the scrutiny is justified when you see fresh wallets placing six-figure bets on presidential actions minutes before announcements. the onchain transparency of Polymarket is a double-edged sword tho - it makes the suspicious activity visible but doesnt prevent it. Kalshi at least has KYC and CFTC oversight which theoretically adds an enforcement layer, but the same kind of insider trading can happen there too, it just leaves less of a public trail.
