Each answer resolves independently: YES if the event happens between 1 January 2027, 00:00 UTC and 1 January 2028, 00:00 UTC; NO otherwise. Events before 2027 do not count. Each answer resolves on whether the event happens during 2027, not whether it happens for the first time.

Actions by companies Musk leads or controls count as his.

Sources: official company statements and regulatory filings (SpaceX, Tesla, xAI, SEC, FEC), then reputable outlets (Reuters, Bloomberg, AP, WSJ; SpaceNews, NASASpaceFlight and Spaceflight Now for spaceflight answers), and Musk's own X posts where applicable. In case of ambiguity, I'll open a discussion before resolving.

I reserve the right to resolve any answer N/A for any reason, e.g. to deal with duplicates or abuse.

If you find any question to be ambiguous, please tell me and I will try to clarify.
