What is the name of the FTX stock?

Excuse me, I'm a bit confused about the terminology in the cryptocurrency and finance world. Could you please clarify for me? I've heard about FTX, but I'm not entirely sure if it's a stock or a cryptocurrency exchange. If it's indeed a stock, could you tell me what the official name of the FTX stock is? I'm interested in investing in this space and want to ensure I'm making the right decision. Your expertise in this field would be greatly appreciated.
