Fidelity only offers brokered CDs AFAIK. You can try to sell them on a secondary market like bonds if you can't wait till maturity. Note each offering may or may not be called back (early maturity) on a schedule if they no longer like your rate. Callable have better rates, typically. If I am buying a CD, I prefer non-callable. The interest is paid out periodically into your cash holdings. They claim they are covered by FDIC, maybe indirectly, IDK. I have had several over the years and no problems.
