Thesis

Why the estimate deviates from the market

  1. 1.Order book shows bid-side pressure (+100.0% imbalance within 5% of mid) on $6,256 of depth. [book_imbalance v1.0.0, weight 0.33]

Counter-thesis

Why this may be wrong

  1. 1.Model confidence is 0.13; the estimate is shrunk heavily toward the market price and should be treated as weak.
  2. 2.Only $0 of depth within 5% of mid; size is limited and slippage will reduce realised edge.

Key catalysts

  1. 1.Resolution in 56.0 days; price convergence typically accelerates near expiry.

What would invalidate this

  1. 1.Market price moving to 13% would close the gap.
  2. 2.A reversal in the order-book imbalance or trade-flow direction that drove this estimate.
  3. 3.Liquidity falling materially below $6,256 would make the edge uncapturable regardless of accuracy.

Resolution criteria

This market will resolve according to the party that wins control of the United States House of Representatives in the 2026 United States midterm election. A party wins control of the United States House of Representatives if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the chamber will be deemed controlled by the party with which the first elected Speaker of the House of the Congress that convenes after the 2026 midterm election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All House elections in the 2026 United States midterm election that elect voting members and determine representation in the upcoming 120th Congress are included. Where a seat is decided by a runoff, the runoff result will determine attribution of that seat. Seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. House members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, a party are included in that party’s count. If the caucus decisions of members of the House elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party. The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.
