**Trump’s public criticism of the UK-Mauritius Chagos deal and the absence of any formal US acquisition proposal explain the 91.5% implied probability that he will not announce a purchase of part of the archipelago before 2027.** The UK signed the sovereignty-transfer agreement with Mauritius in May 2025, leasing Diego Garcia back for 99 years to protect the joint US-UK base. Trump initially backed the arrangement but reversed course by January 2026, labeling the handover an “act of great stupidity” on social media and urging the UK not to cede control. This shift prompted the UK to pause ratification by April 2026. In June 2026, media reports indicated the White House was examining options including a direct purchase from Mauritius to secure the base. Mauritius immediately stated it had received no official proposal and reiterated that its sovereignty claim remains non-negotiable. No subsequent diplomatic engagement, congressional action, or administration announcement has advanced a purchase track in the following two months. With the 2027 deadline approaching and no visible progress on bilateral talks or funding mechanisms, traders view an announcement as unlikely absent a major new catalyst.

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.
The resolution source for this market will be official information from the governments of the US, United Kingdom, or Mauritius, however a consensus of credible reporting confirming that land on the Chagos Archipelago has come under U.S. sovereignty will also qualify.**Trump’s public criticism of the UK-Mauritius Chagos deal and the absence of any formal US acquisition proposal explain the 91.5% implied probability that he will not announce a purchase of part of the archipelago before 2027.**
