Resolves YES if Elon Musk & OpenAI formally begin the process for Elon Musk or his associated companies to be—whether alone or as part of a consortium of other investors—the majority/controlling owner of OpenAI before market close (August 31st, 2025). Otherwise (including in the absence of any other information), resolves NO at market close.

It does not matter if the process is eventually blocked before it completes, there just needs to be a formal-ish announcement from both parties.

There are many edge cases I cannot specify in advance, so please ask clarifying questions if you are unsure. I plan to be fairly broad with how I define "Musk buying OpenAI"—the goal is to capture the spirit of the headlines.
