Is my jumping spider molting or laying eggs?

[Hufflesocks]

I have a Phipidus Clarus that I caught from the wild recently. He is the first jumping spider I have owned recently he started spinning this thick nest. I have put food in there and it gets his attention at first but then he ignores it and goes back to actively building his nest. The only reason I think he might be laying eggs is because I am unsure if he is actually a he. I attached a picture of the nest. Thank you so much for the help!

that looks like an egg laying nest, to be honest, but some do make very elaborate molt nests. Personally, i would assume eggs, though!
