BitMEX co-founder Arthur Hayes at Inside the Blockchain 100 called for the legalization of insider trading on prediction markets, arguing that insiders possessing material information should be allowed to trade on platforms such as Polymarket and Kalshi, as doing so accelerates price discovery and reveals geopolitical developments ahead of public announcements. Hayes dismissed media criticism of politicians and political families trading on these platforms, saying such activity should be encouraged. He also flagged the forthcoming launch of HIP4 on Hyperliquid as a further step toward transparency in global governance.
