Kalshi Age Requirement: Minimum Age, Verification & How to Sign Up (2026)

Updated March 2026 — Everything you need to know about the Kalshi age requirement, KYC identity verification, which documents you need, state-by-state availability, and what prediction market alternatives exist for users under 18.

Kalshi Age Requirement Explained

How old do you have to be to use Kalshi? The answer is straightforward: you must be at least 18 years old. This is not a guideline or a suggestion — it is a strict legal requirement that Kalshi enforces through mandatory identity verification.

The Kalshi age limit exists for several important reasons:

• Federal regulation. Kalshi operates as a CFTC-regulated Designated Contract Market (DCM). Under federal law, derivatives exchanges must verify that all participants meet minimum age requirements. The CFTC requires that all users of regulated exchanges be legal adults.
• Legal capacity to enter contracts. Event contracts on Kalshi are legally binding financial instruments. In the United States, minors generally lack the legal capacity to enter into binding contracts. Allowing underage users would create legal complications for contract enforcement and settlement.
• Consumer protection. Prediction markets involve real financial risk. The 18+ age requirement is a consumer protection measure that ensures participants have the legal maturity and understanding to accept financial risk.
• Compliance with financial regulations. Kalshi must comply with Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations, which require verifying the identity and age of all users.

For a complete overview of how Kalshi works, including the types of event contracts available and how trading functions, see our dedicated guide.

KYC Verification Process: Documents & Timeline

Kalshi enforces its age requirement through a Know Your Customer (KYC) identity verification process. This is not a simple checkbox where you confirm your age — it is a thorough verification system that confirms your identity, age, and US residency using government-issued documents.

Required Documents

To complete Kalshi's KYC verification, you will need:

How the Verification Process Works

1. Create your account.

   You enter your email address, create a password, and provide basic personal information including your full name, date of birth, and home address.

2. Submit your government ID.

   You upload a photo of your driver's license, state ID, or passport. Kalshi uses automated document verification technology to read and verify the information on your ID. The system checks that the name and date of birth match what you entered, and that the ID is valid and not expired.

3. Enter your Social Security Number.

   Your SSN is verified against federal databases to confirm your identity. This is a standard requirement for all US financial platforms and is necessary for tax reporting compliance.

4. Automated verification.

   Kalshi's system cross-references your submitted information against multiple databases. For most users, this process is fully automated and completes within minutes.

5. Manual review (if needed).

   If the automated system cannot verify your identity — due to document quality issues, name mismatches, or other flags — your application is escalated to manual review by Kalshi's compliance team.

How to Sign Up for Kalshi (Step-by-Step)

If you meet the Kalshi age requirement (18+) and are a US resident, here is how to get started:

1. Visit Kalshi's signup page.

   Go to kalshi.com/sign-up to begin the registration process. You can also download the Kalshi app and sign up directly from your phone.

2. Enter your personal details.

   Provide your full legal name, date of birth, email address, and create a secure password. Your date of birth must show that you are 18 or older.

3. Complete KYC verification.

   Upload your government-issued photo ID and enter your Social Security Number. Most users are verified within minutes.

4. Fund your account.

   Once verified, you can deposit funds via bank transfer (ACH), wire transfer, or debit card. Minimum deposit is just $1.

5. Start trading.

   Browse available event contracts, review market prices, and place your first trade. See our How Does Kalshi Work guide for a full walkthrough of the trading process.

State-by-State Availability

While the Kalshi age requirement is the same nationwide (18+), Kalshi's availability varies by state. As a CFTC-regulated exchange, Kalshi is legal in all 50 states under federal law. However, certain contract types may have state-level restrictions.

Here is the current availability for major states:

Age Requirements: Kalshi vs Other Prediction Markets

How does the Kalshi age requirement compare to other prediction market platforms? The answer depends largely on whether the platform is regulated, crypto-based, or play-money.

Key Differences in Age Enforcement

• Kalshi vs Polymarket.

  Kalshi strictly enforces age verification through government ID and SSN. Polymarket does not perform KYC for most users because it operates as a crypto-based platform outside US jurisdiction. While Polymarket's terms of service require users to be 18+, the lack of identity verification means there is no mechanism to enforce this. Polymarket also officially blocks US users entirely, making it inaccessible regardless of age for anyone in the United States.

• Kalshi vs Robinhood.

  Both Kalshi and Robinhood require users to be 18+ and enforce this through comprehensive KYC verification. The process is nearly identical: government ID, SSN, and personal information verification. Robinhood's prediction market features (event contracts) are subject to the same age requirements as its brokerage services.

• Kalshi vs play-money platforms.

  Platforms like Manifold Markets and Metaculus do not involve real money and therefore have minimal or no age restrictions. These are the only realistic prediction market options for users under 18.

What Happens If You Are Underage

Attempting to use Kalshi while under 18 is not just against the platform's rules — it can have real consequences. Here is what you need to understand:

Account Termination

If Kalshi discovers that a user is under 18 — whether during the initial verification process or after an account has been created — the account will be immediately terminated. This includes:

• All open positions will be liquidated at the current market price
• Account access will be permanently revoked — you will not be able to log in
• Any remaining funds will be returned, minus any applicable fees or penalties
• You will be banned from creating new accounts — Kalshi maintains records to prevent repeat attempts

Legal Consequences of Submitting False Documents

Attempting to bypass Kalshi's age verification by submitting fraudulent documents is a serious legal offense:

• Identity fraud. Using someone else's ID or a forged document to open a financial account constitutes identity fraud, which is a federal crime under 18 U.S.C. § 1028. Penalties can include fines and imprisonment.
• Wire fraud. If false identity information is transmitted electronically (which it is during online KYC), it may also constitute wire fraud under 18 U.S.C. § 1343.
• Contractual liability. Any contracts entered into by a minor using false identification are legally voidable, creating potential disputes over settlement amounts.

Parental Consent: Why It Does Not Apply

A common question from younger users and their parents is whether parental consent can allow a minor to use Kalshi. The answer is no, and here is why:

Regulatory Requirements Override Parental Permission

Kalshi's age requirement is not a company policy that can be waived — it is a regulatory obligation. As a CFTC-regulated Designated Contract Market, Kalshi is required by federal law to verify that all users are legal adults. No amount of parental consent can override a federal regulatory requirement.

Why Custodial Accounts Are Not Available

Some financial platforms (like certain brokerage accounts) offer custodial accounts that allow a parent to manage investments on behalf of a minor. Kalshi does not offer custodial accounts for several reasons:

• Event contracts are active trading instruments — unlike long-term investments, they require real-time decision-making and acceptance of immediate financial risk
• CFTC regulations for DCMs do not include provisions for custodial trading accounts the way SEC regulations do for securities brokerages
• Each account must be tied to a verified individual who is personally responsible for all trading activity and tax obligations

Can a Parent Open an Account for Their Child?

No. A parent opening a Kalshi account in their own name for a minor to use would violate Kalshi's terms of service, which prohibit account sharing. Each account must be used exclusively by the verified account holder. If Kalshi detects that an account is being used by someone other than the verified holder, the account may be suspended or terminated.
