The book There's Treasure Inside by Jon Collins-Black claims that there are five treasure chests hidden in the USA.

If the publisher or author announces that one of the treasures have been located before the end of 2025, this resolves Yes. The announcement must be linked in the comment section before the market closes. (If some people claim to have found the treasure before the end of the year, but there is no confirmation from the contest hosts, the resolution can be judged based on whether the claim looks legitimate...) If no such announcement is shared here, the market resolves No.
