Context
The probability for the headline scenario has settled at 85.5% updated 10 min ago. The market fuses two separate questions. The shutdown leg draws from the U.S. Office of Personnel Management’s operating status page: if OPM announces a federal government shutdown by 11:59 PM ET on January 31, 2026, that condition is met. Partial closures count, but weather or holiday office closures do not. The House control leg looks to the 2026 U.S. House elections on November 3, 2026. If one party holds more than half the voting seats, that party wins. Should the result be unclear, the market stays open until the Speaker of the House is elected and resolves to the Speaker’s party affiliation. The formal conditions that could shift the pricing are all tied to these resolution rules. The first deadline is January 31, 2026, when the shutdown window closes; the OPM status page is the definitive source. The second milestone is the 2026 House election on November 3, 2026, after which seat counts and, if necessary, the Speaker election will determine control. No other dates or events are specified in the market’s published terms.
FAQ
What defines a government shutdown in this market?
The market uses the U.S. Office of Personnel Management (OPM) operating status page. A federal government shutdown is triggered by a lapse in appropriations, and OPM’s announcement of such a shutdown qualifies. Partial shutdowns count, but office closures for holidays or inclement weather do not.
How is House control determined after the 2026 elections?
Control means holding more than half of the voting members of the U.S. House. If the outcome is ambiguous, the market remains open until the Speaker of the House is elected following the 2026 general election and resolves to the party the Speaker is affiliated with.
When does the shutdown portion of this market resolve?
It resolves based on whether OPM announces a shutdown by January 31, 2026, at 11:59 PM ET. If that date passes without such an announcement, the shutdown condition is not met.
What happens if the House outcome is disputed?
If the result is unclear after the election, the market stays open until the Speaker is elected. It then resolves to the party of the Speaker at the time of their election to that position.
Are both conditions required for this combined market to resolve to a particular outcome?
Yes, the market resolves according to the combined outcome: whether a shutdown occurs by the deadline and which party wins the House in 2026. Both parts must match the listed scenario.
