How this market settles
What could still go wrong
- The exact date of the new Congress convening is not specified beyond 'after November 3, 2026' and before the end date of 2027-02-01T15:00:00Z — if Congress does not convene by that end date, resolution is unclear.
- Definition of 'end of the day' the new Congress convenes is ambiguous regarding timezone.
- No specific official source (e.g., Senate clerk records) is designated for confirming seat counts.
- Treatment of seats that become vacant or disputed between election day and the convening of Congress is not fully detailed beyond 'vacant and disputed seats count toward no party'.
- Whether a senator-elect who has not yet been sworn in counts for their party or as vacant/disputed is not explicitly addressed.
