winning consistently on these platforms are professionals running automated strategies at a speed and volume no nineteen-year-old is matching. He doesn’t experience it that way. He experiences it as himself against a question he believes he knows the answer to. Every published analysis we’ve seen puts the share of users losing money somewhere between seven and eight in ten, with a fraction of one percent taking most of the winnings.

The safety nets don’t reach here. This is the practical one, and it’s the reason we wanted to write this post. If your son or daughter is in recovery and has enrolled in a state self-exclusion program, that program almost certainly does not cover prediction markets, because the state doesn’t classify them as gambling. The blocking apps many families rely on may or may not catch these platforms depending on how they’re accessed. If your family is using self-exclusion or blocking software as part of a recovery plan, check directly whether these specific apps are covered. Don’t assume.

What We’d Watch For

None of these prove anything on their own. They’re just worth noticing.

• New interest in “investing” or “trading” that came on suddenly and intensely
• Watching games, weather, elections, or news with unusual stakes attached
• Money moving through Venmo, Cash App, or crypto in patterns that don’t add up
• Being on the phone at odd hours, especially around big cultural or sporting events
• Mood that rises and falls with something you can’t identify
• Defensiveness that shows up specifically when you ask about the trading app
• Talk about a strategy, a system, or an edge

If You’re Seeing This in Your House

Don’t lead with the vocabulary fight. It’s tempting to want to win the argument about whether it’s really gambling, and it goes nowhere.

Ask about the money instead. How much is in the account? Where it came from. Whether it’s been up and down or mostly down. Money is concrete, and it’s harder to argue with than a definition.

Ask how they feel when they’re doing it, and how they feel after. You’ll learn more from that than from any argument over definitions.

And if what you’re finding scares you, please don’t try to fix it by covering the losses. We know the pull of that impulse. We’ve felt it. But paying off gambling debt doesn’t create a fresh start. It creates room to keep going. The money is the symptom, not the illness, and protecting access to it is one of the few things we actually control.

You don’t have to have this figured out before you reach out for help. Most of us didn’t.

You’re Not the Only Parent to Experience This

If any of this sounds like your house, a lot of us have sat where you’re sitting, staring at an app on a phone, trying to work out whether we were overreacting.

You’re probably not. Reach out to us if you need support dealing with this. We are here for you.
