How old do you have to be to use Kalshi?
You have to be 18 to trade on Kalshi. That's younger than the 21 many people expect from casinos and some sportsbooks, and the reason is the same one behind most things that make Kalshi different: it's a federally regulated exchange, not a gambling operator.
- Casino and sportsbook age minimums come from state gambling law, where 21 is common.
- Kalshi is required to verify identity, so signup involves standard KYC: your legal name, date of birth, Social Security number, and sometimes a document check.
- Being old enough is the easy part.
Why 18 and not 21
Casino and sportsbook age minimums come from state gambling law, where 21 is common. Kalshi's event contracts are derivatives on a CFTC-regulated exchange, and the standard for opening a trading account, like a brokerage account, is being a legal adult: 18.
So the age requirement follows the financial-markets rulebook, not the casino rulebook. Same reason an 18-year-old can open a stock brokerage account but may not be able to walk onto a casino floor.
What verification involves
Kalshi is required to verify identity, so signup involves standard KYC: your legal name, date of birth, Social Security number, and sometimes a document check. There's no practical way around it, and attempting to trade on someone else's account violates the exchange's rules and can get funds frozen.
That verification also ties the account to you for taxes: your gains are reportable income from day one, whatever your age.
If you're a young trader, a word of honest advice
Being old enough is the easy part. The market doesn't care about your age, but it will absolutely take your money if you skip the fundamentals: read prices as probabilities, size small, expect variance to swamp small samples, and track your results honestly from trade one.
Starting young with a clean record of every trade is genuinely an advantage, you'll know whether you have an edge years before most people even think to measure it.
