4-bullet brief | narrative
  • Kalshi prices a positive economic outcome at 62%, Polymarket at 55%, a 7pp gap
  • Kalshi is higher; Polymarket holds roughly 2.6x more cumulative volume
  • Subjective resolution language ('state of the economy') likely drives divergence, venues may use different adjudication sources or crowd definitions
  • Resolution depends on the specific scoring criteria each platform applies to economic conditions at year-end 2026
