Will any country expel a U.S. ambassador by December 31?

Resolution Criteria

This market will resolve to “Yes” if any U.S. ambassador is expelled from their assigned country by the government of that country between market creation and December 31, 2026, 11:59: PM ET. Otherwise, this market will resolve to "No". Any expulsion from a country where a U.S. ambassador is assigned as of the time of this market’s creation will qualify. For the purposes of resolving this market, an official announcement that a U.S. ambassador will be or is being expelled will suffice regardless of whether or not the respective ambassador leaves the country within this market’s timeframe. Qualifying announcements must be definitive, unambiguous, official statements issued by an authorized governmental person or entity. Whether the ambassador resigns, is recalled, or otherwise departs voluntarily will have no bearing on the resolution of this market. The primary resolution source for this market will be official information from the government of the United States, including the U.S. Department of State, as well as official information from the relevant expelling government; however, an overwhelming consensus of credible reporting may also be used.

Prediction markets show a minority of trading volume backing a 'Yes' resolution to this question — meaning most volume suggests no country will officially expel a U.S. ambassador before 31 December 2026. The market tracks any formal, government-issued expulsion announcement directed at a U.S. ambassador anywhere in the world. Resolution draws on official statements from the U.S. Department of State or the relevant foreign government, with credible media consensus as a fallback.

Market structure

This is a binary yes/no market with volume concentrated on the 'No' outcome. Resolution requires a definitive, official announcement of expulsion from an authorised governmental source — voluntary departures, recalls, and resignations do not qualify. The deadline is 31 December 2026 at 11:59 PM ET. The primary resolution sources are official U.S. and foreign government communications, supplemented by an overwhelming consensus of credible reporting if necessary.

Background

The expulsion of a diplomat — formally declaring them persona non grata — is among the most serious tools of statecraft a government can deploy. Such moves are relatively rare in relations with major Western powers but have historical precedent in periods of acute bilateral tension. U.S. ambassador expulsions have occurred sporadically over recent decades, typically in Latin America, Africa, or in states experiencing sharp deteriorations in relations with Washington. The current period is characterised by elevated geopolitical friction across multiple regions, including disputes over sanctions, military aid, trade policy, and sovereignty, which have strained U.S. bilateral relationships with a number of governments simultaneously. This broader context underlies the market's existence.

Key factors

Several structural factors bear on this market's resolution. First, the breadth of coverage: the United States maintains ambassadors in roughly 160 countries, meaning any one of those bilateral relationships deteriorating sufficiently could trigger resolution. Second, the political temperature of U.S. foreign policy matters significantly — changes in aid allocations, sanctions regimes, or public statements by U.S. officials can accelerate diplomatic crises. Third, domestic political pressures within host countries sometimes drive expulsion decisions, particularly where governments face nationalist sentiment or economic grievances linked to U.S. policy. Fourth, the resolution criteria require a definitive official announcement — ambiguous statements or media speculation do not qualify, raising the threshold for resolution. Fifth, timing matters: diplomatic crises can escalate rapidly but are also frequently resolved through back-channel negotiation before a formal expulsion is declared. Any single flashpoint — in Latin America, sub-Saharan Africa, the Middle East, or elsewhere — could move this market substantially.
