The regulatory landscape
The US financial regulatory landscape is divided among several agencies, with the Securities and Exchange Commission (SEC) overseeing stock markets and various other securities. The SEC aggressively pursues unlawful insider trading cases when people trade securities based on material non-public information. Former SEC official John Reed Stark explains, “The rationale for policing unlawful insider trading is that for the markets to work efficiently and fairly, everyone needs to be working with the same basic information, or at least, that those with special access to nonpublic information are prevented from taking advantage of it before other investors.”
But with the Commodity Futures Trading Commission (CFTC), which oversees prediction markets, it’s a different world. Trading based on non-public information is built into the system: a cattle rancher can use early calving data to hedge against future beef prices, even though others lack access to that information. Laurian Cristea, a lawyer specializing in financial services and CFTC exchanges, explains, “it’s not wrong to trade on information you properly know or developed through your business.” Nevertheless, rules against fraud or market manipulation still prohibit trading based on illegally acquired private information, or making false or misleading statements that impact markets, and CFTC-regulated exchanges like Kalshi are required to establish and enforce their own rules to maintain fair markets
