Facts
What Is the Kalshi Age Requirement in The US?
18. This is the Kalshi age requirement and there are blockers and restrictions in place to make sure that those under 18 cannot physically sign up here.
We have always been impressed with how Kalshi tackles things like fraud, age protection, and insider trading, and some of these features include geoblocking, 2FA for account logins, and a requirement for a full KYC check just to register an account.
