The wording of Trump’s post should be distinguished from claims that expand it into a legal declaration. On September 6, 2026, Trump posted content on Truth Social featuring the phrase “The Moon Is Ours.”
McGregor’s Response to Trump’s Post
According to MMA Sucka, Conor McGregor responded to Trump’s post about the Moon with a message suggesting that the sun belongs to Ireland. McGregor’s post was reportedly a response contrasting the Moon and the Sun, not confirmation that Trump’s wording constituted a legal declaration.

The Claim That the Moon Was Officially Declared U.S. Territory Is False
Fact-checking reports explained that online images and claims stating that Trump officially declared the Moon to be U.S. territory are false. The verifiable facts are that a post containing the phrase was uploaded and that McGregor responded with a message related to the Sun. The wording of the post and the legal-declaration claim rejected by fact-checkers should not be treated as the same thing. They are separate claims.
