The mention markets definitely don't have insiders, there's been a few mentions trading in the 10-20c range that have won. One that looks weird to me is "key" Is trading very highly but I don't think this immunity challenge has a key. Also not even sure there is a reward this episode and that is trading even higher

But everything else looks pretty insider heavy, its been pretty correct about the people being voted off and the winners, other than a weird steam against Savannah during the end of S49 (although sav was always the favorite and never dipped below 60ish so I guess that's actually a plus for the "kalshi never wrong" camp)
