The founder of Tesla and SpaceX may complete the purchase of social network Twitter with more than half of the total value of the deal. Elon Musk has said he will go ahead with the tranche in his own funds, out of his own pocket or supported by third parties, and is negotiating the social network founder's participation in the transaction.

A document in the possession of the US market regulator noted Tuesday that Elon Musk will contribute $33.5 billion.

In this way, Musk would reduce some of the funding that comes from loans and specifically eliminate those that are tied to the equity of Tesla, the electric vehicle company from which much of his fortune comes.

The richest man on the planet also disclosed that he is negotiating with major Twitter shareholders, including founder Jack Dorsey, for the "possibility" of them exchanging their securities before the deal is completed.

Musk intends to take the company off the stock market and these shareholders would retain a stake in the social network.

Musk announced in April the purchase of Twitter, which will give him control of the company, disclosing that the transaction will be completed this year.
