Tesla billionaire Elon Musk has launched a Twitter poll of his 62.6 million followers asking if he should sell 10% of his shares.
The vote, which closes later on Sunday, could see him dispose of $21bn (£16bn) of stock in the electric carmaker.
He promised to abide by the result of the poll, a response to a "billionaires tax" proposed by US Democrats.
The plan could see Mr Musk, who is one of the world's richest men, face a huge tax bill.
By late morning on Sunday, with about 8 hours to go before the poll closes, 57% of the 2.8 million respondents had voted "yes". (BBC news)
