You will trade with the same account balance that you traded in your Challenge. If you traded with $100,000 in Challenge, you would also have access to a fictitious $100,000 on a Live Account.
To avoid any confusion, please note that all accounts we provide to our clients are demo accounts with virtual funds. After a client becomes a funded trader, they're provided with login credentials for a demo account and are entitled to a portion of profits generated from their trades.
If you wish to trade with a higher account balance, you can simply apply for another Challenge. Each Challenge needs to be traded from the beginning, regardless of whether you have passed one in the past.
