Frequently asked questions
Can I use a credit card on Polymarket?
Payment options vary; the deposit screen shows what's available. Many banks block gambling-type card payments, so a debit card or bank transfer is usually more reliable.
Why did my Polymarket deposit fail?
Common causes: your bank blocked it, your identity isn't fully verified yet, or you're outside an eligible state. Try another method or contact support.
