Why on earth would you want to let someone know that you had a big payout?

One reason is that it can help attract talent & useful connections. If you're a known billionaire, I imagine it's pretty easy to get a meeting with anyone, which could lead to educational & enriching conversations that you otherwise wouldn't have access to.

I'm curious if there's information from ppl who've experienced this type of publicity, where they thoughtfully evaluate the pros & cons, and evaluate how they net out.
