World’s richest man, Elon Musk has offloaded company shares worth $5 billion, days after setting off a Twitter poll.

The Tesla CEO, after selling the shares, asked whether he should sell 10 percent of his huge stake in the electric carmaker.

According to regulatory filings made on Wednesday, with a net worth of around $300 billion, the billionaire, sold 4.5 million shares this week.

It was also revealed in the filings that in a bid to settle tax obligations, a batch of shares worth $1.1 billion were sold on Monday after Musk exercised stock options.

The sale was initiated under a pre-arranged trading plan set up in September.

It was not clear if the remaining share sales notified on Tuesday and Wednesday — around 3.6 million shares worth around $4 billion — were also planned ahead of the Twitter poll.

On Saturday Musk tweeted, “Much is made lately of unrealized gains being a means of tax avoidance, so I propose selling 10% of my Tesla stock. Do you support this?”

“I will abide by the results of this poll, whichever way it goes,” he added in another tweet after he posted the vote to his more than 62 million followers.

In the poll, almost 58 percent of 3.5 million votes were cast in favor of him proceeding with the sale.
