Musk had planned to use a margin loan to partially fund his purchase of the micro-messaging service.

According to a regulatory filing, Musk will provide an additional $6.25 billion in equity financing. The margin loan of the same size was reduced earlier this month.

The filing said that the chief executive was in talks with other investors about rolling their equity into the private company.

The original plan was for Musk to have $21 billion of equity and $12.5 billion in margin loans to complete the purchase. On May 5, he announced that he had secured equity commitments from other investors.

The richest person in the world is Musk with a personal fortune of $200 billion. He has a stake in the electric carmaker he co-founded.

In after-hours trading at 4:58 pm in New York, there was a 6.8% increase in the price of Twitter.

Musk wants to scrap the Margin Loan with new funding.
