Not my scope of expertise, but I believe corporations are prohibited from donating money directly to a candidate based on federal campaign laws. They could of course give money to an action committee, but there are lots of restrictions on coordination between the two. So I guess Facebook could fund his campaign via a PAC as long as Zuckerburg himself had nothing to do with the strategy. That would be an odd campaign. More likely Zuckerberg could fund the campaign himself via gifts or loans - this is what Trump did (not fully of course, but he did gift/loan some money).
