Hi, Yale Wale,
I think both of them are grammatically correct. I guess that's because it isn't clear what 'any' refers to here. What does the speaker have in mind? One single person or more? It is up to the speaker.
Michael Swan 3rd edition, page 48, states that:
"Note that when 'any of' is followed by a plural subject, the verb can be singular or plural. A singular verb is more common in a formal style.
- If any of your friends is/are interested, let me know."
