4-bullet brief | narrative

Kalshi puts 35% on Iowa electing a governor and senator from the same party, reflecting a competitive state where split outcomes remain the base case.
Trading volume on this contract surged 695x day over day, a sharp signal that the primary results are pulling fresh attention to Iowa's general-election setup.
Companion Kalshi contract CM-EVT-5BB4SFW2V1 prices Michigan's same-party sweep at 53%, showing the market sees Michigan as more likely to unify than Iowa.
Resolves via Bureau of Labor Statistics as named resolution source; actual resolution will depend on official certified election results.
