An 18-year-old freshman may not be old enough to place a legal sports bet in Tennessee. But this fall, they can nonetheless walk into their dorm room, pull out their phone and make the same wager anyway.
So-called prediction markets, popular platforms like Kalshi and Polymarket, let users as young as 18
all across the country gamble on everything from sports to what word might be mentioned at a press conference.It doesn’t matter what the laws are in Tennessee or any other state. Unlike traditional online sports betting apps, these platforms don’t abide by state age minimums, nor do they provide problem gambling resources to prevent addiction.
Instead, these companies insist
they are federally regulated financial exchanges – investment tools – not sportsbooks. But for a college freshman with a Venmo balance and a favorite team, the distinction is meaningless. It is sports gambling.

Tennessee's betting age doesn't apply to prediction markets
Most parents assume the guardrails are in place. Tennessee requires sports bettors to be at least 21, but prediction markets offer sports contracts to 18-year-olds. About 80% of voters in Tennessee believe that prediction markets should be required to follow the same state gaming laws as licensed sportsbooks, according to Morning Consult polling conducted earlier this year.
Prediction markets claim they cannot be regulated by states. Working with the Commodity Futures Trading Commission (CFTC), they argue they are akin to the New York Stock Exchange but for sports. That has opened up sports gambling to anyone as young as 18, including college students in Tennessee who are below the state’s legal sports-betting age.
These platforms are also reportedly targeting college campuses with aggressive marketing, sponsoring college clubs and paying student influencers to popularize them with peers. The NCAA has called for the CFTC to pause prediction market offerings on college sports until safeguards are implemented, but that request has gone unheeded.
Calling it investing doesn't change the risk
As your student heads off to campus this fall, they will face hundreds of betting opportunities every week and an advertising blitz already ramping up. Freshmen will see ads during game breaks in dorm lounges. They will watch classmates open the apps between lectures. And they will be told, over and over, that they are not gambling – they are "investing."
That framing is the most dangerous part. Investing is about ownership, long-term growth and building a future. Wagering on whether the Volunteers will cover the spread this weekend is not investing, no matter how sleek the interface. Wrapping a bet in the language of Wall Street does not change what it is; it only makes it easier for a smart, financially inexperienced 18-year-old to talk themselves into it.
The science is clear. The prefrontal cortex, the part of the brain that governs impulse control and long-range judgment, is not fully developed until the mid-twenties. That is one reason most states with legal sports betting set the minimum age at 21. It is also why the American Psychiatric Association classifies gambling disorders alongside substance addictions, and why young men in college are among the highest-risk populations for developing one.
Time for an honest conversation with your kid
As you zip up that last suitcase, smooth the comforter one final time and hug your child goodbye, you'll be thinking about all the things you hope for them – that they will find lifelong friends, stay safe, work hard and make choices that lead toward a bright future.
We can’t walk with our children every step of the way, but we can have honest conversations about the world they’re entering. This fall, make sure one of those conversations is about sports prediction markets and the risks of conflating gambling with investing.
