Will Anduril acquire Radiant Nuclear?
This market resolves YES if an official announcement is made by Anduril Industries stating that they are acquiring Radiant Nuclear. A tweet by the company's or Palmer Luckey's Twitter account, a blog post on their website, or an official press release is sufficient to meet this condition. The acquisition does not need to close this year, only an announcement is necessary.
Alternately the market resolves NO if there is no such announcement by the end of the year.
