You think Dec 9 may have been chosen bc.:
- he will be done selling stock
- it's usually happy time when people may really bid up news and
- to have workforce celebrate Holidays?
12/9 is International Anti-Corruption Day
Most of his tweets lately have been about various forms of corruption.
He believes the SEC ("Shortseller Enrichment Commission") is corrupt and can "S Elon's C".
This whole thing has been tightly interwoven with the hullabaloo about his sale of stock.
Reference to Apollo 8, first trip to moon.
This suggests that it will be a 5:1 stock split as speculated and also some other big positive news, yet the SEC would have no legal recourse to stop this cryptic advance notice (I think, but IANAL). I doubt he'd bother with such a big buildup going maybe as far back as June 29th for an anticlimactic finish.
