- q: "Can US users trade election prediction markets?"
a: "On Kalshi, yes. Kalshi is CFTC-regulated and explicitly covers US political events including congressional races, presidential elections and policy markets. On Polymarket's international exchange, no: US IPs are geoblocked following a 2022 CFTC settlement. Polymarket US (QCX), launched December 2025, may offer political event contracts but initially launched with a limited set. For US political market trading today, Kalshi is the primary regulated option."
- q: "Why do political markets take longer to resolve than sports markets?"
a: "Two reasons. First, outcomes wait on authoritative sources: Polymarket markets typically do not resolve until an authoritative call is made (AP election call, official certification, court ruling). This can take hours to weeks after the event. Second, the UMA dispute rate is higher on political markets because contested outcomes attract challengers during the dispute window. Both factors extend the median resolution delay relative to sports markets. OpenChainBench measures this live: the current politics median is {{p50:politics}} versus sports at {{p50:sports}}."

a: "On market depth and variety: Polymarket. On US regulatory access: Kalshi. Polymarket has deeper books and higher open interest on major political events, including international elections Kalshi does not cover. Kalshi is the compliant option for US users and covers major US political events. Resolution delay is likely similar in magnitude but through architecturally different systems: Polymarket is onchain via UMA, Kalshi is offchain via the exchange's settlement process."
