Kalshi Age Requirement: Minimum Age for Predictions Betting 2026

Updated: Jan 27, 2026, 11:04 AM ET

Kalshi is an online prediction market where you can buy contracts predicting the outcomes of real-world events, be it the Governor’s next move or the song to likely scoop the Grammys. But what’s the Kalshi age requirement?

You must be at least 18 years old to join Kalshi. After all, like trading on the stock market, buying and selling contracts on the site involves risk. On the upside, signing up with the online prediction site is pretty simple, provided you meet the eligibility criteria. We’ll unpack these aspects in our guide, with age being our primary focus.

Buy and Sell Event Contracts

Before we discuss how old you need to be to use Kalshi, let’s unpack what this prediction market site is all about. Unlike conventional betting sites, it’s a predictions market where users forecast the outcomes of different future events, from sports and politics to the weather. You participate by buying and selling event contracts.

Kalshi structures its event contracts as Yes/No questions that pay $1. You can be asked to predict the sporting team to win, or a global trend. For example, if you buy a Yes contract for $0.60 and your guess is correct, you get $1. A Kalshi age requirement becomes necessary, since real money is on the line. For newcomers, there is also a $10 Kalshi sign up bonus you can claim so long as you meet the bonus terms.

Your Age Matters

You can’t liken the Kalshi prediction site to a regular betting platform because they aren’t the same. No betting happens at Kalshi, only buying, selling or trading of contracts. Still, you must observe the Kalshi age requirement to be a part of the action.

18 Years and Up

So, how old do you have to be to use Kalshi? You can only access Kalshi if you’re at least 18 years old. Why? For one, it’s the law. Kalshi is an upstanding site that adheres to US laws and the Commodity Futures Trading Commission (CFTC) rules. On a site level, Kalshi can only enter binding contracts with persons who’ve attained the age of majority. As such, Kalshi will ask for your verification documents to confirm your age.

Differences Between Site Rules and Regional Laws

Is Kalshi legal? Yes. It’s one of the largest prediction markets in the world, and was recently greenlighted in the US and is now legal in some states. The CFTC already set the age limit for trading to 18. That’s one of the reasons why the Kalshi age is set at this limit.

Why the Kalshi Age Requirement Matters

The Kalshi age requirement is in place to prevent minors from entering into financial commitments they aren’t old enough to fully understand. Here’s why.

Only 18 Years and Up Can Meet the Kalshi Age Requirement

Who knew that you could buy contracts predicting things like who’ll be the next TIME’s person of the year? Kalshi allows you to guess the outcome of just about anything, including crypto, sports, politics, and the weather. This isn’t just guesswork, but you can turn a profit if you sell your contracts at higher prices. Of course, you’ll need to take the 2% Kalshi fees into consideration.

Because you’re buying and selling event contracts, you must be above the Kalshi age requirement to enter a legally binding contract. The idea is to pick a reputable prediction site, and Kalshi is legit in pretty much all aspects.
