I don't see any reference anywhere on this. And I'm not sure that it's easy to monetize his fortune that much. There will be a lot of inequality that affects his companies due to the fact that most of Elon's wealth is in liquid assets, not cash.

I also read this and indeed from the news I read he bought twitter with an Equity Funding Commitment of $21 Billion and the funding commitment came from several parties such as Bank Of America, MUFG, Barclays, Societe Generate etc. and the rest is from Morgan Stanley.
But indeed this is also there are several versions there but for sure it is not from cash but Elon Willing to do the debt for Twitter.
