Earlier on November 6, Musk asked his followers if he should sell 10% of his Tesla stock.
People are wondering if Musk really kept his promise? Well, it's tricky. According to the SEC filing, some of the stock sales were flagged as early as September. At least part of the sale was to satisfy tax obligations related to an exercise of stock options.
Earlier, Musk also fought with U.S. senator Bernie Sanders over taxing the super-wealthy.
Sanders, who is a strong proponent of taxing the super-rich like Musk demanded that "the extremely wealthy pay their fair share."
To which, Musk responded: "I keep forgetting that you are still alive."
In October, Musk said he would sell Tesla stock and donate if the World Food Program delivered a plan to solve world hunger.
News reports earlier that day suggested that a fraction of the world’s richest people could help solve world hunger.
