What a native Spanish speaker would actually say
English puts both people’s guesses on the same level. Spanish compares their knowledge directly, without talking about guesses.
Both can be friendly admissions of shared uncertainty. A sharp tone can also make either reply sound impatient with the question.

What are other ways to say it in Spanish?
Sé lo mismo que tú
Literally: “I know the same as you”

No tengo ni idea
Literally: “I do not have even an idea”
A more emphatic admission of not knowing; it does not compare the two speakers.
