US confirms Havana Syndrome–causing device by March 31?

This market will resolve to “Yes” if the President of the United States, any member of the Cabinet of the United States, any member of the Joint Chiefs of Staff, or any U.S. federal agency definitively states that a man-made device or weapon exists that is responsible for, or capable of causing, Havana Syndrome or Havana Syndrome-like symptoms by March 31, 2026, 11:59 PM ET.

The primary resolution source for this market will be official information from the government of the United States; however, a consensus of credible reporting will also be used.
