Oct 26 (Reuters) - Billionaire Elon Musk said he paid a visit to Twitter Inc's headquarters in San Francisco on Wednesday.

Ahead of a court-ordered deadline to close his $44 billion deal for the social media platform.

"Entering Twitter HQ – let that sink in!" said the caption of a video that Musk tweeted in which he was walking into the Twitter office carrying a sink in his hands.

Hours earlier, he hinted at being the company's top boss after updating his profile's bio to "Chief Twit".

The Wall Street Journal reported, Banks have started to send $13 billion in cash backing Musk's takeover of Twitter in a sign that the deal is on track to close by the end of the week.

Once final closing conditions are met, the funds will be made available for Musk to execute the transaction by the Friday deadline, the report added.

Earlier this month, Musk proposed to proceed with his original $44 billion bid, calling for an end to the lawsuit by Twitter.

Twitter shares were up about 1.1% at $53.91 in extended trading, slightly below Musk's offer price.
