Frequently asked questions

What is a prediction market contract?

It is a contract tied to a defined event. Read its resolution criteria, deadline, settlement source and exception rules.

Does a $1 payout mean $1 profit?

No. Profit is payout minus purchase cost and applicable fees. A losing contract can lose the amount paid and fees.

Does a reward make a trade risk-free?

No. Rewards have eligibility and qualifying terms. They do not remove the risk of losing money.

What should you check before registering?

Check age, location, product and account eligibility, current fees, funding and withdrawal conditions, and the written contract rules.
