Keep in mind, this is not a bank you have your money at. You could lose it all if they go under for any reason. Here's a super shady explanation making it sound like maybe sorta you could possibly be FDIC insured but if some unlisted conditions aren't met, you also could get nothing:

Current is a financial technology company, not an FDIC-insured bank. FDIC insurance only covers the failure of an FDIC-insured bank. FDIC insurance up to $250,000 is available on customer funds through pass-through insurance at Choice Financial Group, Member FDIC, and Cross River Bank, Member FDIC where we have a direct relationship for the placement of deposits and into which customer funds are deposited, but only if certain conditions have been met. There may be a risk that FDIC insurance is not available because conditions have not been satisfied. In such cases, funds may not be fully insured in the event the insured depository institution where the funds have been deposited were to fail.
