I recall a few finance papers saying (paraphrasing) "approximately all private info is reflected in stock prices". The same is obviously true of prediction markets. If government officials are banned, they'll just give a little wink to a relative or friend, and the prediction markets will reflect the private information.
On a personal note, I find these markets incredibly useful in day to day life. There's been a joke for a while that putting site:reddit.com in your google search is the only way to get (some) real information. It's becoming true that putting <search terms> AND (kalshi OR polymarket) is how to get accurate info.
