Kalshi Age Requirement

As you would expect to find at a CFTC-regulated prediction market platform, there’s a strictly-enforced Kalshi age requirement. As event contracts are trading products, you’ll need to be at least 18 years old to access them from any US state. We’ll provide you with a very brief overview of Kalshi, before moving on to the platform’s availability and discussing the ways in which Kalshi verifies everyone who trades on the site. We’ll also introduce you to the Kalshi Policy Center, where you’ll find a lot of useful material covering how the platform maintains a fair and secure trading environment.

A brief overview of Kalshi and event contracts

Kalshi operates as a Designated Contract Market exchange, and as such is regulated by the Commodities Futures Trading Commission (CFTC). This permits Kalshi to offer prediction markets to traders. The platform offers thousands of individual event contracts in multiple categories. Each contract only has two outcomes, typically either a Yes or No answer. You’ll find a percentage assigned to each side, which totals at 100%. The percentages define the probability of the event happening, based on the opinion of all users who have purchased a contract on either side.

State availability

It was always expected that prediction markets would undergo changes due to ongoing pressure at state level, despite this type of trading being regulated at federal level. Until recently, Kalshi was available in all 50 US states, but as of June 2026 the platform’s level of availability has changed. Further changes are likely, so there is little point in us detailing the current situation. Suffice to say that if you can see Kalshi listed on the banners of this page, then you can open an account on the platform, provided you are at least 18 of course.

Confirmation of the Kalshi age requirement

Judging from Kalshi reviews left by users, and various forum posts, many people are confused as to whether the minimum age requirement at Kalshi is 18 or 21 years. The vital fact to remember here is that Kalshi operates as a regulated trading exchange, and as such US citizens aged 18 years or above are permitted to sign up. Part of the sign up process requires KYC verification, so it’s wise to have the following documents ready to upload:

• Proof of ID: Passport, driver’s license, or a state-issued photo ID card
• Proof of residence: A recent utility bill, or bank statement
• Employment: SSN, current employer details and job role

The Kalshi Policy Center

As we’ve demonstrated, Kalshi is a reputable prediction trading platform, and as such it takes CFTC regulations very seriously. One of the brand’s most stringent policies concerns the potential for underage users accessing the site. To underline how committed Kalshi is, it’s worth a visit to the Policy Center. You’ll find the link in the Footer section of the brand’s website. There you will find a page titled ‘Trust & Safety for Families’ containing detailed guidelines for parents who are concerned that their underage children may be able to access the site. Recommendations include:

• Enabling facial recognition on your device
• Implementing two-factor authentication (2FA)

For anyone with concerns about identity misuse, Kalshi provides a tool called ID Check, which you can use to make sure that nobody has used your identity to open an account at Kalshi. Other documents found within the Policy Center include Responsible Trading tools, information about the steps Kalshi takes to prevent insider trading, and banned markets. The last item on the menu, titled Market Integrity, contains a number of ‘must read’ articles relevant to all traders.
