Episode notes
Regulation Explains Different Market Rules
- Kalshi follows U.S. law as a CFTC-registered exchange which shapes which markets it allows.
- Polymarket's international platform is based in Panama and mainly operates outside CFTC jurisdiction, so different rules apply to its war markets.
Institutional Partners Shape Platform Strategy
- Traditional financial partners like Intercontinental Exchange may view prediction markets as gambling risk, especially when markets cover war or leadership outcomes.
- That reputational concern helps explain why regulated Kalshi emphasizes compliance while Polymarket keeps much activity offshore.
Companies Took Different Stances On Iran Markets
- Kalshi proactively blocks markets tied to death and froze a market about Iran's supreme leader when resolution questions arose.
- Polymarket keeps overseas war markets on its international site and treats U.S. operations as geo-blocked, creating a practical firewall.
