Ask HN: What are the algorithms used by predictions markets like Polymarket?

Doesn't "POTUS is using threads for social media" feel a bit like "POTUS is using outlook.com for email"? Is there anything about the bureaucracy that stops their some small team to setup a Mastodon server on "social.whitehouse.gov" and make this a reality? I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform. Also, none of this seems to be a problem for some of the EU governments. Maybe I am missin...
