Check settlement rules before comparing contracts. Matched outcomes may settle differently. These venues also report end dates more than 48 hours apart; event identity does not mean the contracts close or settle together. These are stored prices; record update times do not certify live quotes. Differences exclude fees and available size.

Known rule differences between venues

  • Kalshi settles on the party of the officeholder sworn in/inaugurated for the new term; Polymarket settles on the party of the called winner. They differ if the winner dies, withdraws or is not seated before the term starts.
  • Independents: Polymarket assigns a non-affiliated winner by stated caucus (House) or excludes independents from party options (Senate/Governor); Kalshi requires party membership.

A shared identity alone does not make a price difference executable.
