Contract Snapshot
A "Yes" resolution for a specific outcome (e.g., Shutdown & Democratic Party) occurs if the U.S. Office of Personnel Management announces a federal government shutdown due to a lapse in appropriations by January 31, 2026, 11:59 PM ET, AND the specified party wins control of the U.S. House of Representatives in the 2026 midterm election. A "No" resolution for that specific outcome occurs if either the shutdown condition is not met or the specified party does not win House control. Resolution for House control may extend beyond the election date, potentially until January 4th of the following calendar year for independent caucus decisions or until a Speaker is elected.

Market Discussion
Traders in this market are predominantly discussing the likelihood of another US government shutdown by January 31, 2026, combined with which party will win the House in the 2026 elections. A strong consensus exists, with implied probabilities heavily favoring a scenario where a shutdown occurs and the Democratic Party wins the House. Arguments for this outcome point to persistent partisan disagreements over federal appropriations, particularly concerning immigration and DHS funding, and current generic ballot polling suggesting Democrats have a modest national advantage and are positioned to secure a majority in 2026.

Integrity risk· Large trades
Resolution quality is low (60), but Integrity averages all three scores, so the other two pull it up. Only a critically low score would cap the total.
Includes the cost to trade: a $10,000 order can't be filled here because the order book is too thin.
Weighted blend with hard caps — a critically weak safety pillar, or a severe trading anomaly, caps the total regardless of the rest. Full methodology · About the Trust Index
