Elon Musk hits Bill Gates below the belt with vulgar Tweet

Tesla CEO Elon Musk pushed back against fellow billionaire Bill Gates on Twitter after Gates seemed to downplay his attempt to short Tesla stocks Saturday, according to The New York Post.

Gates’ comments came during an interview with the French YouTuber HugoDécrypte, following Musk’s recent allegation against Gates that he was not serious about fighting climate change because he made a “half-billion dollar” bet against Tesla.

The Microsoft CEO argued that he put more money toward climate change than Musk or anyone else in the world, which cause Musk to respond with a “Sigh.”

“I give a lot more to climate change than Elon or anyone else,” Gates said. “I give a lot of philanthropic dollars, I back companies – you know electric cars are about 16% of emissions, so we also need to solve that other 84%.”

The diss exchange between the pair comes a month after Musk has confirmed that he rejected an opportunity to work with Gates on a philanthropic project late in April. Musk revealed the text conversation where he confronted gates over his purchase of $500 million in shorting stock against Tesla, and the pair appear to be set to meet before Musk asked Gates if he still had “half billion dollars short position against Tesla.”

“Sorry to say I haven’t closed it yet,” Gates responded. “I would like to discuss philanthropy possibilities.”

The exchange came just days before Musk posted what some called a vulgar tweet comparing Gates to the “pregnant man” emoji. Gates has not yet publicly commented on the tweet.
