Does ATOM have unlimited supply?

Could you please clarify for me whether ATOM has an unlimited supply? I've been reading about cryptocurrencies and their various characteristics, and it seems that supply is a crucial factor that affects the value and stability of a coin. Given that ATOM is a relatively well-known cryptocurrency, I'm particularly interested in understanding its supply mechanism. Is there a cap on the total number of ATOM coins that can be issued, or is it potentially infinite? Your insight into this matter would be greatly appreciated.
