According to the source, equity investors Sequoia Capital, Binance, Qatar Investment Authority, and others have received the appropriate paperwork for Musk's financial guarantee from his attorneys.

The move is Musk's most overt declaration yet that he plans to follow the judge's Friday deadline, which was imposed by a Delaware court.

The banks who agreed to lend money to Musk's purchase of Twitter have finished putting up the final debt financing agreement and are currently finishing the necessary paperwork, according to a report from Bloomberg News.

During a Monday video conference call with bankers who are helping to finance the deal, Musk promised to finalise the deal, the story stated.

Musk, the richest man in the world, has promised to contribute $46.5 billion in equity and debt finance for the acquisition, covering its $44 billion cost and closing expenses.

A total of 13 billion dollars in debt financing will be provided by banks, notably Morgan Stanley (NYSE:MS) and Bank of America Corp., to support the purchase (NYSE:BAC). As equity investors, Oracle Corp. co-founder Larry Ellison and Saudi Prince Alwaleed bin Talal will spend $7.1 billion. Months of speculation that Tesla Inc. (NASDAQ:TSLA) CEO Elon Musk will withdraw from the difficult acquisition will be put to rest after the deal is finalised.

In Wednesday's pre-market trade, Twitter shares were changing hands at roughly $53.18, and inching closer to Musk's offer price of $54.20. Once the purchase is finalised, months of rumours that the erratic entrepreneur would back out of the acquisition will come to an end.

Musk has positioned himself as a proponent of free speech and has criticised Twitter's policing of violent or abusive content tactics, which has led to the banning of numerous prominent Republican speakers.
