My impression is that Wikimania is pretty well self-funding: part of the bid process is coming up with sponsors to cover the expense of running it.
I assume the sponsors end up covering most of the expenses, but the Foundation's planned spending distribution [1] does budget $150,000 for Wikimania. That's a modest 3% of the total budget, but Wikimania sponsorship apparently isn't so overwhelming as to cover everything.
