**Trader consensus strongly favors "No" (91.5%) because no formal US announcement or active pursuit of acquiring Chagos Islands territory has occurred, despite internal discussions and shifting positions on the stalled UK-Mauritius sovereignty transfer.** The British Indian Ocean Territory remains under UK control amid the suspended 2025 agreement, which would have transferred sovereignty to Mauritius while providing a 99-year lease on Diego Garcia for the joint US-UK military base. Trump initially signaled support for the deal in early 2025 but later criticized it publicly in January-February 2026 as an "act of great stupidity" and "total weakness," arguing leases are inadequate for strategic assets and linking the issue to broader national security concerns. The UK paused enabling legislation in April 2026 after US support was withdrawn, leaving the transfer on indefinite hold. Reports in June 2026 indicated the Trump administration considered options including a potential direct purchase from Mauritius (bypassing the UK) to secure permanent control of Diego Garcia, with Treasury Secretary Scott Bessent involved, but this was described as a non-leading proposal among several alternatives and drew no official confirmation or follow-through. Mauritius stated it received no such approach, and the islands are viewed domestically as not for sale. As of late August 2026, with a new UK prime minister facing UN pressure to advance the original deal, no acquisition announcement or bilateral purchase talks have materialized, and US policy has emphasized retaining operational security at the base without committing to territorial purchase. These factors—diplomatic impasse, absence of concrete US action on acquisition, and Mauritius's position—explain the market's assessment that an announcement before 2027 remains improbable under current conditions.

This market will resolve to "Yes" if the United States officially announces that at least some territory on the Chagos Islands will come under US sovereignty by December 31, 2026, 11:59 PM ET. Otherwise this market will resolve to "No".
Sovereignty is defined as the transfer of any of the Chagos Archipelago from either the United Kingdom or Mauritius to being under the formal governance or jurisdiction of the United States, either as a state, territory, or other classification within the US system. Basing rights, military leases, or access agreements alone do not constitute sovereignty transfer.
An official announcement made by the United States and either the United Kingdom or Mauritius that territory within the Chagos Archipelago will come under US sovereignty will qualify, even if the actual transfer of sovereignty is yet to occur or if such announcement is pending ratification, parliamentary approval, or other conditional legislative steps. Only announcements of official agreements or actions (e.g. executive order, signed legislation, etc.) will count - mere posts on Social Media will not.
