pump.fun doesn’t fit here, how could there be insider trading there? If anything, it would be something like Polymarket
There have been an insider trading lawsuit against the Solana foundation and Pump fun a few months ago (based on private conversations with the teams if I'm not mistaken). I'm not sure how serious it was, or what happened since then though.
Polymarket or Kalshi could definitely be it too, but then what would the employees have as information that could help them place bets?
For example, Michael Saylor could bet on whether he's buying more than 500M BTC this month... Or someone on the White house betting on who's Trump choosing as Fed Chair or SEC chair... but the Polymarket employees, where do they fit on all of this especially when this was happening "over prolonged period of time"? Assuming there is nothing they can do from the backend to cheat the system and everything is verifiable through smart contracts.
As for bets about Polymarket itself, I can't imagine that as something being legal?
