Kalshi is regulated and trading in this way on Kalshi is explicitly illegal. PolyMarket does not operate under US laws and I don't know if the same insider trading rules are a separate violation on top of just participating.
Why would Polymarket not operate under US laws? It's based in New York, and has already been fined by the CFTC. It's all in the wikipedia page.
